N.Y. Real Prop. Law § 370
Real property, or any estate, interest, or right therein, the title to which is hereby authorized to be registered, may be brought under the operation of this article by the filing of a verified petition praying for registration, with the clerk of the county in which the land, or some portion thereof, is situated. The petition may be so made in person by the owner or owners of such property, estate, interest, or right, or, where special circumstances are shown making it impracticable for the owner to make such petition in person, by an agent acting under a power of attorney acknowledged in the same manner as a deed to be recorded. A corporation may also apply by its duly authorized officer or agent. An infant or other person under disability may apply by his legally appointed guardian, trustee, committee or conservator. The natural person or corporation, in whose behalf the petition is filed may be known, and is treated in this article, as the petitioner. Any other party to the proceeding may be known as a defendant.
