N.J. Stat. § 2A:82-18
If any instrument heretofore made and executed or hereafter to be made and executed, although not acknowledged or proved, shall have been certified or authenticated, as to the execution thereof by any party thereto, in any manner which may be prescribed by law in order to entitle such instrument to be recorded in any public office of this state without a certificate of acknowledgment or proof thereof, such certification or authentication shall be and constitute prima facie evidence of the due execution of such instrument by such party. Such instrument shall be received in evidence in any court or proceeding in this state, in the same manner and to the same effect as though the execution of such instrument by such party had been proved by other evidence.
