Cal. Prob. Code § 2640.1

(a) If a person has petitioned for the appointment of a particular conservator and another conservator was appointed while the petition was pending, but not before the expiration of 90 days from the issuance of letters, the person who petitioned for the appointment of a conservator but was not appointed and that person’s attorney may petition the court for an order fixing and allowing compensation and reimbursement of costs, provided that the court determines that the petition was filed in the best interests of the conservatee.
(b) Notice of the hearing shall be given for the period and in the manner provided in Chapter 3 (commencing with Section 1460) of Part 1.
(c) Upon the hearing, the court shall make an order to allow both of the following:
1. (1) Any compensation or costs requested in the petition the court determines is just and reasonable to the person who petitioned for the appointment of a conservator but was not appointed, for his or her services rendered in connection with and to facilitate the appointment of a conservator, and costs incurred in connection therewith.
2. (2) Any compensation or costs requested in the petition the court determines is just and reasonable to the attorney for that person, for his or her services rendered in connection with and to facilitate the appointment of a conservator, and costs incurred in connection therewith.
  Any compensation and costs allowed shall be charged to the estate of the conservatee. If a conservator of the estate is not appointed, but a conservator of the person is appointed, the compensation and costs allowed shall be ordered by the court to be paid from property belonging to the conservatee, whether held outright, in trust, or otherwise.
(d) It is the intent of the Legislature for this section to have retroactive effect.
