N.J. Stat. § 3B:22-33
If an estate is adjudged insolvent, any creditor who fails to exhibit his claim to the personal representative within the time limited and prescribed by N.J.S. 3B:22-4 shall be forever barred from prosecuting or recovering thereon unless the estate shall prove sufficient, after all claims exhibited and allowed are fully satisfied, or the creditors shall find some other asset not accounted for by the personal representative before distribution, in which case the creditor shall receive his ratable proportion therefrom. However, the court, before distribution made, may upon the application of any creditor of any insolvent decedent and after notice to the personal representative, extend the time within which claims may be presented by creditors of the decedent upon terms as the court may deem just.
