Model Rule 4.1: Truthfulness in Statements to Others
Rule 4.1 requires that in the course of representing a client, a lawyer not knowingly make a false statement of material fact or law to a third person. It also requires disclosure of a material fact to a third person when necessary to avoid assisting a client's crime or fraud, unless Rule 1.6 prohibits that disclosure. If one of Rule 1.6's exceptions permits the disclosure, Rule 4.1(b) makes it mandatory.
When it applies
This comes up in negotiations, settlement discussions, and dealings with opposing counsel, witnesses, or other third parties while representing a client. On the MPRE, it's tested through fact patterns involving negotiation "puffing," misrepresentations to opposing counsel, or a lawyer's silence when a client is defrauding someone.
What the rule requires
- A lawyer shall not knowingly make a false statement of material fact or law to a third person while representing a client.
- The prohibition applies only to statements the lawyer knows are false, not merely mistaken or careless ones.
- A lawyer must disclose a material fact to a third person when necessary to avoid assisting a client's criminal or fraudulent act.
- The duty to disclose applies only when Rule 1.6 does not prohibit the disclosure. If the information is confidential and no Rule 1.6 exception permits disclosure, the lawyer need not disclose, though withdrawal under Rule 1.16 may be required or permitted. If a Rule 1.6 exception permits disclosure, such as the crime/fraud exceptions in 1.6(b)(2)-(3), the lawyer must disclose.
- Statements of material fact or law include factual assertions but exclude certain accepted conventions in negotiation.
Exceptions
- Estimates of value, opinions on settlement position, and a party's intentions regarding acceptable settlement terms are generally treated as non-actionable "puffing," not statements of material fact.
- If Rule 1.6 prohibits the disclosure, the lawyer is not required to disclose under 4.1(b). This exception does not apply where a Rule 1.6 exception permits the disclosure.
How the MPRE tests Model Rule 4.1
- Students forget that 4.1 only covers "knowing" falsity—negligent or unknowing misstatements don't violate the rule.
- Confusing puffing/negotiation rhetoric (permissible) with actual false statements of fact (prohibited).
- Overlooking how 4.1(b) interacts with 1.6. Silence is permitted amid client fraud only if 1.6 prohibits disclosure. If a 1.6 exception (such as the crime/fraud exceptions) permits disclosure, 4.1(b) converts that permission into a duty to disclose.
- Mixing up 4.1 (duties to third persons) with 3.3 (duties of candor to a tribunal), which has different and often stricter disclosure obligations.
Example
During settlement talks, a lawyer tells opposing counsel that her client "won't take less than $50,000" when in fact the client authorized her to accept $30,000. This is permissible because statements about acceptable settlement terms are treated as negotiation puffery, not statements of material fact. However, if the lawyer instead knowingly told opposing counsel that her client had no other insurance policy when she knew one existed, that would violate Rule 4.1 as a knowing false statement of material fact.
