CA Fam Code Section 10008

(a)

Except as provided in subdivision (b), nothing in this chapter shall be construed to apply to a child for whom services are provided or required to be provided by a local child support agency pursuant to Section 17400.

(b)

In cases in which the services of the local child support agency are provided pursuant to Section 17400, either parent may utilize the services of the family law facilitator that are specified in Section 10004. In order for a custodial parent who is receiving the services of the local child support agency pursuant to Section 17400 to utilize the services specified in Section 10005 relating to support, the custodial parent must obtain written authorization from the local child support agency. It is not the intent of the Legislature in enacting this section to limit the duties of local child support agencies with respect to seeking child support payments or to in any way limit or supersede other provisions of this code respecting temporary child support.
