Back child support in Alabama is the unpaid balance of court-ordered child support, called arrears, and it accrues statutory interest of 7.5% per year on orders entered on or after September 1, 2011. Each missed payment becomes a final money judgment on its due date, remains collectible for 20 years, and survives even after the child turns 19. This 2026 guide explains how Alabama calculates, enforces, and sometimes reduces past due child support.
This guide covers how arrears accumulate, the interest rates that apply, the enforcement tools the Alabama Department of Human Resources (DHR) can deploy, and the narrow path to forgiving interest under Ala. Code § 30-3-6.1. Written for both custodial parents owed support and non-custodial parents who owe child support debt, it draws on Alabama's controlling statutes and Rule 32 of the Alabama Rules of Judicial Administration.

What Is Back Child Support in Alabama?
Back child support in Alabama is the cumulative unpaid balance of a court-ordered support obligation, legally termed child support arrears. Under Alabama law, each individual payment that a non-custodial parent fails to make automatically converts into a final money judgment on its due date. This means arrears are not a single negotiable debt but a stacked series of enforceable judgments, each carrying its own interest start date.
Alabama treats past due child support far more aggressively than ordinary consumer debt. Because every missed installment becomes a vested judgment, courts cannot retroactively forgive or reduce the principal once it accrues. A custodial parent who is owed child support debt holds a legally protected property right in those payments. The obligation flows from the original support order entered under Rule 32 of the Alabama Rules of Judicial Administration, which sets the presumptive amount based on both parents' combined adjusted gross income. When that ordered amount goes unpaid, the resulting child support arrears remain fully collectible for two decades.
How Much Interest Accrues on Past Due Child Support?
Interest on back child support in Alabama accrues at 7.5% per year for support orders entered on or after September 1, 2011, under Ala. Code § 8-8-10. Orders entered between November 13, 1981 and August 31, 2011 still accrue interest at the older rate of 12% per year, and the rare pre-1981 judgments accrue at 6%. The applicable rate is fixed by when the order was entered, not when the missed payment occurred.
This tiered system produces dramatically different outcomes depending on the order's age. A parent who owes child support under a 2008 order pays 12% annual interest on arrears, while a parent under a 2015 order pays 7.5%. Alabama calculates interest on each individual missed payment from its specific due date, not on the total running balance. Because of this payment-by-payment method, a parent who falls years behind can watch the interest component swell well past the original principal. The 2011 amendment that lowered the rate to 7.5% was forward-looking only and did not reduce interest on any judgment entered before September 1, 2011.
How Partial Payments Apply to Child Support Debt
When a parent makes a partial payment toward back child support in Alabama, the payment is applied first to principal and then to any remaining interest. The Alabama Court of Civil Appeals confirmed this rule in T.L.D. v. C.G. (2002), reversing the ordinary debt-repayment convention used for credit cards and loans. This pro-parent ordering means voluntary partial payments reduce the underlying judgment balance faster than they would under standard accounting.
This matters because reducing principal first slows future interest accrual. Under a typical loan, payments hit interest first, keeping the principal high and interest compounding. Alabama's reverse approach gives non-custodial parents a meaningful incentive to make partial payments on child support arrears even when they cannot pay the full amount. Over a multi-year repayment period, applying funds to principal first can save a paying parent thousands of dollars in interest. Both custodial and non-custodial parents should track each payment carefully, because the correct application order directly affects the final payoff figure on the past due child support balance.
How Long Can Back Child Support Be Collected in Alabama?
Back child support in Alabama can be collected for 20 years from the date each individual payment became due. Because every missed installment becomes its own judgment with its own 20-year clock, the practical enforcement window extends well past the child's 19th birthday. A custodial parent can pursue child support arrears that came due when a now-adult child was a toddler, as long as fewer than 20 years have passed for that specific payment.
This lengthy statute of limitations distinguishes Alabama from states with shorter windows. The 20-year period applies to obtaining an order of support and to enforcing accrued arrears. Critically, child support debt does not expire simply because the child reaches the age of majority at 19. A parent who accumulated tens of thousands of dollars in past due child support over a decade remains fully liable, and the custodial parent retains the legal right to collect through any available enforcement mechanism. Each payment's individual due date controls, so the oldest arrears expire first while more recent unpaid amounts stay collectible. Parents owed support should calculate the limitations period payment by payment rather than from a single date.
How Alabama Enforces Back Child Support
Alabama enforces back child support through the Department of Human Resources (DHR) Child Support Enforcement Division, which can deploy income withholding, tax intercepts, license suspension, liens, and contempt of court. Enforcement typically begins within 30 to 60 days of a missed payment. The most common and effective tool is an income withholding order, which directs the non-custodial parent's employer to deduct child support directly from wages before the parent receives a paycheck.
Beyond wage garnishment, Alabama provides a wide arsenal against parents who owe child support. The state can intercept federal and state tax refunds, seize state lottery winnings, file liens against real and personal property, and deny passport applications. DHR can suspend driver's licenses, professional licenses, and even hunting and fishing licenses for non-payment. These administrative remedies operate without requiring a new court hearing in many cases, making them swift and powerful tools for collecting child support arrears across the state.
Credit Reporting and Tax Refund Intercepts
Alabama automatically reports back child support to credit bureaus once arrears exceed $1,000, and the negative entry remains on the parent's credit file for 7 years under federal credit law. For tax refund intercepts, the threshold is $150 in arrears if the child receives TANF benefits and $500 if the child does not receive public assistance. Once the past due child support balance reaches zero, the credit bureaus are notified and the account is reported as paid.
These reporting and intercept programs operate continuously and require no separate enforcement filing. The federal Treasury Offset Program and the Alabama Department of Revenue both feed refund data to DHR, which then redirects the intercepted funds to the family or, where public assistance was paid, to the state. A non-custodial parent who owes more than $1,000 will likely see a measurable drop in their credit score, affecting their ability to obtain loans, housing, or favorable interest rates. Because the 7-year reporting window runs even after the child support debt is satisfied, the credit consequences of falling behind extend long past the actual repayment.
Contempt of Court for Unpaid Child Support
A custodial parent can file a contempt of court action when the other parent willfully refuses to pay back child support in Alabama, and a finding of contempt can result in fines, jail time, or both. Parents who fall 30 days or more behind should consult an attorney promptly. To pursue enforcement directly through the court rather than waiting on DHR, a parent files a Request for Contempt Hearing using Form PS-03 from the Alabama Courts website.
Contempt is reserved for willful non-payment, meaning the court must find the parent had the ability to pay child support and chose not to. A parent who genuinely cannot pay because of job loss or disability is generally not held in contempt, though the underlying arrears continue to accrue. A judge who finds contempt can enter a judgment for the full past due child support amount, order a purge payment to avoid jail, and impose a coercive sentence until the parent complies. Intentionally falsifying income on the Child Support Obligation Income Statement/Affidavit (Form CS-41) is itself contempt of court under Rule 32. This makes accurate financial disclosure essential in every Alabama child support arrears proceeding.
Can You Reduce or Forgive Back Child Support in Alabama?
Alabama cannot forgive the principal of back child support, but Ala. Code § 30-3-6.1 allows a court to rebate accrued interest if the paying parent has paid the past due amount and stayed current for 12 consecutive months. Alternatively, a parent who entered a repayment agreement, honored it for at least 12 months, and paid current support for 12 months may petition for an interest rebate. The receiving parent must agree in writing to the rebate and its amount.
This interest-rebate provision is the only statutory avenue for reducing a child support debt, and it is deliberately narrow. The principal arrears can never be retroactively reduced because each payment vested as a judgment when it came due. The rebate reaches only the interest component, which can nonetheless be substantial given Alabama's 7.5% to 12% rates. The statute applies to all child support orders entered before and after August 1, 2004. Importantly, a court may reinstate any rebated interest if the parent is later found in contempt for failing to pay child support. Because the custodial parent holds a veto through the written-consent requirement, an interest rebate typically arises only as part of a negotiated settlement of the full past due child support balance.
When Does Child Support End in Alabama?
Child support in Alabama ends when the child reaches the age of majority at 19 under Ala. Code § 26-1-1, or earlier if the child becomes emancipated through marriage, military enlistment, or full economic independence. Reaching age 19 ends the future support obligation, but it does not erase any back child support that accrued before that date. Existing arrears remain fully collectible for 20 years regardless of the child's age.
A critical distinction exists between the legal basis for support ending and payments actually stopping. Where a wage withholding order is in place, the employer continues deducting child support until the court or DHR formally directs it to stop, so a paying parent must take affirmative steps to terminate the order. Support can extend past 19 in two narrow situations: a child with special needs whose parent petitions the court before the child turns 19, or a child still enrolled in high school and living with a parent. Alabama abolished post-minority college support in 2013 when the Supreme Court overruled Ex parte Bayliss in Ex parte Christopher, holding that courts cannot order parents to fund a child's college education. Any past due child support that accumulated before these cutoffs remains owed.
How to Calculate What You Owe in Back Child Support
To calculate back child support in Alabama, multiply each missed monthly payment by the number of months unpaid, then add interest at 7.5% or 12% accruing from each payment's individual due date. Because Alabama computes interest payment by payment rather than on a lump balance, the total owed grows progressively, and older missed payments carry more accumulated interest than recent ones. A custodial parent should request a certified arrears calculation from DHR or the circuit clerk.
Obtaining an accurate figure matters for both sides of a child support arrears dispute. The principal is fixed by the original Rule 32 order, but the interest component requires careful date-by-date computation. A parent who owes child support under a 2010 order, for example, pays 12% interest, while the same arrears under a 2014 order would accrue 7.5%. DHR maintains official payment records through the state disbursement unit, and these records serve as the authoritative source in any contempt or collection proceeding. Parents disputing the balance should compare DHR's ledger against their own payment receipts, because errors in crediting partial payments, which Alabama applies to principal first, can shift the final past due child support figure by thousands of dollars.
