To file for legal separation in Ohio, submit a Complaint for Legal Separation at the Domestic Relations Court in the Ohio county where you meet residency. You or your spouse must have lived in Ohio for at least six months immediately before filing, and you must have lived in the filing county for at least 90 days. The complaint keeps your marriage legally intact while asking a court to divide property, set support, and establish custody for any minor children.
Residency and Where to File
Ohio has two residency thresholds, and both must be met. You or your spouse needs six months of Ohio residency immediately before filing. On top of that, you need 90 days in the county where you file.1Cuyahoga County Domestic Relations Court. Cuyahoga County Legal Separation Process If you and your spouse live in different Ohio counties, either county works as long as the 90-day requirement is satisfied there.
The case is filed in the Domestic Relations Court, not general civil court. Ohio uses the term “Complaint” rather than “Petition,” so the form you want will be labeled Complaint for Legal Separation.2Cuyahoga County Domestic Relations Court. Complaint for Legal Separation – Cuyahoga County
Choosing a Ground for the Separation
Your complaint must state a legal ground. Ohio recognizes ten:
- Incompatibility, which cannot be used if the other spouse denies it
- Living separate and apart without cohabitation for one uninterrupted year
- Extreme cruelty
- Gross neglect of duty
- Adultery
- Habitual drunkenness
- Willful absence of the other spouse for one year
- Fraudulent marriage contract
- Imprisonment of the other spouse in a state or federal correctional institution
- Bigamy, meaning either spouse was already married at the time of the marriage
Most uncontested cases rely on incompatibility because it does not require proving fault. The fault-based grounds matter when a spouse denies incompatibility or when documented fault is relevant to spousal support.3LAWS.com. Ohio Revised Code 3105-17 – Complaint for Divorce or Legal Separation
Documents You Will Need
The Complaint for Legal Separation is the core filing. It identifies both spouses, states the ground, and tells the court what relief you are asking for: property division, spousal support, custody, and child support.
Several supporting documents go with it. Most counties require a Case Designation Sheet alongside the complaint. Financial disclosure is standard; Franklin County, for instance, requires separate affidavits for income and expenses and for property.4Franklin County Law Library. Legal Separation without Children Your county’s forms may be similar or identically named. If you have minor children, a Parenting Proceeding Affidavit is required as well, disclosing any other custody cases involving those children.
Gathering Financial Records Before You Fill Out the Forms
Before you sit down with the affidavits, pull recent pay stubs, tax returns, bank and investment statements, mortgage documents, vehicle titles, and records of outstanding debts such as credit cards or student loans. Having these in front of you makes the forms much faster to complete and cuts down on the errors that slow a case.
Parenting Plan for Minor Children
If you have children under 18, the court expects a parenting plan. A workable plan sets out a residential schedule for weekdays, weekends, and holidays, and explains how you and your spouse will make major decisions about education, medical care, and extracurricular activities. Agreement on these terms before you file will move the case along faster than leaving them for the judge.
Filing the Complaint and Paying the Fee
Take the completed packet to the clerk of courts at your county’s Domestic Relations Court. Some Ohio counties also accept filings by mail or through an electronic filing portal, but filing in person lets the clerk flag missing forms on the spot.
You pay a filing fee at submission. The amount varies by county; Cuyahoga County charges $200. If you cannot afford the fee, file a Poverty Affidavit, also called a Civil Fee Waiver Affidavit, asking the court to waive it.1Cuyahoga County Domestic Relations Court.

Serving Your Spouse
After filing, your spouse must be formally notified. The court calls this service. One of the filing forms asks how you want service handled. Common options are delivery by a county sheriff’s deputy, a private process server, or in some cases certified mail. Telling your spouse informally is not enough; the court needs proof of service through an approved method before the case can move forward.
What Happens After You File
Once your spouse has been served, the case moves into the court’s timeline. Expect at least one preliminary hearing or status conference where the judge reviews the case and schedules next steps. Many Ohio domestic relations courts strongly encourage or require mediation, especially when children are involved. Mediation lets both spouses negotiate property division, support, and parenting terms with a neutral third party before a judge decides for them.
If you reach a full agreement, you submit a written settlement. The judge reviews it for fairness and, if children are involved, for the children’s best interests. Once approved, the court issues a Decree of Legal Separation. That decree is a binding court order governing property, support, and custody until the court modifies it or a divorce supersedes it.
If you cannot agree on every issue, the unresolved ones go to trial. The judge hears evidence and issues a decree with terms the court determines are equitable. Even a partial agreement helps, because the judge only has to rule on what is left.
One Thing to Know Before You File
Filing for legal separation in Ohio does not prevent either spouse from later filing for divorce or annulment.3LAWS.com. Ohio Revised Code 3105-17 – Complaint for Divorce or Legal Separation If your spouse responds to your complaint by filing a counterclaim for divorce, the case can shift into a divorce proceeding even though that was not your intent. If preserving the marriage is a reason you chose separation over divorce, talk with an attorney before filing so you go in with a realistic sense of what the other side may do.
