Rule 16-307. Lawyer as witness.

A. Necessary witnesses. 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. Associate lawyer. 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 16-107 NMRA or Rule 16-109 NMRA of the Rules of Professional Conduct.
