Rules of Professional Conduct
Rule 5-210 Member as Witness
A member shall not act as an advocate before a jury which will hear testimony from the member unless:
(A) The testimony relates to an uncontested matter; or
(B) The testimony relates to the nature and value of legal services rendered in the case; or
(C) The member has the informed, written consent of the client. If the member represents the People or a governmental entity, the consent shall be obtained from the head of the office or a designee of the head of the office by which the member is employed and shall be consistent with principles of recusal.
Rule 5-210 is intended to apply to situations in which the member knows or should know that he or she ought to be called as a witness in litigation in which there is a jury. This rule is not intended to encompass situations in which the member is representing the client in an adversarial proceeding and is testifying before a judge. In non-adversarial proceedings, as where the member testifies on behalf of the client in a hearing before a legislative body, rule 5-210 is not applicable.
Rule 5-210 is not intended to apply to circumstances in which a lawyer in an advocate's firm will be a witness. (Amended by order of Supreme Court, operative September 14, 1992.)
