Colorado uses the Uniform Interstate Family Support Act to register and enforce orders across state lines. UIFSA lets your Colorado order be enforced where the obligor lives, works, or has assets. State agencies and courts can coordinate to withhold income, collect arrears, and take other actions. You can ask the court or the local child support services unit to initiate interstate enforcement. The Judicial Branch’s child support page provides the statutory basis and references for UIFSA. Interstate tools help prevent obligors from avoiding support by moving away.
