California Probate Code
(a) On or after the filing of a petition for appointment of a conservator, any person entitled to petition for appointment of the conservator may file a petition for appointment of a temporary conservator of the person or estate or both.
(b) The petition shall state facts that establish good cause for appointment of the temporary conservator. The court, upon that petition or any other showing as it may require, may appoint a temporary conservator of the person or estate or both, to serve pending the final determination of the court upon the petition for the appointment of the conservator.
(c) Unless the court for good cause otherwise orders, not less than five days before the appointment of the temporary conservator, notice of the proposed appointment shall be personally delivered to the proposed conservatee.
(d) If the court suspends powers of the conservator under Section 2334 or 2654 or under any other provision of this division, the court may appoint a temporary conservator to exercise those powers until the powers are restored to the conservator or a new conservator is appointed.
(e) If for any reason a vacancy occurs in the office of conservator, the court, on a petition filed under subdivision (a) or on its own motion, may appoint a temporary conservator to exercise the powers of the conservator until a new conservator is appointed.
(f) This section shall only apply to proceedings under Chapter 3 (commencing with Section 5350) of Part 1 of Division 5 of the Welfare and Institutions Code.
