Child support information is available from a number of government agencies. The U.S. Department of Health and Human Services provides data through the Administration for Children and Families (ACF). It covers frequently asked questions and links to support enforcement divisions for each state. The DOJ provides information about how Federal prosecution of child support evaders works. This is relevant when a non-custodial parent moves across state lines in order to get out of making payments. Each state also provides a dot-gov website linked to their judicial system that makes more specific child support information available to residents. These can be good places to search for child support calculation worksheets. The National Child Support Enforcement Agency offers a full list of relevant links for each state.
