137 - Statement as to Authority of Notaries Public.

§ 137. Statement as to authority of notaries public. In exercising his
  powers  pursuant  to  this  article, a notary public, in addition to the
  venue of his act and his signature, shall  print,  typewrite,  or  stamp
  beneath  his  signature in black ink, his name, the words "Notary Public
  State of New York," the name  of  the  county  in  which  he  originally
  qualified,  and  the  date  upon  which  his  commission expires and, in
  addition, wherever required, a notary public shall also include the name
  of any county in which his certificate of official character  is  filed,
  using  the  words "Certificate filed .......... County." A notary public
  who is duly licensed as an attorney and counsellor at law in this  state
  may  in his discretion, substitute the words "Attorney and Counsellor at
  Law" for the words "Notary Public." A notary public who has qualified or
  who has filed a certificate of official character in the office  of  the
  clerk  in  a  county  or  counties within the city of New York must also
  affix to each instrument his official number or numbers in black ink, as
  given to him by the clerk or clerks of such county or  counties  at  the
  time  such  notary  qualified  in  such  county  or counties and, if the
  instrument is to be recorded in an office of the register of the city of
  New York in any county within such city and the notary has been given  a
  number  or numbers by such register or his predecessors in any county or
  counties, when his autographed signature and certificate  are  filed  in
  such  office  or  offices  pursuant to this chapter, he shall also affix
  such number or numbers. No official act of such notary public  shall  be
  held  invalid on account of the failure to comply with these provisions.
  If any notary public shall wilfully fail  to  comply  with  any  of  the
  provisions  of  this section, he shall be subject to disciplinary action
  by the secretary of state. In all  the  courts  within  this  state  the
  certificate of a notary public, over his signature, shall be received as
  presumptive  evidence  of  the  facts  contained  in  such  certificate;
  provided,  that  any  person  interested  as  a  party  to  a  suit  may
  contradict, by other evidence, the certificate of a notary public.
