CA Prob Code Section 9614

(a)

On petition of an interested person, the court may suspend the powers of the personal representative in whole or in part, for a time, as to specific property or circumstances or as to specific duties of the office, or may make any other order to secure proper performance of the duties of the personal representative, if it appears to the court that the personal representative otherwise may take some action that would jeopardize unreasonably the interest of the petitioner. Persons with whom the personal representative may transact business may be made parties.

(b)

The matter shall be set for hearing within 10 days unless the parties agree otherwise. Notice as the court directs shall be given to the personal representative and attorney of record, if any, and to any other parties named in the petition.

(c)

The court may, in its discretion, if it determines that the petition was brought unreasonably and for the purpose of hindering the personal representative in the performance of the duties of the office, assess attorney’s fees against the petitioner and make the assessment a charge against the interest of the petitioner.
