2006 New York Code - Subpoenas.

 
  § 1201. Subpoenas.
    A  subpoena  and  a  subpoena duces tecum, and the powers of the court
  with reference to them, shall be governed by the CPLR, except that  they
  shall  be  served  only  within  the county or in a county adjoining the
  county in which the action is pending or within the city of New York  if
  the  action  is  pending in a county adjoining such city. But the court,
  upon motion of a party which need not be on  notice,  may  issue  either
  kind  of subpoena and permit its service elsewhere outside the county if
  satisfied that the interests of justice would be served thereby.
