When a lawyer is a witness for his client, except as to merely formal matters, such as the attestation or custody of an instrument and the like, he should leave the trial of the case to other counsel. Except when essential to the ends of justice, a lawyer should avoid testifying in court in behalf of his client.Google Scholar

12 The following is the full text of EC 5-9:Google Scholar

Occasionally a lawyer is called upon to decide in a particular case whether he will be a witness or an advocate. If a lawyer is both counsel and witness he becomes more easily impeachable for interest and thus may be a less effective witness. Conversely, the opposing counsel may be handicapped in challenging the credibility of the lawyer when the lawyer also appears as an advocate in the case. An advocate who becomes a witness is in the unseemly and ineffective position of arguing his own credibility. The roles of an advocate and of a witness are inconsistent; the function of an advocate is to advance or argue the cause of another, while that of a witness is to state facts objectively.Google Scholar

13 See also John F. Sutton, Jr., The Testifying Advocate, 41 Tex. L. Rev. 477, 482-83 (1963), which also suggests that fairness to the client requires that the lawyer not make himself subject to impeachment by accepting the case. This should be distinguished from the early practice of disqualifying the lawyer as a witness for interest. 6 John Henry Wigmore, Evidence 596-97 (3d ed. 1940). There, the lawyer could not appear as a witness. Under the rule of ethics the lawyer's testimony is competent but he is required to give up the representation. See note 30 infra.
