(a) As to claims presented in the manner described in section 1204 of this title within the time limit prescribed in section 1203 of this title, the executor or administrator shall, if a claim is disallowed, mail a notice to any claimant stating that the claim has been disallowed. If, after allowing or disallowing a claim, the executor or administrator changes his or her decision concerning the claim, he or she shall notify the claimant. The executor or administrator 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 which is disallowed in whole or in part by the executor or administrator is barred so far as not allowed unless the claimant files a petition for allowance in the court or commences a proceeding against the executor or administrator 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 executor or administrator to mail notice to a claimant of action on his claim for 60 days after the time for original presentation of the claim not otherwise barred has expired shall have the effect of allowance.

(b) Upon motion of the executor or administrator or petition of a claimant, the Probate Division of the Superior Court may allow in whole or in part any claim or claims timely presented. Notice in this proceeding shall be given as provided by the Rules of Probate Procedure.

(c) A judgment in a proceeding in another court against an executor or administrator to enforce a claim against a decedent's estate is an allowance of the claim.

(d) By agreement between a claimant and the executor or administrator, a claim may be referred to one or more arbitrators, chosen either by the claimant and the executor or administrator, or, if they so request, by the Probate Division of the Superior Court. The decision of the arbitrator shall be final and binding.

(e) Unless otherwise provided in any judgment in another court entered against the executor or administrator, allowed claims bear interest at the legal rate for the period commencing 60 days after the time for original presentation of claim has expired unless based on a contract making a provision for interest, in which case they bear interest in accordance with that provision.
