Child support arrears are unpaid child support amounts that were owed under a support order but not paid when due.
Arrears can accumulate over time and may be subject to enforcement procedures, interest, or collection remedies depending on the jurisdiction.
Why child support arrears matter
Arrears can affect parents, children, and court enforcement. They may remain enforceable even after a child becomes an adult or after future support is changed, depending on the law that applies.
Because arrears come from an existing order, a later change in income does not necessarily erase past-due amounts.
Where child support arrears appear
Arrears appear in support enforcement cases, modification requests, contempt proceedings, wage withholding, tax refund intercepts, license actions, and payment record disputes.
They are often calculated from agency records, court payment histories, or documented direct payments.
How it differs from nearby terms
Child support is the ongoing obligation. Child support arrears are amounts already past due.
A child support modification may change future payments, while arrears concern what was not paid under earlier orders.
Practical example
A parent was ordered to pay $500 per month but paid only $300 for six months. The unpaid $200 per month becomes arrears, separate from the current monthly support obligation.
