The Department of Child Support Services is responsible for establishing and enforcing orders for child support.
Our Mission: Children deserve the security of having their needs met. Parents are responsible for providing financial, medical and emotional support for their children. To achieve these goals, we establish and enforce child support orders, treating all parties with respect, and serve the community through outreach and education.
Apply for Services
A child support services case can be opened by either parent, or a legal guardian, whether or not a child support court order exists. If you already have a court order, opening a case offers neutral assistance with every part of the process, keeps records, and helps both parties stay on track. If you do not have a case, applying for child support means your local child support agency will help you locate the other parent, establish legal paternity/parentage if required, get a court order and see that it is enforced in every state and many foreign countries.
To apply for services online, go to the California Child Support Services website. (Mire en la esquina superior derecha para cambiar el formulario a español.)
