What is the statute of limitations on collecting a court ordered child support?
None under federal law with 3-15% of annual interest penalties.
While there is no statue of limitation for collecting court ordered unpaid back child support, there is for unordered support...the age of 21 of the dependent child. The child at the age of 18 may sue the noncustodial parent for unpaid support that was not ordered by the courts. This has been done at least twice.
