N.J. Stat. § 2A:17-81
An execution creditor, his executor or administrator, may, when an execution debtor dies after execution has been issued against his person, but before the judgment under which it issued has been satisfied, have new execution against the goods and chattels and real estate of the execution debtor which he might have had if such debtor had not died.
Under the new execution, no real estate of such execution debtor shall be sold, which, at any time after the judgment against such debtor under which the original execution issued, has been sold by him, bona fide, and of which the proceeds of the sale have been either paid or secured to be paid to any of his creditors, with their privity or consent, in discharge of his debts, or some part thereof. Nor shall there be sold under such execution any real estate of the deceased debtor, which shall have been sold by reason of any other judgment against him.
