Mahoning County, Ohio · Youngstown

Ohio sets child support with the 2024 Income Shares worksheet (R.C. Chapter 3119). Where you handle support in Mahoning County depends on your situation: married or divorcing parents set support inside their Domestic Relations case ((330) 740-2208); never-married parents establish it in the Juvenile Division ((330) 740-2278); and the Mahoning County CSEA ((330) 740-2600) opens IV-D cases and enforces orders through wage withholding.

How do I set or change child support in Mahoning County, Ohio?

Run the official Ohio Child Support Computation Worksheet (2024 Income Shares), then file it with your case. Married or divorcing parents address support inside the divorce or dissolution in the Domestic Relations Division; never-married parents establish support with a parentage/custody complaint or a Petition for Order of Support in the Juvenile Division ($140 filing fee). To change an existing order, file the Form 28 motion in the division that issued it — a Domestic Relations post-decree motion is $100, a Juvenile support modification is $100 — or ask the Mahoning County CSEA ((330) 740-2600) for an administrative review. Support changes generally require a 10% change or other qualifying basis (R.C. 3119.79).

Mahoning County child support, calculated and enforced right

Every child-support number in Ohio runs through the statewide 2024 Income Shares worksheet (R.C. Chapter 3119) — there is no Mahoning County formula. What changes locally is where you file: married or divorcing parents set support inside the Domestic Relations case ((330) 740-2208), never-married parents establish it in the Juvenile Division ((330) 740-2278), and the Mahoning County CSEA ((330) 740-2600) opens IV-D cases and collects by wage withholding. Gavvl Law prepares the worksheet, files in the right place, and works on a flat fee with payment plans.

The worksheet, run with the real numbers. Support turns on both parents' gross incomes plus health-insurance and child-care figures fed into the official Ohio calculator. We build the signed worksheet accurately and file it with your pleadings, because a sloppy worksheet is the fastest way to end up with a support figure that doesn't fit your finances.
Filed in the division that can hear it. Married parents address support inside the divorce or dissolution; never-married parents open it in the Juvenile Division on a $140 complaint plus the $15 OLAF fee. We route your case to the right court from the start so you aren't refiling later in the wrong division.
Modification or CSEA review, whichever fits. To change an order you file the Form 28 motion ($100) in the division that issued it, or ask the Mahoning County CSEA for a free administrative review — and Ohio generally requires a 10% change or other qualifying basis (R.C. 3119.79). We tell you which path is faster for your facts.

The Mahoning County CSEA at 345 Oak Hill Avenue in Youngstown is what turns a paper order into money that actually arrives — wage withholding, tax intercept, license suspension, and credit reporting, all with no court-cost deposit. We open your IV-D case and keep enforcement moving so support is collected and distributed, not just ordered.

Flat-fee options

Flat-fee limited scope: we draft and file the support motion (establish, modify, or terminate). The court filing fee is billed separately and this does not include in-court representation.

Establish child support: $950
Modify child support: $950
Terminate child support: $950

Prefer full representation? An Ohio attorney can carry the entire case on a $3,500 retainer.

Split any flat fee with Gavvl Direct — our in-house plan at 19% APR, $500 minimum — on a 60%-down schedule of 18 weekly, 8 bi-weekly, or 4 monthly payments, or full financing where work begins once 60% is paid. Affirm, Klarna, and PayPal Pay Later are also available through LawPay.
