When a child support case is closed, the state enforcement agency stops actively working it, but the underlying court order and any unpaid support remain in force. Closure is an administrative step by the agency. It does not cancel the obligation to pay, does not erase arrears, and does not stop interest from accruing. Many of the collection tools that were already in motion keep operating in the background.
Closure Is an Agency Action, Not the End of the Order
Most child support cases run through a state’s Title IV-D program, the federally funded enforcement system. When people say a case was “closed,” they almost always mean the IV-D agency has stopped providing services: no more payment tracking, no more locate requests, no more garnishments initiated on the custodial parent’s behalf.
That is not the same thing as ending the court order. If a judge ordered one parent to pay $800 a month until the child turns 18, that obligation stands whether or not the agency has an open file. The agency is a collection tool. The order is the source of the debt. Confusing the two is how arrears balloon: a paying parent assumes nothing is owed, stops paying, and years later finds out the debt was growing the whole time.
Ending the obligation itself requires going back to court to modify or terminate the order. That is a separate proceeding from administrative closure.
Why Agencies Close Cases
Federal regulation lists the specific circumstances under which a IV-D agency can close a case, and every state has to follow those criteria.1eCFR. 45 CFR 303.11 – Case Closure Criteria The common ones include: the children have aged out and no current order exists; the noncustodial parent has died with no reachable estate; the agency cannot locate the paying parent despite diligent efforts over the required search period; paternity cannot be established; the parents are living together; remaining arrears are small and assigned only to the state; or the custodial parent has asked the agency to stop.
None of those criteria say the debt is wiped out. They just describe when the agency is allowed to walk away.
The 60-Day Notice and Your Right to Object
Before an agency actually closes a case, it has to send the custodial parent written notice at least 60 calendar days in advance, explaining the reason.1eCFR. 45 CFR 303.11 – Case Closure Criteria That window is your chance to push back. If you provide new information that could lead to establishing paternity, obtaining an order, or enforcing an existing one, the agency has to keep the case open.
This is where custodial parents often lose ground. Notices land at old addresses or get mistaken for junk mail. If the 60 days pass and the case closes, you can reapply to reopen it, but the process restarts and there is usually a gap in enforcement in between. Keep your address current with the agency, and treat its mail as urgent.
Arrears and Interest Keep Running
Closure does not forgive a dollar of unpaid child support. Arrears remain a legally enforceable debt. There is no federal statute of limitations on child support arrears, and most states allow collection well past the child’s 18th birthday.
Interest makes closed cases quietly expensive. Roughly two-thirds of states charge interest on unpaid balances, usually in the range of 4% to 12% a year, with some using variable rates tied to market indexes. A parent carrying $15,000 in arrears at a 10% rate is adding $1,500 a year in interest alone, with no one actively collecting. A handful of states do not charge interest at all, so the exact exposure depends on your jurisdiction.
Settlements for less than the full balance are possible, but they need court approval. Judges will not sign off on arrangements that harm the child’s interests, so lowball offers rarely clear unless the custodial parent agrees and the court finds the deal reasonable.
Enforcement Tools That Keep Working After Closure
When the IV-D agency winds down, the enforcement machinery it was running on your behalf slows down with it. Current-support wage garnishments get released. Automatic tax refund intercepts tied to the agency’s file stop. But the legal mechanisms themselves do not disappear. Some of them keep running on their own, and the custodial parent can still pursue the rest through private legal action.
Passport Denial
A parent who owes more than $2,500 in past-due child support can be denied a U.S. passport, or have an existing one revoked or restricted.2Office of the Law Revision Counsel. 42 U.S. Code 652 – Duties of Secretary The state agency certifies the debt to the federal government, which notifies the State Department.3Administration for Children & Families. Passport Denial Program 101 If the certification was submitted before the case closed, the hold can stay in place until arrears drop below the threshold. People discover this years later when they apply for a passport and get denied.
Property Liens
Liens placed on a home, car, or other property for child support arrears do not disappear when the case closes. The lien stays attached until the debt is paid, which means the property cannot be sold or refinanced without first clearing the arrears or negotiating a release.
License Suspensions
Most states can suspend a delinquent parent’s driver’s license, professional license, or recreational license for nonpayment. Suspensions generally stay in effect until the parent pays in full or sets up a court-approved payment plan, and reinstatement often requires a fee to the licensing agency on top of catching up. The suspension does not lift automatically because the IV-D case closed.
Credit Reporting
Federal law requires every state to report delinquent child support to consumer credit agencies, with the parent’s name and the amount owed.4Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement Once reported, the delinquency can drag down a credit score and complicate mortgages, car loans, and other borrowing long after the case closes. The negative mark stays until the debt is resolved.
Wage Garnishment and Benefit Offsets
Federal law caps how much of a worker’s disposable earnings can be garnished for child support: 50% if the paying parent is supporting another spouse or child, 60% otherwise, with an extra 5% added when payments are more than 12 weeks overdue.5U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act After closure, a custodial parent can go to court independently and obtain a new income withholding order, though the agency will not do it automatically.
Social Security retirement and disability benefits can also be garnished for child support arrears.6Social Security Administration. Can My Social Security Benefits Be Garnished or Levied Federal employees can face salary offsets of up to 15% of disposable pay per period for overdue debts, including child support.7eCFR. 20 CFR 422.829 – Federal Salary Offset Being on a fixed income or working for the government does not shield a parent from collection.
Federal Tax Refund Offset
While a IV-D case is active, the agency automatically submits past-due balances to the Federal Tax Refund Offset Program, which intercepts the parent’s federal refund.8Administration for Children & Families. When Is a Child Support Case Eligible for the Federal Tax Refund Offset Program Once the case closes, that automatic submission generally stops, so this is one tool that largely goes quiet with the agency’s exit.
Federal Criminal Exposure Only Applies Interstate
Willfully failing to pay child support can be a federal crime, but only when the child and the paying parent live in different states. If both are in the same state, federal prosecution does not apply and any criminal exposure runs through state law.
When the interstate element exists, the penalties under 18 U.S.C. ยง 228 are a misdemeanor for support more than a year overdue or exceeding $5,000, carrying up to six months in prison, and a felony for support more than two years overdue or exceeding $10,000, carrying up to two years.9Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations Federal prosecutions are uncommon compared to state enforcement, but they do happen in cases involving large arrears and clear ability to pay.
When Support Doesn’t End at 18
A case may stay open past the child’s 18th birthday because many states extend the support obligation. Common extensions cover children still in high school at 18, children with disabilities that prevent self-support, and children enrolled full-time in college or vocational school. Post-secondary support can run until the child is anywhere from 19 to 23, depending on the state.
Some parents also include college support in their agreement voluntarily, and in several states a court can order it even over a parent’s objection. If your child is approaching 18, do not assume the obligation ends on that birthday. Check what your state allows and read the existing order, which may already contain language that keeps support going.
Reopening the Case or Going to Court Yourself
Closure is not necessarily permanent. Either parent can ask the IV-D agency to reopen the case by filing a new application for services. That is the fastest route back to the agency’s enforcement tools, useful when, for example, the noncustodial parent was previously unfindable and you now have a current address.
Changing the amount of support is a different step. You file a petition with the court that issued the original order and show a substantial change in circumstances, such as a significant income change, a job loss, a serious illness, or a meaningful change in the child’s needs. Filing fees for modification petitions are generally modest, and some jurisdictions waive them for low-income parents.
If the agency closed your case but arrears are still outstanding, you can hire a private attorney to pursue collection directly. It costs more than going through IV-D, but it gives you control and often moves faster. The unpaid support is a judgment debt, and an attorney can use the full range of remedies, including garnishment, liens, and contempt motions, without waiting on the agency.
If you are the custodial parent and you receive a closure notice, read it carefully and respond within 60 days if you disagree. Share any updated information about the other parent’s location, employment, or assets, and ask in writing that the case stay open if arrears are still owed.1eCFR. 45 CFR 303.11 – Case Closure Criteria If you are the paying parent, do not read closure as a release. The debt remains, interest may still be building, and the other side can come after you at any time. Closure can actually be a sensible moment to approach the custodial parent about a payment plan or settlement, since both sides have reason to resolve things before enforcement restarts. Any agreement needs court approval to bind either of you.
