How Long Child Support Arrears Last: Collection Limits, Back Support and Forgiveness in New Mexico
New Mexico child support arrears keep drawing 4% interest until paid. We found no limitation period and no statute canceling past installments; the department may forgive interest on state-assigned support.
Do child support arrears expire in New Mexico?
We found no limitation period for unpaid support in the sections we read, and we are not stating one. Each unpaid installment is a final judgment (annotation to NMSA 56-8-4) and interest keeps accruing at 4% until it is paid (40-4-7.3). Ask a licensed New Mexico attorney how any judgment limitation or revival rule applies to your debt.
| Question | New Mexico rule |
|---|---|
| Interest | 4% on delinquent support until paid (40-4-7.3) |
| Forgiving interest | The department may forgive interest on state-assigned support (40-4-7.3(E)) |
| Amnesty program | The 2004 act required an arrears management program for interest amnesty |
| Stipulated reduction | Needed when one of several children reaches majority (McCurry, annotation to 40-4-11.4) |
| Time limit to collect | We found none in the sections we read; ask an attorney |
| Retroactive support | In a paternity case, support runs back to birth but not more than 12 years, unless a substantial showing is made (40-11-15, as amended in 2004) |
Can a judge forgive child support arrears in New Mexico?
We found no statute that lets a court cancel installments already due. Interest on state-assigned support can be forgiven by the department (40-4-7.3(E)). The way to limit arrears is to file a petition as soon as your circumstances change.
What should I do when one child turns 18 and others remain?
When a prior decree sets a lump-sum or periodic amount for two or more children and one reaches the age of majority, the best procedure for a parent seeking a reduction is a stipulated order authorizing it or a hearing, not self-help (annotation to NMSA 40-4-11.4, citing McCurry v. McCurry). Unpaid installments from a unilateral cut become arrears.
Can I get back support in a paternity case?
In a paternity judgment the court orders child support retroactive to the child’s birth, but not more than 12 years unless there is a substantial showing that paternity could not have been established and an action could not have been brought within 12 years, and it considers whether the father absconded or equitable defenses apply (NMSA 40-11-15, as amended in 2004).
What if interest is more than I can pay?
Ask the division in writing whether it will forgive accrued interest on state-assigned support, and offer a payment plan on the principal (40-4-7.3(E)). Interest on support owed to the other parent is not the division’s to forgive.
Is there a payment plan?
Compliance for license purposes means being in compliance with the judgment and order for support; the department issues a certified statement of compliance (40-5A-5). Ask the division for a written plan and keep every receipt.
Do arrears survive when the child turns 18?
Yes. Installments already owed stay owed and keep drawing interest. See the New Mexico child support end date calculator.
What should you do about a large balance?
Get the official balance, compare it with the New Mexico child support arrears calculator, ask about interest forgiveness and a payment plan, and if your circumstances changed, file a petition to modify right away.
