(a) As to claims presented in the manner described in AS 13.16.465 within the time limit prescribed in AS 13.16.460, the personal representative may mail a notice to any claimant stating that the claim has been disallowed. If, after allowing or disallowing a claim, the personal representative changes a decision concerning the claim, the personal representative shall notify the claimant. The personal representative may not change a disallowance of a claim after the time for the claimant to file a petition for allowance or to commence a proceeding on the claim has run and the claim has been barred. Every claim that is disallowed in whole or in part by the personal representative is barred so far as not allowed unless the claimant files a petition for allowance in the court or commences a proceeding against the personal representative not later than 60 days after the mailing of the notice of disallowance or partial allowance if the notice warns the claimant of the impending bar. Failure of the personal representative to mail to a claimant notice of action on a claim for 60 days after the time for original presentation of the claim has expired has the effect of a notice of allowance.
(b) Upon the petition of the personal representative or of a claimant in a proceeding for the purpose, the court may allow in whole or in part any claim or claims presented to the personal representative or filed with the clerk of the court in due time and not barred by (a) of this section. Notice in this proceeding shall be given to the claimant, the personal representative, and those other persons interested in the estate as the court may direct by order entered at the time the proceeding is commenced.
(c) A judgment in a proceeding in another court against a personal representative to enforce a claim against a decedent's estate is an allowance of the claim.
(d) Unless otherwise provided in any judgment in another court entered against the personal representative, allowed claims bear interest at the legal rate for the period commencing 60 days after the time for original presentation of the claim has expired unless based on a contract making a provision for interest, in which case they bear interest in accordance with that provision.
