Rule 3.7 Lawyer as Witness

Advocate

(a) A lawyer shall not act as advocate at a trial in which the lawyer is likely to be a necessary witness unless:

(1) the testimony relates to an uncontested issue;

(2) the testimony relates to the nature and value of legal services rendered in the case; or

(3) disqualification of the lawyer would work substantial hardship on the client.

(b) A lawyer may act as advocate in a trial in which another lawyer in the lawyer’s firm is likely to be called as a witness unless precluded from doing so by Rule 1.7 or Rule 1.9.

Absent proof prosecutor “necessary” witness, no disqualification. — The defendant did not demonstrate that the assistant district attorney would be a “necessary” witness and, therefore, the assistant district attorney was not required to disqualify himself from prosecuting the case under this rule. Rudolph v. State, 829 P.2d 269, 1992 Wyo. LEXIS 40 (Wyo. 1992). Attorney as necessary witness. — Where drugs were found during search of vehicle stopped for faulty taillight, attorney could not represent defendant and also testify that taillight was not defective, since this rendered attorney a necessary witness. Mora v. State, 984 P.2d 477, 1999 Wyo. LEXIS 124 (Wyo. 1999). Attorney who was sole shareholder of corporation not allowed to testify. — This rule requires a balancing between the interests of the parties in the proceeding in all situations except where the testimony concerns uncontested issues or the value of legal services, and the district court did not abuse its discretion when it did not allow corporation’s attorney, its sole shareholder, to testify at bench trial.
