No instrument authorizing a fiduciary whom it names to serve without bond shall be construed to relieve a successor fiduciary from the necessity of giving bond, unless the instrument clearly evidences that intention.
The court that appoints a fiduciary may reduce the amount of the bond of the fiduciary at any time for good cause shown.
When two or more persons are appointed as joint fiduciaries, the court may take a separate bond from each or a joint bond from all.
