Child support in Georgia does not automatically stop at 18 in every case. Eighteen is the default end date under state law, but a child still finishing high school, a disability that began in childhood, a written agreement between the parents, or unpaid arrears can all keep the obligation alive. And even when the obligation itself ends, paycheck withholding and enforcement tools usually keep running until someone files paperwork to shut them off.
The Default Rule at 18
Georgia ties child support to the age of majority. Under O.C.G.A. § 19-6-15(e), the duty to support a minor child ends when the child turns 18, dies, marries, or becomes emancipated, whichever comes first.1Georgia Courts. Georgia Code 19-6-15 – Child Support Statute For most families, the 18th birthday is the date that matters.
Three events can end support earlier than 18:
- The child legally marries.
- The child is legally emancipated by a court, based on independent living and financial self-sufficiency.
- The child enters military service, which generally establishes the kind of economic independence that constitutes emancipation, typically confirmed by a court finding rather than kicking in automatically.
These events end support entirely rather than reducing or pausing it. If a 17-year-old marries, the obligation stops on the wedding date, not on the child’s next birthday.1Georgia Courts. Georgia Code 19-6-15 – Child Support Statute
When Support Continues Past 18
Still in High School
The most common reason support runs past 18 is the high school exception. If a child turns 18 without having graduated from secondary school, a court can order support to continue as long as the child is enrolled and attending, is not married, and has not been emancipated.2Georgia Department of Human Services Division of Child Support Services. FAQ – Section: My child is still in school. Why has child support stopped? A child who turns 18 in January of senior year is still covered through graduation that spring.
There is a hard cap. Support under this exception cannot be required after the child turns 20, regardless of where the child stands in school.1Georgia Courts. Georgia Code 19-6-15 – Child Support Statute
A Disability That Began in Childhood
Georgia law makes a separate exception for adult children who cannot support themselves because of a physical or mental disability. Under O.C.G.A. § 19-6-15.1, a “dependent adult child” is an unmarried person who has reached majority and is incapable of self-support due to an incapacity that began before age 18. Either parent can petition the court for continued support. The court has discretion over the amount and terms and will weigh the child’s disability-related needs alongside both parents’ finances.3Justia. Georgia Code 19-6-15.2 – Determination of Support for Dependent Adult Children Unlike the high school extension, there is no age cap. Support can continue as long as the qualifying disability persists.
A Written Agreement Between the Parents
Georgia courts cannot order a parent to pay for college or other post-majority expenses on their own. That authority does not exist under state law. Parents can voluntarily agree to it, though, and often do as part of a divorce settlement or custody agreement, covering things like tuition, room and board, or health insurance for a child in school past 18.
Once both parents sign and the agreement becomes part of a court order, it is enforceable like any other provision of the settlement. The distinction matters: your ex’s written promise to split college costs is binding, but without a signed agreement, no judge can create that obligation later.
Multi-Child Orders Do Not Adjust Automatically
If your order covers more than one child, the monthly amount does not drop when the oldest turns 18. Georgia support is typically set as a single figure for all covered children, and that figure stays in place until a court modifies it.
You have to file a petition to recalculate support based on the children still covered. Until a new order is entered, the original amount is owed in full, and anything short of that creates arrears. Every month of delay between the oldest aging out and the modified order being signed is a month you owe the unmodified figure. If you and the other parent agree on the new number, a consent modification is faster and cheaper than a contested hearing.
Income Withholding Keeps Running Until You Stop It
If support comes out of your paycheck through an Income Withholding Order, the deductions do not stop when the child turns 18 or graduates. The withholding order stays in effect until a court says otherwise or the support order expires by its own terms.4Justia. Georgia Code 19-6-32 – Entering Income Withholding Order or Medical Support Notice for Award of Child Support Stopping the withholding is your job.
If the Other Parent Cooperates
The cleanest route is a Consent Order to Terminate Income Withholding. Both parents sign a motion confirming the obligation has been paid in full, attach the child’s birth certificate and proof of high school graduation, and file it with the clerk of court. A judge signs the order, and the employer receives it and stops the deductions.5Georgia Courts. Terminate Income Withholding When Children Age Out of the Order
If the Other Parent Will Not Sign
If the custodial parent refuses to sign, it gets harder. Some employers will stop current-support withholding on their own once they see documentation that the child has aged out. Many will not, because a court order protects them from liability. You will likely need an attorney to file a motion to terminate the withholding.5Georgia Courts. Terminate Income Withholding When Children Age Out of the Order Cases handled by Georgia’s Division of Child Support Services have their own termination procedures; contact the agency directly.
Move quickly. Georgia law does not provide a straightforward refund mechanism for overpaid child support, and recovering money that has already gone to the other parent typically requires a separate court proceeding.
Unpaid Arrears Do Not Go Away
When a child ages out, future payments may end, but every dollar of unpaid support that built up before that date remains a legally enforceable debt. Each missed payment becomes a judgment by operation of law on the date it was due, and those judgments are not subject to retroactive modification.6Georgia General Assembly. Georgia Code 19-6-17 – Application for Child Support Following Custody Award Georgia does not apply a statute of limitations to the collection of child support arrears.
The enforcement tools are aggressive. The Division of Child Support Services and private attorneys can garnish wages, intercept tax refunds, and place liens on property. For arrears above $2,500, the federal government can deny, revoke, or restrict your U.S. passport.7Office of the Law Revision Counsel. 42 USC 652 – Duties of Secretary Georgia can also suspend your driver’s license if your arrears equal or exceed three months of your total monthly support obligation and recent payments fall short of that threshold.8Georgia Department of Human Services Division of Child Support Services.

What to Do as the End Date Approaches
Pull out your original support order and read the termination language carefully. Some orders specify an exact end date or triggering event; others are silent and default to the statute. If your child will still be in high school past 18, check whether the order already addresses the extension or whether a modification is needed.
For multi-child orders, start the modification process before the oldest child ages out, not after. Courts do not move quickly, and delay costs you the unmodified amount every month.
Keep records. Save the child’s birth certificate, high school diploma or GED, and any communication with the other parent about the end of support. If a dispute later arises about whether you overpaid or underpaid, documentation is what separates a quick resolution from an expensive fight.
