When additional or new bond may be required of a fiduciary, or his authority be revoked

The county commission under whose order, or under the order of whose clerk, any such fiduciary derives his authority, when it appears proper on any report of the clerk or a fiduciary commissioner or a commissioner in chancery, or on evidence adduced before it by any party interested, may, at any time, whether such fiduciary shall or shall not have before given any bond, or whether he shall have given one with or without sureties, order him to give before the commission an additional bond within a prescribed reasonable time, in such penalty, and with or without sureties, as may appear proper; or when any surety on the bond of a fiduciary, or the personal representative of any surety, shall apply therefor, the commission shall order the fiduciary to give before it a new bond within a prescribed reasonable time, in such penalty, and with such sureties, as may appear proper, it may, in either case, if the order be not complied with, or whenever from any cause it appears proper, revoke and annul the powers of such fiduciary. No such order shall be made unless reasonable notice is given to the fiduciary by the clerk or the fiduciary commissioner who made the report, or by the surety or the personal representative of the surety making the application aforesaid, or by the service of a rule or otherwise. No such order of revocation shall invalidate any previous acts of the fiduciary.
