Child support in South Carolina generally ends when the child turns 18, but continues through high school graduation if the child is still enrolled — up to the end of the school year after the child turns 19. Under S.C. Code Ann. § 63-3-530(A)(17), support obligations terminate upon the earliest of three events: the child reaching 18 (or 19 if still in high school), the child marrying, or the child becoming self-supporting. Payments do not stop automatically. The paying parent must petition the Family Court or notify the SC Department of Social Services to formally end the obligation. Filing a termination petition costs $150 in South Carolina Family Court.

Standard Age of Termination for Child Support in South Carolina
Child support in South Carolina ends at age 18 under S.C. Code Ann. § 63-3-530(A)(17), making 18 the age of majority for support purposes. South Carolina courts define termination as occurring when the child reaches 18, marries, or becomes self-supporting, whichever happens first. This statute governs every child support order issued by the Family Court system.
The precise statutory language states that child support orders "run until the child turns eighteen years of age or until the child is married or becomes self-supporting, as determined by the court, whichever occurs first." South Carolina does not recognize automatic termination. Even when a child turns 18 and has graduated from high school, the paying parent carries the legal responsibility to petition the court or file paperwork with the SC Department of Social Services Child Support Division to stop wage garnishment or direct payments.
Parents who simply stop paying when a child turns 18 risk contempt of court charges. Arrearages that accumulated before the termination date remain enforceable. Under S.C. Code Ann. § 63-3-530(A)(17), no new arrearage may accrue after the termination event (18th birthday, graduation, or end of the school year at age 19), but all existing arrears must be paid in full regardless of the child reaching adulthood.
High School Enrollment Extension Beyond Age 18
Child support continues past age 18 if the child is still enrolled in and attending high school, extending through graduation or the end of the school year after the child turns 19 — whichever comes later. This extension under S.C. Code Ann. § 63-3-530(A)(17) operates automatically without requiring a new court order, meaning support simply continues if the child remains in high school at 18.
This provision addresses students who turn 18 during their senior year. A child born in September who turns 18 in September of their senior year would receive continued support through their May or June graduation. A child who was held back a grade and turns 19 during the school year would receive support through the end of that school year but not beyond. The outer limit is absolute: no child support obligation extends past the conclusion of the school year in which the child turns 19.
The paying parent does not need to request this extension. It is built into the standard child support order under South Carolina law. However, if the child drops out of high school after turning 18, the paying parent can petition the court to terminate the obligation immediately, since the child is no longer enrolled and attending.
Emancipation Events That End Child Support Early
A child becomes emancipated before age 18 through marriage, entry into the armed forces, or becoming self-supporting as determined by the court. South Carolina has no formal emancipation petition process for minors. Under S.C. Code Ann. § 63-17-720(5), a "dependent child" excludes any child who is emancipated, self-supporting, married, or serving in the armed forces.
Emancipation is never presumed in South Carolina. The parent seeking to terminate support based on emancipation bears the full burden of proof. A child living independently and earning income does not automatically qualify as emancipated. The court examines whether the child has truly left the parental home and achieved financial self-sufficiency. A part-time job while living at home does not constitute self-support.
When families have multiple children covered by a single support order, one child reaching emancipation does not automatically reduce the support amount for the remaining children. The paying parent must file a formal petition for modification under S.C. Code Ann. § 63-17-310, demonstrating a substantial change in circumstances. The court then recalculates support using the current South Carolina Child Support Guidelines — which were updated effective January 1, 2024, with obligations approximately 25% higher than the previous 2014 guidelines.
Child Support for Disabled Adult Children
South Carolina courts can order child support to continue indefinitely for children with physical or mental disabilities that prevent self-support. S.C. Code Ann. § 63-3-530(A)(17) expressly authorizes support "for as long as the physical or mental disabilities or exceptional circumstances continue," with no upper age limit. A disabled adult child may receive support for life if they cannot achieve financial independence.
The disability must have existed or been known to exist on or before the child's 18th birthday. A parent seeking continued support must demonstrate that the child's condition causes ongoing dependency and an inability to become self-supporting. The Family Court considers the kind and severity of the disability, the child's health status, the degree of financial need, the cost of therapy and medical care, and input from the SC Department of Disabilities and Special Needs.
If a disabled adult child later gains employment or achieves financial independence, the paying parent may petition for modification or termination. The court evaluates whether the changed circumstances are substantial and ongoing. Temporary employment during a period of relative health does not necessarily warrant termination if the underlying condition persists.
College Support Obligations After Age 18
South Carolina family courts have discretionary authority to order divorced or unmarried parents to contribute to a child's college expenses, even after the child turns 18. This authority was restored by the South Carolina Supreme Court in McLeod v. Starnes (2012), which overruled the 2010 Webb v. Sowell decision that had briefly eliminated court-ordered college support on equal protection grounds.
Courts apply the Risinger factors when evaluating college support requests. The court considers whether the child demonstrates characteristics indicating they would benefit from college, whether the child has the academic ability to make satisfactory grades, whether the child cannot attend college without parental financial help, and whether the parent has the financial ability to contribute. College support is not mandatory and is entirely within the Family Court's discretion.
Parents can also agree to college support provisions in their divorce settlement or consent order. Including specific terms about college contributions — such as percentage splits, GPA requirements, and maximum duration — avoids future litigation. A parent ordered to pay college support who experiences a significant financial change can petition for modification under S.C. Code Ann. § 63-17-310.
How to File for Termination of Child Support in South Carolina
Terminating child support in South Carolina requires filing a petition in the Family Court that issued the original order, paying a $150 filing fee, and serving the other parent with the petition. The process typically takes 60 to 120 days from filing to final order, depending on whether the other parent contests the termination. As of March 2026, verify the current filing fee with your local clerk of court.
The petition must include an affidavit documenting the basis for termination — the child turning 18, graduating from high school, marrying, or becoming self-supporting. Supporting documents include the child's birth certificate, high school diploma or transcript, marriage certificate, or evidence of employment and independent living. Both parents can consent to termination, which streamlines the process and may eliminate the need for a hearing.
Self-represented litigants can access free interactive forms at ModifyChildSupportSC.com, an online program maintained for South Carolina self-represented parties. For cases administered through the SC Department of Social Services, parents can contact the Child Support Division directly to request a review and adjustment. DSS forms are available at dss.sc.gov/child-support/forms/. The $150 filing fee can be waived by filing an Affidavit of Indigency (Form SCCA/400) for parents who cannot afford court costs.

2024 Child Support Guidelines Update and Its Impact
South Carolina implemented updated Child Support Guidelines effective January 1, 2024, marking the first revision in 10 years since the 2014 guidelines. Support obligations under the new guidelines are approximately 25% higher than under the previous schedule. The combined gross income threshold was extended from $30,000 per month to $40,000 per month, capturing higher-income families that previously fell outside the guidelines.
The 2024 update introduced a new Extraordinary Medical Expense provision allowing recurring medical costs — including therapy, prescriptions, and specialized treatments — to be built directly into monthly support calculations. Previously, these expenses required separate reimbursement arrangements between parents. The updated guidelines also revised the self-support reserve amount and child care expense thresholds.
Parents with existing orders based on the 2014 guidelines can petition for modification if the new guidelines would produce a significantly different result. Under South Carolina law, a difference of 20% or more between the existing order and the guidelines calculation creates a rebuttable presumption that modification is warranted. Given the approximately 25% increase in the 2024 guidelines, many existing orders may qualify for upward modification.
Pending Legislation: 2025-2026 Bills Affecting Child Support
Two bills introduced in the 2025-2026 South Carolina legislative session could affect child support obligations. Bill 3009 would authorize the SC Department of Social Services Division of Child Support Enforcement to enforce certain alimony obligations beginning January 1, 2026, expanding DSS enforcement beyond child support. Bill 3085 would create a rebuttable presumption of approximately equal parenting time when both parents are willing, able, and fit, which could affect child support calculations by changing the overnight allocation between parents.
Neither bill had been enacted as of March 2026. Parents should monitor the South Carolina Legislature website at scstatehouse.gov for updates on these proposals. Changes to parenting time presumptions would directly impact child support calculations under the South Carolina guidelines, since overnight allocations affect the shared parenting adjustment in the support formula.
Frequently Asked Questions
Does child support automatically stop at 18 in South Carolina?
No. Child support does not automatically stop at age 18 in South Carolina. The paying parent must file a petition to terminate support in Family Court (filing fee: $150) or request termination through the SC Department of Social Services. Under S.C. Code Ann. § 63-3-530(A)(17), support continues until a court order formally ends the obligation, and wage garnishment continues until terminated.
When does child support end in South Carolina if my child is still in high school?
Child support extends past age 18 if the child remains enrolled in and attending high school, continuing through graduation or the end of the school year after the child turns 19 — whichever comes later. Under S.C. Code Ann. § 63-3-530(A)(17), this extension is automatic and does not require a new court order. The absolute outer limit is the conclusion of the school year when the child turns 19.
Can South Carolina courts order parents to pay for college?
Yes. Since the 2012 McLeod v. Starnes decision, South Carolina family courts have discretionary authority to order divorced or unmarried parents to contribute to college expenses. Courts evaluate the child's academic ability, the child's need for financial assistance, and the parent's ability to pay using the Risinger factors. College support is not guaranteed and depends on the specific circumstances of each case.
How much does it cost to file for child support termination in South Carolina?
The filing fee for a child support termination or modification petition in South Carolina Family Court is $150. Additional costs include process server fees ($50 to $125) and certified copies ($2 to $5 per page). Self-represented parties with financial hardship can file an Affidavit of Indigency (Form SCCA/400) to waive the filing fee entirely. As of March 2026, verify fees with your local clerk.
Does child support continue for a disabled child past age 18 in South Carolina?
Yes. S.C. Code Ann. § 63-3-530(A)(17) authorizes child support to continue indefinitely for children with physical or mental disabilities that prevent self-support. The disability must have existed or been known before the child turned 18. Support continues "for as long as the physical or mental disabilities or exceptional circumstances continue," with no upper age limit.
What counts as emancipation for ending child support in South Carolina?
Emancipation in South Carolina occurs through marriage, entry into the armed forces, or becoming self-supporting as determined by the court. Under S.C. Code Ann. § 63-17-720(5), a dependent child excludes anyone who is emancipated, self-supporting, married, or in military service. South Carolina has no formal petition process for minors to seek emancipation. The burden of proving emancipation falls on the party asserting it.
What happens to child support arrears after my child turns 18?
All child support arrears that accumulated before the termination date remain fully enforceable regardless of the child's age. Under S.C. Code Ann. § 63-3-530(A)(17), no new arrearage may accrue after the termination event (18th birthday, graduation, or end of school year at 19). However, existing arrears can be collected through wage garnishment, tax refund intercepts, and contempt proceedings until paid in full.
How did the 2024 South Carolina child support guidelines change support amounts?
The 2024 guidelines update — the first revision since 2014 — increased child support obligations by approximately 25%. The combined gross income threshold expanded from $30,000 to $40,000 per month. A new Extraordinary Medical Expense provision allows recurring medical costs to be incorporated directly into monthly calculations. Parents with orders based on the 2014 guidelines may petition for modification if the new guidelines produce a 20% or greater difference.
Can I modify child support if my financial situation changes?
Yes. Under S.C. Code Ann. § 63-17-310, either parent can petition the Family Court for modification based on a substantial change in circumstances. Job loss, income changes, disability, and changes in the child's needs all qualify. The filing fee is $150. DSS-administered cases can also be reviewed through the Child Support Division's administrative process at no cost to the parent.
What is the residency requirement to file for divorce in South Carolina?
Under S.C. Code Ann. § 20-3-10, if both spouses reside in South Carolina, the filing spouse must have lived in the state for at least 3 months before filing. If only one spouse lives in South Carolina, that spouse must have resided in the state for at least 1 year (12 months). Active-duty military personnel stationed in South Carolina satisfy the residency requirement.
