N.J. Stat. § 2A:17-64
If it is made to appear that the judgment debtor is entitled to, or is in receipt of, an income or any property or money or things in action, or rights and credits, including such income as is derived from federal, state, county, municipal or other governmental sources, but not income or property as is recovered or exempt by law, the Superior Court may direct the judgment debtor to make payments at stated periods in installments, and upon such terms and conditions as the court may direct, out of the same, on account of the unsatisfied judgment. Application may be made at any time on behalf of the judgment creditor, his executor, administrator or assignee, or the judgment debtor, to modify the terms of such order, and the court may make such modification.
