New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 50-65

Any judgment creditor shall, upon entry of judgment in the office of the Clerk of the Superior Court, provide the Court with its current address for service. If the judgment creditor's address for service changes, it shall be incumbent upon the judgment creditor to effect a change of address for service by filing an appropriate form with the court in a timely manner. If any judgment creditor fails to provide the Court with a current or change of address for service, in any foreclosure proceeding, the plaintiff may, without having to first make a more diligent inquiry or publish notice in a newspaper, serve the judgment creditor by ordinary mail and certified mail at the address that is reflected in the records of the Clerk of the Superior Court. The judgment creditor shall, if known, provide the Clerk of the Court with the judgment debtor's social security number or taxpayer identification number.
