New York Consolidated Laws, Civil Practice Law and Rules - CVP § 2212. Where motion made, in supreme court action

(a) Motions on notice.  A motion on notice in an action in the supreme court shall be noticed to be heard in the judicial district where the action is triable or in a county adjoining the county where the action is triable.  Unless statute, civil practice rule or local court rule provides otherwise, the motion shall be noticed to be heard before a motion term or, upon order to show cause granted by a justice, before that justice out of court.

(b) Ex parte motions.  A motion in an action in the supreme court that may be made without notice may be made at a motion term or to a justice out of court in any county in the state.

(c) Motions before a county court or judge.  The chief administrator of the courts may by rule provide for the hearing of motions on notice or ex parte motions in an action or proceeding in the supreme court by a term of the county court or a county judge in the county in which venue is laid during periods in which no supreme court trial or special term is in session in the county.

(d) Rules of the chief administrator of the courts.  The chief administrator may by rule exclude motions within a department, district or county from the operation of subdivisions (a), (b) and (c) of this section, provided, however, that the practice in counties within the city of New York shall be uniform.
