Frequently Asked Questions

Does child support interest compound monthly or annually? +

In most states, statutory interest on child support is calculated as simple interest on the unpaid principal balance, though delinquent judgments may be renewed periodically.

Can child support interest be waived if parents agree? +

If arrears are owed to the state (due to past public assistance / TANF), the state must approve any compromise. If owed solely to the custodial parent, some states allow private stipulations waiving interest.
