§ 310. Authentication of acknowledgments and proofs made within the
state. 1. When a certificate of acknowledgment or proof is made, within
this state, by a commissioner of deeds, a justice of the peace, town
council member, village police justice, or a judge of any court of
inferior local jurisdiction, such certificate does not entitle the
conveyance so acknowledged or proved to be read in evidence or recorded
in any county of this state except a county in which the officer making
such certificate is authorized to act at the time of making the same,
unless such certificate is authenticated by a certificate of the clerk
of such county; provided, however, that all certificates of
acknowledgment or proof, made by a commissioner of deeds of the city of
New York residing in any part therein, shall be authenticated by the
clerk of any county within said city, in whose office such commissioner
of deeds shall have filed a certificate under the hand and seal of the
city clerk of said city, showing the appointment and term of office of
such commissioner; and no other certificates shall be required from any
other officer to entitle such conveyance to be read in evidence or
recorded in any county of this state.

2. Except as provided in this section, no certificate of
authentication shall be required to entitle a conveyance to be read in
evidence or recorded in this state when acknowledged or proved before
any officer designated in section two hundred ninety-eight of this
article to take such acknowledgment or proof, nor shall such
authentication be required for recording in the office of the city
register of the city of New York of such acknowledgment or proof by a
commissioner of deeds of the city of New York.
