Legal Separation in Mercer County, Ohio

Mercer County, Ohio · Celina · General Division

A legal separation lets the court divide property and debt and order custody, parenting time, and support without ending the marriage. People use it for religious, insurance, or personal reasons, or when Ohio's 6-month residency for divorce isn't met yet. It's filed in the General Division.

How do I file for legal separation in Mercer County, Ohio?

File the same complaint forms as a divorce — UDRF 6 (no children) or UDRF 7 (with children), marked for legal separation — with Affidavits 1–2 (and 3–4, the DR 3/DR 4 worksheet, and DR 10 if there are minor children) plus the SO 1 restraint order, with the Clerk of Courts in the General Division (Loc.R. 15.01). The filing is treated under the divorce/DR fee schedule. The A-OK Parenting Program applies when minor children are involved. You stay legally married and cannot remarry, but the court can divide property and order support and a parenting schedule. A legal separation can later be converted to a divorce.

How to File Legal Separation in Mercer County

Prepare the complaint forms. Use UDRF 6 (no children) or UDRF 7 (with children) marked for legal separation, with Affidavits 1–2 (add 3–4, the worksheet, and DR 10 for minor children) and the SO 1 restraint order (Loc.R. 15.01).

Attend the hearing. The court divides property and debt and orders custody, parenting time, and support without ending the marriage. A legal separation can later be converted to a divorce if either spouse wants to end the marriage.

Mercer County Practice Notes

You stay married. A legal separation divides property and orders support and a parenting schedule, but you remain legally married and cannot remarry. Common reasons include keeping health insurance or other benefits, religious convictions, or not yet meeting Ohio's 6-month residency for divorce.
Mercer uses statewide AND local forms. Mercer County divorce and dissolution filings combine the statewide Uniform Domestic Relations Forms with local DR and SO forms — most notably the SO 1 restraint order and SO 2 parenting-time schedule. Filers who bring only a state packet are often surprised by the local forms, so use the Mercer bskpdf form library together with the Supreme Court forms.
A-OK Parenting Program is required (divorce/dissolution). Parents of minor children in a divorce or dissolution must complete the A-OK Parenting Program ($30/person) before the final hearing (Common Pleas Loc.R. 21.02). It runs the 4th Tuesday of January, March, May, July, September, and November, 6:00–9:00 p.m., in Room 303. You are registered automatically at filing and the court mails your date. The requirement comes from the DR local rules, so unmarried-parent custody cases in Juvenile Court are generally not ordered into A-OK.
