The court, on its own motion or upon application of any interested person, may for good cause require a fiduciary to file a new or additional bond. Thereupon the fiduciary’s accounts shall be settled, and if approved the liability of the sureties on such new or additional bond shall be limited to the property then in the possession of the fiduciary, or thereafter acquired by him or her. Whenever the court shall find the bond of a fiduciary is larger than necessary, it may, by order, reduce the liability thereon to the proper amount. It may, by like order, cancel any bond found to be unnecessary.
