Find Your State Child Support Office

Every state runs its own child support program — its own application process, payment system, and enforcement tools. This directory links directly to the official agency for all 50 states and Washington, D.C., so you can find contact information, application steps, and payment portals without digging through state government websites.

Helpful Resources

No two states run child support the same way

Some states run child support out of the Attorney General's office, others through Health and Human Services or a county-level agency — and that changes who you call, how you apply, and how a case moves through the system. Guideline calculations, payment processing, and enforcement remedies for missed payments also vary by state. The pages above point you to the office that actually handles your state's cases, so you're not guessing which agency to contact.
