AN ATTORNEY SHOULD BE DISQUALIFIED UNDER THE ADVOCATE-WITNESS RULE WHEN THE ATTORNEY’S TESTIMONY IS NECESSARY TO PROVE ISSUES IN DISPUTE, NOT THE CASE HERE (FIRST DEPT).

The First Department, reversing (modifying) Supreme Court, determined the husband’s attorney, Smith, should not have been disqualified on the ground he would be called as a witness at trial. The appellate division determined Smith’s testimony was not relevant to the financial issues in the divorce action. Therefore Smith should not have been disqualified on the basis that his testimony would be necessary at trial:

The advocate-witness disqualification rules contained in the Code of Professional Responsibility provide guidance, but are not binding authority for courts in determining whether a party’s attorney should be disqualified during litigation … . “Disqualification of a law firm during litigation implicates not only the ethics of the profession but also the substantive rights of the litigants. Disqualification denies a party’s right to representation by the attorney of its choice” … . In considering whether to disqualify counsel, the court must consider a litigant’s right to select his own counsel and the fairness and effect of disqualification in the particular factual setting … . Whether to disqualify an attorney rests in the sound discretion of the trial court … . However, an attorney should be disqualified only when his or her testimony is necessary to prove the issues in dispute … . The party seeking or supporting disqualification need not show that counsel’s continued representation would prejudice his or her client where the court finds that counsel’s testimony is necessary on his or her client’s behalf … . De Luca v De Luca, 2025 NY Slip Op 05146, First Dept 9-25-25

Practice Point: Here the proposed testimony by the attorney was not necessary to prove issues in dispute. Therefore the attorney should not have been disqualified.
