N.C. Gen. Stat. § 28A-21-1
Until the final account has been filed pursuant to G.S. 28A-21-2, the personal representative or collector shall, for so long as any of the property of the estate remains in the control, custody or possession of the personal representative or collector, file annually in the office of the clerk of superior court an inventory and account, under oath, of the amount of property received by the personal representative or collector, or invested by the personal representative or collector, and the manner and nature of such investment, and the receipts and disbursements of the personal representative or collector for the past year. Such accounts shall be due 30 days after the expiration of one year from the date of qualification of the personal representative or collector, or if a fiscal year is selected by the fifteenth day of the fourth month after the close of the fiscal year selected by the personal representative or collector, and annually on the same date thereafter. The election of a fiscal year shall be made by the personal representative or collector upon filing of the first annual account. In no event may a personal representative or collector select a fiscal year-end which is more than twelve months from the date of death of the decedent or, in the case of trust administration, the date of the opening of the trust. Any fiscal year selected may not be changed without the permission of the clerk of superior court.
The personal representative or collector shall produce vouchers for all payments or verified proof for payments in lieu of vouchers. The clerk of superior court may examine, under oath, such accounting party, or any other person, concerning the receipts, disbursements or any other matter relating to the estate. The clerk of superior court must carefully review and audit such account and, if the clerk approves the account, the clerk must endorse the approval of the clerk thereon, which shall be prima facie evidence of correctness, and cause the same to be recorded.
