Married or divorcing parents resolve support inside the divorce/dissolution at the Court of Common Pleas; never-married parents do it in the Juvenile Court after parentage is established.

How to File Child Support in Clinton County

Run the Ohio Child Support Worksheet. Use the official Ohio Child Support Calculator (2024 Income Shares Model), then print and sign the worksheet to file with your case.
Pick the right path — Common Pleas, Juvenile, or CSEA. Married or divorcing parents resolve support in the Court of Common Pleas. Never-married parents use the Juvenile Court or ask CSEA at (937) 382-5726 to establish it administratively.
Establish parentage first if you were never married. Support cannot be ordered until parentage is established by Acknowledgment of Paternity, a CSEA administrative order, or a court judgment.
File the motion or open a CSEA case. To change an existing order, file a Motion for Change of Child Support (Form 28 / Juvenile Form 7) with an updated worksheet in the issuing court, or request a free CSEA review.
Set up payment through CSPC. Once an order is entered, payments and wage withholding route through Ohio Child Support Payment Central so there is a clear record of what was paid.

Clinton County Practice Notes

Ohio 2024 Income Shares Model. Ohio sets support using both parents' combined gross income, the number of children, and credits for health-insurance and childcare costs. Run the official Ohio Child Support Computation Worksheet, print it, and sign it any time you ask the court to set or change support.
CSEA reviews and enforcement. The Clinton County CSEA — (937) 382-5726 — can establish parentage and support, run genetic testing, set wage withholding, and review orders for free (generally every 36 months, or sooner on a 10%+ change). Payments go through Ohio Child Support Payment Central (CSPC).
Modify the order, don't just stop paying. Support continues at the ordered amount until a court or CSEA changes it. If your income drops, file a Motion for Change of Child Support (Form 28 / Juvenile Form 7) or request a CSEA review right away — changes are generally effective from the date you file, not the date your circumstances changed.
