N.C. Gen. Stat. § 28A-23-5

If, after an estate has been settled and the personal representative discharged, other property of the estate shall be discovered, or if it shall appear that any necessary act remains unperformed on the part of the personal representative, or for any other proper cause, the clerk of superior court, upon the petition of any person interested in the estate and without notice or upon such notice as the clerk of superior court may direct, may order that said estate be reopened. The clerk of superior court may reappoint the personal representative or appoint another personal representative to administer such property or perform such acts as may be deemed necessary. Unless the clerk of superior court shall otherwise order, the provisions of this Chapter as to an original administration shall apply to the proceedings had in the reopened administration; but no claim which is already barred can be asserted in the reopened administration.
