California Code, Probate Code - PROB § 1853

(a) If the court investigator is unable to locate the conservatee, the court shall order the court investigator to serve notice upon the conservator of the person, or upon the conservator of the estate if there is no conservator of the person, in the manner provided in Section 415.10 or 415.30 of the Code of Civil Procedure or in such other manner as is ordered by the court, to make the conservatee available for the purposes of Section 1851 to the court investigator within 15 days of the receipt of such notice or to show cause why the conservatorship should not be terminated.

(b) If the conservatee is not made available within the time prescribed, unless good cause is shown for not doing so, the court shall make such a finding and shall enter judgment terminating the conservatorship and, in case of a conservatorship of the estate, shall order the conservator to file an account and to surrender the estate to the person legally entitled thereto. At the hearing, or thereafter on further notice and hearing, the conservator may be discharged and the bond given by the conservator may be exonerated upon the settlement and approval of the conservator's final account by the court.

(c) Termination of the conservatorship under this section does not preclude institution of new proceedings for the appointment of a conservator. Nothing in this section limits the power of a court to appoint a temporary conservator under Chapter 3 (commencing with Section 2250) of Part 4.
