How Long Child Support Arrears Last: Collection Limits, Back Support and Forgiveness in Arizona
Arizona child support judgments are exempt from renewal and enforceable until paid in full. An obligor can assert unreasonable delay if collection begins more than ten years after the youngest child’s emancipation, and arrears can be reduced by custody defenses, credits or a written waiver.
Do child support arrears expire in Arizona?
A judgment for support, and for associated costs and attorney fees, is exempt from renewal and enforceable until paid in full (A.R.S. 25-503(M)). But if the person owed support or the department tries to collect more than ten years after the youngest child’s emancipation, the obligor may assert unreasonable delay and has the burden to prove it; on a finding of unreasonable delay a tribunal may decide that some or all of the debt is no longer collectible after the date of the finding (25-503(L)).
| Question | Arizona rule |
|---|---|
| Judgment | Exempt from renewal and enforceable until paid in full (25-503(M)) |
| Delay defense | Collection more than ten years after the youngest child’s emancipation: the obligor may assert unreasonable delay and has the burden (25-503(L)) |
| Custody defense | Voluntary relinquishment of physical custody to the obligor, in whole or in part (25-503(J)-(K)) |
| Credits and waivers | Only by court order or a written affidavit of direct payment or waiver filed with the clerk (25-510(G)-(H)) |
| Changing the payment on arrears | The court may adjust it on a substantial and continuing change (Guidelines XVI.C) |
| Retroactive changes | Not for arrears accrued before notice of the motion (25-327(A)) |
Can a judge forgive child support arrears in Arizona?
Not by simply reducing past-due installments: each vests when due and a modification cannot reach arrears that accrued before notice of the motion (A.R.S. 25-327(A)). Arrears can be reduced through the defenses and credits the statutes provide, such as unreasonable delay, voluntary relinquishment of custody, equitable credits after a hearing or a written waiver by the person entitled to support.
What is the voluntary relinquishment defense?
Voluntary relinquishment of physical custody of a child to the obligor from the obligee is an affirmative defense, in whole or in part, to a petition to enforce arrears. In deciding whether the relinquishment was voluntary the court considers any evidence or history of domestic violence, parental kidnapping or custodial interference. The relinquishment must have lasted longer than any court-ordered parenting time, and the obligor must have supplied actual support for the child (25-503(J)-(K)).
Can the person owed support waive arrears?
A credit against arrears other than by court order can be made only by a written affidavit of direct payment or waiver of support arrearages signed by the person entitled to receive support, or by that person and the obligor, filed with the clerk. In a Title IV-D case the affidavit does not reduce what is owed to the department without its written approval (A.R.S. 25-510(H)).
Can the payment on arrears be lowered?
Yes, on a showing of substantial and continuing changed circumstances the court may adjust the payment on arrears; the court must consider the total arrears, the accruing interest and the time needed to pay, and if the payment is below the accruing monthly interest it must say why (Guidelines Section XVI).
Do arrears survive when support ends?
Yes. When current support terminates but arrears remain, the income withholding order may remain in effect until the arrears and accruing interest are paid (Guidelines XVI.D). See the Arizona child support end date calculator.
What should you do about a large balance?
Get the official figure, compare it with the Arizona child support arrears calculator, ask about a payment plan and, if your circumstances changed, file to modify the order right away.
