Back child support in Hawaii refers to court-ordered support payments that an obligor parent failed to pay when due, which then accumulate as a legally enforceable debt called arrears. Under Haw. Rev. Stat. § 657-5.5, child support judgments and arrears in Hawaii are enforceable until paid in full, with no expiration date. Unlike most states, Hawaii charges zero interest on past due child support, but the Child Support Enforcement Agency (CSEA) wields aggressive collection tools including license suspension, tax intercepts, and passport denial.

What Counts as Back Child Support in Hawaii?
Back child support in Hawaii is the total of all court-ordered support payments an obligor failed to pay by their due dates, recorded as arrears by the Child Support Enforcement Agency. Each missed monthly payment converts into a vested money judgment the moment it becomes due. With the minimum obligation at $83 per month per child under the 2024 Hawaii Child Support Guidelines, even modest orders generate significant child support debt over time.
Hawaii law treats every installment of court-ordered support as a separate judgment that vests when it becomes due. Under Haw. Rev. Stat. § 576D-10, when an obligor defaults, the custodial parent notifies CSEA, and the agency proceeds against the obligor for the arrearage while retaining jurisdiction over all future payments. Arrears can be owed to the custodial parent directly, or to the State of Hawaii when the family received public assistance benefits on behalf of the children. This distinction matters enormously: arrears owed to the State cannot be forgiven by the custodial parent and require State agreement to discharge. The 2024 Child Support Guidelines, effective April 1, 2024, govern all calculations statewide and apply to the Family Court, CSEA, and the Office of Child Support Hearings.
Does Back Child Support Expire in Hawaii?
Back child support never expires in Hawaii. Under Haw. Rev. Stat. § 657-5.5, every judgment for child support — including reimbursement and arrears — remains enforceable until paid in full, with no statute of limitations cutoff. This 2026 rule supersedes older sources that cite a 10-year or "33rd birthday" deadline.
Many websites still repeat an outdated rule based on Haw. Rev. Stat. § 657-5, the domestic judgments statute, which presumes ordinary judgments paid and discharged 10 years after rendering. Because Hawaii case law applied the statute of limitations to each installment as it came due, the math produced an approximate cutoff around a child's 33rd birthday (10 years after the last payment owed at age 23 for a child in college). However, Haw. Rev. Stat. § 657-5.5 explicitly overrides this: "Notwithstanding section 657-5 and any other law to the contrary, every judgment for child support, including a judgment for reimbursement or other arrears, shall be enforceable until paid in full." CSEA confirms this current standard, stating plainly that in Hawaii, child support is enforceable until it is paid in full. A parent who owes child support debt cannot wait out the clock — there is no clock to wait out.
Does Hawaii Charge Interest on Past Due Child Support?
Hawaii does not charge interest on child support arrears. The State of Hawaii does not allow interest on judgments, missed payments, or retroactive support, making it one of the few states where past due child support does not compound over time. The arrears balance stays fixed at the principal owed.
This is a meaningful difference from states like Washington (12% annual interest) or Colorado (variable statutory rate), where a $10,000 arrears balance can balloon to $20,000 or more over a decade. In Hawaii, $10,000 in unpaid child support remains $10,000 regardless of how many years pass. While this benefits obligors facing child support debt, it does not weaken enforcement — CSEA simply relies on its extensive collection arsenal rather than accruing interest. The no-interest policy applies to all categories: regular monthly arrears, retroactive support orders, and reimbursement judgments owed to the State. Parents who owe child support should still resolve arrears promptly, because the collection tools (license suspension, liens, passport denial) escalate regardless of whether interest accrues. The fixed principal also makes negotiated payoffs and lump-sum settlements easier to calculate when working with CSEA.
How Does CSEA Enforce Back Child Support in Hawaii?
The Child Support Enforcement Agency enforces arrears through automatic income withholding, license suspension at 3 months delinquent, tax refund intercepts at $25 owed, property liens, credit bureau reporting, and passport denial at $2,500. Under Haw. Rev. Stat. § 576D-14, income withholding is automatic on all child support orders.
Income withholding is the primary mechanism. Under Haw. Rev. Stat. § 576E-16, whenever an order establishes, modifies, or enforces support — or establishes accrued arrearage — an income assignment issues concurrently, directing the obligor's employer to withhold support directly from wages. Employers may deduct a $2 administrative fee per payment and must comply or face liability. Beyond withholding, CSEA deploys layered enforcement: state tax refund intercepts under Haw. Rev. Stat. § 231-51 when arrears reach $25; federal tax refund intercepts and the Administrative Offset Program for federal payments; liens filed with the Bureau of Conveyances against real and personal property; credit bureau reporting under Haw. Rev. Stat. § 576D-6 after 14 days' notice; and passport denial for debts exceeding $2,500. CSEA policy requires a $0 balance before allowing passport issuance to anyone previously in arrears, even after the debt drops below the federal $2,500 threshold.
When Does Hawaii Suspend Licenses for Back Child Support?
Hawaii suspends driver's and recreational licenses when an obligor becomes delinquent by an amount equal to 3 months of child support payments under Haw. Rev. Stat. § 576D-13. Professional and vocational licenses face suspension at 6 months delinquent. Parents avoid suspension by entering a payment agreement with CSEA.
License suspension is among CSEA's most effective tools because it directly threatens an obligor's ability to work and earn the income needed to pay support. The process requires due process: upon determining noncompliance, CSEA must serve notice of intent to certify the obligor as noncompliant, which then directs the relevant licensing authority to deny, suspend, or refuse renewal of the license. The graduated structure escalates pressure — three months of missed payments triggers driver's and recreational (hunting, fishing) license action, while six months reaches professional credentials like medical, legal, real estate, and contractor licenses. Critically, the statute provides an off-ramp: an obligor who enters and maintains a payment agreement with CSEA avoids suspension entirely. This means a parent who owes child support and proactively negotiates a realistic payment plan can keep their license and their earning capacity intact, which serves both the obligor and the children who depend on continued payments.
Can You Reduce or Modify Back Child Support in Hawaii?
You cannot retroactively reduce child support arrears that already accrued in Hawaii. Courts modify support only prospectively — back to the date you file the modification request, never to the date your circumstances changed. Under Haw. Rev. Stat. § 580-47, either parent may petition for review once every three years without showing changed circumstances.
Hawaii follows the federal anti-retroactivity rule rooted in Smith v. Smith, 3 Haw. App. 170, 647 P.2d 722 (1982): court-ordered child support may be modified prospectively but not retroactively, except under Rule 60 of the Hawaii Family Court Rules. The practical lesson is urgent — if you lose your job or suffer a major income drop, file for modification immediately, because every day of delay locks in support at the old (higher) amount. A parent who waits six months to file accumulates six months of arrears at the original rate that no court can erase. Modifications require a material change in circumstances, most commonly a significant income increase or decrease. The Office of Child Support Hearings (OCSH) offers a no-cost administrative alternative to Family Court for modifications. Notably, under Haw. Rev. Stat. § 580-47, being in arrears does not bar a parent from requesting a modification hearing — owing back child support does not strip you of the right to seek a fair, current order.
Can Back Child Support Be Forgiven in Hawaii?
Back child support can be forgiven in Hawaii only when the arrears are owed to the custodial parent, not the State. The custodial parent and obligor submit a written stipulation to the court forgiving the debt, and courts generally approve it. Arrears owed to the State for public assistance require State agreement to discharge.
The distinction between privately-owed and State-owed arrears is decisive. If the past due child support is owed directly to the receiving parent, that parent has the legal power to forgive it. The two parents prepare a stipulation — a signed agreement stating the custodial parent forgives the arrears — and submit it to the Family Court for approval. Once approved, the custodial parent presents the order to CSEA to clear the agency's records. However, when a family received TANF or other public assistance, the State paid those benefits and is reimbursed from child support; arrears assigned to the State cannot be waived by the custodial parent because the debt is no longer theirs to forgive. Only the State of Hawaii can discharge State-owed arrears, and it does so sparingly. Obligors carrying mixed arrears (some owed to the parent, some to the State) may be able to reduce the private portion through stipulation while the State portion remains. This is why understanding who is owed each dollar of your child support debt is the first step in any payoff or forgiveness strategy.
How Do You Open a Back Child Support Case With CSEA?
You open a back child support case by applying for services with the Hawaii Child Support Enforcement Agency, which can establish paternity, obtain a support order, and collect arrears through an administrative process under Haw. Rev. Stat. ch. 576E. CSEA operates separately from the courts and charges no fee for parents seeking enforcement of owed child support.
CSEA, housed within the Hawaii Department of the Attorney General, has independent legal authority to establish and enforce support either administratively or through the courts. A custodial parent owed back child support applies for CSEA services; if the parents were never married, CSEA can first establish paternity. The agency then uses the administrative process, with hearings officers from the Office of Child Support Hearings (OCSH) issuing decisions on establishment, modification, termination, and enforcement statewide. This administrative track is faster and cheaper than Family Court litigation for many enforcement matters. For divorce-related child support, the underlying order originates in Family Court within the obligor's circuit — First Circuit (Oahu), Second Circuit (Maui County), Third Circuit (Hawaii Island), or Fifth Circuit (Kauai). The divorce filing fee with minor children is $265 as of March 2026 (which includes a $50 parent education surcharge funding the Kids First program), versus $215 without children. As of March 2026, verify current fees with your local Family Court clerk, as amounts change. CSEA enforcement services themselves carry no filing fee for the custodial parent.
