Child Support Enforcement

Child support enforcement is the legal process of compelling a parent to pay court-ordered child support. If your child’s other parent has stopped paying or has never paid, you have multiple enforcement tools available — from wage garnishment to license suspension to contempt of court. You do not need to accept non-payment, and in most cases, you do not need to hire an attorney to start the enforcement process.

Every state has a child support enforcement agency (typically part of the state’s Department of Social Services or Attorney General’s office) that will pursue enforcement on your behalf at little or no cost. Federal law requires these agencies to exist and to take action when support goes unpaid. Understanding the available remedies helps you choose the most effective approach for your situation.

State Child Support Enforcement Agencies

Your first step when child support goes unpaid should be contacting your state’s child support enforcement agency, often called the IV-D agency (named after Title IV-D of the Social Security Act). These agencies provide services regardless of your income level.

Services provided by enforcement agencies include:

• Locating the non-paying parent using databases that track employment, tax records, and other information
• Establishing paternity if it has not been legally determined
• Initiating wage withholding through the parent’s employer
• Filing enforcement actions with the court
• Coordinating with other states if the non-paying parent lives in a different jurisdiction

To open a case, contact your state’s agency and provide the existing child support order, the other parent’s identifying information (Social Security number, employer, address if known), and documentation of missed payments. Most agencies can open a case within a few weeks, though the timeline for actual collection varies depending on the circumstances.

If you need to understand how your support amount was originally determined, see our guide on how child support is calculated.

Wage Garnishment

Wage garnishment (also called income withholding) is the most effective and widely used enforcement tool. Under federal law, all new child support orders must include an automatic income withholding provision.

Here is how it works:

• The enforcement agency or court sends an Income Withholding Order to the non-paying parent’s employer
• The employer deducts the child support amount directly from the parent’s paycheck before they receive it
• The employer sends the payment to the state disbursement unit, which forwards it to the custodial parent
• Federal law limits garnishment to 50 to 65 percent of disposable income, depending on whether the paying parent supports another family and how far behind they are

Wage garnishment works well when the non-paying parent has steady employment with a cooperative employer. It is less effective for self-employed parents or those who work for cash. In those cases, other enforcement methods may be necessary.

License Suspension

States can suspend various licenses when a parent falls significantly behind on child support. The specific triggers vary, but most states take action when arrears reach a certain threshold or when payments are overdue by a set number of months.

Licenses that can be suspended include:

• Driver’s licenses — the most common and often the most motivating consequence
• Professional licenses — medical, legal, real estate, and other occupational licenses
• Recreational licenses — hunting, fishing, and boating licenses
• Passport denial — federal law requires the State Department to deny passport applications when arrears exceed $2,500

The process typically begins with a notice to the non-paying parent, giving them a window (usually 30 to 60 days) to make arrangements before the suspension takes effect. Many parents begin paying once they receive this notice, making it an effective motivator even before the suspension occurs.

Contempt of Court

When a parent willfully refuses to pay child support, the custodial parent or the enforcement agency can file a motion for contempt of court. This is one of the most powerful enforcement tools because it carries the possibility of jail time.

There are two types of contempt:

Civil contempt. The purpose is to compel compliance. The non-paying parent can avoid jail by making the required payments. Courts typically set a “purge amount” — a specific sum the parent must pay to avoid incarceration. Civil contempt is the more common approach in child support cases.

Criminal contempt. The purpose is to punish the violation. Criminal contempt can result in fines and jail time regardless of whether the parent later pays. This is reserved for the most egregious cases of willful non-payment.

To succeed in a contempt action, the custodial parent must show:

1. A valid child support order exists
2. The non-paying parent knew about the order
3. The parent failed to comply
4. The parent had the ability to pay but chose not to

The “ability to pay” element is critical. A parent who is genuinely unable to pay due to job loss, disability, or other circumstances may not be held in contempt, though they are still responsible for the arrears and should seek a modification of the order.

Tax Refund Intercept

The Federal Tax Refund Offset Program allows states to intercept federal and state tax refunds to cover past-due child support. This program is available when:

• Child support arrears exceed $150 for cases receiving public assistance
• Child support arrears exceed $500 for non-public-assistance cases

The process is handled through the state enforcement agency. When a non-paying parent files their tax return, the IRS checks the name and Social Security number against a database of parents who owe back support. If there is a match, the refund (or a portion of it) is redirected to pay the arrears.

If the non-paying parent has filed a joint return with a new spouse, the new spouse can file an “injured spouse” claim to recover their portion of the refund. The offset applies only to the non-paying parent’s share.

This method works well as a supplemental tool but should not be relied upon as a primary enforcement mechanism because it only produces results once a year and only if the parent is owed a refund.

Additional Enforcement Tools and Criminal Penalties

Beyond the primary methods described above, states have additional tools. Courts can order bank account levies to seize funds directly. Liens on property can be placed on real estate, vehicles, or other assets, preventing sale or refinancing until the lien is satisfied. Delinquent child support is reported to credit bureaus, affecting the non-paying parent’s credit score. Many states also intercept lottery winnings above a certain threshold.

In extreme cases, failure to pay child support can result in criminal prosecution. The federal Deadbeat Parents Punishment Act makes it a federal crime to willfully fail to pay support for a child living in another state when the arrears exceed $5,000 or are more than one year overdue. Penalties include up to 6 months in prison for misdemeanor charges (arrears over $5,000) and up to 2 years for felony charges (arrears over $10,000 or more than 2 years overdue). Most states also have their own criminal non-support statutes.

What to Do Next

If you are not receiving court-ordered child support, take these steps:

1. Document the non-payment. Keep records of all missed payments, partial payments, and any communication with the other parent about support. Your payment records through the state disbursement unit are the most reliable documentation.
2. Contact your state’s child support enforcement agency. Open a case if you do not already have one. The agency can pursue wage garnishment, license suspension, and other remedies at little or no cost to you.
3. Consider filing a contempt motion. If the enforcement agency’s efforts are insufficient or too slow, you can file a contempt motion directly with the court. An attorney can help with this process.
4. Do not withhold visitation. Regardless of whether support is being paid, you cannot deny the other parent court-ordered parenting time. Child support and visitation are separate legal issues, and withholding visitation can hurt your own custody position.
5. Get legal guidance. If you are dealing with significant arrears or a parent who is actively evading payment, consult with a family law attorney who can evaluate the most effective enforcement strategy for your situation.
