Every state has its own IV-D agencies that will help Colorado establish paternity, support orders and/or enforce a support a child support order across state lines. Colorado also has the ability to send an income assignment directly to employers in other states.

The primary legal tool for interstate cases is the Uniform Interstate Family Support Act (UIFSA). UIFSA gives states the power to reach beyond their borders for the establishment and enforcement of support orders. It also allows states to enforce a support order issued in another state. If legal action is needed to establish or enforce an order in another state, UIFSA makes the process easier, as state child support agencies must help each other. However, the county CSE Unit must rely on the other state’s laws, regulations, procedures and personnel to take action on the case. The other state may assess fees or withhold fees from the support collected.
