Child Support in Ohio
Ohio calculates child support using the income shares model, set out in Ohio Revised Code chapter 3119. The guideline combines both parents' gross incomes and applies a statewide schedule to that total, to find the basic obligation. It then divides that obligation between the parents, based on each one's share of the combined income. Health insurance and work-related child care costs get built into the worksheet. A support order can be set as part of a domestic relations or juvenile court case. A parent can also apply through the local county Child Support Enforcement Agency, known as a CSEA. CSEAs are the county-level arm of Ohio's IV-D child support program. Which court hears a case depends on the parents' marital status. Domestic relations courts handle support tied to divorce. Juvenile courts generally handle paternity and support cases between parents who were never married.

The Ohio income shares guideline
ORC chapter 3119 tells Ohio courts to combine both parents' gross incomes. The court applies the state's basic child support schedule to that combined total, to find the obligation. Then it splits that obligation between the parents, in proportion to each one's income share.
The worksheet built into the statute adds in health insurance costs and work-related child care expenses. Ohio also has separate worksheet provisions for shared parenting arrangements. These can adjust the resulting amount, based on how parenting time is actually divided.
Applying through a county CSEA
Every Ohio county has a Child Support Enforcement Agency, or CSEA. Each one operates under the Ohio Department of Job and Family Services' Office of Child Support, the state's IV-D program. A parent can apply through the local county CSEA for paternity establishment, a support order, or enforcement.
A parent with an open domestic relations or juvenile court case can also have support decided directly as part of that case.
Which court hears the case
Support connected to a divorce or legal separation is decided in the domestic relations division of the court of common pleas. Support and paternity matters between never-married parents are generally handled in juvenile court.
A CSEA can also set up support administratively in many cases. Either process can result in an order enforceable the same way.
Modifying an Ohio order
Under ORC 3119.79, a support order can be modified in one clear situation: if recalculating the guideline with current incomes produces a result that differs from the existing order by 10 percent or more. That alone counts as a change of circumstances sufficient to justify modification.
A parent can also seek modification for other substantial changes not tied to that threshold. To request review, a parent contacts the CSEA handling the case, or files a motion in the court that issued the order.
Enforcement
CSEAs enforce Ohio orders using standard IV-D tools. These include income withholding, intercepting state and federal tax refunds, credit bureau reporting, and license suspension for significant arrears.
A parent owed support who is not getting consistent payment can contact the local CSEA to open or reactivate enforcement action.
