How Do I Get Child Support Enforced?

The fastest path to collecting unpaid child support is to open or reopen a case with your state's child support enforcement (CSE) agency, which can garnish the other parent's wages, intercept their tax refund, suspend licenses, and place liens for free. If you have a court order, you can also ask the court that issued it to hold the other parent in contempt. You do not have to choose just one route, and you do not need a lawyer to start, though a lawyer can speed up contempt and complex collection.

Below is a calm, practical walkthrough of every tool available to you, what each one does, and the order most parents should try them in.

First: you need a child support order

Enforcement tools only work once a court or agency has entered a child support order setting a specific dollar amount. If you have an informal arrangement but no order, your first step is to get one, either through your state CSE agency (which can establish paternity and a support amount) or through family court. You cannot garnish wages or pursue contempt for support that was never legally ordered.

If you already have an order, gather it along with a record of what has actually been paid versus what was owed. A clear payment ledger (dates, amounts, missed payments) is the single most useful document you can bring to any enforcement effort.

Your strongest free tool: the state child support enforcement agency

Every U.S. state and territory runs a child support enforcement program (often called the "IV-D" program because it is required under Title IV-D of the federal Social Security Act in order for states to receive federal funding). These agencies exist specifically to collect support, and their services are free or very low cost.

Once your case is open, the agency can use powerful collection tools, most of which are backed by federal law that requires every state to have them available:

• Income (wage) withholding — the order is sent directly to the other parent's employer, who deducts support from each paycheck and forwards it. Under federal law (42 U.S.C. 666(a)(1)), states must make income withholding available, and for most orders it is automatic. This is the most reliable collection method when the other parent has a steady job.
• Federal tax refund offset — past-due support can be intercepted from the other parent's federal income tax refund. This is authorized under 42 U.S.C. 664. There are minimum past-due thresholds, and the offset typically happens during tax-filing season, so it is powerful but not instant.
• Liens — the agency can place a lien on real estate, vehicles, or bank accounts for past-due support (42 U.S.C. 666(a)(4)).
• License suspension — driver's, professional, and recreational licenses can be suspended for nonpayment (42 U.S.C. 666(a)(16)). The threat of losing a driver's or professional license often prompts payment.
• Credit bureau reporting and passport denial — large arrears can be reported to credit agencies and can block issuance or renewal of a U.S. passport.

To open a case, search for your state's child support or "Department of Child Support Services" / "Office of Child Support" website, or call your county's family services office. You will provide the order, the other parent's information (employer, address, Social Security number if you have it), and your payment records.

Going to court: contempt

If the other parent has the ability to pay but simply refuses, you can file a motion for contempt (sometimes called "enforcement" or "show cause") in the court that issued the support order. Contempt asks the judge to find that the parent willfully violated a court order.

If the judge finds contempt, possible consequences include:

• An order to pay the arrears immediately or on a strict payment plan
• Payment of your attorney's fees and court costs
• Fines
• Jail time (often "conditional" — the parent can avoid or end jail by paying a set "purge" amount)

A key limit: contempt generally requires that the nonpayment was willful. A parent who genuinely cannot pay (for example, because of job loss or disability) usually cannot be jailed for contempt, though the debt does not disappear. That leads to an important rule many parents misunderstand below.

Time-sensitive: past-due support cannot be erased, but future amounts can change

Under the federal Bradley Amendment (42 U.S.C. 666(a)(9)(C)), child support payments that have already come due (accrued) cannot be retroactively reduced or forgiven by a court, even by the judge who issued the order. Each missed payment becomes a fixed debt, often called a judgment by operation of law, that keeps accruing.

The flip side matters for the paying parent: if their income drops, they must file a motion to modify support right away. A modification can only reach back to the date the modification motion was filed or served (which point applies varies by state) — never earlier. Waiting to file means arrears keep piling up at the old amount in the meantime. So if you are owed money, delay rarely helps the other parent escape the debt; and if you are the one who can no longer pay, file to modify immediately rather than just stopping payments.

If the other parent is in the military

Military pay can be garnished for child support through the Defense Finance and Accounting Service (DFAS), and the armed services take support obligations seriously. Two federal laws affect how this plays out:

• The Servicemembers Civil Relief Act (SCRA), 50 U.S.C. 3932, lets an active-duty parent whose military duties materially affect their ability to appear request a court stay (pause) of at least 90 days in a civil case, including support proceedings, and protects them from default judgments. This can slow enforcement but does not cancel the obligation.
• The Uniformed Services Former Spouses' Protection Act (USFSPA), 10 U.S.C. 1408, is primarily about dividing military retirement pay in divorce, but its mechanisms also allow direct payment from retired pay in some circumstances. Note that USFSPA does not create a 50/50 split of retirement; how retired pay is divided is decided under state property-division law.

For military cases, your state CSE agency can coordinate with DFAS, which is usually the most efficient route.

If the other parent lives in another state

Child support is enforceable across state lines. Every state has adopted the Uniform Interstate Family Support Act (UIFSA), which lets your home state's order be registered and enforced where the other parent now lives — including direct income withholding sent to an out-of-state employer. Your CSE agency handles this interstate coordination for you; you generally do not have to travel or hire a lawyer in the other state.

What you can do — step by step

1. Confirm you have an order. If not, contact your state CSE agency or family court to establish one first.
2. Build a payment ledger. List every payment due, every payment received, and the running total owed. Keep proof (bank records, the order itself).
3. Open or reopen a case with your state child support enforcement agency. This is free and unlocks wage withholding, tax-refund offset, liens, and license suspension.
4. Request income withholding if the other parent is employed and it is not already in place — it is the most dependable method.
5. Provide locate information. Give the agency the other parent's employer, address, and Social Security number if you have them; agencies also have tools to find this.
6. File for contempt in the issuing court if the parent can pay but won't. Consider a lawyer here, especially if you want attorney's fees ordered against the other parent.
7. Do not stop documenting. Keep your ledger current; arrears keep accruing and cannot be retroactively wiped out.
8. Never withhold visitation as leverage. Support and custody/visitation are legally separate; refusing court-ordered visitation can hurt your own case.

What to expect on timing

Wage withholding can take effect within a few weeks once an employer is identified. Tax-refund offsets are tied to filing season. Contempt hearings depend on your court's calendar and can take weeks to a few months to schedule. Locating a parent who has changed jobs or moved out of state adds time. Persistence and good records are what move these cases.
