CPLR § 2304

§ 2304. Motion to quash, fix conditions or modify. A motion to quash, fix conditions or modify a subpoena shall be made promptly in the court in which the subpoena is returnable. If the subpoena is not returnable in a court, a request to withdraw or modify the subpoena shall first be made to the person who issued it and a motion to quash, fix conditions or modify may thereafter be made in the supreme court; except that such motion with respect to a child support subpoena issued pursuant to section one hundred eleven-p of the social services law shall be made to a judge of the family court or the supreme court. Reasonable conditions may be imposed upon the granting or denial of a motion to quash or modify.
