Child Support in Ohio
State-specific overview · Family Law
Ohio uses income shares model; support ends at age 18 unless the child is still in high school.
How Ohio treats Child Support
Ohio applies the income shares formula, calculating support as a percentage of combined parental income adjusted for custody time. The state considers both parents' gross income, including wages, self-employment income, and other sources. Child support terminates when the child turns 18, except if the child is still attending high school, in which case support continues until graduation or age 19, whichever occurs first. Modifications require a 10% change in either parent's income or a substantial and continuing change in circumstances.
The general definition of Child Support
Court-ordered payments from one parent to the other for a child's living expenses.
Child support is money that a court requires one parent to pay to the other parent (or guardian) to help cover the child's expenses like food, housing, education, and healthcare. The amount is usually calculated using state guidelines that consider both parents' incomes, the number of children, and custody arrangements. Child support continues until the child reaches the age of majority, typically 18 or 21 depending on the state. It's a legal obligation separate from custody decisions.
