California Code, Family Code - FAM § 17208

(a) The department shall reduce the cost of, and increase the speed and efficiency of, child support enforcement operations. It is the intent of the Legislature to operate the child support enforcement program through local child support agencies without a net increase in state General Fund or county general fund costs, considering all increases to the General Fund as a result of increased collections and welfare recoupment.

(b) The department shall maximize the use of federal funds available for the costs of administering a child support services department, and to the maximum extent feasible, obtain funds from federal financial incentives for the efficient collection of child support, to defray the remaining costs of administration of the department consistent with effective and efficient support enforcement.

(c) Effective October 1, 2019, the Department of Child Support Services shall impose an administrative service fee in the amount of thirty-five dollars ($35) on a never-assisted custodial party receiving services from the California child support program for order establishment, enforcement, and collection services provided. The annual amount of child support payments collected on behalf of the custodial party must be five hundred fifty dollars ($550) or more before an administrative service fee is imposed pursuant to this subdivision. The fee shall be deducted from the custodial party's collection payment at the time the collection payments for that year have reached levels specified by the department.
