California Code, Code of Civil Procedure - CCP § 704.114

(a) Notwithstanding any other provision of law, service of an earnings assignment order for support, or an order or notice to withhold income for child support on any public entity described in Section 704.110, other than the United States government, creates a lien on all employee contributions in the amount necessary to satisfy a support judgment as determined under Section 695.210 to the extent that the judgment remains enforceable.

(b) The public entity shall comply with any request for a return of employee contributions by an employee named in the order or notice to withhold by delivering the contributions to the clerk of the court in which the support order was awarded or last registered, unless the entity has received a certified copy of an order or administrative notice terminating the earnings assignment order for support.

(c) Upon receipt of moneys pursuant to this section, the clerk of the court, within 10 days, shall send written notice of the receipt of the deposit to the parties and to the local child support agency enforcing any order pursuant to Section 17400 of the Family Code.

(d) Moneys received pursuant to this section are subject to any procedure available to enforce an order for support, but if no enforcement procedure is commenced after 30 days have elapsed from the date the notice of receipt is sent, the clerk shall, upon request, return the moneys to the public entity that delivered the moneys to the court unless the public entity has informed the court in writing that the moneys shall be released to the employee.

(e) A court shall not directly or indirectly condition the issuance, modification, or termination of, or condition the terms or conditions of, any order for support upon the making of a request for the return of employee contributions by an employee.
