(a) Unless prohibited by order of the court and except for estates being administered in supervised administration proceedings, a personal representative may close an estate by filing with the court no earlier than six months after the date of original appointment of a general personal representative for the estate, a verified statement stating that the personal representative, or a prior personal representative, has

(1) published notice to creditors as provided by AS 13.16.450 and that the first publication occurred more than six months before the date of the statement;

(2) fully administered the estate of the decedent by making payment, settlement, or other disposition of all claims that were presented, expenses of administration and estate, inheritance, and other death taxes, except as specified in the statement, and that the assets of the estate have been distributed to the persons entitled; if any claims remain undischarged, the statement must state whether the personal representative has distributed the estate subject to possible liability with the agreement of the distributees or it must state in detail other arrangements that have been made to accommodate outstanding liabilities; and

(3) sent a copy of it to all distributees of the estate and to all creditors or other claimants of whom the personal representative is aware whose claims are neither paid nor barred and has furnished a full account in writing of the administration to the distributees whose interests are affected by it.

(b) If no proceedings involving the personal representative are pending in the court one year after the closing statement is filed, the appointment of the personal representative terminates.
