California Code, Probate Code - PROB § 2640

(a) At any time after the filing of the inventory and appraisal, but not before the expiration of 90 days from the issuance of letters or any other period of time as the court for good cause orders, the guardian or conservator of the estate may petition the court for an order fixing and allowing compensation to any one or more of the following:

(b) Notice of the hearing shall be given for the period and in the manner provided for in Chapter 3 (commencing with Section 1460) of Part 1.

(c) Upon the hearing, the court shall make an order allowing (1) any compensation requested in the petition the court determines is just and reasonable to the guardian or conservator of the estate for services rendered or to the guardian or conservator of the person for services rendered, or to both, and (2) any compensation requested in the petition the court determines is reasonable to the attorney for services rendered to the guardian or conservator of the person or estate or both. The compensation allowed to the guardian or conservator of the person, the guardian or conservator of the estate, and to the attorney may, in the discretion of the court, include compensation for services rendered before the date of the order appointing the guardian or conservator. The compensation allowed shall be charged to the estate. Legal services for which the attorney may be compensated include those services rendered by any paralegal performing legal services under the direction and supervision of an attorney. The petition or application for compensation shall set forth the hours spent and services performed by the paralegal.

(e) Notwithstanding subdivision (c), the guardian, conservator, or attorney shall not be compensated with any government benefits program moneys unless deemed by the court as necessary to sustain the support and maintenance of the ward or conservatee, but in no event may this exceed the amount permitted by federal laws and regulations.
