South Carolina back child support, also called child support arrears, is the total of past-due and unpaid support owed under a court or administrative order. South Carolina imposes no statute of limitations on collecting arrears and charges no interest on the balance, but enforcement is aggressive: license suspension begins at $500 owed, property liens attach automatically, and contempt carries up to one year in jail and a $1,500 fine under S.C. Code § 63-3-620.
This guide explains how past due child support is calculated, enforced, and collected in South Carolina, who can pursue it, and what options exist for parents who owe a child support debt. The South Carolina Department of Social Services (DSS) Child Support Services Division (CSSD) administers most enforcement under Title 63, Chapter 17 of the South Carolina Code.

What Is Back Child Support in South Carolina?
Back child support in South Carolina is the cumulative total of unpaid monthly support obligations that became due under a valid court or administrative order. Under S.C. Code § 63-17-720, "arrearage" means amounts of past-due and unpaid monthly support obligations established by a court or administrative order. The debt accrues automatically each month a payment is missed, with no requirement that the recipient file anything to preserve it.
South Carolina law distinguishes arrears from current support. Current support is the ongoing monthly obligation; arrears are the accumulated unpaid balance from prior months. Once a payment is missed, that amount becomes a fixed, vested debt. Under S.C. Code § 63-17-1600, the clerk of court records arrearages as they accrue. South Carolina treats each past-due installment as a judgment by operation of law, meaning the custodial parent does not need to return to court to convert missed payments into an enforceable obligation. This vested-judgment principle is why arrears cannot be retroactively erased and why the child support debt survives the child reaching adulthood.
How Long Can You Collect Back Child Support in South Carolina?
South Carolina has no statute of limitations on collecting back child support. Arrears remain collectible indefinitely — even after the child turns 18 or 19, even after the support order ends, and even decades later. The full balance of past due child support stays enforceable until paid in full, and South Carolina appellate courts have expressly held that statutes of limitation barring ordinary civil actions do not apply to child support or paternity claims.
This makes South Carolina one of the most recipient-favorable states for collecting a child support debt. In states with limitations periods, an obligor can sometimes outlast the collection window; in South Carolina, no such window exists. Either the custodial parent or the state, acting through DSS, may pursue the arrearage at any time. An adult child who was the beneficiary of support can in some circumstances pursue arrears that accrued during minority. Because the debt does not expire, a parent who accumulated thousands in arrears years ago can still face wage garnishment, tax intercepts, or contempt today. The practical consequence is that owing child support arrears in South Carolina is a permanent liability until the obligor satisfies the full amount the court records show is due.
Does South Carolina Charge Interest on Child Support Arrears?
South Carolina does not charge interest on child support arrears. Unlike many states that add statutory interest — often 6% to 12% annually — to overdue child support, retroactive support, or adjudicated arrears, South Carolina assesses 0% interest on the unpaid balance. The amount owed equals the sum of missed payments without any compounding or accrual on top.
This is a significant distinction for both sides. For obligors, the absence of interest means a child support debt does not balloon over time the way it would in interest-charging states; a $10,000 arrearage from five years ago is still $10,000, not $10,000 plus years of accrued interest. For recipients, it means the collectible amount is capped at the principal owed. However, the no-interest rule provides little comfort to obligors when combined with South Carolina's indefinite collection window — the debt never grows, but it also never goes away. Parents who owe child support sometimes assume late balances grow with penalties; in South Carolina, the principal is fixed, and the real pressure comes from enforcement tools rather than from accumulating interest charges.
How South Carolina Enforces Back Child Support
South Carolina deploys a broad arsenal of administrative and judicial enforcement tools through DSS Child Support Services, beginning at low arrears thresholds. Automatic wage withholding issues to an employer once an obligor is 30 days delinquent. State tax refunds are intercepted at $100 in arrears, federal refunds at $500 (non-TANF cases), and the U.S. State Department denies passports at $2,500. These mechanisms run largely without court hearings.
The enforcement ladder escalates with the size of the child support debt. Income withholding is governed by Article 11 of Chapter 17, and under S.C. Code § 63-17-1410 most support orders are subject to withholding. DSS also reports arrearages to credit bureaus under S.C. Code § 63-17-2510, damaging the obligor's credit and ability to secure loans or housing. Unemployment and workers' compensation benefits are subject to interception. Financial-institution data matches under S.C. Code § 63-17-2310 let the state locate and reach bank accounts. The combined effect is a system designed to collect past due child support through automated, escalating pressure on income, refunds, credit, and assets before a case ever reaches a contempt hearing.
License Suspension for Child Support Arrears
South Carolina suspends licenses when an obligor reaches $500 in child support arrears and has made no payment within 60 days. The state can suspend driver's licenses, professional licenses (including medical, legal, and contractor licenses), and recreational licenses such as hunting and fishing permits. The obligor receives 45 days' advance notice before any suspension takes effect.
During that 45-day notice period, the obligor can contact DSS Child Support Services and enter a payment agreement on the arrearage to prevent suspension. Once a license is suspended, it cannot be reinstated until the obligor reaches an agreement with CSSD to pay the past due child support. License suspension is among South Carolina's most effective tools because it directly threatens the obligor's ability to work and earn. Note that pending legislation, Senate Bill 652 (2025–2026 session), was introduced to repeal Article 7 of Chapter 17 and Section 56-1-171 governing driver's-license suspension for arrears; as of early 2026 the bill remained in the Senate and was not law. Until any repeal passes, the $500 suspension threshold and 45-day cure window remain in full effect for anyone who owes child support in South Carolina.
Child Support Liens and Asset Seizure
South Carolina automatically creates a child support arrearage lien against an obligor's property the moment arrears accrue, with no court order required. Under S.C. Code § 63-17-2710, once recorded the lien encumbers all tangible and intangible property — real or personal, legal or equitable — belonging to the obligor, and it captures future unpaid support as it accrues.
The lien attaches to bank accounts, vehicles, and real estate, and it reaches property the obligor acquires after the lien arises. Under S.C. Code § 63-17-2730, the lien does not terminate until satisfied or released as the statute provides. DSS can levy on and seize property to satisfy the child support debt under S.C. Code § 63-17-2740, and the obligor receives written notice and a right to administrative and judicial review under sections 63-17-2720 and 63-17-2760. South Carolina also extends full faith and credit to liens from other states under S.C. Code § 63-17-2770, so an arrearage lien follows the obligor across state lines. For anyone who owes child support arrears, this means home equity, vehicles, and bank balances are all exposed until the past-due balance is cleared.
Contempt of Court for Unpaid Child Support
A South Carolina family court can hold a non-paying parent in contempt and impose up to one year in jail, a $1,500 fine, and up to 300 hours of public works under S.C. Code § 63-3-620. Contempt proceedings begin with a Rule to Show Cause, which orders the obligor to appear and explain why they should not be held in contempt for failing to pay court-ordered support.
There are two routes to a Rule to Show Cause. When support is paid through the clerk of court, the clerk can issue a "bookkeeping" rule once the account falls past due under Family Court Rule 24. When support is paid directly between parents, the recipient parent files the rule. Critically, filing a support-related Rule to Show Cause carries no $25 motion fee — child and spousal support rules are exempt under S.C. Code § 8-21-320, making enforcement essentially free to initiate. Most child support contempt is civil contempt, meaning the obligor "holds the keys to their own cell": the court can order jail until the obligor makes a purge payment of the overdue amount, releasing them once they comply if they have the ability to pay. A separate criminal nonsupport misdemeanor exists under S.C. Code § 63-5-20, but prosecutions under it are rare.
Can Back Child Support Be Reduced or Forgiven in South Carolina?
South Carolina courts cannot retroactively reduce or modify child support arrears that are already due and unpaid. Each missed payment becomes a vested judgment the moment it accrues, so a court has no authority to erase or lower the accumulated child support debt, even if the obligor's income later dropped or circumstances changed during the arrears period.
The only practical paths to reducing arrears are narrow. If the arrears are owed directly to the custodial parent (not to the state for reimbursement of public assistance), that parent may agree to forgive some or all of the debt, but the agreement must be presented to and approved by the family court — a private handshake does not bind the court record. Arrears assigned to DSS to repay TANF benefits generally cannot be waived by the other parent because the debt is owed to the state. The most important protective step for an obligor is forward-looking: a parent who cannot afford current support must file to modify the ongoing order promptly, because modification applies only to future payments. Any amount that comes due before the modification is granted remains fully owed. Waiting to seek modification guarantees the past due child support balance keeps growing.
How to Collect Back Child Support in South Carolina
A parent owed back child support in South Carolina can pursue collection through DSS Child Support Services for free or by filing a private Rule to Show Cause in family court. DSS enrollment opens automated tools — wage withholding, tax intercepts, license suspension, liens, and credit reporting — while a privately filed rule lets the parent seek contempt sanctions directly, with no filing fee for support matters.
To use DSS, the recipient applies for child support enforcement services through the Child Support Services Division, which then locates the obligor, establishes any needed orders, and enforces the arrearage administratively. Under S.C. Code § 63-17-3270, the support enforcement agency has defined duties to pursue and collect support. For parents who prefer the court route or want faster contempt action, filing a Rule to Show Cause asks the family court to compel payment and impose sanctions under S.C. Code § 63-3-620. One critical rule: in South Carolina, direct payments made outside the court or DSS system may not count unless properly documented, so recipients should insist on payment through the clerk or DSS and obligors should never pay informally without records. Combining DSS enforcement with a court rule often produces the fastest collection of past due child support.
What to Do If You Owe Back Child Support in South Carolina
A parent who owes back child support in South Carolina should pay through the clerk of court or DSS, document every payment, and immediately file to modify any current order that exceeds their ability to pay. Because arrears never expire, carry no interest, and cannot be retroactively reduced, ignoring a child support debt only invites license suspension, liens, intercepts, and contempt — it never makes the balance go away.
The most effective steps are practical and prompt. First, enter a written payment agreement with DSS during any 45-day license-suspension notice window to keep your driver's or professional license active. Second, always pay through the official channel; informal direct payments may not be credited and can leave you owing twice. Third, if your income has genuinely fallen, file a modification action right away — it only affects future support, so every month of delay adds to the permanent arrears. Fourth, at a contempt hearing, be prepared to show inability to pay, since civil contempt jail requires the present ability to make a purge payment. Finally, consult a South Carolina family law attorney before any Rule to Show Cause hearing; the difference between a payment plan and a jail sentence often turns on how the obligor documents income and good-faith effort to address the past due child support.
