N.J. Stat. § 2A:31-6
When an action is commenced by an administrator ad prosequendum under this chapter, no payment in settlement thereof or in satisfaction of a judgment rendered therein shall be made to him, but such payment shall be made only to the duly appointed general administrator of the estate of the decedent, who has filed a bond or supplemental bond adequate to protect the persons entitled to receive the amount so paid.
No release or cancellation of a judgment, whether by warrant or otherwise, by an administrator ad prosequendum or by his attorney of record or attorney in fact shall release the person making payment from liability to the persons entitled to any intestate personal property of the decedent, shall operate as a valid cancellation of the judgment or be an authority to the clerk of any court to cancel the judgment of record.
