In the state of Ohio what age does child support stop?

Ohio Law requires that Child Support continues until your child is both 18 years of age and finishes high school. If your child is over 18 years of age, the child support will continue if your child is enrolled on a full-time basis in an accredited high school; however, when your child turns 19 years of age, the child support will end. It is your obligation to inform CSEA of the emancipation.
