CA Prob Code Section 2334

Where a petition is filed requesting an order that a guardian or conservator be required to give a bond where no bond was originally required, or an objection is made to the sufficiency of the bond, and the petition or affidavit supporting the objection alleges facts showing that the guardian or conservator is failing to use ordinary care and diligence in the management of the estate, the court, by order, may suspend the powers of the guardian or conservator until the matter can be heard and determined.
