Cal. Prob. Code § 2614.7
If a guardian or conservator of the person or estate, or both, is a professional fiduciary, as described in Section 2340, who is required to be licensed under the Professional Fiduciaries Act (Chapter 6 (commencing with Section 6500) of Division 3 of the Business and Professions Code), the guardian or conservator shall file, concurrently with the inventory and appraisal required by Section 2610, a proposed hourly fee schedule or another statement of his or her proposed compensation from the estate of the ward or conservatee for services performed as a guardian or conservator. The filing of a proposed hourly fee schedule or another statement of the guardian's or conservator's proposed compensation, as required by this section, shall not preclude a court from later reducing the guardian's, conservator's, or his or her attorney's fees or other compensation.
