Child Support Services

Child Support Services

The mission of the Colorado Child Support Services (CSS) Program is to assure that all children receive financial and medical support from both parents. This is accomplished by locating each parent, establishing paternity and support obligations, and enforcing those obligations. 

The CSS Program puts children first by helping both parents assume responsibility for the economic and social well-being, health, and stability of their children. We recognize that children benefit from positive, ongoing relationships with both parents.

Visit the Colorado Division of CSS website for information about how to start a case, apply for child support services, how to create an online account to view specific information on your child support case, different ways to make and receive child support payments, and how and when to request changes to a child support order.
