I. Introduction to Professional Responsibility
Governing Law: California lawyers are governed by the California Rules of Professional Conduct (CA Rules). Since 2018, CA Rules track the ABA Model Rules of Professional Conduct in numbering and content, but substantive differences remain that the bar examiners love to test.

Nature of Rules: PR rules are based on complex statutes and cannot be answered simply by relying on a general moral sense. Rules can be mandatory (subjecting a lawyer to discipline) or permissive (allowing, but not requiring, an action).

The "Five C's": Once a lawyer-client relationship forms, the lawyer is bound by five core duties: Competence, Communication, Confidentiality, avoiding Conflicts of interest, and Cash duties (integrity in fee arrangements and safeguarding client funds).

Professional Misconduct
Violating ethical rules is not the only way a lawyer can face discipline (fines, suspension, or disbarment). A lawyer can also be disciplined for:
1. Criminal Acts: Committing crimes that reflect adversely on the lawyer's honesty, trustworthiness, or fitness to practice (e.g., fraud, embezzlement, theft, tax evasion, assault, murder, domestic violence, drug use). Mere negligence (e.g., speeding) does not result in discipline. Acquittal in criminal court does not preclude professional discipline.

2. Fraud and Deceit: Noncriminal, civil conduct involving dishonesty, fraud, deceit, or intentional/reckless misrepresentation (e.g., selling a house knowing it has undisclosed mold).

3. Conduct Prejudicial to the Administration of Justice: Acts that reflect poorly on the profession, such as words or deeds demonstrating discrimination or bias.

4. Improper Influence: Suggesting the ability to improperly influence government decision-makers or assisting in judicial misconduct.

Forming the Lawyer-Client Relationship
When it Forms: The relationship begins when the client reasonably believes it does; the lawyer's subjective perception is irrelevant. No specific magic words, mutual consent, or written retainer agreement are needed.

Ambiguity: Any ambiguity about the relationship's existence is resolved in favor of the client and against the lawyer.

Quasi/Implied Relationship: This occurs when a lawyer's words or actions (e.g., inviting a client in, asking extensive questions, keeping confidential info, offering to consult a partner) lead the client to reasonably believe they are represented, even if the lawyer does not explicitly say so. This invokes all professional duties and liabilities, such as conflicts of interest and malpractice.

Accepting and Rejecting Clients
General Rule: A lawyer has no affirmative obligation to accept the representation of any client.

Exception (Court Appointments): A lawyer must accept a court appointment (e.g., pro bono for indigent defendants) unless there is good cause to decline. The Model Rules encourage 50 hours of pro bono work per year, which CA also supports.

Good Cause to Decline Appointment: 1) The lawyer lacks competence for the matter, 2) it would create an improper conflict of interest, or 3) it would impose an unjust financial burden on the lawyer.

Duty to Reject (Mandatory Rejection): A lawyer is affirmatively prohibited from accepting a client in two main scenarios:
1. Impaired Condition: The lawyer's physical or mental condition renders it unreasonably difficult to carry out the representation effectively.

2. Rule Violations: Accepting the client would violate the ethical rules or the law (e.g., lacking competence, conflicts of interest, revealing confidences).
ABA Model Rule: Requires actual knowledge that a violation will result. CA Distinction: Requires rejection if the lawyer knows or reasonably should know a violation will result.

CA Distinction (Frivolous Claims): CA explicitly requires declining representation if the lawyer knows or should know the client is bringing an action without probable cause to harass or maliciously injure someone. However, a good faith argument for an extension, modification, or reversal of existing law is acceptable.

V. Allocation of Control (Decision Making)
The allocation of control follows the "Means vs. Ends" test: the client determines the goals/ends, while the lawyer chooses the strategy/means.

• Mandatory Client Decisions (Ends): Certain core substantive rights are absolutely reserved for the client:
o Settlement: The client has the ultimate power to accept or reject settlements. The lawyer must communicate all bona fide settlement offers and cannot accept an offer without client consent. (Note: Opposing parties can enforce unauthorized settlements if the lawyer had "apparent authority").
o Criminal Cases: The defendant decides whether to plead guilty, waive a jury trial, or testify.

• Lawyer Decisions (Means): A lawyer is impliedly authorized to make tactical and procedural decisions, such as which witnesses to present, stipulating to uncontroverted facts, cross-examining, agreeing to continuances, or choosing which issues to raise on appeal.
o Limitation: A lawyer cannot impair the client's substantive rights or claim (e.g., stipulating to facts that foreclose a key defense, or conceding summary judgment against the client's interests). A lawyer may also limit the scope of representation with informed consent.

Counseling Crimes and Fraud
• Prohibited Conduct: A lawyer is absolutely prohibited from counseling or assisting a client in conduct the lawyer actually knows is a crime, a fraud, or a violation of a court order or professional rules. Doing so subjects the lawyer to professional discipline, civil, and criminal liability.

Permitted Conduct: A lawyer may discuss the legal consequences of proposed conduct or help a client determine the validity and scope of the law. A lawyer may also counsel a client who has committed past wrongful acts and wants to stop.

Ongoing Crimes: If a lawyer discovers that a client is using their services for ongoing criminal/fraudulent conduct (e.g., a Ponzi scheme), the lawyer must immediately cease all actions advancing the scheme and withdraw.

Terminating the Lawyer-Client Relationship
To withdraw, a lawyer must give the client timely notice and, if litigation is pending, obtain court approval. Sometimes a court will force a lawyer to stay on a case despite good cause to withdraw.

Mandatory Withdrawal (Required):
1. Continuing representation will result in a violation of the rules (CA Rule) or any law (ABA Rule).
2. The lawyer's physical or mental condition makes effective representation unreasonably difficult.
3. The client discharges/fires the lawyer.
4. CA Distinction: The client brings a malicious claim without probable cause to harass or injure someone.

Permissive Withdrawal (Discretionary):
1. Client conduct makes representation unreasonably difficult (e.g., verbal abuse).
2. The client fails to fulfill an obligation (e.g., not paying fees) after reasonable warning.
3. The client has used the lawyer's services in the past to perpetrate a crime or fraud.
4. Other "good cause" exists (e.g., irreconcilable conflicts over case management).
5. Distinction (Financial Burden): The ABA Model Rules allow withdrawal if representation poses an unreasonable financial burden; the CA Rules do not permit withdrawal for this reason.
6. Distinction (Frivolous Claim): CA specifically permits withdrawal if the client insists on asserting a frivolous claim or illegal conduct.

Post-Termination Duties: When the relationship ends, the lawyer must:
• Turn over all necessary client documents and property (lawyers may keep copies at their own expense).
• Maintain the confidentiality of all client information.
• Return any unearned advanced fees or client funds. (In CA, lawyers may keep a "true retainer" fee paid solely to ensure the lawyer's availability, if clearly understood by the client).

VII. Special Rules for Particular Lawyer Roles
While all lawyers are bound by general rules of professional responsibility, specific lawyering roles entail unique ethical constraints.

A. The Lawyer in an Advocacy Role (Litigation)
The advocacy context involves advancing a client's position against an adversary before a neutral arbiter, such as a judge.

Role of the Advocate: A lawyer acts as an agent to achieve a client's goals but does not step into the client's shoes or endorse their political, economic, social, or moral views.

Zealous Advocacy vs. Limitations: Lawyers must vigorously and zealously assert their client's position within the bounds of the adversary system, but they must not ignore other interests or values, such as respect for third parties and the public good. A lawyer may never break a rule of law or ethics to win, and is not required to press for every possible advantage (e.g., raising every available objection).

• Four Big Prohibitions in Advocacy:
1. Frivolous Claims: A lawyer is strictly prohibited from presenting a claim or defense that is not warranted under existing law or supported by a good faith argument for the law's extension, modification, or reversal.

CA Distinction: California additionally prohibits asserting a position, taking an appeal, or bringing an action without probable cause and for the purpose of harassing or maliciously injuring another person.

Criminal Defense Exception: Because liberty interests are at stake, criminal defense lawyers are given broader leeway to zealously defend their clients against the state, such as casting doubt on the credibility of a prosecutor's witness.

1. Unnecessary Delay and Expense: A lawyer may not use tactics that serve no purpose other than delaying proceedings or imposing unnecessary expenses on an adversary, such as burying them in extraneous discovery documents or asking for meaningless continuances.

2. Uncivil Conduct: Lawyers must act with dignity, courtesy, and integrity. Unnecessary hostility, disparagement of a judge or opposing counsel, name-calling, or rolling eyes can result in bar discipline.

3. Threats: A lawyer may not threaten anyone with criminal, administrative, or disciplinary charges to gain an advantage in a civil dispute or settlement negotiation.

B. The Lawyer as an Advisor or Counselor
Unlike advocacy, which resolves past disputes, advising involves guiding clients in their future behavior to conform to legal standards and minimize liability.

Independent Professional Judgment and Candid Advice: A lawyer must analyze legal risks and give the client a complete, accurate picture of the law. This requires rendering candid advice, which means delivering both good news and unwelcome news, such as negative legal precedents. A lawyer should not counsel acts that subject a client to liability without a good faith belief that it is in the client's best interest.

Imaginative Theories: Lawyers can be creative and provide advice contrary to the weight of authority, but their duty of candor requires them to inform the client of the risks and the likelihood that other legal actors may reach opposite conclusions.

Non-Legal Factors: In fashioning advice, lawyers are not restricted to legal factors; they may also consider moral, economic, social, and political factors relevant to the client's situation.

C. The Lawyer as a Third-Party Neutral (Arbitration & Mediation)
When acting as a mediator or arbitrator, the lawyer's goal is to neutrally guide parties to a resolution rather than advocate for them.

Duty to Clarify Role: The lawyer must explicitly inform unrepresented parties that she does not represent them. The lawyer must clarify this role if she knows or reasonably should know that any party misunderstands it, preventing inappropriate reliance on the lawyer.

Subsequent Representation Prohibited: A lawyer who served as a neutral third party cannot later represent anyone in connection with that specific matter, unless all parties to the proceeding provide informed written consent.

D. Lawyers Representing Organizations
These rules apply equally to "in-house" counsel (employed by the organization) and "outside" counsel (working in a law firm), despite differing practical pressures.

Defining the Client: The client is the organization or entity itself, acting through its highest authorized body (e.g., the board of directors), not its individual constituents, members, officers, employees, or shareholders. The lawyer must always act in the best interest of the organization at large.

Duty of Disclosure: If an organization's interests become adverse to an employee or constituent (e.g., an employee engaged in wrongdoing that exposes the firm to liability), the lawyer must clearly explain to that individual that the lawyer represents the organization and not the individual. Failing to do so could lead the employee to reasonably believe they are represented, creating an improper quasi-lawyer-client relationship and a conflict of interest.

Responding to Internal Wrongdoing ("Reporting Up"): A conditional, mandatory duty requires lawyers to report illegal activity up the organizational chain of command to protect the entity. Failing to report up when conditions are met is professional misconduct. The five conditions are:

1. Knowledge: The ABA Model Rule requires actual knowledge to a certainty of an act or omission. CA Distinction: The duty is triggered if the lawyer knows or reasonably should know of the violation. Mere suspicion is not enough under the Model Rules.

2. Related Matter: The act or omission must be related to the lawyer's representation of the organization.

3. Nature of Violation: The act must either violate the agent's fiduciary duty to the organization or be a legal violation that can be imputed to the organization (exposing it to liability).

4. Substantial Injury: The violation must be likely to result in substantial financial, reputational, or other injury to the organization itself.

5. Best Interests: It must be in the best interest of the organization to report the issue up the ladder (potentially to the highest authority) to prevent or minimize harm.

Reporting Outside the Organization ("Reporting Out"): This addresses what a lawyer may do if the highest authority does nothing to address a clear legal violation.

Model Rule: Contains a permissive exception to confidentiality. A lawyer may reveal confidential information externally to prevent reasonably certain substantial injury to the organization.

CA Distinction: California strictly prohibits reporting out. A lawyer's only recourse if the organization persists in illegal conduct is to withdraw, based on the theory that non-disclosure encourages corporate clients to be candid with counsel. Exception: If a federal law explicitly requires an attorney to report out, federal preemption protects the attorney from liability for doing so.

E. Supervisory and Subordinate Lawyers
Senior lawyers carry heightened ethical responsibilities for ensuring junior lawyers do a good job.

Policies and Procedures: Lawyers with managerial authority must make reasonable efforts to institute policies that detect and resolve conflicts of interest, track deadlines, appropriately account for client funds, and ensure inexperienced lawyers are adequately supervised.

Duty of Supervision: A senior lawyer with direct supervisory responsibility over a junior lawyer must provide appropriate oversight, support, and reasonable efforts to ensure the junior lawyer complies with ethical rules.

• Liability for Misconduct:
o Senior Lawyer Liability: A supervising lawyer is liable for a junior lawyer's professional misconduct if the supervisor knew of the misconduct when the consequences could have been avoided or mitigated, yet failed to take reasonable remedial action.

Junior Lawyer Liability: A subordinate lawyer must generally adhere to the rules and will be held personally responsible for clear ethical violations, even if acting under a senior lawyer's direct unethical request. However, a junior lawyer is not liable for a rule violation if they acted in accordance with a supervising lawyer's reasonable resolution of an arguable or ambiguous question of professional duty.

F. Prosecutors
Because prosecutors wield the enormous power to put individuals behind bars, their primary duty is to pursue justice, not merely to secure convictions. They have five specific additional obligations:

1. Probable Cause: Must not prosecute a charge they know is not supported by probable cause.

2. Right to Counsel: Must make reasonable efforts to assure the defendant's right to counsel.

3. Extrajudicial Comments: Must refrain from making public comments that have a substantial likelihood of heightening public condemnation of the accused, except when necessary to inform the public for a legitimate law enforcement purpose. They must also exercise reasonable care to prevent investigators and associated personnel from making such statements.

4. Disclosure of Evidence: Must timely disclose all evidence that tends to negate guilt or mitigate the offense.

5. Post-Conviction Evidence: If new evidence creates a reasonable likelihood of the defendant's innocence post-conviction, the prosecutor must promptly disclose it directly to the court and the defendant, and then undertake further investigation to determine if a wrongful conviction occurred.

VIII. The "Five C's": Competence and Communication
During the life cycle of representation, lawyers are bound by foundational rules encompassing the "five C's": Competence, Communication, Confidentiality, Conflicts of interest, and Cash-related duties.

A. The Duty of Competence
Competence is the minimal baseline of effective client service; falling below this baseline subjects a lawyer to professional discipline. A lawyer must apply the requisite skill, preparation, and organization to effectively carry out the client’s wishes.

1. Elements of Competence:
• Knowledge and Skill: A lawyer must possess the necessary degree of training and technical expertise for the representation. Whether a lawyer has the required knowledge depends on context-specific factors: the complexity or specialized nature of the matter, the lawyer's general experience level, the lawyer's specialized expertise, the amount of preparation the lawyer can give, and whether it is possible to associate with a more experienced lawyer.

Acquiring Competence: A lawyer who lacks competence at the outset may still take the case by either associating with a competent lawyer or acquiring the requisite knowledge through study and preparation. However, this preparation must not prejudice the client's interests (e.g., a lawyer cannot charge a client for months of preparatory study if a competent lawyer could do the work in a few weeks; the study must be done on the lawyer's own time).

Thoroughness and Preparation: Even with deep knowledge, a lawyer must carefully review the facts and law to present the best case possible. The required attention and preparation depend in part on what is at stake, with major litigation or complex transactions requiring more extensive treatment.

Mental and Physical Fitness: A lawyer must have the mental, emotional, and physical ability reasonably necessary to perform the services. It is never permissible to take on a case if the lawyer is not prepared to see it through due to these issues (e.g., an attorney requiring intensive treatment for alcoholism may not be able to competently represent clients during that time).

CA Distinction (Technology): As of March 2021, California explicitly requires lawyers to keep abreast of changes in the law and its practice, including the benefits and risks associated with relevant technology.

Strict Limitations and Exceptions:
• Client Consent Immaterial: A client can never consent to incompetent representation. A waiver or acknowledgment of the lawyer's incompetence does not insulate the attorney from discipline. If a lawyer is not competent and cannot become so, they must decline the representation or withdraw.

Exception for Emergencies: An incompetent lawyer may provide legal services in an emergency to the extent reasonably necessary. For example, a non-criminal lawyer may assist a criminal defendant in an urgent situation where substantial rights are at stake and no other lawyer is available.

B. The Duty of Diligence
Related to competence is the duty of diligence, which requires a lawyer to act zealously with commitment and dedication to the client's interests, and to avoid neglect, disregard, or unreasonable delays. Missing a court hearing without an excuse or failing to file a brief on time violates this duty.

Model Rule vs. California Distinction (Crucial Difference):
• ABA Model Rule: Operates as a strict liability standard. A lawyer is subject to discipline for any single action that falls below the standard of care for competence or diligence.
• CA Distinction: California protects lawyers from discipline for acts of mere negligence. Under CA Rules, a lawyer is only subject to discipline if they intentionally, recklessly, with gross negligence, or repeatedly fail to act competently or with reasonable diligence.

C. Consequences of Incompetence and Lack of Diligence
A lawyer who fails to meet the standard of care faces two entirely separate potential consequences:
1. Professional Discipline (State Bar):
• This is a penalty imposed by the state bar for violating an ethical rule.
• The bar brings an administrative/formal disciplinary proceeding where the lawyer is entitled to basic due process.
• Sanctions include censure, suspension, and disbarment.
• Key concept: A lawyer can face discipline even if the client suffers absolutely no damages.

Malpractice Lawsuit (Civil Court):
• This is a civil action brought by an aggrieved client in court to secure financial compensation (damages) for an injury.
• Theories of Liability: Malpractice can be proven through breach of contract (failing to provide promised competent services), breach of fiduciary duty (e.g., improper disclosure of confidential info or conflicts of interest), or negligence/breach of duty of care (failing to exercise the competence normally exercised by lawyers in similar circumstances).
• Requirements: Unlike professional discipline, a plaintiff in a malpractice lawsuit must prove causation and actual damages. A rule violation alone does not automatically give rise to a malpractice claim.

The Duty of Communication
To effectively serve a client, there must be a robust flow of information; the client must provide all necessary facts, and the lawyer must keep the client apprised to empower informed decision-making. While lawyers are busy and cannot communicate every insignificant detail, the rules strictly mandate prompt communication in five specific areas:

1. Disclosures and Client Consent: A lawyer must promptly inform the client of any decision or circumstance that requires the client's informed consent under the ethical rules, such as a conflict of interest.

2. Means Used to Represent: While clients dictate the goals, the lawyer must reasonably consult with the client about the means (strategy and tactics) used to achieve them. Even though the lawyer ultimately decides on issues like which witnesses to call, when to schedule depositions, or how to frame an argument, the lawyer must consult with the client before making these decisions if possible, or reasonably thereafter if prior consultation wasn't feasible (e.g., objecting during a live trial).

3. Significant Developments and Requests: The lawyer must keep the client reasonably informed about significant developments in the case and promptly comply with all reasonable requests for information, including requests for documents.

4. Rule Prohibitions: The lawyer must inform the client when ethical rules prohibit the lawyer from executing the client's wishes (e.g., informing the client that the lawyer cannot assist them in testifying falsely/committing perjury).

5. Informed Decision-Making (Settlements & Pleas): A lawyer must explain a matter to the extent necessary to allow the client to make informed decisions regarding the representation, such as fully explaining a confidentiality provision in a settlement.

CA Distinction: California explicitly requires that a lawyer must promptly communicate all terms and conditions of a proposed plea bargain in a criminal matter, and all terms and conditions of any written settlement offer in a civil matter.

IX. Duty to Preserve Confidentiality of Information
A. Overview and Definitions
Lawyer confidentiality is the essential cornerstone of the lawyer-client relationship, ensuring complete candor so the client can trust the lawyer, which in turn facilitates effective legal compliance and advice.
There are three analytically distinct doctrines that protect client secrets:
1. Work Product Doctrine (a rule of civil procedure).
2. Attorney-Client Privilege (a rule of evidence).
3. The Duty of Confidentiality (a rule of professional ethics enforceable by the state bar).

Definition of Confidential Information: It is broadly defined as any information acquired by the lawyer that is related to the representation and not readily available in the public domain. This includes information gained directly from client communications, but also through interviewing witnesses, conducting investigations, doing research, electronic/photographic evidence, lawyer observations, and anonymous tips.

B. Work Product Doctrine (Limit on Discovery)
This is a rule of civil procedure that protects certain materials from being subject to compelled disclosure to adversaries during discovery.
• Core Work Product: Protects documents prepared by a lawyer or their agent in anticipation of litigation that contain the lawyer's mental impressions, conclusions, opinions, or legal theories.
o CA Distinction: In California, core work product is never discoverable under any circumstances.

• Exceptions (When Work Product is Discoverable):
1. Lawyer is Target of Investigation: The doctrine does not apply to protect documents produced in connection with a crime or fraud in an official prosecution/investigation of the lawyer for knowing participation in that crime/fraud.

1.                 Not Related to Lawyer Effort: Documents that are not "core" work product (e.g., information obtained by an investigator) may be discoverable if a court determines that failing to turn them over would unfairly prejudice the seeking party or result in an injustice.

C. Attorney-Client Privilege (Evidentiary Privilege)
This rule of evidence blocks a court from compelling an attorney to disclose in discovery or testify at trial about confidences shared between the client, counsel, and privileged parties. The client technically holds the privilege and is ultimately in charge of asserting or waiving it, though the lawyer asserts it on their behalf.

Scope & Conditions for the Privilege to Attach:
• Communication: Must be an oral or written communication. General statements of law (e.g., "Robbery is a felony") are not privileged unless tied to the client's specific facts.

Privileged Parties: Must be between the lawyer and client, or agents essential to the delivery of legal services (associates, clerks, paralegals, investigators, experts). It also covers the client's agents necessary to provide support (e.g., translators, doctors). It applies to organizational clients (authorized conversations between corporate employees and the lawyer).

Made in Confidence: The parties must reasonably believe the communication is private (e.g., not in a crowded elevator or an email thread with unnecessary third parties). An eavesdropper listening in on a reasonably private conversation does not break the privilege.

Seeking Legal Advice: The communication must be for the purpose of seeking or providing legal advice/representation.

Exclusions: The privilege does not apply to business or personal advice. It also generally excludes the client's identity, whereabouts, fee arrangements, and the general purpose of the lawyer's work.

Waiver of the Privilege: Waiver occurs after the privilege attaches, destroying the protection.
Deliberate Disclosure: The lawyer or client deliberately disclosing the communication to a third party waives it. Selective disclosure (revealing parts to gain a settlement advantage while hiding other parts) generally waives the privilege for the entire communication, as courts prohibit using the privilege as both a "sword and a shield".

Inadvertent Disclosure: Accidentally sending privileged info (e.g., via email) waives the privilege unless the lawyer makes prompt efforts to rectify the mistake.

Inaction: Failing to object to the admission of privileged testimony at trial.

Exceptions (The Privilege Never Attaches):
• Self-Defense/Legal Dispute: If a client sues the lawyer (e.g., malpractice), relevant communications are not privileged.

Joint Clients: If a lawyer represents joint clients who later sue each other over the subject matter of the joint representation, their communications with the lawyer are not privileged in that dispute.

Deceased Client's Estate: Privilege does not apply to communications relevant to a dispute among a deceased client's heirs over the estate. (Otherwise, the privilege generally survives death).

Crime/Fraud Exception (Heavily Tested): The privilege does not apply if the client seeks the lawyer's services in furtherance of a crime or a fraud (knowing/reckless misrepresentation likely to injure another).

Client's Intent: It only matters that the client intended to commit the act; it is entirely irrelevant if the lawyer knew about the intent or intended to help.

CA Distinction (Timing): In CA, the client's intent must be formed before the communication occurs.

Success Irrelevant: It applies even if the client gets sick and never actually commits the crime/fraud.

Future vs. Past: It only applies to ongoing and future criminal/fraudulent activity. Communications seeking help for a past crime remain fully privileged.

Burden of Proof: The party seeking to compel disclosure holds the burden. CA Distinction: They must show a reasonable person would have a reasonable basis to expect the perpetration/attempt of the crime/fraud.

The Duty of Confidentiality (Ethical Rule)
This rule prohibits a lawyer from disclosing any information relating to the representation unless an exception applies or the client gives informed consent.

Scope: It is much broader than the privilege. It applies to prospective clients (even if a relationship never forms), and it lasts indefinitely, surviving both the end of the representation and the client's death.

• Discretionary Nature: Revealing confidences under an exception is almost always discretionary (the lawyer may reveal, but is not punished for staying silent).
o Model Rule vs. CA Distinction: The ABA Model Rules have one mandatory disclosure (client perjury). In California, there are no mandatory disclosures, even for perjury.

Exceptions (When a Lawyer May Disclose):
1. Client Consent: Explicit or implicit (e.g., authorizing a lawyer to negotiate a plea deal implies consent to share certain facts).
o Model Rule: Requires informed consent confirmed in writing (oral consent + confirmatory memo from lawyer is sufficient).
o CA Distinction: Requires informed written consent (must be a document explicitly signed by the client).

1. Preventing Death or Substantial Bodily Harm: Both jurisdictions allow disclosure to protect third parties, but with massive differences.

Model Rule: Lawyer may reveal if they reasonably believe it is necessary to prevent reasonably certain death or substantial bodily harm. No criminal act is required (e.g., Spalding v. Zimmerman scenario: lawyer can reveal an opponent's life-threatening medical condition discovered during a medical exam). No prior steps to notify the client are required.

CA Distinction: Much more restrictive. The lawyer may reveal only to prevent a criminal act that is reasonably believed likely to result in death/harm. Furthermore, the lawyer must make a good faith effort to prevent the act/persuade the client, must notify the client of the decision to disclose, and must disclose no more information than necessary.

3. Financial Injury (The "Enron Rule"):
o Model Rule: A lawyer may disclose to prevent, mitigate, or rectify substantial harm to the financial interests or property of another caused by a client's crime or fraud, if the client used the lawyer's services in furtherance of it.
o CA Distinction: California strictly forbids disclosure to prevent financial injury. CA is the only state without this exception.

1. Lawyer for Organization: Reporting out to prevent financial injury to the entity itself.

5. Other Exceptions:
To secure legal advice regarding the lawyer's compliance with ethical rules.

Exception: To establish a claim or defense in a dispute with the client (e.g., malpractice or fee disputes).

Exception: To comply with any other law or court order (e.g., if subpoenaed to testify under the crime/fraud exception to the attorney-client privilege, the ethics rule allows the lawyer to comply with the court order without facing bar discipline).

CA Distinction: While these last three exceptions are explicitly written into the ABA Model Rules, they are not listed in the CA Rules but are nonetheless established and permitted by California caselaw.

X. Conflicts of Interest
Alongside confidentiality, the duty to avoid conflicts is a cornerstone of the lawyer-client relationship, grounded in the lawyer's foundational duty of loyalty. Lawyers must pursue the client's interests with single-minded focus and avoid relationships that undermine trust or impair effective representation.

If a lawyer has a conflict, it does not automatically disqualify them, but requires them to assess if the risks can be managed with client consent. Proceeding with an unconsented or non-consentable conflict subjects the lawyer to bar discipline, mandatory withdrawal, malpractice lawsuits, and court disqualification. California rules largely track the ABA Model Rules, with a few heavily tested distinctions.

A. Concurrent (Present) Conflicts of Interest
A concurrent conflict exists if a lawyer's representation triggers either "Direct Adversity" or a "Material Limitation". The rules protect the core values of confidentiality and loyalty.

1. Types of Concurrent Conflicts:
• Direct Adversity: Occurs when the interests of one client are in direct conflict with another. What is good for one is by definition bad for the other.
o Examples: Client A is suing Client B; A is testifying against B; A and B are co-defendants blaming each other; representing a buyer and seller of the same property.
o Unrelated Matters: Direct adversity exists even if the lawyer represents the clients in totally unrelated matters (e.g., representing A in a business deal, but representing B to sue A for breach of contract).

Material Limitation: Occurs when there is a significant risk that the lawyer's representation will be materially limited by their responsibilities to/relationships with another client, a former client, a third person, or the lawyer's own personal interests.

The risk must be significant, and the limitation must actually have the potential to palpably harm the client's interests (e.g., going easy on a corporation because the lawyer's husband is an investor).

Positional Conflicts: Occurs when a lawyer advocates a legal position for Client A that is contrary to the position taken for Client B (e.g., arguing a statute creates strict liability for A, but denying it for B). This is treated as a material limitation conflict. To determine if it materially affects representation, the bar looks at where the cases are pending (e.g., Supreme Court precedent), substantive vs. procedural issues, timing, and significance to the clients.

Resolving Concurrent Conflicts:
Never Consentable (Absolute Prohibitions): A lawyer may never represent opposing parties in the same lawsuit, or co-defendants in a capital criminal case.

Consentable Conflicts: Outside of the absolute prohibitions, a lawyer may undertake representation despite a conflict if two conditions are met:

1. Reasonable Belief: The lawyer must reasonably believe she can provide competent and diligent representation to each affected client.

2. Informed Consent: The lawyer must provide adequate information about the material risks and reasonable alternatives, and obtain consent from each affected client.
 ABA Model Rule: Requires informed consent confirmed in writing (oral consent followed by a confirmatory memo is sufficient).
 CA Distinction: Requires informed written consent (must be a physical document explicitly signed by the client).

3. CA Distinction: Mandatory Written Disclosure Under California rules, even if there is no significant risk of a material limitation, a lawyer must still provide written disclosure (no client consent required) if:

The lawyer (or another lawyer in their firm) has a relationship (legal, business, financial, personal, or other) with a party in the same matter.

The lawyer knows or should know that opposing counsel has such a relationship with the lawyer or their firm (e.g., lawyer is married to opposing counsel, or opposing counsel is the lawyer's brother).

Note: The lawyer must still reasonably believe they can provide competent and diligent representation.

B. Past (Successive) Conflicts of Interest
Loyalty obligations end when the representation ends, but the duty of confidentiality remains.
• The Rule: A lawyer may not represent a new client against a past client if two conditions are met:
1. The matters are the same or substantially related, AND
2. The new client's interests are materially adverse to the old client's interests.

Substantially Related: Means the matters share the same factual context. The test is whether there is a substantial risk that confidential information obtained in the old matter would materially advance the new client's position. (e.g., setting up a business for A five years ago, and now representing B in suing A over that same business).

Waiver: The past conflict can be waived if the past client gives informed consent, confirmed in writing.

Imputed Conflicts (Law Firms)
If one lawyer in a firm is conflicted, the entire firm is disqualified from representing the client, unless an exception applies.

While Associated (New Lawyer Joins Firm): If a new lawyer joins a firm with a conflict from a prior firm, the new firm can still represent the client only if:
1. The conflicted lawyer did not substantially participate in the matter at the prior firm.
2. The conflicted lawyer is timely screened from the current matter and receives no part of the fee.
3. Written notice is given to the former client describing the screening process.
o Exception: If the prohibition is based solely on a personal interest of the prohibited lawyer that will not materially limit the other lawyers, the firm is not conflicted.

• After Association (Lawyer Leaves Firm): When a lawyer leaves, the old firm may represent a client with interests materially adverse to the departed lawyer's former client, UNLESS the matter is the same/substantially related and any remaining lawyer in the firm still has confidential information regarding it. (Requires informed consent confirmed in writing to waive; informed written consent in CA).

D. Special Rules for Financial and Personal Conflicts
These rules specifically police a lawyer's financial and personal relationships with clients.

1. Financial Relationships:
• Third-Party Payment: A lawyer cannot accept payment from someone other than the client unless: 1) the third party does not interfere with the lawyer's independent judgment, 2) client confidentiality is protected, and 3) the client gives informed consent (CA requires informed written consent). (Exception: Public agencies paying for legal aid).

Aggregate Settlements/Pleas: Prohibited for multiple clients unless each client gives informed consent in a signed writing. (Exception: court-approved class actions).

• Malpractice Liability:
o Waiving/Limiting: Under ABA Model Rules, a lawyer can prospectively limit malpractice liability only if the client is represented by independent legal counsel. CA Distinction: A lawyer cannot contract to limit malpractice liability at all, regardless of independent counsel.

Settling Claims: A lawyer can only settle a malpractice claim if they advise the client in writing to seek independent counsel and give them a reasonable opportunity to do so.

• Interest in Lawsuit (Proprietary/Media):
o ABA Model Rule: A lawyer may not acquire a proprietary interest in the subject of a lawsuit, nor acquire media/publication rights to a client's story before representation concludes.
o CA Distinction: California does not prohibit acquiring proprietary interests or media rights prior to conclusion.
o CA Distinction (Property): CA specifically prohibits a lawyer from purchasing property in a proceeding (e.g., probate, foreclosure) if affiliated with a party.

Business Transactions with Clients: Strictly prohibited unless: 1) terms are fair and reasonable, 2) terms are fully disclosed in writing, 3) the client is advised in writing to seek independent counsel, and 4) the client gives informed written consent. (Does not apply to standard reasonable contingency fee contracts).

Soliciting Gifts: A lawyer may not solicit a substantial gift or draft a legal instrument (like a will) giving the lawyer a substantial gift, unless related to the client.

• Financial Assistance to Clients: Generally prohibited in connection with litigation.
o Exceptions: Lawyers may advance litigation expenses for indigent clients (repayment can be contingent). ABA rules now allow modest gifts to meet basic needs of indigent clients (but lawyers cannot advertise this). Loans unrelated to the legal matter are permitted if they meet the rigorous rules for business transactions.
o CA Distinction: CA allows lawyers to provide financial assistance for any expenses incurred in promoting or protecting the client's interests, not just litigation expenses.

Personal Relationships:
• Sexual Relationships: Both jurisdictions permit consensual sexual relationships that predate the legal representation. However, beginning a sexual relationship after the lawyer-client relationship forms is strictly prohibited; the lawyer cannot condition representation on sex and must withdraw. This applies to organizational clients (lawyers cannot have sex with a constituent who supervises or consults with the lawyer).

• Trial Counsel as Witness: A lawyer is generally prohibited from acting as an advocate in a trial where they are likely to be a witness. Exceptions apply if the testimony is about an uncontested issue or the value of legal services provided.
o CA Distinction: California allows the client to waive this conflict with informed written consent. The ABA Model Rules do not permit client waiver.

XI. Cash-Related Duties: Legal Fees
Lawyers may charge fixed fees (a flat rate or hourly rate regardless of outcome) or contingency fees (paid only if the lawyer wins a favorable outcome or settlement).

A. Evaluating Fees (Model Rule vs. California)
• ABA Model Rule (Must be "Reasonable"): A fee violates the rule if it is unreasonable. Reasonableness factors include: the time, labor, and skill required; novelty/complexity of the case; likelihood it precludes the lawyer from other work; customary local market rates; amount in controversy and results obtained; time limitations imposed; nature and length of the client relationship; and the lawyer's experience/reputation.

CA Distinction (Must not be "Unconscionable"): California has a much higher threshold for discipline; a fee must "shock the conscience". California considers all the Model Rule factors plus three additional ones: 1) whether the lawyer engaged in fraud or overreaching, 2) whether the lawyer failed to disclose material facts, and 3) the relative sophistication of the lawyer and the client.

Form of the Fee Agreement
• Non-Contingent/Fixed Fees:
o Model Rule: Generally does not require a written agreement (though preferred). The scope and rate must be communicated within a reasonable time, unless the lawyer regularly represents the client.
o CA Distinction (Writing Requirement): CA requires a written fee agreement if it is reasonably foreseeable that total expenses will exceed $1,000, or for any non-refundable retainer (a fee paid solely to ensure availability). Unwritten agreements are voidable by the client, though the lawyer can still recover a "reasonable fee".
o CA Exceptions: No writing is required in CA if the fee is under $1,000, in emergencies, for routine work for a regular client, or if the client is a corporation.

• Contingency Fees (Strict Writing Requirements):
o Both jurisdictions strictly prohibit contingency fees in family law (divorces, alimony, child support) and criminal defense cases.

If a lawyer is fired before a contingency case concludes, they may recover fees in quantum meruit (in proportion to the work completed) from any eventual recovery.

Model Rule Requirements: Must be in writing, signed by the client, state the rate, and explicitly detail how costs and expenses are paid and calculated (e.g., whether costs are deducted before or after the lawyer's percentage is taken).

CA Distinction: Must be signed by both the lawyer and the client. Additionally, the CA contract must explicitly state that the contingency rate is negotiable, specify if the client must pay additional compensation for related matters outside the core representation, and it may provide for an attorney's lien against the recovery.

Fee Splitting & Referral Fees
• Splitting Fees Between Lawyers in the Same Firm: Always permitted.
• Splitting Fees with Lawyers Outside the Firm:
o Model Rule: Allowed if the total fee is reasonable, the client gives written disclosure and consent, and the split is strictly proportional to the services rendered (or both lawyers assume joint responsibility).
o CA Distinction: Allowed if the client gives written disclosure and consent (detailing the lawyers and terms), there is a written agreement to divide fees, and the total fee is not increased solely due to the split. Proportionality is not strictly required in CA.

• Splitting Fees with Non-Lawyers: Generally strictly prohibited to protect the lawyer's independent judgment.
o Exceptions: Death benefits paid to a deceased lawyer's heirs, compensation/pension plans for firm employees (paralegals/secretaries), and sharing fees with a non-profit organization that employed/recommended the lawyer. (Note: MR limits this to court-awarded fees; CA allows sharing any settlement fees with the non-profit).

• Referral Fees: Paying someone simply for referring a client is prohibited.
o Exceptions: Lawyers may participate in qualified, public-serving lawyer referral services. They may also enter non-exclusive "reciprocal referral" agreements with other lawyers or non-lawyers, provided the client is informed and no actual money changes hands for the referral. Nominal gifts for a recommendation are allowed if not intended as payment or an encouragement for future referrals.

Client Property & Trust Accounts
A lawyer acts as a fiduciary and must safeguard client property with the utmost care.

Client Trust Accounts: All client money must be placed in a separate, identifiable bank account.

• No Commingling: A lawyer cannot mix personal or firm funds with client funds.
o Exceptions: A lawyer may deposit their own funds solely to pay bank charges. If a settlement is deposited containing both the client's award and the lawyer's fee, the lawyer must withdraw their portion at the "earliest reasonable time." If a fee is disputed, the disputed portion must remain in the trust account until resolved.

• Advance Fees (Flat Fees) Distinction:
o Model Rule: Unearned advanced flat fees must be kept in the trust account and only withdrawn as earned.
o CA Distinction: A lawyer may place advance flat fees directly into their operating account if they provide written notice to the client regarding their right to a trust account and a refund of unearned fees. If the fee exceeds $1,000, the client's consent to use the operating account must be in writing.

• Record-Keeping & Other Property: Records for all trust accounts must be kept for 5 years. CA additionally requires specific written ledgers for clients and written journals for bank accounts. Physical property (e.g., stock certificates) must be identified, put in a safe deposit box, recorded for 5 years, and promptly distributed when requested.

XIII. Rules of the Legal Marketplace
A. Lawyer Advertising (Commercial Speech)
Advertising is widely distributed communication with the public. It is constitutionally protected commercial speech subject to intermediate scrutiny.

The Rule: A lawyer may advertise through any media, provided it identifies at least one responsible lawyer/firm and is not deceptive, false, or misleading.

Misleading Statements: Includes material misrepresentations or omissions. Creating unjustified expectations (e.g., "I get huge recoveries fast"), unsubstantiated comparisons ("I am the best"), or sensational images (pitbulls/giants) are prohibited. Testimonials and dramatizations must include explicit disclaimers.

Specializations: A lawyer may claim to be a "specialist" based on experience, but may only claim to be a "certified specialist" if they hold a certificate from a state-bar-recognized entity, and the advertisement must name that entity.

B. Solicitation
Solicitation is targeted communication directed at a specific individual known to need legal services.
• Direct, For-Profit Solicitation (Prohibited): Live, person-to-person contacts (in-person, live telephone, or real-time electronic) motivated by pecuniary gain are strictly prohibited.
o Exceptions: Permitted if the target is another lawyer, a routine business user of such services, or has a prior family/personal/professional relationship with the soliciting lawyer (provided there is no coercion or harassment).

• Indirect or Not-For-Profit Solicitation (Permitted): Solicitations by mail/email (indirect) or for political/non-profit causes (strict scrutiny applies) are generally permitted, as the recipient can easily ignore them.
o Prohibitions: Cannot solicit if the target has made known a desire not to be contacted, or if it involves coercion, duress, or harassment.
o CA Distinction ("Advertisement" Label): CA requires targeted mailings/communications to clearly state the word "ADVERTISEMENT" on the outside envelope and at the beginning/end of the message, unless the target is a lawyer or has a prior relationship.

Agents (Runners and Cappers): Lawyers cannot hire agents to troll hospitals or courthouses to directly solicit clients on their behalf. What a lawyer cannot do directly, they cannot do through an agent.

Group Plans: Lawyers may participate in prepaid or group legal service plans that directly solicit memberships.

C. Unauthorized Practice of Law (UPL)
Only admitted lawyers may practice law (giving advice applying law to specific facts). In CA, UPL is a criminal misdemeanor.

Unlicensed Practice: It is UPL to practice or establish a continuous presence in a state where one is not licensed.

Temporary Practice Exceptions: Out-of-state lawyers may practice temporarily if admitted pro hac vice by a judge, participating in arbitration, working in legal aid, serving as in-house counsel, or working on transactions tied to their home state.

Assisting Non-Lawyers: A lawyer commits UPL if they allow a non-lawyer (e.g., a paralegal) to give legal advice to clients without supervision.

Law Firm Structure & Non-Legal Services
• Non-Lawyer Ownership: A lawyer may not practice in an entity if a non-lawyer owns any part of it, holds a managerial/director position, or has the right to control professional judgment. Exceptions exist for non-profits and working as an employee (in-house counsel) for a corporation.

• Mixed Legal and Non-Legal Services:
o Model Rule: If a lawyer provides law-related services (e.g., tax prep, financial planning) distinct from legal services and clarifies this to the client, the PR rules do not apply to the non-legal services. If they are mixed and indistinguishable, the rules apply to everything.
o CA Distinction: The CA Rules of Professional Conduct apply to everything a lawyer does when serving a client, regardless of whether the specific service is legal or non-legal.

E. Sale of a Law Practice
Selling a practice is permitted if clients receive proper notice and fees are not increased due to the sale.
• Model Rule: A lawyer may sell specific, individual practice areas. If selling the entire practice, the lawyer must cease practicing law.
• CA Distinction: The sale must be "all or nothing" (the entire practice or substantially all of it; no cherry-picking lucrative matters). However, the selling lawyer is not required to stop practicing law elsewhere.

XIV. Non-Client Duties
While a lawyer owes primary duties of loyalty and confidentiality to their client, these obligations are limited by rules designed to protect the integrity of the legal system and ensure fair play.

A. Duties to Other Parties in Legal Matters
1. Communications with Third Parties
• False Statements: A lawyer must avoid knowing falsehoods (the "golden rule" of transactions). A lawyer must not knowingly make a false statement of material fact or law to a third person, or fail to disclose material facts necessary to avoid assisting a client in a crime or fraud (subject to confidentiality rules).

Actual Knowledge Required: The rule only applies to knowing falsities; suspecting a statement is false without actual knowledge is not a violation.

Materiality: Whether a statement is a "material fact" depends on the context. For example, in negotiations, estimates of price are typically not considered material facts because parties expect inflation for leverage.

Duty to Disclose: A lawyer must disclose material facts if a third party is laboring under a misapprehension that goes to the heart of the bargain and uncorrected non-disclosure would result in substantial unfairness (amounting to assisting client fraud).

Communications with Represented Parties
• The Rule: A lawyer is strictly prohibited from communicating directly or indirectly about the subject matter of the representation with a person the lawyer knows is represented by another lawyer, unless the lawyer has the consent of that person's lawyer.

Actual Knowledge & Timing: The lawyer must have actual knowledge of the representation. If a lawyer discovers a party is represented mid-conversation, they must immediately terminate the conversation.
