As the Contra Costa County agency responsible for establishing, collecting, and distributing child and medical support for minors, the Department of Child Support Services (DCSS) is an important part of California's effort to nurture and protect children and to help them and their families achieve self-sufficiency.
We hope parents and guardians throughout Contra Costa County will find help through the resources provided here and through our office.
