California Department of Child Support Services

There are 49 child support agencies across California that establish and enforce child support and medical support orders. Either parent or any guardian of a child can open a child support case, whether or not there is an existing child support order, and a case is automatically opened when a child receives public assistance. All case services are handled at county or regional level and all child support-related questions should be first routed to the agency in your county or region of residence.
