In Mississippi, child support lasts until the child turns 21, not 18. Under Mississippi Code § 93-11-65(8), the duty of support ends at emancipation, and emancipation occurs at age 21 or earlier if the child marries, joins the military and serves full time, or is convicted of a felony and sentenced to two or more years. A court may also find a child emancipated after 18 in limited situations. Support amounts follow the percentage guidelines in § 43-19-101, and unpaid support survives emancipation.
- Age 21 is the default end point, unless the child support judgment itself provides otherwise
- Automatic emancipation: age 21, marriage, full-time military service, or a felony sentence of two or more years
- Court-determined emancipation: leaving full-time school after 18, independent living before 21, or cohabitation without the paying parent's approval
- Guideline support runs from 14% of adjusted gross income for one child to 26% for five or more
- Arrears do not disappear at 21; missed payments become judgments by operation of law under Mississippi Code § 93-11-71
Child Support Lasts Until Age 21 in Mississippi
In Mississippi, child support lasts until the child turns 21. That direct answer surprises many parents, because most states end support at 18. Mississippi Code § 93-11-65(8) says the duty of support terminates when the child is emancipated, and emancipation occurs when the child reaches 21 unless the underlying child support judgment provides otherwise. The rule is the same whether support was ordered in a divorce, in a paternity case, or in a standalone support action.
For over 45 years, Lowrey, Fortner, & Miri P.A. has helped Pine Belt parents on both sides of these orders: parents who need support to continue, and parents who need an obligation ended or recalculated. This page covers when support ends, how to end it the right way, and how the guideline percentages work. For how support is set, modified, and enforced generally, start with our Mississippi child support guide.
What Ends Child Support Early in Mississippi?
Age 21 is the default finish line, but Mississippi Code § 93-11-65(8) lists events that emancipate a child sooner. Some end the duty of support automatically. Others end it only if the chancery court determines that emancipation has occurred.
If the child marries before turning 21, emancipation occurs under Mississippi Code § 93-11-65(8)(a). The statute says emancipation shall occur upon marriage, so this is one of the automatic events, unless the support judgment provides otherwise.
A child who joins the military and serves on a full-time basis is emancipated under § 93-11-65(8)(a). The statute requires full-time service, so weekend drill alone does not fit the language.
A child who is convicted of a felony and sentenced to incarceration of two or more years is emancipated under § 93-11-65(8)(a). For shorter incarcerations, § 93-11-65(8)(c) suspends the duty of support during the incarceration instead of ending it.
Under § 93-11-65(8)(b), the court may find a child emancipated if the child has turned 18 and discontinues full-time enrollment in school, unless the child is disabled. This one is not automatic. A judge has to make the call.
The court may also find emancipation when a child voluntarily moves out of the custodial parent's home, establishes independent living arrangements, obtains full-time employment, and stops pursuing an education before turning 21. The statute lists all of those elements together in § 93-11-65(8)(b).
A court may find a child emancipated if the child cohabits with another person without the approval of the parent obligated to pay support. Like the other § 93-11-65(8)(b) events, this takes a court determination, not just the fact itself.
One more detail from the statute is worth underlining. Every one of these rules applies "unless otherwise provided for in the underlying child support judgment." Your own order can set different terms, including terms that run longer. Read the order before you assume anything ends.
How to Terminate Child Support in Mississippi
Here is the practical problem. The statute says emancipation occurs at 21, but nothing about your paycheck knows that. If your employer withholds support from your wages, the withholding keeps running until the order behind it changes. If your order covers more than one child, the amount does not recalculate itself when the oldest turns 21. And if you are relying on one of the court-determined events, such as a child moving out or leaving school, the statute says the court may determine that emancipation has occurred. You need a ruling, not a guess.
The order controls until a chancery court modifies or terminates it. So the safe path is to file a petition in the chancery court that entered your order and ask the court to terminate the obligation, or to recalculate support for any younger children still covered. Until that happens, do not just stop paying. Under Mississippi Code § 93-11-71, any payment that stays unpaid for at least 30 days becomes a judgment against you by operation of law, and a parent who guessed wrong about emancipation can end up owing arrears plus facing enforcement. If the family's circumstances have shifted in bigger ways, custody may need attention too. See our page on child custody modification.
The Mississippi Child Support Percentages
How long support lasts is half the question. The other half is how much. Mississippi Code § 43-19-101 sets guideline percentages of the paying parent's adjusted gross income, and those percentages are a rebuttable presumption in every proceeding that sets or modifies support.
| Number of Children Due Support | Percentage of Adjusted Gross Income |
|---|---|
| 1 | 14% |
| 2 | 20% |
| 3 | 22% |
| 4 | 24% |
| 5 or more | 26% |
Source: Mississippi Code § 43-19-101(1).
Adjusted gross income has a specific definition in § 43-19-101(3). The court starts with gross income from all potential sources: wages and salary, self-employment income, commissions, investment income, workers' compensation, disability, unemployment, annuity and retirement benefits, alimony, and other earned income. Income of the paying parent's current spouse is excluded. From that number, the court subtracts federal, state, and local taxes, Social Security contributions, mandatory retirement and disability contributions, and support already being paid under an existing court order for other children. If the paying parent has other children living in his or her home, the court may subtract an amount it deems appropriate for their needs.
The guidelines also have income limits with teeth. If adjusted gross income is more than $100,000 a year or less than $10,000 a year, § 43-19-101(4) says the court shall make a written finding on whether applying the guidelines is reasonable, taking into account the basic subsistence needs of a paying parent with limited ability to pay.
Courts can deviate from the percentages, but only with a written or specific on-the-record finding that the guideline amount would be unjust or inappropriate. Mississippi Code § 43-19-103 lists the deviation criteria. They include extraordinary medical, psychological, educational, or dental expenses, the independent income of the child, the age of the child, seasonal variation in a parent's income or expenses, shared parenting arrangements that shift day-to-day costs, the total assets available to the parents and the child, and child care expenses the custodial parent pays in order to work.
Unpaid Child Support Does Not Go Away at 21
Parents sometimes assume the slate wipes clean when the child turns 21. It does not. Mississippi Code § 93-11-65(9) says a determination of emancipation does not terminate any arrearage that existed as of the date of emancipation. The full amount that came due before emancipation, plus any periodic payments the court ordered toward the arrearage, stays owed until it is paid in full.
The collection tools are serious. Under Mississippi Code § 93-11-71, support that remains unpaid for at least 30 days becomes a judgment by operation of law, fully enforceable like any other judgment in this state, and an enforcement action may be begun at any time. Once enrolled on the judgment roll, that judgment operates as a lien on the paying parent's real and personal property. The statute also allows interception or seizure of certain assets, including funds in financial institutions, settlements from civil lawsuits, certain lottery and gaming winnings, and lump-sum payments. If you are owed back support, or you are on the receiving end of an enforcement action, our contempt and enforcement page explains how these cases work in chancery court.
Child Support in Hattiesburg and the Pine Belt
Child support in Mississippi runs through chancery court. In Forrest County, that means the Paul B. Johnson Chancery Court Building in downtown Hattiesburg, a few minutes from our office at 525 Corinne Street. We handle support cases across the Pine Belt, including Forrest, Lamar, Jones, Marion, Covington, Perry, and Pearl River counties.
Local experience matters in these cases. Each chancery district has its own chancellors, its own scheduling rhythms, and its own expectations for financial disclosures. Since 1980, our firm has appeared in these courts for parents establishing support, parents asking to end an obligation the law says is over, and parents collecting support that never got paid.
How Lowrey, Fortner, & Miri Helps
We petition the chancery court to terminate support when a child turns 21, marries, enters full-time military service, or otherwise emancipates, and we follow through so wage withholding actually stops.
When the oldest child emancipates and the order covers younger children, we ask the court to reset the amount under the § 43-19-101 percentages for the children still due support.
We pursue arrears through the judgment, lien, and asset-interception tools in § 93-11-71 and through contempt proceedings. Emancipation does not erase back support, and enforcement can begin at any time.
If you are accused of stopping payments too soon, we present the emancipation facts to the court, address any arrearage claim, and work toward a resolution that matches what the statute actually requires.

Frequently Asked Questions About How Long Child Support Lasts in Mississippi
Does child support automatically stop at 21 in Mississippi?
Under Mississippi Code § 93-11-65(8)(a), emancipation occurs when the child turns 21 unless the child support judgment provides otherwise, and the duty of support ends at emancipation. In practice, wage withholding and orders covering more than one child do not adjust themselves. The safe move is to petition the chancery court to terminate or modify the order. Any unpaid balance is still owed after 21.
How do I stop paying child support in Mississippi when my child turns 21?
Start by reading your support order, because the statute lets the judgment set different terms. Then file a petition in the chancery court that entered the order, asking it to terminate the obligation or recalculate support for any younger children still covered. Do not just stop paying. Missed payments become judgments by operation of law after 30 days under Mississippi Code § 93-11-71.
What percentage of income is child support in Mississippi?
Mississippi Code § 43-19-101 sets guideline percentages of the paying parent's adjusted gross income: 14% for one child, 20% for two, 22% for three, 24% for four, and 26% for five or more. The percentages are a rebuttable presumption. A court can order a different amount only with a written or specific on-the-record finding that applying the guidelines would be unjust or inappropriate.
Can child support end before 21 in Mississippi?
Yes. Under Mississippi Code § 93-11-65(8), emancipation occurs before 21 if the child marries, joins the military and serves on a full-time basis, or is convicted of a felony and sentenced to two or more years of incarceration. A court may also find a child emancipated if, after turning 18, the child stops attending school full time, moves out and becomes self-supporting, or cohabits with another person without the approval of the paying parent.
What happens to unpaid child support after the child turns 21?
It is still owed. Mississippi Code § 93-11-65(9) says a determination of emancipation does not terminate any arrearage that existed on the date of emancipation. Under Mississippi Code § 93-11-71, payments unpaid for at least 30 days become judgments by operation of law, and an action to enforce those judgments may be begun at any time.
Does child support end at 18 in Mississippi?
No. The default rule in Mississippi Code § 93-11-65(8) is age 21, which surprises many parents. Turning 18 matters only in limited situations, such as when an 18-year-old stops attending school full time and is not disabled. Even then, support does not end on its own. The statute says the court may determine that emancipation has occurred.
Can child support last past 21 in Mississippi?
The emancipation rules in Mississippi Code § 93-11-65(8) apply unless the underlying child support judgment provides otherwise. That means the judgment itself can set different terms, and parents sometimes agree to obligations that run longer, such as help with college costs. If your judgment contains language like that, it controls, so review it with a lawyer before assuming everything ends at 21.
What counts as adjusted gross income for Mississippi child support?
Under Mississippi Code § 43-19-101(3), the court starts with gross income from all potential sources, including wages, self-employment income, commissions, investment income, workers' compensation, disability, unemployment, retirement benefits, and alimony. It then subtracts taxes, Social Security contributions, mandatory retirement contributions, and court-ordered support already being paid for other children. Income of the paying parent's current spouse is excluded.
Who handles child support termination cases in Hattiesburg?
Chancery court. Child support in Forrest, Lamar, and the surrounding Pine Belt counties is set, modified, terminated, and enforced through the chancery court system. Our office at 525 Corinne Street in Hattiesburg has handled family law matters in these courts since 1980. Call (601) 582-5015 to talk through your situation.
Does child support stop if my child goes to jail?
It depends on the sentence. Under Mississippi Code § 93-11-65(8), a child who is convicted of a felony and sentenced to two or more years of incarceration is emancipated, which ends the duty of support. For a child who is incarcerated but not emancipated, the statute suspends the duty of support for the period of the incarceration rather than ending it.
