Upon the filing of a supplemental report of distribution together with receipts or other evidence satisfactory to the court that distribution has been made as ordered in the final decree, the court shall enter an order of discharge. The discharge so obtained shall operate as a release from the duties of personal representative and shall operate as a bar to any suit including suits by persons under disability, against the personal representative and his sureties except suits which are commenced within one (1) year from the date of the discharge and are based solely upon alleged mistake, fraud or wilful misconduct on the part of the personal representative.
