Cal. Family Code § 1839

(a) At or after the hearing, the court may make orders in respect to the conduct of the spouses or parents and the subject matter of the controversy that the court deems necessary to preserve the marriage or to implement the reconciliation of the spouses. No such order shall be effective for more than 30 days from the hearing of the petition unless the parties mutually consent to a continuation of the time the order remains effective. (b) A reconciliation agreement between the parties may be reduced to writing and, with the consent of the parties, a court order may be made requiring the parties to comply fully with the agreement. (c) During the pendency of a proceeding under this part, the superior court may order a spouse or parent, as the case may be, to pay an amount necessary for the support and maintenance of the other spouse and for the support, maintenance, and education of the minor children, as the case may be. In determining the amount, the superior court may take into consideration the recommendations of a financial referee if one is available to the court. An order made pursuant to this subdivision shall not prejudice the rights of the parties or children with respect to any subsequent order that may be made. An order made pursuant to this subdivision may be modified or terminated at any time except as to an amount that accrued before the date of filing of the notice of motion or order to show cause to modify or terminate.
