Ohio does not recognize domestic partnerships at the state level. There is no statewide registry, no statute granting unmarried couples rights comparable to marriage, and no legal status the state itself will confer on a couple that chooses not to marry. What Ohio does have is a patchwork of municipal registries — more than a dozen cities and counties have created them by local ordinance — and a set of private legal tools that couples can use to build their own protections under Ohio contract and probate law.
Why Ohio Doesn’t Recognize Domestic Partnerships
The block is constitutional. Article XV, Section 11 of the Ohio Constitution, adopted in 2004, says only a union between one man and one woman may be a valid marriage, and it goes further: the state “shall not create or recognize a legal status for relationships of unmarried individuals that intends to approximate the design, qualities, significance or effect of marriage.”1Justia Law. Ohio Constitution Article XV Section 11 – Marriage That second clause is what has kept any statewide domestic partnership framework off the table, for same-sex and opposite-sex couples alike.
The 2015 U.S. Supreme Court decision in Obergefell v. Hodges, which originated in Ohio, required the state to license and recognize same-sex marriages.2Justia U.S. Supreme Court Center. Obergefell v. Hodges, 576 U.S. 644 (2015) It did not require Ohio to create a separate domestic partnership category, and Section 11’s restriction on marriage-adjacent legal statuses is still on the books.
What Local Registries Actually Do
Where the state is silent, some Ohio cities and counties have stepped in. Jurisdictions with domestic partner registries include Athens, Cincinnati, Cleveland, Cleveland Heights, Columbus, Dayton, Lakewood, Oberlin, Toledo, and Yellow Springs, along with Cuyahoga County and Franklin County. Each lets a couple formally record the relationship within that municipality.
A municipal certificate is useful for a narrow set of things. It documents the relationship for local purposes and for private entities that choose to recognize it. Some employers require a municipal certificate before extending health insurance or other benefits to an employee’s partner. It can also help with practical matters like hospital visitation or gym membership enrollment.
What a municipal certificate does not do is more important. It has no legal force outside the issuing city’s borders, and it does not override state law. It grants no rights to inherit property, no next-of-kin status, no ability to file taxes jointly, and no automatic authority to make medical decisions. A couple who relies on the certificate alone is unprotected in every situation that tends to matter most.
How to Register in an Ohio City
Each city sets its own rules, but the general steps are similar across Ohio.
- Government-issued photo identification for both partners, such as an Ohio driver’s license or passport.
- Proof of a shared primary residence — a joint lease, a utility bill in both names, or similar documentation.
- Evidence of financial interdependence. Columbus, for example, requires applicants to meet at least four of several listed criteria, such as joint property ownership, a joint bank account, or shared responsibility for household expenses.3City of Columbus.

- Notarization. Both partners appear together before a notary with the completed declaration, and each affirms under oath that the information is true.3City of Columbus. Domestic Partnership Registry – Frequently Asked Questions
You then submit the form and filing fee to the designated city office, usually the City Clerk or City Auditor. Fees vary: Cincinnati charges $45,4City of Cincinnati, Ohio.

What You Lose Without Additional Legal Planning
Ohio law treats unmarried partners as legal strangers to each other, no matter how long you’ve lived together or whether you hold a municipal certificate. Two default rules cause most of the damage.
The first is intestate succession. If your partner dies without a will, Ohio’s statute directs property first to a surviving spouse, then to children, then parents, then siblings, and outward through extended family.8Ohio Legislative Service Commission. Ohio Revised Code Section 2105.06 An unmarried partner appears nowhere in that order. Without a will, trust, or survivorship deed naming you, you inherit nothing.
The second is medical decision-making. Ohio law does not automatically give an unmarried partner authority to make healthcare decisions for an incapacitated partner. Providers look to the legal next of kin — a spouse, adult child, or parent. Your partner has no guaranteed role unless the paperwork is already in place.
Federal Benefits a Registry Cannot Reach
Some readers assume a municipal certificate opens the door to federal spousal benefits. It doesn’t. These programs turn on legal marriage, and no city registry can change that.
- Tax filing status. The IRS determines filing status by whether you were legally married on the last day of the tax year. Unmarried partners each file as single, or head of household if they qualify independently.9Internal Revenue Service. Filing Status
- Estate tax marital deduction. The unlimited deduction for property passing at death applies only to a surviving spouse, not to a domestic partner.10Office of the Law Revision Counsel. 26 USC 2056 – Bequests to Surviving Spouse
- Gift tax. Spouses can make unlimited tax-free gifts to each other. Unmarried partners are limited to the annual exclusion, $19,000 per recipient in 2026, with anything above that counting against the lifetime exemption.11Internal Revenue Service.

- Social Security survivor benefits. Available to a surviving spouse (or former spouse in some cases), dependent children, and dependent parents. Domestic partners are not eligible.12Social Security Administration. Survivors Benefits
- Family and Medical Leave Act. Federal law defines spouse as husband or wife and excludes domestic partners, so FMLA-protected leave to care for a partner is not available.13Office of the Law Revision Counsel. 29 U.S. Code 2611 – Definitions14U.S. Department of Labor. Fact Sheet 28L – Leave Under the FMLA When You and Your Spouse Work for the Same Employer
- Federal Employees Health Benefits. Domestic partners are not eligible family members; only legally married spouses qualify.15U.S. Office of Personnel Management. Will Domestic Partners Be Eligible for Coverage Under a Self Plus One Enrollment
Some private employers voluntarily extend benefits to domestic partners, and a municipal certificate is often the documentation they require. That’s an employer choice, not a legal entitlement.
The Documents That Actually Protect You
Because the state won’t do it for you, the meaningful protections for unmarried couples in Ohio come from a set of private legal documents. Each one closes a specific default rule that leaves partners exposed.
Healthcare Power of Attorney
A healthcare power of attorney names your partner as the person authorized to make medical decisions if you can’t make them yourself. Any competent Ohio adult can create one and name any competent adult as agent. The document must be signed, dated, and either witnessed by two adults or acknowledged before a notary.16Ohio Legislative Service Commission. Ohio Revised Code Section 1337.12
HIPAA Authorization
Federal privacy rules let providers share information with someone involved in your care, but the rules leave room for discretion, especially if you’re unconscious.17U.S. Department of Health & Human Services. Disclosures to Family and Friends A written HIPAA release naming your partner removes the ambiguity.
Living Will
A living will sets out your preferences for life-sustaining treatment if you develop a terminal condition or enter a permanently unconscious state. Any adult of sound mind can create one under Ohio law. If you want to authorize the withholding of nutrition and hydration in a permanently unconscious state, that authorization has to appear conspicuously — in capital letters, bold type, or a separately checked provision.18Ohio Legislative Service Commission. Ohio Revised Code Section 2133.02
Funeral and Burial Declaration
Under Ohio Revised Code Chapter 2108, you can designate any adult to make funeral, burial, and anatomical donation decisions on your behalf. The declaration must be signed and either notarized or witnessed by two adults.19Ohio Legislative Service Commission. Ohio Revised Code Chapter 2108 Without it, all next of kin share equal authority and must agree, which can shut a partner out entirely.
Financial Power of Attorney
A durable financial power of attorney authorizes your partner to manage bank accounts, pay bills, and handle investments if you can’t. Ohio’s statutory form covers a broad range of financial matters that you can grant individually.20Ohio Legislative Service Commission. Ohio Revised Code Section 1337.60 – Statutory Form Power of Attorney Without it, your partner would have to petition a court for guardianship.
Will or Trust
Because Ohio’s intestate statute gives an unmarried partner nothing, a will or trust naming your partner is the only reliable way to pass assets to them at death.8Ohio Legislative Service Commission. Ohio Revised Code Section 2105.06
Survivorship Deed for Real Estate
For a home you own together, Ohio’s survivorship tenancy statute is a powerful tool. When two people hold title as survivorship tenants, the survivor automatically takes full title without probate. The deed has to clearly express that intent; listing both names is not enough.21Ohio Legislative Service Commission. Ohio Revised Code Section 5302.20 If only one partner is on the deed and dies without a will naming the other, the property passes to that partner’s legal heirs.
Shared Property Agreement
A written agreement covering vehicles, furniture, savings, and other jointly acquired assets defines each partner’s share and how things get divided if the relationship ends. Ohio does not apply marital property rules to unmarried couples, so this contract is what a court would look to.
Ending a Municipal Registration
If the relationship ends or you decide to marry, formally terminate any municipal registration. Typically one or both partners file a notice of termination with the city office that issued the certificate. In Cleveland Heights, for example, the partnership ends when the notice is filed, with no court proceeding required. The partnership also ends automatically on the death of either partner.
After termination, notify any third party — an employer, an insurance company — that received a copy of your declaration and extended benefits on the strength of it. Otherwise you could be on the hook for benefits paid out after the partnership ended.
