How Long Child Support Arrears Last: Collection Limits, Back Support and Forgiveness in Utah
Utah child support arrears can be enforced until four years after the youngest child reaches majority, or eight years from a sum certain judgment, whichever is longer; due payments cannot be reduced retroactively.
Can Utah child support arrears be changed?
Not for payments that are already due: each installment is not subject to retroactive modification except for the period a modification is pending, from service (Utah Code 81-7-102(4)-(5)).
| Question | Utah rule |
|---|---|
| Due payments | Not subject to retroactive modification (81-7-102(4)(c)) |
| Sum certain judgment | Enforceable eight years from entry, and renewable (78B-5-202(6)) |
| Monthly judgments under the order | Enforceable until four years after the youngest child reaches majority (78B-5-202(6)) |
| Which period applies | The longer one (78B-5-202(6)(b)) |
| Age of majority | 18, or earlier by marriage (R527-250-8) |
| Another state’s order | The longer of Utah’s or the issuing state’s limit applies (81-8-604) |
Do child support arrears expire in Utah?
Yes, after a duration period. A child support order or a sum certain judgment for past-due support may be enforced within four years after the date the youngest child reaches majority, or eight years from the date of entry of the sum certain judgment, and the longer period applies in every order; a sum certain judgment may be renewed to extend the duration (Utah Code 78B-5-202(6)).
How does that work in an example?
Suppose the youngest child turns 18 on June 1, 2030 and you get a sum certain judgment for arrears on January 15, 2029. The monthly judgments under the order can be enforced until June 1, 2034 (majority plus four years). The sum certain judgment can be enforced until January 15, 2037 (eight years from entry), unless renewed. The longer date applies to each, so the sum certain judgment outlasts the monthly judgments here.
What can extend the period?
Renewing a sum certain judgment; a parent’s time out of state in some cases; bankruptcy payments; criminal restitution orders, which are not bound by the duration statute (CS 812P). Ask a licensed Utah attorney which applies.
What if the child support order is from another state?
In a proceeding for arrears under a registered support order, the statute of limitations of Utah or of the issuing state or country, whichever is longer, applies (Utah Code 81-8-604, as quoted in CS 812P).
What happens when the period runs out?
The agency adjusts the expired debt to zero, ends income withholding and other enforcement, and closes the case after sending a 60-day closure notice, but it may keep taking voluntary payments if the parent chooses to keep paying (CS 812P).
Does expiry mean the parent no longer owes it?
For state debt in cases where a child was in state care, the agency says only that it stops providing enforcement and withholding after the period passes, not that the debt is forgiven (CS 812P). Ask a licensed Utah attorney about private claims.
Can the other parent agree to forgive arrears?
The sections we read do not describe private forgiveness, and due payments cannot be modified retroactively. Ask the court to approve any settlement, and the agency if it holds an assigned share.
What should you do about a large balance?
Get the official balance, compare it with the Utah child support arrears calculator, ask for a payment arrangement, and if your circumstances changed, file to modify right away.
