R.I. Gen. Laws § 33-11-45: Claim barred by failure to prove or prosecute.

If a claimant shall not request probate court determination of its disallowed claim or bring civil action on its disallowed claim within the deadlines of this chapter, any action on said claim against the personal representative and estate of the decedent shall be forever barred. Affidavit of the personal representative or certificate of the district or superior court clerk that no civil action was brought by the claimant in the relevant time period shall be sufficient to establish failure to timely prosecute.
