New York Consolidated Laws, Uniform District Court Act - UDC § 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.
