Duration of Child Support Obligations in Ohio

When Does Child Support End in Ohio?

Generally, support terminates when the child:

• Turns 18 (or 19 if still in high school).
• Graduates high school.
• Marries.
• Joins the military.
• Becomes legally emancipated.

Exceptions: Support may continue beyond 18 if the child has a physical/mental disability preventing self‑support. Orders can be modified or terminated upon substantial change in circumstances (income, custody, needs). Legal advice is recommended for specific cases.
