A CalWORKS child support case is opened when a custodial parent applies for and receives CalWORKS benefits. The county Welfare Department informs the FSD or local child support agency when CalWORKS benefits are granted, and a child support case is opened by the FSD or local child support agency. The FSD or local child support agency does not determine welfare eligibility. The county Welfare Department determines a CalWORKS grant amount, food stamp eligibility and Medi­Cal eligibility, and the FSD or local child support agency establishes and enforces the child support order.
