N.J. Stat. Ann. § 2A:50-35

When the mortgagor or the person owning the mortgaged premises is dead at the time of the sale thereof under foreclosure, the court may, if it deems it expedient or necessary for the proper administration of the estate of the decedent, direct that the surplus arising from the proceeds of the sale be paid to the executor or administrator of the decedent, to be administered in the same manner as money arising from the sale of real estate by administrators or executors. The administrator or executor shall give bond as required by law upon an application for the sale of real estate.
