§ 133. Certification  of  notarial  signatures.  The county clerk of a
  county in whose office any notary public has qualified or has filed  his
  autograph  signature and a certificate of his official character, shall,
  when so requested and upon payment of a fee of fifty cents affix to  any
  certificate  of  proof  or  acknowledgment or oath signed by such notary
  anywhere in the state or New York, a  certificate  under  his  hand  and
  seal,  stating  that  a  commission  or  a  certificate  of his official
  character with his autograph signature has been filed in his office, and
  that he was at the time of taking such proof or acknowledgment  or  oath
  duly  authorized  to  take the same; that he is well acquainted with the
  handwriting of such notary public or has compared the signature  on  the
  certificate  of  proof  or  acknowledgment  or  oath  with the autograph
  signature deposited in his office by such  notary  public  and  believes
  that  the  signature is genuine.  An instrument with such certificate of
  authentication of the county clerk affixed thereto shall be entitled  to
  be  read  in  evidence  or to be recorded in any of the counties of this
  state in respect to which  a  certificate  of  a  county  clerk  may  be
  necessary for either purpose.
