When Does Child Support End?

In most states, child support ends when the child is 18 years of age, goes to college, dies, or gets married. But some states allow child support orders to continue beyond the 18th birthday in certain circumstances. For example, if the child is still living at home and attending high school full-time or if the child has special needs.

There are steps to take if you want to terminate your court-ordered child support obligation. This is also true for the custodial parent who wants to continue receiving support. If you fail to act, you could end up making payments beyond the actual end date. Or you can risk getting cut off from support when you need it most.

All parents—whether they’re paying or receiving child support—should know when their child support payments will end. Keep reading to learn the common triggers that end child support obligations and other important information about terminating child support.

Child support guidelines vary by state and county. Find an attorney near you.

The Child Reaches the “Age of Majority”

Child support laws in all states allow support to end when the child reaches the age of majority. The “age of majority” refers to the legal age established under state law when an individual is no longer a minor and can make certain legal decisions on their own behalf.

In most states, child support ends when a child turns 18 or when the child graduates from high school, whichever occurs first. In other states, the age is 21. Because the age of majority varies so widely from state to state, it is important to check your state law to see which age applies and whether there are any other circumstances that would extend support.

The Minor Child Becomes Emancipated

The term “emancipation” refers to a court process through which a minor becomes self-supporting and no longer requires the financial support of their parents. A minor may become emancipated before the age of majority, when they get married, join the military, leave home, or become economically independent. Under such circumstances, a parent no longer has the obligation to provide child support.

Child Support Beyond the Age of Majority

There are a few circumstances where child support continues after a child turns 18. They include providing care for children with disabilities and, in some states, paying for college costs.

Support for College Expenses

Some states allow child support to continue even after the age of majority when the support is used to pay for a child’s education, such as for college expenses.

For example, in New York, a family court judge can order child support and tuition and educational expenses for college until the child reaches the age of 21. But for child custody and visitation orders, the child is considered an adult once they turn 18.

If your child lives in a state that does not award college support, you may include provisions for it in a child support agreement. The family court can then adopt the child support agreement as a court order.

Support for Special Needs

State laws make exceptions for additional child support for parents who are caring for adult children who are disabled or who have special needs.

Since courts often look at disability in terms of economic hardship, a parent is usually allowed to receive support—even beyond the age of majority—to adequately care for a disabled or special needs child. The court recognizes that these parents have more expenses, including out-of-pocket medical expenses that health insurance does not cover.

Each state law may vary. In Ohio, for example, a parent needs to show the child support agency or the court prior to the child’s 18th birthday that the child:

• Had the disability before they turned 18; and
• The disability is the reason that the child cannot live alone and be self-supporting.

Child Support Modifications

Sometimes life events such as job loss, injury, or change in marital status or household income may call for a change in the current child support arrangement. When this happens, parents may ask the family court judge for a child support modification.

A child support modification is a judicial order that can significantly reduce or increase the amount of support a parent gives or receives. The judge can order a decrease in child support payments or require more child support.

For example, the noncustodial parent has a new job with less pay and then requires a decrease in support from the court. They will not pay a lower amount of child support immediately. If a parent’s income changes, they have to wait until the court orders a new amount after a hearing.

How To Request To End Child Support

Child support payments do not end automatically. You must terminate child support to stop the obligation. The person who is obligated to make child support payments must request that their child support obligation end once the child reaches the age of majority or a minor child becomes emancipated.

In some states, the child support services agency will be tracking the child’s 18th birthday or high school graduation date (as applicable). They may send both parties a notification that the termination date is approaching.

To find out whether your obligation to pay child support is ending, you can contact the child support services agency in your state for help in determining your child support end date. This may prepare you for whether you need to file a motion to terminate child support yourself or not. You can also speak with an attorney to discuss your specific rights and responsibilities.

What About Arrears After the Child Turns 18?

Child support may end when your child reaches the age of majority. But arrears, or past-due child support that is owed, don’t disappear. If you still owe past‑due child support when your child turns 18 (or 19 for full‑time high school students in many states), you must continue paying until the entire balance is paid in full.

Courts often “roll over” your existing monthly child support amount into an arrears‑only payment. These orders typically remain in place until the debt is paid off. Even though current support has ended, arrears are treated as a legal debt owed to the custodial parent. States can continue using enforcement tools (like tax refund intercepts, driver’s license suspensions, and even jail time) to collect what’s owed.

If the child support enforcement agency has placed a wage withholding order, it will continue for the arrears payment.
