Child support, calculated right.
Missouri support runs through a worksheet called Form 14 — and the numbers that go into it decide the number that comes out. We make sure those inputs are accurate and fair.
Few topics generate more heat — and more myths — than child support. One parent is sure they're paying too much; the other is sure it's not enough. Here's the calming truth: in Missouri, child support isn't a judge's gut feeling or a negotiating contest. It's a calculation, and you can understand it.
Form 14: the worksheet that runs the show
Missouri courts calculate the presumed child support amount using Form 14, a standardized worksheet used in every case. In broad strokes, it works like this:
- Both parents' gross monthly incomes are combined.
- That combined income maps to a basic support amount from Missouri's schedule — an estimate of what an intact household at that income would spend on the children.
- Add-ons are included: the children's health insurance premiums and reasonable work-related childcare costs.
- The total is split between the parents in proportion to their incomes.
- The paying parent may receive an overnight visitation credit based on how many nights per year the children spend with them.
The result is the presumed correct support amount. A court can deviate from it — but only by finding the number would be unjust or inappropriate in your specific case.

Support generally continues until the child turns 18 — with two big extensions many parents don't expect:
- Still in high school? Support continues until graduation or age 21, whichever comes first.
- Going on to college or vocational school? If the child enrolls by the October after finishing high school and keeps meeting the statute's credit-hour and reporting requirements, support can continue up to age 21.
Support can end earlier if a child becomes emancipated — for example, by marrying or becoming self-supporting — and can continue longer for a child who is physically or mentally incapacitated from supporting themselves. If that's your family's situation, ask us about special needs planning too; support and long-term planning should work together.
Changing or enforcing an order
Modification
Lost a job? Income changed substantially? Parenting time shifted? Missouri allows modification when circumstances have changed in a substantial and continuing way — but the old order stays fully enforceable until a court actually changes it. File early, not after the arrears pile up.
Enforcement
If support isn't being paid, you have real tools: income withholding, interception of tax refunds, license suspension, and contempt. Unpaid support accrues as a judgment — it doesn't expire because someone waited you out.
Both sides, honestly
We represent parents who receive support and parents who pay it. The goal is the same either way: an accurate number, a clear order, and fewer reasons to end up back in court.
Support is one piece of the picture
Child support works alongside your custody arrangement and parenting plan — overnights literally change the math — and it should line up with the rest of your family's financial safety net: life insurance beneficiaries, guardianship nominations, and an up-to-date estate plan. We handle all of it under one roof in Kirksville.

Book a ConsultationFrequently Asked Questions
How is child support calculated in Missouri?
Through Form 14, a standardized worksheet. It starts with both parents' gross incomes, adds costs like health insurance premiums for the child and work-related childcare, credits the paying parent for overnights with the child, and produces a presumed monthly amount. The court presumes that number is correct unless someone shows it would be unjust or inappropriate.
Can the judge order a different amount than Form 14 says?
Yes. The Form 14 result is a rebuttable presumption. If applying it would be unjust or inappropriate in your case, the court can deviate — but it has to make that finding. In practice, most orders track Form 14, which is why getting the inputs right is the main event.
What counts as income for Form 14?
Gross income from nearly any source — wages, salary, self-employment earnings, commissions, bonuses, and more. If a parent is voluntarily unemployed or underemployed, the court can impute income based on what they could reasonably earn. Self-employment and farm income raise the most disputes, and they're where careful lawyering pays off.
When does child support end in Missouri?
Generally at 18 — but not always. If the child is still in high school, support continues until graduation or 21, whichever comes first. And if the child enrolls in college or vocational school by the October after high school and stays on track under the statute's requirements, support can continue until as late as 21. Missouri goes further than many states here, and parents are often surprised.
Can child support be changed after the order?
Yes. Either parent can seek modification when there's a substantial and continuing change in circumstances — a job loss, a big income change, a change in the parenting schedule, or new expenses for the child. Until a court actually modifies the order, though, the existing amount keeps accruing. Never just stop paying and hope.
What if the other parent isn't paying?
Missouri support orders are enforceable through income withholding, tax refund interception, license suspension, contempt proceedings, and more, through the courts and the Family Support Division. Unpaid support doesn't vanish — it accrues as a judgment. We can help you get enforcement moving.
