Cal. Gov't Code § 77212
(d)
(1) If a trial court desires to receive or continue to receive a specific service from a county or city and county as provided in subdivision (c), and the county or city and county desires to provide or continue to provide that service as provided in subdivision (b), the presiding judge of that court and the county or city and county shall enter into a contract for that service. The contract shall identify the scope of service, method of service delivery, term of agreement, anticipated service outcomes, and the cost of the service. The court and the county or city and county shall cooperate in developing and implementing the contract.
For any contract entered into after January 1, 2002, the amount of any indirect or overhead costs shall be individually stated in any contract together with the method of calculation of the indirect or overhead costs. This amount shall not contain items that are not otherwise allowable court operations. The Judicial Council may audit the county figures to ensure compliance with this section and to determine the reasonableness of the figures.
