2006 New York Code - 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.
