Our Mission

The mission of the Mariposa County Department of Child Support Services is to 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. 

Having a case with Child Support Services creates a record of all child support payments, provides a neutral go-between for parents, and can help both parents avoid court and assist with navigating the child support system. Child Support Services staff act in the public interest and do not represent either side of a child support case. A complete list of services provided can be found here; these services are provided at little or no cost.

If you are thinking of opening a case, or have been named in a child support case, contact us right away. Your local agency can help both of you know what to expect, and will work with you to make the child support process as stress-free as possible. We can even help you work out an agreement for child support and avoid court.
