R.I. Gen. Laws § 33-18-27
If an executor, administrator, or guardian has paid or delivered to the persons entitled thereto the money or other property in his or her hands as required by a decree of a probate court, he or she may perpetuate the evidence of payment or delivery by presenting to the court, within one year after the decree is made, an account of the payments or delivery, together with the vouchers therefor, which shall be kept in the files of the court. The account, being proved to the satisfaction of the court, and verified by the oath of the executor, administrator, or guardian, shall be allowed as his or her final discharge and ordered to be recorded. This discharge shall forever exonerate the executor, administrator, or guardian, and his or her sureties, from all liability under the decree unless his or her account is impeached for fraud or manifest errors.
