Ordered that the appeal is dismissed, without costs or disbursements.
The authority of the Family Court to appoint a guardian extends only to the person or property of a "minor," which is defined as a person under the age of 18 (Family Ct Act § 119 [c]; § 661). Moreover, "[a]s a general rule, the appointment of a guardian for a minor expires when the subject child reaches the age of majority" ( Matter of Luis A.S., 33 AD3d 793, 794; see SCPA 1707; Family Ct Act § 661; Matter of Mede, 177 Misc 2d 974, 979-980). Because the appellant has reached the age of 18, this appeal has been rendered academic and must be dismissed, since the appointment by the Family Court of a guardian for the appellant has expired, and there is no basis upon which the relief requested can be granted ( see Matter of Luis A.S., supra at 794). [ See 13 Misc 3d 180 (2006).]
