MPRE success comes from rule sequence. Begin by identifying the lawyer’s role, the relationship, the duty category, and whether the lawyer must act, may act, or must not act. Then ask whether consent, writing, withdrawal, disclosure, screening, reporting, or court permission changes the result.

Mandatory duties include competence, diligence, communication, safekeeping property, avoiding frivolous claims, correcting false statements to tribunals, disclosing controlling adverse authority, reporting certain serious misconduct when confidentiality does not bar reporting, withdrawing when required, and protecting client interests upon termination.

Permissive rules include certain confidentiality disclosures, limited-scope representation with informed consent, withdrawal for specified good cause, and consentable conflicts with proper consent.

Prohibitions include unauthorized disclosure, nonconsentable conflicts, assistance in crime or fraud, false statements, false evidence, obstruction, improper contact with represented persons, commingling or conversion, misleading advertising, improper solicitation, and unauthorized practice.

High-yield MPRE traps include confusing confidentiality with privilege, forgetting client control over settlement and core criminal decisions, treating all conflicts as waivable, assuming third-party payers are clients, mishandling trust funds, ignoring tribunal candor, forgetting prosecutor duties, contacting represented persons, and overusing extreme answer choices.

The full Professional Responsibility framework is practical. Identify the actor, relationship, duty, and command. Then choose the answer that protects client autonomy, confidentiality, loyalty, tribunal integrity, public trust, and professional independence in the precise way the rules require.

The central lesson is disciplined professional judgment. A lawyer’s duties are not private instincts or personal preferences. They are enforceable professional obligations, and the MPRE tests whether students can apply them with accuracy.

Professional responsibility extends beyond courtroom advocacy. Lawyers must handle money and property properly, communicate truthfully with the public and nonclients, avoid misleading advertising, obey solicitation limits, clarify professional roles, support the legal system, and understand judicial ethics.

Client and third-party property must be kept separate from lawyer property. Client funds generally belong in trust, not in operating accounts. Commingling means improper mixing. Conversion means improper use. Unearned fees may need to remain in trust until earned. Settlement funds must be handled with notice, accounting, prompt distribution, and protection of valid third-party claims. Disputed funds must remain separated until resolved.

Lawyer advertising is allowed if truthful and not misleading. A lawyer may state fields of practice, but specialization claims must be accurate and properly supported. Solicitation is more restricted than advertising, especially direct live person-to-person contact for pecuniary gain toward someone known to need legal services in a particular matter. Coercion, duress, harassment, and unwanted solicitation are improper.

Referral and lead-generation arrangements must not mislead clients, compromise independence, or involve improper fee sharing. Firm names and professional communications must not misrepresent identity, affiliation, or responsibility for services.

A lawyer must be truthful in statements to others and must not knowingly make false statements of material fact or law. The lawyer must respect third-person rights and may not use methods that unlawfully burden, embarrass, delay, or invade legal rights.

Lawyers may serve as advisors, evaluators, negotiators, mediators, arbitrators, and third-party neutrals, but must clarify their roles. A mediator does not represent both parties merely by mediating. An evaluator must consider whether the evaluation is compatible with the client relationship and whether informed consent is required.

Lawyers have duties to the public and legal system, including access to justice, responsible conduct concerning appointments, avoidance of improper influence, and truthful statements about judges and adjudicative officers.

Judges must preserve independence, integrity, and impartiality. They must avoid impropriety and appearance concerns, regulate extrajudicial activities, avoid improper ex parte communications, disqualify themselves when impartiality might reasonably be questioned, and comply with rules governing gifts, public comments, and campaign activity.

The central lesson is that ethics is a full-profession system. Money, advertising, negotiation, nonclient communications, neutral roles, public duties, and judicial behavior all belong to Professional Responsibility.

Advocacy has boundaries. A lawyer may represent a client forcefully, but must not file frivolous claims, mislead courts, falsify evidence, obstruct discovery, coach witnesses to lie, improperly contact represented persons, or prejudice proceedings through public statements.

A lawyer must not bring or defend a proceeding or assert an issue without a nonfrivolous basis in law and fact. Good-faith arguments for changing the law are allowed. Criminal defense lawyers may require the prosecution to prove every element.

Candor to the tribunal requires truthful statements of fact and law, correction of prior material false statements, disclosure of controlling adverse legal authority not disclosed by the opponent, and refusal to offer evidence known to be false. If material false evidence has been offered, the lawyer must take reasonable remedial measures, which may include disclosure to the tribunal if necessary.

Ex parte proceedings require heightened candor because the opposing party is absent. The lawyer must disclose material facts needed for an informed decision, even if adverse.

Fairness to opposing parties and counsel prohibits obstruction of evidence, destruction or concealment of material, falsification of proof, assistance with false testimony, improper discovery conduct, and unsupported trial assertions.

Witness preparation is allowed; witness coaching is not. A lawyer may prepare a witness to testify truthfully but may not shape false testimony.

A lawyer must not communicate about the matter with a represented person without consent or legal authorization. With unrepresented persons, the lawyer must avoid implying neutrality and may generally advise only to seek counsel when interests may conflict.

Trial publicity is limited when public statements are substantially likely to materially prejudice a proceeding. Lawyers may provide certain basic information and may respond narrowly to undue prejudicial publicity.

A lawyer generally may not serve as advocate at a trial where the lawyer is likely to be a necessary witness, subject to limited exceptions.

Prosecutors have special duties as ministers of justice. They must not prosecute without probable cause, must respect counsel-related rights, must disclose exculpatory and mitigating evidence, and must avoid improper public condemnation of the accused.

The central lesson is that advocacy is controlled by truth, fairness, and institutional integrity. A lawyer may fight hard, but must not convert representation into deception, obstruction, or abuse.
