CalWORKS, Medi-Cal, or Foster Care Cases

A case will automatically be opened for any child receiving CalWORKS, Foster Care, or Medi-Cal benefits. In these cases, the Department of Social Services will refer the case to the Department of Child Support Services, unless a good cause exemption is granted. In order to maintain their grant eligibility, parents who apply for public assistance must cooperate with the child support caseworker to establish paternity and to obtain child support payments. Except in a foster care case, the first $50 of child support collected each month for children receiving public assistance is paid directly to the primary custodial party. The remainder of the child support payment collected goes to the County for reimbursement of the welfare benefits. 

Domestic Violence Cases

The Department of Child Support Services understands the extremely sensitive nature of situations involving domestic violence. Special provisions are in place for dealing with child support cases where domestic violence is an issue. If you need help collecting child support from a violent or potentially violent individual, please inform child support staff immediately so that the proper precautions may be taken to protect you and the child(ren).
