How is child support calculated in Ohio?

Ohio uses the Income Shares Model, which considers both parents' incomes, parenting time, healthcare costs, childcare expenses, and other factors. Our free Ohio Child Support Calculator can estimate your potential support obligation.

How long does child support last in Ohio?

Child support in Ohio typically continues until the child turns 18 or graduates high school (whichever is later), but no later than age 19. Support may continue for children with disabilities or be extended by agreement.

What if my ex isn't paying child support?

If child support isn't being paid, you can file for contempt of court, work with the Child Support Enforcement Agency (CSEA), or pursue wage garnishment. An attorney can help you choose the most effective enforcement method.

Can child support be modified in Ohio?

Yes, child support can be modified when there's a substantial change in circumstances, typically when recalculation would result in a 10% or greater change. Common reasons include job loss, income changes, or changes in parenting time.

Does paying child support give me custody or parenting time in Ohio?

No. Child support and parenting time are separate issues in Ohio. A parent's obligation to pay support is not contingent on receiving parenting time, and being denied parenting time does not excuse nonpayment of support. If you have concerns about either, address them through the court — for example, by filing to enforce parenting time or to modify support — rather than withholding payments or visitation.

Every child deserves financial support from both parents.

We serve families in all 88 Ohio counties.

How child support is calculated in Ohio

Ohio uses the Income Shares Model, which considers both parents' incomes, parenting time, health-insurance costs, childcare expenses, and other factors to determine a fair support amount. The goal is for the child to receive the level of support they would have if the parents shared a household.

Our free Ohio Child Support Calculator can estimate your likely obligation so you go into the process with realistic numbers.

Establishing a support order

Support can be established as part of a divorce, dissolution, or paternity case, or as a standalone matter. For unmarried parents, paternity may need to be established before support is ordered.

We help you put an accurate, enforceable order in place so your child's needs are met.

Enforcing child support

When support isn't paid, you have options: filing for contempt of court, working with the Child Support Enforcement Agency (CSEA), or pursuing wage garnishment. The right tool depends on your situation.

We help you choose the most effective enforcement method and pursue the arrears your child is owed.

Modifying child support

Child support can be modified when there's a substantial change in circumstances — commonly a change that would alter the amount by 10% or more, or a significant change in income, parenting time, or the child's needs.

If your income drops, file to modify promptly; support generally can't be reduced retroactively before you file.

How long support lasts

Child support in Ohio typically continues until the child turns 18 or graduates high school, whichever is later, but generally no later than age 19. Support may continue for a child with disabilities or be extended by agreement.

We help you understand exactly how these rules apply to your family.

What child support is meant to cover

Child support is intended to help cover a child's everyday needs — housing, food, clothing, school costs, and the ordinary expenses of raising a child — so that the child benefits from both parents' financial resources. Ohio's Income Shares Model is built around the idea that a child should receive roughly the same level of support they would have if the parents shared one household.

The guideline calculation already factors in significant costs like health-insurance premiums and work-related childcare. Some expenses, such as extraordinary medical needs or agreed extracurricular costs, may be addressed separately depending on your circumstances. Understanding what's baked into the number — and what isn't — helps both parents plan and reduces later disputes.

If you believe your current order doesn't reflect your child's real needs or both parents' actual incomes, you may be able to seek a review. Our free Ohio Child Support Calculator gives you an early estimate, and our attorneys can help you establish, enforce, or modify support so the order genuinely serves your child.

Getting child support right protects your children and gives both parents predictability. Whether you're setting up an order for the first time after a separation, asking the court to enforce an order the other parent is ignoring, or seeking a modification because incomes or needs have changed, the process rewards accurate financial information and careful preparation. We help you gather the right documentation, run the numbers correctly under Ohio's guidelines, and present your case clearly. The goal is an order that reflects reality and holds up over time, so your children consistently receive the support they're entitled to from both parents.

Can I do this without an attorney?

sometimes, yes. Ohio lets you represent yourself, and for a genuinely agreed dissolution or a simple motion, some people do. Every Ohio county's forms and local rules are linked from our county pages, and our free tools will draft a parenting plan or estimate child support before you spend anything.

Here's what the online-divorce platforms leave out: most Ohio counties require their own forms and language on top of the statewide ones, and a rejected filing is the most common reason people call us after trying it alone. A $25, 30-minute call tells you whether you can do this yourself — and if you can, we'll say so.
