Fam. Code, § 17440

(a) The Department of Child Support Services shall work with all branches of the United States military and the National Guard to ensure that information is made available regarding the rights and abilities of activated service members to have their support orders modified based on a change in income resulting from their activation, or other change of circumstance affecting the child support calculation, or to have a portion of their child support arrearages compromised pursuant to Section 17560.

(b) No later than 90 days after the effective date of this section, the department shall develop a form for completion by the service member that will allow the local child support agency to proceed with a motion for modification without the service member being required to appear. The form shall contain only the information necessary for the local child support agency to proceed with the motion.

(c) Within five business days of receipt of a properly completed form, the local child support agency shall bring a motion to modify the support order. The local child support agency shall bring the motion if the change in circumstances would result in any change in the dollar amount of the support order.

(d) The department shall work with the United States military to have this form and the form developed pursuant to Section 3651 distributed at all mobilization stations or other appropriate locations to ensure timely notification to all activated personnel of their rights and responsibilities.
