Common Law Marriage Ohio: Does the State Recognize It?

Last verified: October 30, 2026 against ORC 3105.12 (version effective May 7, 2004) and the Supreme Court of Ohio decision in Nestor v. Nestor

Does Ohio have common law marriage? Not anymore. Common law marriage Ohio couples relied on before 1991 is closed to anyone starting a relationship today, no matter how long you live together or whether you share a last name, a lease or a bank account.

This page explains what Ohio law says, who may still be treated as married, how a court decides, and what to do if you need to prove a marriage or end one.

Does Ohio recognize common law marriage?

Ohio recognizes only the older ones. The state law says that, on and after October 10, 1991, a marriage must be solemnized by an authorized officiant and follow the licensing rules in ORC Chapter 3101 (ORC 3105.12(B)(1)).

Two groups are still protected. The first is a common law marriage formed in Ohio before October 10, 1991 that has not ended. The second is a common law marriage formed in a state that recognizes it, as long as it has not ended and is not invalid under ORC 3101.01 (ORC 3105.12(B)(2) and (B)(3)).

The Ohio Revised Code page for this section still shows the May 7, 2004 version as the current one, and no enacted bill changing it was found at the time of this check.

Is Ohio a common law state? A short timeline

Ohio was a common law state for most of its history, and courts treated an informal marriage as just as real as a ceremony. The legislature closed that door in the 1990s.

Date	Event
1984	The Supreme Court of Ohio decides Nestor v. Nestor (15 Ohio St.3d 143), the leading case on what must be proved.
1984 to 1991	Ohio courts keep accepting common law marriage when the couple meets those elements.
October 10, 1991	Ohio stops allowing new common law marriages under ORC 3105.12.
May 7, 2004	Current version of ORC 3105.12 takes effect (House Bill 272, 125th General Assembly), spelling out which older and out-of-state marriages still count.
October 30, 2026	No change to the cutoff. Couples formed after 1991 still need a license and a ceremony.

How many years do you have to live together for common law marriage in Ohio?

There is no number of years, and living together never creates a marriage on its own. The “seven years” idea is a myth in Ohio, and it does not matter if you have been together two years or twenty.

For a couple together since 2005, for example, there is no common law claim at all. A court would treat each of you as a single person, even if you share a home, a mortgage and children.

Common law marriage Ohio requirements for older couples

A couple who claims a pre-1991 marriage must prove three things (Nestor v. Nestor, 1984), and the court requires clear and convincing evidence of each.

• A present agreement to be married. Both of you must have agreed, in the present tense, to take each other as spouses. This is the essential element. A plan to marry someday is not enough.
• Cohabitation. You lived together openly as spouses, not in secret.
• Reputation. The people you deal with, such as family, neighbors, coworkers and your church, knew you as husband and wife.

Both people also have to be legally able to marry. A person who still had a living spouse could not form a valid common law marriage, and age and family-relationship limits in ORC 3101.01 apply too.

Courts look at things such as joint tax returns, insurance and lease forms, the names on mail and wills, rings, and what people said. Words matter: calling each other “my girlfriend” or “my partner” on official papers can hurt a claim.

Does Ohio recognize a common law marriage from another state?

Yes, if it was valid where it was formed and it has not ended (ORC 3105.12(B)(3)). The rules of the other state decide whether the marriage was created.

A handful of states still allow it, including Colorado, Kansas, Montana, Iowa, Rhode Island, Texas and Utah, each with its own requirements. The list changes over time, so check the other state’s current law. If you moved to Ohio from one of them after forming a marriage there, Ohio treats you as married. If you only visited, an Ohio court would want strong proof that you met that state’s test.

Myths and facts

Myth	Fact
“After seven years, we are married.”	Ohio has no time rule. Years together do not create a marriage.
“We share a bank account and a lease, so we are common law spouses.”	Shared bills are only evidence. Ohio no longer lets a new couple form this marriage.
“Ohio ended it, so older couples lost it.”	Ohio common law marriages from before October 10, 1991 remain valid until ended by death, divorce, dissolution or annulment.
“A common law couple can just split up.”	If the marriage is valid, you need a court order to end it, the same as any other marriage.
“A girlfriend or boyfriend who lives with me can claim my property.”	Without a valid marriage, there is no spousal property right, no spousal support and no automatic inheritance.

Common law divorce in Ohio

If your marriage is valid, you end it the same way as any other: by divorce or dissolution in the court of common pleas. There is no separate “common law divorce” form.

The person asking for a divorce must have lived in Ohio for at least six months right before filing (ORC 3105.03). In a contested case, the first question is often whether a marriage exists at all. You may need to prove the three elements before the judge can divide property or order support.

Once a court finds a valid marriage, normal divorce rules apply (see our guide to divorce laws in Ohio), including property division, spousal support and custody (ORC Chapter 3105 and ORC 3109.04). If the court finds no marriage, there is nothing to divorce, and the couple is treated as two unmarried people.

What if you are not legally married?

You can still protect yourself, but you must do it on paper. Unmarried partners in Ohio have no automatic marital rights, so a few documents carry real weight.

• Property and debts. Put names on the deed or title, and use a written agreement for shared purchases.
• Children. An unmarried father is not presumed to be the legal father. Signing an acknowledgment of paternity and getting a court order on custody and support matter (ORC 3111.03 and ORC 3111.23).
• Inheritance. If you die without a will, Ohio’s intestacy rules favor a surviving legal spouse (ORC 2105.06). An unmarried partner needs a will or beneficiary designation.
• Health and money decisions. Sign a health care power of attorney and a durable financial power of attorney.

Ohio’s domestic violence law is a separate case. It protects a “person living as a spouse,” so an unmarried partner who lives with you, or lived with you within the past five years, can still ask for a civil protection order (ORC 3113.31).

Real Ohio scenarios

• Together since 1988 in Columbus. You told everyone you were married, never had a ceremony, and used the same last name. A court could find a valid pre-1991 marriage if you prove an agreement, cohabitation and reputation. You would need a divorce to end it.
• Together since 2009 in Cleveland. You share a home and a child. You are not married. Without a ceremony and license, you have no spousal rights, but a court can still set custody and support for the child.
• Married in Colorado, then moved to Cincinnati. If your Colorado common law marriage was valid and never ended, Ohio recognizes it. You still need a divorce to end it.
• Dating, then one partner dies. Without a will, the surviving partner may be left out. That is why a lawyer often asks whether a valid marriage exists before an estate is opened.

How to marry in Ohio the legal way

The licensed route is quick. Both of you appear at the probate court in the county where either of you lives and apply for a license, and the probate judge issues it if there is no legal barrier (ORC 3101.05).

The marriage must then be solemnized by a person the law allows, such as an ordained minister or a judge (ORC 3101.08). The statute for the license does not set a waiting period. Check your county probate court for fees and hours.

Columbus, Cleveland and Cincinnati

Marriage law is state law, so the rule is the same in Columbus, Cleveland, Cincinnati and every other Ohio city. Your county probate court issues the license, and the county court of common pleas handles any divorce.

Frequently asked questions

Does Ohio have common law marriage?

Not for new couples. Ohio stopped allowing common law marriages formed on or after October 10, 1991 (ORC 3105.12). Older Ohio marriages that never ended, and valid ones formed in other states, are still honored.

Is Ohio a common law marriage state?

No. Ohio is not a state where a couple can form a new common law marriage today. The state still recognizes certain older ones, but anyone who wants to marry now needs a probate court license and a solemnized ceremony under ORC Chapter 3101.

Is there a common law marriage in Ohio after seven years?

No. Ohio has no seven-year rule or any other time rule. Even decades of living together do not create a marriage for a couple who started after October 10, 1991. Only a license and ceremony do.

Is common law marriage legal in Ohio if we moved here from Colorado or Texas?

It can be. Ohio honors a common law marriage that was valid where it was formed and has not ended (ORC 3105.12(B)(3)). The other state’s rules decide whether it was created, and Ohio will want proof.

How do I prove an older Ohio common law marriage?

You must show, by clear and convincing evidence, a present agreement to be married, open cohabitation and a reputation as spouses (Nestor v. Nestor). Tax returns, insurance forms, leases, wills, letters and witness testimony all help.

Can I get a common law divorce in Ohio?

There is no separate common law divorce. If a court finds that your marriage is valid, you end it through the same divorce or dissolution process as any couple, after meeting the six-month residency rule in ORC 3105.03.

What rights do I have if I am not married in Ohio?

You have no automatic spousal rights to property, support or inheritance. You can protect yourself with deeds, wills, powers of attorney and, for children, paternity and custody orders. Domestic violence law still covers a person living as a spouse.
