Model Rule 4.3: Dealing with Unrepresented Person

Rule 4.3 governs how a lawyer must behave when dealing on behalf of a client with someone who isn't represented by counsel. The lawyer must not let the unrepresented person mistakenly believe the lawyer is disinterested or neutral, and must correct that impression if it becomes clear the person misunderstands the lawyer's role. If the unrepresented person's interests could conflict with the client's, the lawyer's ability to give legal advice to that person (other than the advice to get counsel) is sharply limited.

When it applies

This comes up whenever a lawyer negotiates, interviews, or communicates with an opposing party, witness, or third party who has no lawyer—common in settlement talks, witness interviews, and transactional dealings. MPRE questions test whether the lawyer clarified their role and avoided giving substantive advice to the unrepresented person.

What the rule requires

  • The lawyer must not state or imply that they are disinterested or neutral when dealing with an unrepresented person.
  • If the lawyer knows or reasonably should know the unrepresented person misunderstands the lawyer's role, the lawyer must make reasonable efforts to correct that misunderstanding.
  • When the unrepresented person's interests may conflict with the client's, the lawyer shall not give legal advice other than the advice to secure counsel.
  • The lawyer may still explain basic facts about the legal matter and the process, as long as this doesn't cross into advising on the person's legal rights or strategy.
  • The lawyer should identify themselves and who they represent so the unrepresented person understands the adversarial or transactional context.

Exceptions

  • The rule's advice restriction applies when the lawyer knows or reasonably should know that the unrepresented person's interests are in conflict with the client's, or have a reasonable possibility of being in conflict; if there is no reasonable possibility of conflict, more latitude exists.
  • A lawyer may still provide neutral procedural information (e.g., how a process works) without violating the advice limitation.

How the MPRE tests Model Rule 4.3

  • Students confuse this with Rule 4.1 (truthfulness to third persons); 4.3 is about role clarity and advice limits, not just avoiding false statements.
  • MPRE questions test whether merely failing to volunteer that you represent the other side violates the rule—silence alone about representation is fine unless it creates a false impression of neutrality.
  • Test-takers often think any communication with an unrepresented person is barred; the rule permits communication, just restricts giving legal advice when interests conflict.
  • Watch for fact patterns where the lawyer gives seemingly 'helpful' advice (e.g., 'you should sign this now') to an unrepresented opposing party—this violates the rule if interests diverge.

Example

A lawyer representing an insurance company calls an unrepresented accident victim to negotiate a settlement and tells her, 'You don't need a lawyer, just sign this release, it's a standard formality.' Because the victim's interests conflict with the insurer's, the lawyer violated Rule 4.3 by giving advice beyond suggesting she obtain counsel, and by potentially creating a false impression of disinterested helpfulness.
