About OIG

Who We Are

Since its 1976 establishment, the Office of Inspector General (OIG) has been at the forefront of the Nation's efforts to fight waste, fraud and abuse and to improving the efficiency of Medicare, Medicaid and more than 100 other Department of Health & Human Services (HHS) programs. OIG has approximately 1,600 personnel. The majority of the agency’s resources go towards the oversight of Medicare and Medicaid — programs that represent a significant part of the Federal budget and that affect this country's most vulnerable citizens.

If you have a question or problem related to a child support enforcement case, please contact your State's child support enforcement office. These offices handle the majority of child support cases and issues, including the day-to-day operations of child support collections.

Please note that even if a case appears to meet the criteria for Federal prosecution, there are many elements that go into the decision to investigate and prosecute such cases at the Federal level. The ultimate decision on whether to prosecute a child support case at the Federal level lies with the Department of Justice. (For more information, please see the U.S. Department of Justice's Citizen's Guide to Federal Law on Child Support Enforcement).
