The short answer: for child support orders entered on or after July 1, 1997, the obligation ends when the child turns 19. Not 18. Not 21. Colorado is one of a handful of states where the default emancipation age is 19 — and that surprises parents on both sides of the equation.

But 19 isn’t always the finish line. Three exceptions can push the end date later, and one common situation — a child still in high school at 19 — creates enough confusion that it’s worth walking through in detail.

The Default Rule: Age 19

Under C.R.S. § 14-10-115(13)(a), a child is considered emancipated when they turn 19, and the child support obligation terminates at that point. This applies to orders entered on or after July 1, 1997. Orders entered before that date may operate under different rules — the original decree controls.

The 19-year-old cutoff is often confused with 18 (the age of legal majority for most purposes in Colorado) or 21 (the age used in some other states). Colorado family law treats them differently: a child can vote, sign contracts, and enlist in the military at 18, but child support continues for another year unless an earlier emancipation trigger — marriage, active military duty, or court-determined self-sufficiency — applies first.

The High School Exception

The most common reason child support extends past 19 is straightforward: the child is still in high school.

Under C.R.S. § 14-10-115(13)(a), if the child is enrolled in high school or an equivalent program when they turn 19, support continues until the end of the month following graduation — but never beyond age 21.

Here’s how that plays out in practice. A child turns 19 in March of their senior year. They graduate in May. Support continues through the end of June — the month following graduation — unless the parents agreed otherwise.

The statute also addresses what happens when a child leaves school and later returns. If a child drops out of high school, the support obligation may be eligible for termination at that point. If the same child reenrolls later, support resumes upon reenrollment and continues until the end of the month after graduation, capped at age 21.

There’s a gray zone here worth acknowledging. The statute says “high school or equivalent program” but doesn’t define what qualifies as “equivalent.” A traditional high school diploma program clearly counts. A GED program or alternative high school is less clear, and the answer may depend on how the court in a specific judicial district interprets “equivalent.” The JDF 1426 instructions don’t address this question.

The Disability Exception

A court may order child support to continue beyond age 19 for a child who is mentally or physically disabled. Under C.R.S. § 14-10-115(13)(a), the court or delegate child support enforcement unit can extend the obligation, including medical expenses and insurance coverage.

This exception doesn’t apply automatically. A parent seeking continued support under this provision would need to present it to the court. The statute doesn’t define the threshold for what constitutes a qualifying disability in this context.

The Written Agreement Exception

Both parents can agree in writing to extend child support past age 19. This agreement sometimes appears in the original divorce decree or separation agreement — a provision stating that support will continue through college, for example, or until age 21.

When that written agreement exists, it controls. The default age-19 termination doesn’t override an agreement between the parents. Whether a specific provision in a decree constitutes such an agreement depends on the language of the decree itself.

What to File When the Child Turns 19

The support obligation terminates by operation of law at 19, but the court order and any wage withholding remain active until someone files the paperwork. The termination filing requires JDF 1408 (Motion to Terminate Child Support) and JDF 1409 (Order to Terminate Child Support) — a two-form bundle with no financial statement and no child support worksheet. The filing fee is $105, and the court typically reviews the motion within 49 days.

After the court enters the order, one more step remains: delivering the termination order and JDF 84 (Notice to Terminate Income Assignment) to the employer’s payroll department so the wage withholding actually stops. Without that step, deductions continue even after the court says the obligation is over.

The JDF 1408 guide and the JDF 84 guide cover both steps in detail.

Colorado’s age-19 default is one of the clearer rules in family law — until the exceptions come into play. For most parents, the process is mechanical: the child turns 19, nobody’s claiming a high school exception or disability, and the filing is two forms and a $105 fee. Where it gets complicated is when the child is still in school, when there’s a written agreement in the decree, or when a disability may warrant continued support. Those situations involve fact-specific questions that the self-help forms don’t attempt to resolve on their own.
