(a) Accountings Required by Statute. When any personal representative or guardian fails to file an accounting or return required by statute or rule, the court on its own motion or on the petition of an interested person shall order the personal representative or guardian to file the accounting or return within 15 days from the service on the personal representative or guardian of the order, or show cause why he or she should not be compelled to do so.
(b) Accountings Not Required by Statute. On the petition of an interested person, or on its own motion, the court may require the personal representative or guardian to file an accounting or return not otherwise required by statute or rule. The order requiring an accounting or return shall order the personal representative or guardian to file the accounting or return within a specified time from service on the personal representative or guardian of the order, or show cause why he or she should not be compelled to do so.
(c) Service. A copy of the order shall be served on the personal representative or guardian and the personal representative’s or guardian’s attorney.
