Informed Consent in Legal Ethics

Meaning of informed consent

Under ABA Model Rule 1.0(e), informed consent is a person’s agreement to a proposed course of conduct after the lawyer communicates adequate information and explanation about its material risks and reasonably available alternatives. The person must understand what is being proposed and what meaningful choices exist. A signature, a general waiver, or the client’s silence does not by itself establish informed consent.

The communication needed depends on the rule and facts. A client asked to waive a conflict may need to understand divided loyalty, what information could be shared or withheld, how counsel’s ability to advocate may be limited, and the practical alternative of separate counsel. A client asked to approve a limited scope should understand which tasks the lawyer will handle and which remain the client’s responsibility. The lawyer must explain enough for a reasoned choice, not recite a form.

Informed consent and written confirmation are separate ideas. Some rules require consent confirmed in writing, while others require a signed writing or consent itself in writing. Under Rule 1.0(b), “confirmed in writing” means the client gives consent in writing or the lawyer promptly sends a writing confirming oral consent. If neither is feasible at the time, the writing must follow within a reasonable time. A writing records consent; it does not supply missing information or make a prohibited course permissible.

Explain the decision the client is actually making

Start by stating the proposed action in concrete terms. Then describe material risks and reasonably available alternatives in language the client can understand. “There may be a conflict” is rarely enough if counsel already knows the conflict’s nature. Explain who the other client is, how the interests differ, what counsel can and cannot do for each person, and what happens if the clients later disagree.

The lawyer need not describe every remote possibility. The focus is on risks material to the choice and alternatives reasonably available in the circumstances. If a client already has independent counsel, the lawyer can generally assume that the client has received adequate information from that counsel, though the lawyer should still communicate what the applicable rule requires.

Consent usually requires an affirmative response. A lawyer may not infer consent merely because a client did not object to an email or signed a general engagement letter. Informed consent can sometimes be inferred from conduct when the person has reasonably adequate information, but an express response is the sound course and rules often require a particular writing.

Conflicts under Rule 1.7

Rule 1.7 permits representation despite a concurrent conflict only if every condition in paragraph (b) is met: the lawyer reasonably believes competent and diligent representation can be provided to each affected client; the representation is not prohibited by law; it does not involve one current client asserting a claim against another current client represented by the lawyer in the same litigation or proceeding; and each affected client gives informed consent confirmed in writing.

That final condition cannot repair failure of the first three. If competent representation is not reasonably possible, no waiver allows the lawyer to continue. A current client’s claim against another current client in the same proceeding is nonconsentable under the ABA Model Rule. Consent also does not excuse the lawyer from independently protecting each client’s information and loyalty.

Example: a firm represents a buyer and seller in a planned business transaction. Before asking for consent, counsel explains the clients’ competing priorities, the possibility that negotiating a benefit for one will reduce the other’s protection, how joint representation affects confidentiality, and the option of separate counsel. If counsel reasonably believes both clients can receive competent and diligent representation and no nonconsentable bar applies, each may decide whether to proceed. A generic sentence that “conflicts may arise” does not communicate this transaction’s risks.

Informed consent can become stale when the facts change. A client who approved joint advice about a routine lease has not necessarily agreed that the same lawyer can later represent the landlord against that client in a dispute. When a new conflict emerges, explain the new situation and reassess consentability. A prospective waiver cannot automatically cover every unknown future dispute.

Limited-scope representation

Rule 1.2(c) permits a lawyer to limit the scope of representation if the limitation is reasonable under the circumstances and the client gives informed consent. The lawyer should define the task and boundaries clearly. For example, a lawyer might agree to review a settlement agreement but not negotiate it or attend a hearing. The client needs to know that the lawyer will not monitor deadlines or take the unassigned next steps unless separately agreed.

A limitation is not reasonable just because a client wants to pay less. If the proposed narrow task would leave the lawyer unable to provide competent advice for the objective the client seeks, the lawyer must explain the problem and decline or broaden the engagement. Nor can the lawyer limit representation in a way that effectively assists crime or fraud or avoids a nonwaivable duty.

The client should understand what the lawyer will do, what remains undone, the consequences of the boundary, and any available fuller representation. Written scope terms help avoid later disputes, even when a particular rule does not require the consent itself to be in a signed writing.

Specific rules requiring informed consent

Third-party payment

Under Rule 1.8(f), a lawyer may accept payment from someone other than the client only if the client gives informed consent, the payer does not interfere with professional judgment or the lawyer-client relationship, and information relating to the representation remains protected under Rule 1.6. A parent paying an adult child’s legal bill does not become the lawyer’s client or gain access to confidential strategy. The lawyer should tell the client who is paying, identify any conditions, and reject interference.

Business transaction with a client

Rule 1.8(a) imposes more than a generic consent standard when a lawyer enters a business transaction with a client or knowingly acquires an ownership, possessory, security, or other pecuniary interest adverse to the client. The terms must be fair and reasonable and fully disclosed in a writing the client can reasonably understand; the client must be advised in writing of the desirability of independent counsel and given a reasonable opportunity to seek it; and the client must give informed consent in a writing signed by the client concerning the essential terms and the lawyer’s role.

Suppose a lawyer offers to buy a client’s property while representing the client in a separate matter. A verbal “that’s fine” is not enough. Counsel must satisfy the rule’s fairness, disclosure, independent-counsel, opportunity, and signed-consent requirements. Even then, a transaction that is unfair or leaves the lawyer unable to represent the client competently remains impermissible.

Aggregate settlement

Rule 1.8(g) requires each client’s informed consent in a signed writing before a lawyer representing multiple clients participates in an aggregate settlement or aggregate plea arrangement. The lawyer must disclose the existence and nature of all claims or pleas and each person’s participation. Each client must be able to evaluate the individual allocation. A client’s agreement to a total settlement without the allocation details is not informed consent.

Conflict with a former client

Rule 1.9(a) permits a lawyer to represent a new client materially adverse to a former client in the same or a substantially related matter only if the former client gives informed consent confirmed in writing. The former client must understand what representation is proposed and its relationship to the earlier matter. A lawyer cannot proceed simply because the former client signed an old, broad waiver without adequate explanation of the specific conflict.

Consent is not a cure-all

Some conduct remains prohibited even if the client agrees. A lawyer cannot obtain permission to represent directly opposing clients in the same litigation under Rule 1.7(b)(3). Consent cannot make an unreasonable fee reasonable, remove the bar on contingent fees for criminal defense, excuse dishonesty to a tribunal, or permit a lawyer to assist a client’s crime or fraud. If a rule imposes a condition beyond consent, satisfy that condition too.

A client’s autonomy matters, but the lawyer retains professional responsibility for the decision. The lawyer must independently assess whether representation can be competent, whether the consent is informed, and whether the requested course complies with law and the Rules. “The client asked me to” is not a defense to a nonconsentable conflict or prohibited conduct.

Original MPRE-style applications

A generic waiver and a specific conflict

A client signed an engagement letter saying the firm may represent other clients whose interests differ. Months later, the firm is asked to sue that client in an unrelated matter. The lawyer cannot assume the general clause is informed consent to this specific direct adversity. Counsel must assess Rule 1.7 and, if the conflict is consentable, explain the material circumstances and alternatives and obtain informed consent confirmed in writing.

Shared representation of two founders

Two founders jointly retain a lawyer to negotiate a company sale. One wants a quick sale with broad warranties; the other wants a higher price and no personal indemnity. Before seeking consent, counsel explains that the clients’ goals diverge, the lawyer may not be able to advocate each position fully, and separate counsel is an alternative. If the conflict is consentable and competent and diligent representation remains reasonably possible, each can decide whether to proceed. If the lawyer cannot represent each effectively, consent does not cure the problem.

Client says nothing

A lawyer sends a client a detailed conflict email and receives no response. Silence alone is not informed consent. The lawyer should not proceed on the assumption that failure to object means agreement, especially where the rule requires informed consent confirmed in writing.

Narrow document review

A client asks a lawyer only to review a contract and expressly declines negotiation. The lawyer explains that it will identify legal risks but will not contact the counterparty, file a response, or monitor later deadlines. If that limited scope is reasonable and the client gives informed consent, Rule 1.2(c) permits it. If the contract deadline is imminent and review alone cannot protect the client’s objective, the limitation may not be reasonable without additional action.

Third-party payer

An employer offers to pay for an employee’s independent counsel but requests weekly reports on legal advice. Counsel must obtain the employee-client’s informed consent to third-party payment, protect the client’s confidential information, and refuse interference with professional judgment. If the employer insists on receiving privileged strategy without authorization, counsel cannot accept that condition.

How to analyze an informed-consent question

• Identify the proposed course and the rule that requires consent.
• Determine whether the person has enough information about material risks and reasonably available alternatives.
• Check for a separate writing requirement: confirmed in writing, signed by the client, or consent in a writing.
• Test every nonconsent condition, such as competent and diligent representation or fair transaction terms.
• Ask whether circumstances changed and whether the earlier consent covers this specific decision.
• Do not infer consent from silence or a generic advance waiver when the rule requires a particular informed decision.
