When the Other Parent Won't Pay Child Support: What You Can Do

Another payment date has come and gone, and the child support you're counting on still isn't there. Maybe it's been late for months, maybe it stopped completely, or maybe the other parent pays a little here and there and calls it even. When your rent and your kids' needs depend on that money, the uncertainty is exhausting.

Here's the encouraging part: unpaid child support is one of the areas where the system has the most built-in enforcement tools. You generally don't have to chase the money yourself. This guide explains what to do first, how your state's child support agency can help, when going to court directly may make sense, and the mistakes that can quietly hurt you. Procedures vary by state, so treat this as a map, not a script.

What should you do first when child support isn't paid?

Confirm that you have an enforceable order, then start a written record of exactly what's owed and what's been paid. Everything else builds on those two things.

1. Find your order. Locate the most recent court or agency order. Note the amount, the due date, and how payments are supposed to be made, such as through a state disbursement unit or directly to you.
2. Check that it's the current order. If the support amount was changed, the newest order controls. An informal agreement between you two usually doesn't change the official amount.
3. Pull your payment history. If payments go through the state, the agency's records are the official ledger. If payments come directly to you, gather bank deposits, payment app history and receipts.
4. Start a payment ledger. One line per due date, as shown below.
5. Choose your enforcement route. Contact your child support agency, file with the court, or both if your court allows it.

If you don't have an order at all, there's nothing to enforce yet. A verbal promise or text agreement generally can't be collected the way an order can. The first step is establishing an order through your state's child support agency or the court. Our guide on how child support is calculated explains how the amount is usually set.

How does your state's child support agency help?

Every state runs a child support program under federal law, sometimes called the IV-D agency after the part of federal law that funds it. These agencies can locate parents, establish paternity, set and review orders, and enforce them, usually for free or a small fee.

If you've received certain public benefits, you may already have an agency case. If not, you can usually apply online, by phone or at a local office. Having these ready speeds things up:

• A copy of your current support order and any earlier orders
• Your payment ledger and proof of what was received
• The other parent's full name, date of birth and last known address
• Their employer, job title or type of work, if you know it
• Children's birth certificates and, if it applies, paternity paperwork

Agencies can use enforcement tools that a parent acting alone typically can't, and many of these happen without a court hearing:

• Income withholding. Support is taken directly from wages. Most orders include automatic withholding unless the parents or court arranged something else, and the agency can send a new withholding notice when the paying parent changes jobs.
• Tax refund intercepts. Federal and state tax refunds can be taken and applied to past-due support.
• Benefit intercepts. Unemployment and workers' compensation benefits can be reached.
• License actions. Driver's, professional and recreational licenses can be suspended for significant arrears.
• Passport denial. The federal government can deny a U.S. passport once past-due support passes a federal threshold.
• Liens and levies. Liens on property and levies on bank accounts.
• Credit reporting. Past-due support can be reported to credit bureaus.
• Court referral. The agency may bring the case to court, including for contempt.

Can you go to court yourself instead of using the agency?

In most places, yes. You can usually file a motion to enforce or a motion for contempt on your own or with a lawyer. Some courts ask you to coordinate with the agency if it's already handling your case, so check before you file.

If filing fees are a barrier, see how to ask the court to waive your filing fees. If you're considering the court route, how contempt generally works covers the process, what usually has to be proven, and what to expect at the hearing.

What if the other parent lost their job, moved or is self-employed?

A job loss doesn't automatically pause or reduce support. The paying parent generally has to ask the court or agency to modify the order, and until a new order is entered, the existing amount keeps coming due.

Job loss

Federal law generally prevents past-due support from being reduced retroactively. Any change usually reaches back no further than when a modification request was filed or served, depending on your state. Courts may also look at whether a job loss was voluntary. Many states allow a court to base support on what a parent could reasonably earn. If the other parent says they can't pay, the usual answer is that they need to ask for a modification, not simply stop paying.

Moved to another state

A uniform interstate law adopted by every state allows support orders to be enforced across state lines. Your agency can work with the agency where the other parent now lives.

Location unknown

Agencies have access to locate tools, including a federal parent locator service that searches employment and other records. Give your caseworker every detail you have: last known employer, address, phone, vehicle, relatives, social media.

Self-employed or paid in cash

Wage withholding doesn't work when there's no employer. Other tools, such as intercepts, license actions and court enforcement, become more important, and evidence of actual income (business pages, advertised services, lifestyle) may matter.

What should you avoid while support is unpaid?

Avoid anything that gives the other parent a counter-complaint or muddies the payment record.

• Keep following the parenting schedule. In most states, child support and parenting time are legally separate, so missed support generally isn't a reason to keep the children from the other parent. Our guide to withholding visitation explains why.
• Don't agree to informal reductions. Even if you agree in a text, the order usually stays the same unless a court or agency changes it.
• Don't accept cash without a dated receipt.
• Don't discuss the money with your children or post about it online.
• Don't threaten. Keep reminders short and factual.

That's it. No history, no commentary. If it goes unanswered, you don't need to send another. The agency or court process takes over from there.

How do you keep a payment record that holds up?

A simple ledger, kept consistently, is one of the most useful documents you can bring to an agency meeting or hearing. It turns "they never pay" into specific dates and amounts.

Behind each line, keep the proof: bank statements, payment app screenshots, receipts and agency printouts. Record partial payments exactly, and never round. Reliability is what makes a ledger persuasive. If you're organizing this alongside a custody case, a tool like Case Builder can keep each missed payment on a timeline linked to the records that show it. The timeline guide explains how that works.
