N.J. Stat. § 2A:82-17
If any instrument heretofore made and executed or hereafter to be made and executed shall have been acknowledged, by any party who shall have executed it, or the execution thereof by such party shall have been proved by one or more of the subscribing witnesses to such instrument, in the manner and before one of the officers provided and required by law for the acknowledgment or proof of instruments in order to entitle them to be recorded, and, when a certificate of such acknowledgment or proof shall be written upon or under, or be annexed to such instrument and signed by such officer in the manner prescribed by law, such certificate of acknowledgment or proof 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.
