Enforcing Child Support Orders in New Hampshire

When a parent falls behind on child support in New Hampshire, the Division of Child Support Services (DCSS) has a powerful arsenal of enforcement tools to collect what's owed. From automatic wage withholding under RSA 458-B to property liens under RSA 161-C, custodial parents have real leverage. The NH DCSS enforcement division administers most of these actions, and parents can also pursue remedies directly through the Circuit Court—Family Division. This guide explains each mechanism, the statutory authority behind it, and what to expect.

Wage Withholding and Income Assignment

The primary New Hampshire child support enforcement tool is immediate income withholding. Under RSA 458-B, all support orders include a wage assignment provision. For orders issued or modified after January 1, 1994, the assignment is mandatory. When the state provides public assistance, withholding takes effect immediately. Otherwise, courts may suspend immediate withholding only under narrow conditions—such as approved written alternative arrangements—but withholding automatically triggers when a one-month delinquency accrues.

Employers must remit withheld amounts on the same day the employee is paid. Federal law under the Consumer Credit Protection Act (CCPA) caps total withholding at 50% of disposable earnings if the paying parent supports another family, or 60% if they do not. An extra 5% applies when arrears exceed 12 weeks, raising the maximums to 55% and 65% respectively. Employers may deduct a $1 administrative fee per withholding under NH law, and they face penalties—including potential misdemeanor fines—for failing to remit or for retaliating against an employee subject to withholding.

New Hampshire also intercepts unemployment benefits. When a support order is payable through DCSS and the obligor receives NH unemployment, the state may withhold 20% of the weekly benefit amount toward current support.

License Suspensions

Under RSA 161-B:11, DCSS can certify noncompliance with a support order to licensing boards for suspension, revocation, or denial of licenses. This applies to three categories:

• Driver's licenses (including commercial driver's licenses)
• Occupational and professional licenses issued by state boards
• Sporting licenses (hunting and fishing)

DCSS provides advance notice before certifying a case, giving the noncompliant parent an opportunity to pay in full, enter a repayment agreement, or contest the action. Reinstatement requires documented compliance. For more on how New Hampshire calculates child support amounts, see our detailed guide.

Tax Refund Intercepts and Passport Denial

DCSS submits past-due cases monthly to the federal Treasury Offset Program (TOP), which intercepts federal tax refunds when arrears exceed $500 for private cases or $150 for public assistance (TANF) cases. Advance notice is sent before certification.

Because New Hampshire has no state income tax on wages or investment income (the Interest & Dividends tax was repealed effective January 1, 2025), there is no state tax refund to intercept. However, the federal offset remains a significant enforcement lever.

At the federal level, the U.S. Department of State will deny, revoke, or restrict a passport when child support arrears exceed $2,500. DCSS routinely submits qualifying cases to the State Department. The passport hold remains until arrears are resolved or the case is decertified.

Property Liens and Bank Levies

Under RSA 161-C:10, after required notice periods, stated child support arrears become a lien on all real and personal property of the responsible parent. Once the lien is filed, the parent cannot sell or refinance real property without satisfying the debt. Third parties with notice must honor the lien.

DCSS can go further under RSA 161-C:13: it may seize and sell property subject to the lien and may foreclose the lien through the superior court, with costs and reasonable attorney's fees added to the judgment.

New Hampshire also authorizes quarterly automated data matches with financial institutions under RSA 161-C:3-a. When DCSS locates accounts belonging to a parent with arrears, it can levy those accounts to satisfy the debt. This bank-levy tool is the backbone of enforcement against self-employed or judgment-proof obligors. For a broader overview of the divorce process, see our New Hampshire divorce timeline guide.

Lottery and Insurance Settlement Intercepts

Under RSA 284, the NH Lottery must match winners against the DCSS arrears database and intercept prizes—generally those subject to IRS Form W-2G reporting—up to the amount of arrears owed. This creates an unexpected enforcement event for any obligor who wins.

Additionally, under RSA 161-C:3-f, DCSS may intercept insurance settlement payments or judgments for obligors who are subject to a child-support lien and owe past-due support. Workers' compensation settlements, personal injury awards, and other insurance disbursements are all subject to intercept.

Contempt of Court

When administrative enforcement tools are insufficient, DCSS or the custodial parent can seek a show-cause hearing in Circuit Court. If the court finds willful noncompliance, remedies include ordering immediate lump-sum payments, modifying payment schedules, and—in serious cases—incarceration until the parent pays the purge amount set by the court. Contempt is the enforcement tool of last resort, reserved for parents who have the ability to pay but refuse to do so.
