N.Y. Real Property Actions & Proceedings Law § 1513: Guardians ad litem

§ 1513. Guardians ad litem. If it shall appear by the complaint or is

otherwise made to appear to the court at any time before a final

judgment, that a defendant is or might be an infant, or incompetent to

manage himself or his affairs, or that a future interest in the affected

real property has been so limited that as yet there are neither certain

nor presumptive owners thereof in being or ascertained, such court shall

appoint a guardian ad litem who shall represent and protect such infant

or incompetent, or the possible interests of the person or persons who

eventually may become entitled to such real property or to an interest

therein under such limitation, and in case of the death or failure or

inability of such guardian to act, a successor, who shall appear for

such infant or incompetent or for such possible interests until the

termination of such action.
