New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 24-5

If a method is provided in the agreement for naming or appointing an arbitrator or an umpire, it shall be followed; but if not so provided, or if one is provided and a party thereto shall fail to avail himself thereof, or for other reasons there shall be a lapse or failure in the naming of an arbitrator or an umpire or in filling a vacancy, the Superior Court may in the summary action provided for in N.J.S.2A:24-3 or in another action, designate and appoint an arbitrator or an umpire, as the case may require, who shall act thereunder with the same force and effect as if specifically named therein. The arbitration shall be by a single arbitrator unless otherwise provided.
