California Family Code
For a support order first issued or modified before July 1, 1990, this article provides a procedure for obtaining an earnings assignment order for support when the court in ordering support or modification of support did not issue an assignment order.
The obligee seeking issuance of an assignment order to enforce a support order described in Section 5250 may use the procedure set forth in this article by filing an application under Section 5252, or by notice of motion or order to show cause, or pursuant to subdivision (b) of Section 5230.
(a) An assignment order under this article may be issued only upon an application signed under penalty of perjury by the obligee that the obligor is in default in support payments in a sum equal to the amount of support payable for one month, for any other occurrence specified by the court in the support order, or earlier by court order if requested by the local child support agency or the obligor.
(b) If the order for support does not contain a provision for an earnings assignment order for support, the application shall state that the obligee has given the obligor a written notice of the obligee's intent to seek an assignment order if there is a default in support payments and that the notice was transmitted by first-class mail, postage prepaid, or personally served at least 15 days before the date of the filing of the application. The written notice of the intent to seek an assignment order may be given at any time, including at the time of filing a petition or complaint in which support is requested or at any time subsequent thereto. The obligor may at any time waive the written notice required by this subdivision.
(c) In addition to any other penalty provided by law, the filing of the application with knowledge of the falsity of the declaration or notice is punishable as a contempt pursuant to Section 1209 of the Code of Civil Procedure.
Upon receipt of the application, the court shall issue, without notice to the obligor, an assignment order requiring the employer of the obligor to pay to the obligee or the State Disbursement Unit that portion of the earnings of the obligor due or to become due in the future as will be sufficient to pay an amount to cover both of the following:
(a) The amount ordered by the court for support.
(b) An amount which shall be ordered by the court to be paid toward the liquidation of any arrearage or past due support amount.
