Darke County, Ohio · Greenville

Ohio sets child support with a statewide formula — the 2024 Income Shares model — run on the official Ohio Child Support Calculator. In Darke County, support is decided inside a divorce or dissolution at the Domestic Relations Division of the Court of Common Pleas for married parents, and in the Probate/Juvenile Court for never-married parents. The Darke County CSEA, (937) 548-4132 option 4, opens cases, collects by income withholding, and pays through the state.

How is child support set in Darke County, Ohio?

Child support is calculated with Ohio's 2024 Income Shares worksheet, run on the official Ohio Child Support Calculator using both parents' incomes, health-insurance costs, and parenting time. Married or divorcing parents set support inside their divorce or dissolution at the Domestic Relations Division of the Darke County Court of Common Pleas; never-married parents set it in the Probate/Juvenile Court (paternity must be established first). Either way, you file a IV-D Application so the Darke County CSEA, (937) 548-4132 option 4, can collect support by income withholding and pay it through the state. Confirm any deposit with the Clerk at (937) 547-7335.

You can provide both parents' income and the cost of the children's health insurance.
You understand support is set by Ohio's statewide formula, not by the county.
You can open a IV-D case with the Darke County CSEA so support is withheld and paid through the state.

Darke County Practice Notes

Support is calculated, then collected through the CSEA. Ohio's 2024 Income Shares worksheet sets the number; the Darke County CSEA at 631 Wagner Ave, Greenville, (937) 548-4132 option 4 (or (800) 501-5635), then collects it by automatic income withholding and pays it through the state.
A IV-D Application travels with the case. Darke County's DR pleading list (Local Rule 2(F)) requires an Application for Child Support Services with any DR case involving children, and post-decree filings require an updated IV-D Application (Rule 7(H)).
Where you file depends on marriage, not residence. Married or divorcing parents set support in the Common Pleas DR case; never-married parents set it in the Probate/Juvenile Court after parentage is established. The amount is the same statewide formula in both courts.
