(a) The court may order that service of the assignment order be stayed only if the court makes a finding of good cause or if an alternative arrangement exists for payment in accordance with paragraph (2) of subdivision (b). Notwithstanding any other provision of law, service of wage assignments issued for foreign orders for support, and service of foreign orders for the assignment of wages registered pursuant to Chapter 6 (commencing with Section 5700.601) of Part 6 shall not be stayed pursuant to this subdivision.
(b) For purposes of this section, good cause or an alternative arrangement for staying an assignment order is as follows:
(1) Good cause for staying a wage assignment exists only when all of the following conditions exist:
(A) The court provides a written explanation of why the stay of the wage assignment would be in the best interests of the child.
(B) The obligor has a history of uninterrupted, full, and timely payment, other than through a wage assignment or other mandatory process of previously ordered support, during the previous 12 months.
(C) The obligor does not owe an arrearage for prior support.
(D) The obligor proves, and the court finds, by clear and convincing evidence that service of the wage assignment would cause
extraordinary hardship upon the obligor. Whenever possible, the court shall specify a date that any stay ordered under this section will automatically terminate.
(2) An alternative arrangement for staying a wage assignment order shall require a written agreement between the parties that provides for payment of the support obligation as ordered other than through the immediate service of a wage assignment. Any agreement between the parties which includes the staying of a service of a wage assignment shall include the concurrence of the local child support agency in any case in which support is ordered to be paid through a county officer designated for that purpose. The execution of an agreement pursuant to this paragraph shall not preclude a party from thereafter seeking a wage assignment in accordance with the procedures specified in Section
5261 upon violation of the agreement.
