Hire Gavvl Law for a Union County legal separation

Legal separation lets the Union County Court of Common Pleas - Domestic Relations Division at 215 W 5th St in Marysville divide property and debt and set support and parenting orders while you stay legally married — a fit for religious, insurance, or financial reasons. It uses the same income and property affidavits as a divorce, plus the local Classification Form and UCD1, and with children the co-parenting class applies. Gavvl Law prepares the complaint and the orders, at a flat fee for a straightforward separation.

Court orders without ending the marriage. A legal separation divides property and debt and sets support and parenting time, but neither spouse can remarry and the marriage continues. We make sure the orders match why you chose separation over divorce, and preserve the option to change course toward a divorce later.
The same affidavits, plus Union's local forms. You file the Income and Expenses affidavit and the Property and Debt affidavit, and with children add the parenting and health-insurance affidavits, the support worksheet, and a IV-D application — all under the local Classification Form and UCD1. We assemble the full packet the Marysville Clerk expects so it isn't returned at the counter.
The deposit and class, confirmed up front. Union's legal-separation deposit may differ from a divorce, so we confirm the current amount with the Clerk at (937) 645-3015, and with minor children both parents must complete the co-parenting class before the final hearing. We handle both so there are no surprises mid-case.

We file legal separations at the Union County Domestic Relations Division in Marysville and know it can divide property and set support while you remain married, subject to Ohio's six-month residency rule.
