Legal Separation in Ohio: Grounds, Court Orders and Divorce (2026)

Yes. Ohio lets either spouse file a complaint for legal separation in the court of common pleas, and the court may grant it for the causes listed in Ohio Revised Code (R.C.) 3105.17(A). A legal separation decree lets the court deal with property, spousal support and children, and it does not bar either spouse from later filing for or obtaining a divorce (R.C. 3105.17(B)).

Jurisdiction scope: This article covers legal separation under Ohio Revised Code Chapter 3105, mainly sections 3105.03, 3105.10, 3105.17, 3105.171, 3105.18 and 3105.21, with the Supreme Court of Ohio's Legal Separation bench card (September 2024). It does not cover dissolution or divorce procedure in depth, how spousal support or child support amounts are calculated, inheritance rights during a separation, or other states' law. For divorce, see Ohio divorce laws.

Does Ohio allow legal separation?

Yes. R.C. 3105.17 creates the action and lets either spouse start it:

"Either party to the marriage may file a complaint for divorce or for legal separation, and when filed the other may file a counterclaim for divorce or for legal separation."

A legal separation is handled by the court of common pleas. It produces a court decree that can settle property, spousal support and arrangements for the children, without a divorce. The version of R.C. 3105.17 relied on here took effect March 23, 2023 (Senate Bill 210, 134th General Assembly).

Grounds for legal separation in Ohio

R.C. 3105.17(A) lists the causes for which the court may grant a legal separation. It opens:

"The court of common pleas may grant legal separation on a complaint or counterclaim, regardless of whether the parties are living separately at the time the complaint or counterclaim is filed, for the following causes:"

The ten causes are:

• Either party had a husband or wife living at the time of the marriage.
• Willful absence for one year.
• Adultery.
• Extreme cruelty.
• Fraudulent contract.
• Gross neglect of duty.
• Habitual drunkenness.
• Imprisonment of the adverse party in a state or federal correctional institution at the time the complaint is filed.
• On the application of either party, living separate and apart without cohabitation for one year (R.C. 3105.17(A)(9)).
• Incompatibility, unless denied by either party.

This list closely tracks the divorce grounds in R.C. 3105.01, but it does not include the divorce ground based on one spouse obtaining a divorce outside Ohio. The Supreme Court of Ohio's Legal Separation bench card lists the same grounds and states that a corroborating witness is required in all cases. The bench card is a summary for judges and states that it is not binding law.

Residency and where to file

Ohio's six-month state residency rule is written for other actions. R.C. 3105.03 provides that "the plaintiff in actions for divorce and annulment shall have been a resident of the state at least six months immediately before filing the complaint."

For legal separation, the same section says:

"Actions for legal separation shall be brought in the proper county for commencement of actions pursuant to the Rules of Civil Procedure."

The Supreme Court of Ohio's Legal Separation bench card summarizes this as "No specific residency requirement [R.C. 3105.03]." The same card also refers to 90 days of residence in the county before filing. That comes from Ohio Civil Rule 3(C)(9), which makes the county where the plaintiff has lived for at least 90 days immediately before filing one of the counties where a legal separation case may be filed. Civil Rule 3(C) also lists other proper counties, such as the county where the other spouse lives. The domestic relations court or clerk can confirm where your case belongs.

What the court can order in a legal separation

A legal separation decree can address property, spousal support, the children and dower rights. The table below lists the orders this page covers.

The property rule turns on a request. R.C. 3105.171(B) provides that "in legal separation proceedings upon the request of either spouse, the court may, determine what constitutes marital property and what constitutes separate property."

The support rule matters for long separations. R.C. 3105.18 states:

"In an action brought solely for an order for legal separation under section 3105.17 of the Revised Code, any continuing order for periodic payments of money entered pursuant to this section is subject to further order of the court upon changed circumstances of either party."

For how support amounts are set, see Ohio alimony laws. For custody and parenting time, see Ohio child custody laws, and for support calculations, Ohio child support laws.

Property acquired after the decree

Two definitions in R.C. 3105.171 fix the timeline. In a legal separation action, the period for counting marital property runs to the date of the final hearing (R.C. 3105.171(A)(2)(a)).

After the decree, new property belongs to the spouse who acquires it. R.C. 3105.171(A)(6)(a)(iv) treats as separate property:

"Any real or personal property or interest in real or personal property acquired by one spouse after a decree of legal separation issued under section 3105.17 of the Revised Code;"

Moving from legal separation to divorce

The sections this page covers do not describe a step that converts a legal separation into a divorce. Instead, R.C. 3105.17 keeps both paths open. R.C. 3105.17(B) provides:

"The filing of a complaint or counterclaim for legal separation or the granting of a decree of legal separation under this section does not bar either party from filing a complaint or counterclaim for a divorce or annulment or obtaining a divorce or annulment."

Living separate and apart without cohabitation for one year is both a divorce ground (R.C. 3105.01(J)) and a legal separation ground (R.C. 3105.17(A)(9)). Separately, R.C. 3105.17(C) lets the court terminate a legal separation decree on a motion signed by both spouses.

Legal separation vs. divorce in Ohio

A legal separation decree is not a divorce. R.C. 3105.17(B) assumes that either spouse may still go on to obtain a divorce after the decree.

The main practical differences this page covers are the residency rules (six months in Ohio for divorce, the proper county under the Civil Rules for legal separation), and property division, which the court must order in a divorce but may order in a legal separation only on request. This page does not cover how a legal separation affects inheritance rights or eligibility to remarry. For divorce grounds and procedure, see Ohio divorce laws.

Frequently Asked Questions

Is there legal separation in Ohio?

Yes. Under R.C. 3105.17, either spouse may file a complaint for legal separation in the court of common pleas, and the other spouse may counterclaim for legal separation or divorce.

What are the grounds for legal separation in Ohio?

R.C. 3105.17(A) lists ten causes, including adultery, extreme cruelty, willful absence for one year, gross neglect of duty, habitual drunkenness, one year living apart without cohabitation, and incompatibility unless denied by either party.

Do you have to live apart to file for legal separation in Ohio?

No. R.C. 3105.17(A) allows legal separation regardless of whether the parties are living separately when the complaint is filed. Living apart for one year without cohabitation is itself one of the listed causes (R.C. 3105.17(A)(9)).

Can you get spousal support during a legal separation in Ohio?

Yes. On either spouse's request and after dividing property, the court may order spousal support under R.C. 3105.18, and in an action brought solely for legal separation, a continuing periodic support order stays subject to change on changed circumstances of either party.

Does legal separation divide property in Ohio?

It can. On either spouse's request, the court may determine marital and separate property and divide it equitably (R.C. 3105.171(B)). Property one spouse acquires after the decree is that spouse's separate property.

Can a legal separation turn into a divorce in Ohio?

A legal separation does not bar either spouse from later filing for or obtaining a divorce (R.C. 3105.17(B)). The court can also end a legal separation decree on a motion signed by both spouses (R.C. 3105.17(C)).
