Yes. In almost every situation you can still collect back child support, and unpaid support (called "arrears") usually does not simply disappear. Once a payment is missed and becomes past due, it generally hardens into a money judgment the other parent owes you. Federal law goes a step further: support that has already come due cannot be retroactively wiped out or reduced, even by a judge. The harder questions are how long you have to collect under your state's rules, who is legally owed the money, and how to clean up a credit report once the debt is paid or disputed.
What "arrears" are—and why they're hard to erase
Arrears are the running total of court-ordered child support payments that were due but never paid, often with interest added under state law. Each missed installment typically becomes a vested judgment on the date it was due.
The key federal protection is the Bradley Amendment (42 U.S.C. § 666(a)(9)(C)). It bars states from retroactively modifying support that has already accrued. In plain terms: a parent who fell behind cannot go to court later and ask a judge to forgive or shrink the back balance. A modification can only change payments going forward—and only back to the date the modification motion was filed or served (which of the two controls varies by state). This is why "Can you modify child support arrears?" almost always gets the answer no for amounts already past due, even if the paying parent lost a job or was incarcerated.
There are narrow real-world exceptions worth knowing: arrears the custodial parent personally is owed can sometimes be voluntarily forgiven or compromised by that parent (states differ, and arrears assigned to the state for public-assistance reimbursement usually can't be waived by you). And clerical or accounting errors in the state's ledger can always be corrected—that's fixing a mistake, not modifying the obligation.
Can you collect back child support as an adult or after the child grows up?
This is one of the most-searched and most-misunderstood questions. Two different scenarios get tangled together:
You are the parent who was owed support. The right to collect arrears belongs to the obligee—the parent (or the state, if it paid public assistance) to whom the support was ordered. That right does not vanish the day your child turns 18 or graduates. The current support obligation ends at emancipation, but the accumulated arrears remain a collectible judgment. So yes, a parent can pursue years-old back support after the child is grown, subject to the state's time limits.
You are the now-adult child. Generally the grown child is not the proper party to collect the back support—the debt was legally owed to your custodial parent or to the state, not to you. A handful of states have limited mechanisms, but you should not assume you can sue your other parent directly for support that was meant for your childhood. Talk to a lawyer or your state child-support agency about who actually holds the claim.
Statutes of limitation: the time-sensitive part
This is where state law varies the most, so check your own state's rule before assuming you've waited too long. There is no single national deadline. In practice:
Some states impose no statute of limitations on enforcing child-support arrears at all.
Many states give a long window—commonly measured as a number of years after the child emancipates or after the last payment was due—often in the 10-to-20-year range, but the exact number and trigger differ.
Even where a limit exists, renewing or docketing the judgment before it lapses can extend your ability to collect.
Because the clock and the trigger date differ so much, the practical move is to act promptly and ask your state IV-D child-support agency or a lawyer to confirm your deadline in writing.
How back support actually gets collected
Federal law (Title IV-D of the Social Security Act) requires every state to run a child-support enforcement agency and to keep specific collection tools on the books (42 U.S.C. §§ 654, 666). When you open or reopen an enforcement case, these are the levers:

Income withholding. Garnishing wages is the workhorse tool and is mandated under 42 U.S.C. § 666(a)(1). An order can withhold for current support plus an extra amount applied to the arrears.
Tax-refund offset. Past-due support can be intercepted from federal (and state) tax refunds. The federal refund offset is authorized under 42 U.S.C. § 664, run through the state agency and the federal Treasury Offset Program.
Liens. States must allow liens against real and personal property for overdue support (42 U.S.C. § 666(a)(4)), which can attach to houses, cars, or bank accounts.
License suspension. Driver's, professional, and recreational licenses can be suspended for nonpayment (42 U.S.C. § 666(a)(16)).
Federal pay and benefits. The U.S. government waives its immunity so that federal wages and many federal benefits can be garnished for support (42 U.S.C. § 659)—including military pay.
Passport denial and credit reporting of large arrears are also standard enforcement consequences administered through the federal-state system.
When the other parent lives in a different state
You do not lose your rights because the other parent moved away. Under the federal Full Faith and Credit for Child Support Orders Act (28 U.S.C. § 1738B) every state must enforce another state's support order according to its terms and may not modify it except under narrow continuing-jurisdiction rules. This works hand-in-hand with the Uniform Interstate Family Support Act (UIFSA), which all states have adopted, to register and enforce your order across state lines—often without you having to travel.
Can the debt be erased in bankruptcy?
No. Child support is a "domestic support obligation" that cannot be discharged in bankruptcy (11 U.S.C. § 523(a)(5)), and it is paid first among unsecured claims (11 U.S.C. § 507(a)(1)). If the other parent files bankruptcy, your back support survives it.
Can you get child support off your credit report?
Past-due child support reported by a state agency can appear as a negative item on your credit file. Whether and how you can remove it depends on whether the entry is inaccurate or simply unpaid:
If the entry is wrong—incorrect balance, debt that was actually paid, wrong dates, or it isn't your debt—you can dispute it with each credit bureau (Equifax, Experian, TransUnion). Federal consumer-credit law requires the bureau to investigate and correct or delete information it cannot verify. Send your dispute in writing and attach your payment records and the agency's arrears ledger.
If the debt is accurate and unpaid, the most reliable fix is to resolve it: pay it off or enter a payment plan with the child-support agency, then ask the agency to report the updated zero or paid status. Accurate negative information can lawfully remain for a period of years, but a paid or corrected balance looks far better than an open arrears judgment.
Get the agency's ledger first. Request an official payment history from your state child-support office so your dispute and your records match the government's numbers.
Be cautious with companies that promise to "delete" legitimate child-support debt from your credit for a fee—you can dispute inaccuracies yourself for free, and a real, owed debt generally can't simply be scrubbed.
What you can do
Open or reopen a case with your state's IV-D child-support enforcement agency. Their services are low-cost or free and unlock wage withholding, tax-refund offset, liens, and interstate enforcement.
Get the numbers in writing. Ask for an official arrears calculation and full payment ledger, including any state-law interest. You'll need this for court and for any credit dispute.
Confirm your deadline. Ask the agency or a lawyer—in writing—what your state's statute of limitations is and whether you must renew or docket the judgment to keep it alive.
Don't expect arrears to be reduced. Already-accrued support generally can't be lowered (Bradley Amendment). If you're the one behind, file any modification request immediately, because relief only runs from the filing/service date forward.
Fix your credit file. Dispute inaccurate entries with all three bureaus using your payment records; for accurate debts, resolve the balance and ask the agency to report the update.
Consider a lawyer when arrears are large. A high back-balance often justifies hiring a family-law attorney—liens, judgment renewal, contempt actions, and interstate registration can substantially increase what you actually recover.
Bottom line
Back child support is real, enforceable money. Arrears typically survive the child's adulthood, survive a move to another state, and survive the other parent's bankruptcy, and they usually cannot be retroactively forgiven. Your most time-sensitive risk is your state's statute of limitations and the need to renew the judgment—so act sooner rather than later.

Frequently asked questions
Can I get back child support after my child turns 18?
Generally yes if you are the parent who was owed the support. Current support ends at emancipation, but accumulated arrears remain a collectible judgment afterward, subject to your state's statute of limitations. A now-adult child, however, usually is not the proper party to collect—the debt was legally owed to the custodial parent or the state.
Can child support arrears be reduced or forgiven?
Support that has already come due generally cannot be retroactively reduced because of the federal Bradley Amendment. A modification only changes future payments and reaches back only to the date the motion was filed or served. The custodial parent can sometimes voluntarily compromise arrears owed personally to them, but arrears assigned to the state usually cannot be waived.
How do I get child support off my credit report?
If the entry is inaccurate—wrong balance, already paid, or not yours—dispute it in writing with Equifax, Experian, and TransUnion and attach your payment records and the agency's ledger; bureaus must investigate. If the debt is accurate and unpaid, pay it or set up a plan, then ask the child-support agency to report the updated paid or zero balance.
Can the other parent erase back child support by filing bankruptcy?
No. Child support is a domestic support obligation that cannot be discharged in bankruptcy (11 U.S.C. 523(a)(5)) and is actually paid first among unsecured claims (11 U.S.C. 507(a)(1)). Your back support survives the other parent's bankruptcy.
What if the parent who owes me moved to another state?
You can still collect. Under the Full Faith and Credit for Child Support Orders Act (28 U.S.C. 1738B) and the Uniform Interstate Family Support Act (UIFSA), every state must enforce another state's order and your state agency can register and enforce it across state lines—often without you having to travel.
