Child Support Arrears: What Happens When You Fall Behind (2026)

Child support arrears accumulate whenever a non-custodial parent fails to make court-ordered child support payments on time and in full. Even missing a single payment creates arrears, and the balance grows with each missed or partial payment. Unlike many other forms of debt, child support arrears carry severe legal consequences and cannot be eliminated through bankruptcy.

There are two distinct types of child support arrears, and understanding the difference is critical because it affects your options for repayment and negotiation:

• Assigned arrears (owed to the state) — When the custodial parent receives public assistance such as Temporary Assistance for Needy Families (TANF), the right to collect child support is "assigned" to the state. The state then seeks reimbursement from the non-custodial parent. Because these arrears are owed to a government entity, some states offer compromise or amnesty programs that allow partial forgiveness.
• Unassigned arrears (owed to the custodial parent) — These are owed directly to the custodial parent and represent money that should have been used for the child's care. Courts are generally reluctant to reduce or forgive unassigned arrears without the custodial parent's agreement, since doing so would effectively take money from the child.

Arrears begin accumulating from the date specified in the court order. In many states, support obligations can also be retroactive to the date the petition was filed, meaning arrears can exist before a final order is even entered. Once established, the balance is treated as a judgment and can be enforced using all available collection tools.

Many states charge interest on unpaid child support arrears, which can cause the total balance to grow substantially over time. Interest rates vary significantly from state to state, and some states compound interest while others apply simple interest. Understanding your state's interest policy is essential for evaluating the true cost of falling behind.

For example, if you owe $10,000 in arrears in California, you would accrue $1,000 in interest per year at the 10% rate. Over five years without payments, that $10,000 balance could grow to $15,000 or more. In states that compound interest, the growth can be even more dramatic. Some states, such as Colorado and Oregon, do not charge interest on child support arrears, though the underlying balance remains fully enforceable.

Federal and state governments have an extensive arsenal of enforcement tools to collect child support arrears. These measures are among the most aggressive debt collection mechanisms available under law. Here is a comprehensive list of actions that may be taken:

Enforcement actions often escalate over time. A parent who falls slightly behind may first receive a notice, followed by automatic wage withholding. As the arrears grow, more aggressive measures such as license suspension and tax intercepts come into play. If you have fallen significantly behind, you may want to learn about how far behind in child support before a warrant is issued.

Whether child support arrears can be forgiven depends primarily on who the arrears are owed to. The rules differ significantly between state-owed and custodial-parent-owed arrears.

Arrears Owed to the State (Assigned Arrears)

When arrears have been assigned to the state because the custodial parent received TANF or other public assistance, some states offer debt compromise programs. These programs allow the non-custodial parent to negotiate a reduced payoff amount, typically requiring a lump-sum payment. States benefit from these programs because collecting a portion of the debt is better than collecting nothing, and reducing the burden on the non-custodial parent makes it more likely they will stay current on ongoing obligations.

Arrears Owed to the Custodial Parent (Unassigned Arrears)

Arrears owed directly to the custodial parent are much harder to reduce. Courts generally will not forgive or reduce these arrears without the custodial parent's consent, as the money belongs to the child and the custodial parent. In some cases, the custodial parent may agree to a negotiated settlement, but this must be approved by the court. The custodial parent has no legal obligation to accept less than the full amount owed.

State Compromise and Amnesty Programs

Several states periodically offer amnesty or compromise programs designed to reduce arrears balances. These programs typically require the non-custodial parent to be current on ongoing support, make a lump-sum payment toward arrears, and maintain consistent payments going forward. States like California, Texas, and Illinois have offered such programs. Eligibility requirements and program availability change frequently, so check with your state's child support agency for current options.

Child support arrears are classified as "priority debts" in bankruptcy, meaning they receive the highest level of protection. In a Chapter 13 repayment plan, all child support arrears must be paid in full over the life of the plan before any unsecured creditors (such as credit card companies) receive payment. Filing bankruptcy may actually make it easier to pay off child support arrears by eliminating other debts, but the child support obligation itself will survive the bankruptcy in full.

Additionally, automatic stay protections in bankruptcy do not apply to child support enforcement actions. This means wage garnishment for child support, contempt proceedings, and license suspension can continue even while a bankruptcy case is pending.

While eliminating child support arrears entirely is rarely possible, there are legitimate strategies for reducing the balance or managing the obligation more effectively:

A common misconception is that child support arrears disappear when the child turns 18 or reaches the age of majority. This is not the case. Child support arrears are a debt that remains legally enforceable regardless of the child's age. Here is what you need to know:

• The debt survives — Arrears that accumulated while the child was a minor remain owed in full. The obligation to pay ongoing support may end, but the back balance does not.
• Enforcement continues — All enforcement tools remain available, including wage garnishment, tax refund intercepts, liens, and license suspensions. The state child support agency continues to collect on behalf of the custodial parent.
• Statutes of limitations vary — Some states impose a statute of limitations on collecting arrears (commonly 10 to 20 years after the child reaches the age of majority), while others have no time limit at all. In states without a statute of limitations, arrears can be enforced indefinitely.
• Interest continues to accrue — In states that charge interest on arrears, interest typically continues to accrue on the unpaid balance even after the child turns 18.

Because arrears persist beyond the child's minority, it is critical to address them as early as possible. The longer arrears remain unpaid, the more they grow (through interest) and the more enforcement actions accumulate.
