What Is Back Child Support in Delaware?
Back child support in Delaware is the accumulated total of court-ordered child support payments that an obligor parent failed to pay when due. These unpaid amounts are legally called arrears, and Delaware treats each missed payment as a fixed debt the moment it becomes due. Under Del. Code tit. 13 § 513, the Family Court retains continuing jurisdiction to enforce a support order — including orders issued before March 31, 1987 — for as long as arrearages or past-due amounts remain owing. Delaware imposes no statute of limitations on collecting child support debt, meaning a custodial parent can pursue past due child support years or even decades after the payments were missed. This makes Delaware one of the more aggressive states for arrears enforcement, and the obligation does not disappear when a child turns 18.
Back child support differs from retroactive support. Retroactive support is an amount the court orders to cover the period before a support order existed, while arrears are missed payments under an order already in place. Both are enforceable debts.
Is There a Statute of Limitations on Back Child Support in Delaware?
Delaware has no statute of limitations on collecting back child support, so arrears remain enforceable indefinitely regardless of how much time has passed. A custodial parent or the Division of Child Support Services (DCSS) may pursue past due child support 10, 20, or more years after the payments were missed, and the death of the obligor does not automatically extinguish the debt against the estate.
This is a critical distinction from ordinary civil debts, which Delaware time-bars after a fixed period. Child support arrears are exempt from those limits because Delaware law and federal mandates under 42 U.S.C. § 666 treat each unpaid installment as a final judgment by operation of law. Once support becomes due and goes unpaid, it converts into an enforceable money judgment without any further court action. Under Del. Code tit. 13 § 513, the Family Court keeps jurisdiction over the debt until the balance reaches zero. Practically, this means a parent who owes child support debt cannot simply wait out the obligation; the arrears will follow them, attach to tax refunds, and remain collectible through enforcement tools described below.
How Far Back Can Delaware Order Retroactive Child Support?
In a new Delaware support petition, the Family Court presumes six months of retroactive support before the filing date and may order up to a maximum of two years, per Family Court Form 509i and Del. Code tit. 13 § 513. In a modification petition, retroactivity cannot reach further back than three days after the summons is mailed.
These retroactivity caps shape how much a parent can be ordered to pay for the period before an order existed. When a custodial parent files a brand-new petition, the court assumes the noncustodial parent owed support for the six months preceding filing. Either party may present evidence to argue for more or less retroactive support, but the award cannot exceed two years of back support. The two-year ceiling protects obligors from open-ended retroactive liability while still recognizing that children needed support before the paperwork was filed. For modification cases, the rule is far stricter: a change to an existing order applies only from three days after the summons mailing date, preventing parties from reaching back to recover or reduce amounts from earlier periods. These rules govern retroactive support specifically, not arrears, which accrue under an existing order and carry no time limit.
How Does Delaware Calculate Child Support and Arrears?
Delaware calculates child support using the Melson Formula, a variation of the income shares model that first reserves a self-support amount for each parent, then allocates the child's primary needs, then applies a standard-of-living adjustment. Arrears equal the sum of all unpaid installments under the order; the Family Court adds each missed amount to the running balance until the obligor pays in full.
The Melson Formula is used by only a few states and is named after Delaware Family Court Judge Elwood F. Melson Jr. It is built on the principle that a child's basic needs come first, while ensuring both parents retain a minimum income for their own necessities through a self-support reserve. When an obligor falls behind, the DCSS records each unpaid installment, and under Del. Code tit. 13 § 2215, the records of the Division are presumptive evidence of the amount in arrears and of the obligor's payment history at any enforcement hearing. Delaware does not routinely charge interest on most adjudicated arrears, though sanctions in contempt proceedings can add amounts. The full principal balance remains collectible without time limit.
How Does Delaware Enforce Back Child Support?
Delaware enforces back child support through the Division of Child Support Services using wage attachment, license suspension at $1,000 in arrears under Del. Code tit. 13 § 516, passport denial at $2,500, lottery intercept, tax refund offset, credit bureau reporting at $500 behind, and contempt proceedings that can result in jail. Wage attachment is the most common remedy and requires no separate arrears petition.
Delaware deploys one of the broadest enforcement toolkits in the country. Income withholding orders direct an employer to deduct support directly from wages, and under Del. Code tit. 13 § 513, income is attached automatically when an obligor defaults for one calendar month and no withholding order is in effect. The DCSS layers on administrative remedies that escalate with the size of the child support debt. The table below summarizes the key enforcement triggers and their arrears thresholds as of 2026.
| Enforcement Action | Arrears Threshold | Authority |
|---|---|---|
| Wage / income attachment | 1 month default | § 513 |
| Credit bureau reporting | $500 behind | DCSS policy |
| Driver / professional license suspension | $1,000 (§ 516) / $3,500 (DCSS admin) | § 516 |
| Passport denial | $2,500 past due | Federal (42 U.S.C. § 652) |
| Lottery / tax intercept | Any arrears | Chapter 22 |
| Contempt / incarceration | Willful nonpayment | § 516 |
License Suspension for Child Support Arrears in Delaware
Delaware Family Court may suspend a parent's licenses when the obligor owes $1,000 or more in arrears or retroactive support, is at least 30 days delinquent, and the failure to pay is willful and not due to inability to pay, under Del. Code tit. 13 § 516. The DCSS separately uses a $3,500 administrative threshold for license actions where no complete payment has been made in 60 days.
License suspension is among Delaware's most effective enforcement tools because it affects daily life and earning capacity. The DCSS can suspend Delaware driver licenses, hunting and fishing licenses, and occupational and professional licenses. Two distinct pathways exist: the judicial route under § 516 requires a court finding of willful nonpayment at the $1,000 level, while the administrative route applies when an obligor owes $3,500 or more and has made no complete ordered payment in the past 60 days. Before suspension, the noncustodial parent receives notice and an opportunity for a hearing. A parent who genuinely cannot pay — for example, due to job loss or disability — has a defense, because the statute requires willfulness. Reinstatement typically requires paying the arrears or entering a payment arrangement with DCSS.
Passport Denial and Federal Enforcement of Back Child Support
The U.S. State Department denies passports to any noncustodial parent who owes $2,500 or more in past-due child support, and Delaware certifies qualifying cases to the federal Office of Child Support Services. This is a federal threshold set by the Deficit Reduction Act of 2005, applied uniformly across all states including Delaware.
Passport denial is triggered through the Federal Collections and Enforcement Program, which links state child support agencies with the State Department's Consular Lookout and Support System (CLASS). When a Delaware obligor's child support debt reaches $2,500, the DCSS sends a notice informing the parent of noncompliance. Within 30 days, the obligor may pay the arrears in full or request a written administrative hearing; those who do neither face passport denial. A crucial caveat catches many parents off guard: the obligor is not automatically removed from the program when arrears drop below $2,500. Removal requires either that Delaware specifically request it or that the support debt be reduced to zero. Federal enforcement also includes intercepting federal tax refunds and certain federal benefit payments to satisfy past due child support, making it difficult to evade arrears by relocating out of state.
How Do You Collect Back Child Support in Delaware?
To collect back child support in Delaware, a custodial parent applies for free DCSS enforcement services or files an arrears petition with Family Court for a $175 fee. The DCSS then pursues wage attachment, tax intercepts, license suspension, and other remedies; under Del. Code tit. 13 § 2215, agency records serve as presumptive proof of the amount owed.
The most accessible path is opening a case with the Division of Child Support Services, which charges no fee for enforcement and has direct access to federal and state interception systems. A custodial parent submits an application with supporting documents by mail or in person at any DCSS office. Alternatively, a parent may file a petition for arrears directly with Family Court, paying the $175 filing fee ($165 petition fee plus $10 court security assessment), with a fee waiver available through an Affidavit to Proceed In Forma Pauperis for those who cannot afford it. At the arrears hearing, the court can add a repayment amount to the order. Under Family Court Rule of Civil Procedure 509(d), the presumptive arrears repayment is the greater of $20 per month or 20% of the current support obligation, and when current support ends, repayment continues at roughly the prior support amount until the balance clears.
What Happens If You Cannot Pay Back Child Support in Delaware?
If you cannot pay back child support in Delaware, you should file a petition to modify the order rather than ignore it, because Del. Code tit. 13 § 516 only sanctions willful nonpayment. After 2.5 years from the last order, you can modify without proving changed circumstances; within that window, you must show a substantial change such as job loss.
Nonpayment due to genuine inability is a recognized defense in Delaware enforcement proceedings, but it must be raised proactively. A parent who loses a job, becomes disabled, or suffers a major income drop should immediately petition the Family Court to modify the current support obligation, since modification cannot retroactively erase arrears that already accrued. Delaware's 2.5-year rule allows modification without demonstrating changed circumstances once 30 months have passed since the last order; before that, the parent must prove a substantial and material change. Importantly, the 2.5-year particularity requirement also applies to petitions seeking to modify an arrears repayment schedule. Even a parent unable to pay the full amount should make partial payments and document the inability, because consistent good-faith effort weighs heavily against a contempt finding and possible incarceration under § 516.
