When Does Child Support End? Age Limits by State (2026)
In most states, child support ends when the child turns 18. However, many states extend support to age 19 or 21 under certain circumstances, such as if the child is still in high school or attending college. About 15 states have provisions requiring parents to contribute to college expenses. Child support may also continue indefinitely for children with disabilities who cannot support themselves.

When Does Child Support End?
The general rule across the United States is that child support obligations end when the child reaches the age of majority, which is 18 in most states. At that point, the child is considered a legal adult, and the non-custodial parent's duty to provide financial support through the court order typically terminates.
However, this is far from a universal rule. Several important exceptions apply:
- High school completion: Many states extend support to age 19 or until the child graduates from high school, whichever comes first. This prevents a child from losing support during their senior year.
- College attendance: Approximately 15 states allow courts to order continued support while the child attends college, often until age 21 or 23.
- Disability: Nearly all states provide for extended or indefinite support if the child has a physical or mental disability that prevents self-sufficiency.
- Court agreement: Parents can voluntarily agree to extend support beyond the statutory age in a divorce settlement or separation agreement.
- Emancipation: Conversely, support can end before 18 if the child becomes emancipated through marriage, military service, or a court order.

When Child Support Continues Past 18
While 18 is the most common termination age, there are several well-established circumstances where child support obligations continue beyond a child's 18th birthday.
College and Post-Secondary Education
Approximately 15 states have statutes allowing courts to order parents to contribute to their child's college or post-secondary education expenses. This can include tuition, room and board, books, and fees. In most of these states, the obligation continues until age 21 or 23, and the child must be enrolled full-time. The rationale is that in an intact family, parents would typically support a child through college, and divorce should not eliminate that expectation.
Disability and Special Needs
Nearly every state provides that child support may continue indefinitely if the child has a physical or mental disability that prevents them from becoming self-supporting. In some cases, support is ordered for the child's lifetime. This applies to conditions that existed before the child reached the age of majority and that make the child incapable of earning a living.
High School Completion
The majority of states extend child support until the child completes high school, even if they turn 18 before graduation. This ensures that a child who turns 18 during their senior year does not lose financial support before earning a diploma. The extension typically lasts until age 19 or 20, depending on the state.
Court Orders and Agreements
Parents can voluntarily agree to extend child support beyond the statutory termination age. If this agreement is incorporated into a divorce decree or separation agreement, it becomes enforceable by the court. Common agreements include supporting a child through college or until they achieve financial independence.
States That Require College Support
The following states have statutory provisions that allow or require courts to order child support for college-related expenses. Each state has its own rules regarding duration, conditions, and limits. To learn more about how much child support you may owe, including college contributions, use our free calculator.
Connecticut
Support may continue to age 23 for full-time students. Courts consider the child's academic performance, parents' financial resources, and available financial aid.
Illinois
Courts may order "non-minor support" for educational expenses. Contribution is divided between parents based on their ability to pay, with consideration of the child's resources.
Indiana
Support may extend to age 21 for educational needs. Courts may order contributions toward college expenses based on the parents' financial ability.
Iowa
Post-secondary education subsidy available to age 22. Covers tuition, books, and living expenses based on a state university cost standard.
Massachusetts
Support can continue to age 23 for children enrolled in an undergraduate program. The court considers the child's aptitude, ability, and the parents' financial resources.
Missouri
Support may continue to 21 if the child is attending college or vocational school. The child must be enrolled and making progress toward a degree.
New Jersey
No set termination age. Support continues until the child is emancipated, which courts may find does not occur until after college, typically around age 23.
New York
Support continues to age 21. Courts can order educational expenses as part of the support obligation, especially when previously agreed upon by parents.
Oregon
Child attending school may receive support until age 21. The child must be enrolled in school and making satisfactory academic progress.
Washington
Post-secondary support available until age 23. Dependent child must be enrolled in an accredited educational institution and the court evaluates the necessity.
How Child Support Ends
The mechanism for ending child support varies by state. Understanding how your state handles termination is critical to avoiding legal complications.
Automatic Termination
In some states, child support orders automatically terminate when the child reaches the specified age. The order itself contains a termination date, and payments simply stop. However, even in automatic-termination states, any unpaid arrears (back payments) remain enforceable and must be paid in full.
Petition Required
In many states, the paying parent must file a motion or petition with the court to officially terminate the child support order. Until the court issues a termination order, the obligation continues, even if the child has reached the age of majority. Failing to file can result in continued wage garnishment and accumulating debt.
Emancipation Events
Regardless of age, child support typically ends when the child becomes emancipated. Common emancipation events include: the child gets married, the child enlists in the military on active duty, the child is declared emancipated by a court, or the child dies. In most states, the paying parent must still petition the court to formally end the order, even after an emancipation event.
Can Child Support Be Extended?
Yes, child support can be extended beyond the standard termination age in many situations. Courts have discretion to extend support based on the circumstances of each case.
- Special needs children: If a child has a developmental disability, serious mental health condition, or physical disability that prevents self-sufficiency, courts in virtually every state can extend support indefinitely. The parent seeking the extension typically must provide medical evidence of the child's condition.
- Court discretion: Judges may extend support if doing so is in the best interest of the child. This is more common in states that give courts broad discretion over family law matters.
- Parental agreement: If both parents agree to extend support, whether as part of a divorce settlement or a modification, the court will typically approve the agreement and make it part of the order.
- Arrears enforcement: Even after the active obligation ends, the court retains jurisdiction to enforce any unpaid child support arrears. Back-owed child support does not expire with the child's age and can be collected through wage garnishment, tax refund intercepts, and other enforcement mechanisms.
How to Stop Child Support Payments
Stopping child support payments requires following proper legal procedures. Never simply stop paying child support without a court order, even if your child has reached the age of majority, has moved out, or is financially independent.
- Verify your state's termination rules. Check whether your state automatically terminates support at a certain age or whether you must file a motion. Your state's child support enforcement agency can provide this information.
- File a motion to terminate. If required in your state, file a motion with the family court that issued your child support order. Include documentation showing the child has reached the termination age or qualifying event (graduation, emancipation, etc.).
- Continue paying until the court issues an order. Until you receive a formal court order terminating your obligation, you are legally required to continue making payments. Unpaid amounts accumulate as arrears with interest.
- Resolve any arrears. If you owe back child support, the termination of your ongoing obligation does not erase the debt. You must pay all arrears in full or negotiate a payment plan with the court.
- Update your employer. Once you have a court order terminating support, provide a copy to your employer's payroll department so they can stop the income withholding.
Warning: Stopping child support payments without a court order can result in contempt of court charges, wage garnishment, driver's license suspension, passport denial, and even jail time. Always follow the legal process.
Frequently Asked Questions
At what age does child support end?
In most states, child support ends when the child turns 18. However, many states extend support to age 19 if the child is still in high school, and some states like New York and Mississippi extend support to age 21. About 15 states allow courts to order support through college, potentially extending the obligation to age 23.
Does child support end automatically at 18?
Not always. In some states, child support terminates automatically when the child reaches the age of majority. In other states, the paying parent must file a motion with the court to formally end the support order. Continuing to pay without filing a motion does not create a credit, and stopping without a court order can result in contempt charges.
Can child support continue after 18 if my child goes to college?
Yes, in approximately 15 states. States like Connecticut, Indiana, Iowa, Massachusetts, Missouri, New Jersey, New York, Oregon, Utah, and Washington have provisions allowing courts to order child support to continue while the child attends college, typically until age 21 or 23 depending on the state. The child generally must be enrolled full-time and making satisfactory academic progress.
Does child support end if the child gets a job?
Not automatically. A child earning income does not end child support. However, if the child becomes legally emancipated -- through marriage, joining the military, or a court order of emancipation -- child support obligations typically end regardless of age. Simply having a part-time or full-time job while under the age of majority does not constitute emancipation.
What happens to child support if my child has a disability?
Most states allow child support to continue indefinitely for adult children with physical or mental disabilities who cannot support themselves. The paying parent may need to continue support as long as the disability prevents the child from becoming self-sufficient. In some cases, support lasts for the child's entire life. The parent seeking extended support typically must provide medical documentation of the child's condition.
Can I just stop paying child support when my child turns 18?
No. Even if your child has reached the age of majority, you should not stop paying child support without a court order terminating your obligation. Unilaterally stopping payments can result in contempt of court, wage garnishment, license suspension, and other enforcement actions. File a motion to terminate support through the proper legal channels, and continue paying until the court issues an order.
