California Code, Family Code - FAM § 5240

(1) With regard to orders for spousal support, the death or remarriage of the spouse to whom support is owed.

(2) With regard to orders for child support, the death or emancipation of the child for whom support is owed.

(3) The court determines that there is good cause, as defined in Section 5260, to terminate the assignment order.  This subdivision does not apply if there has been more than one application for an assignment order.

(4) The obligor meets the conditions of an alternative arrangement specified in paragraph (2) of subdivision (b) of Section 5260, and a wage assignment has not been previously terminated and subsequently initiated.

(5) There is no longer a current order for support.

(6) The termination of the stay of an assignment order under Section 5261 was improper, but only if that termination was based upon the obligor's failure to make timely support payments as described in subdivision (b) of Section 5261.

(7) The employer or agency designated to provide services under Title IV-D of the Social Security Act or the State Disbursement Unit is unable to deliver payment for a period of six months due to the failure of the obligee to notify that employer or agency or the State Disbursement Unit of a change in the obligee's address.
