N.Y. Real Property Law § 304: Proof by subscribing witness

§ 304. Proof by subscribing witness. When the execution of a

conveyance is proved by a subscribing witness, such witness must state

his own place of residence, and if his place of residence is in a city,

the street and street number, if any thereof, and that he knew the

person described in and who executed the conveyance. The proof must not

be taken unless the officer is personally acquainted with such witness,

or has satisfactory evidence that he is the same person, who was a

subscribing witness to the conveyance.
