Most states do not recognize domestic partnerships. Only a handful run statewide registries, which means couples in roughly 40 states have no state-level path to legal recognition short of marriage. If you live in one of those states, your options are a local city or county registry (where one exists), private legal documents, or marriage itself.
States Without Statewide Domestic Partnership Recognition
The states that do maintain statewide registries open to new couples are California, Maine, Nevada, Oregon, and the District of Columbia. New Jersey registers partnerships but only for couples where both partners are 62 or older, and Washington requires at least one partner to be 62 or older. Hawaii offers civil unions and a separate reciprocal beneficiary status. Illinois has an active civil union statute. Colorado’s civil union law was ruled unconstitutional in 2015 and has not been replaced.
Every other state falls outside statewide recognition. That includes Texas, Florida, Georgia, Ohio, Pennsylvania, and Michigan, none of which ever created a program. It also includes Connecticut, Delaware, and New Hampshire, which converted their civil unions into marriages after legalizing same-sex marriage and closed their registries. Wisconsin closed its same-sex domestic partnership registry in April 2018, though already-registered couples kept their status. Rhode Island and Vermont did the same: no new registrations, existing ones preserved. Mississippi has no recognition at either the state or local level.
If your state is not on the active list above, assume you have no statewide domestic partnership option.
Why Most States Stopped Offering Partnerships
Domestic partnerships and civil unions were originally the main legal route for same-sex couples before marriage was available. After the Supreme Court’s 2015 decision in Obergefell v. Hodges required every state to allow and recognize same-sex marriages,1Legal Information Institute (LII) / Cornell Law School. Obergefell v. Hodges many legislatures treated their partnership statutes as redundant. Some gave couples a deadline to convert to marriage or dissolve. Washington, Connecticut, Delaware, and New Hampshire automatically converted partnerships into marriages when couples missed the cutoff. The map has been shrinking ever since, not growing.
Local Registries in Non-Recognition States
No statewide program does not always mean no registry at all. Hundreds of cities and counties run their own, especially in states where the legislature never acted. Phoenix maintains an active registry open to same-sex and opposite-sex couples. Detroit, Ann Arbor, and other Michigan municipalities register partners. Cities and counties in Florida, Georgia, Missouri, and Louisiana offer similar programs.
The reach is narrow. A local registry might make your partner eligible for municipal employee health coverage or secure hospital visitation rights inside that jurisdiction. It carries no weight at the state level and none outside the city or county that issued it. A Phoenix registration means nothing in Tucson.
What Non-Recognition Actually Costs You
Even in states that do run registries, domestic partners hit a federal ceiling: the IRS, Social Security, and federal labor law treat them as unmarried. In a non-recognition state, you face both the federal gap and the state gap at once.
Taxes
Registered domestic partners cannot file federal returns as married filing jointly or married filing separately. The IRS treats them as unmarried, so each partner files as single or, if eligible, head of household.2Internal Revenue Service. Answers to Frequently Asked Questions for Registered Domestic Partners and Individuals in Civil Unions The joint-filing tax brackets, higher standard deduction, and spousal credit thresholds are unavailable.
Health Insurance
When a married employee adds a spouse to employer coverage, the employer’s share of the premium is tax-free. When an employee adds a domestic partner who is not a tax dependent, that employer contribution is treated as taxable “imputed income” to the employee. The couple pays income tax on coverage a married couple gets tax-free. Self-funded employer health plans regulated under federal law are not required to offer domestic partner coverage at all, no matter what state law says.
Family and Medical Leave
The federal Family and Medical Leave Act lets eligible employees take up to 12 weeks of unpaid, job-protected leave to care for a spouse with a serious health condition. “Spouse” is defined by reference to state marriage law, including common-law and same-sex marriages.3eCFR. 29 CFR 825.122 – Definitions of Covered Servicemember, Spouse, Parent, Son or Daughter Domestic partners are not covered. If your partner is hospitalized, federal law does not protect your job for taking time off to care for them.
Social Security and Retirement
Married spouses can claim Social Security spousal benefits worth up to 50% of a partner’s benefit, plus survivor benefits. Domestic partners have no automatic right to either. The Social Security Administration says some people in non-marital legal relationships may qualify under certain circumstances and directs them to contact the agency,4Social Security Administration. Do I Qualify for Benefits as a Spouse if I Am Now in, or the Surviving Spouse of, a Civil Union, Domestic Partnership, or Other Non-Marital Legal Relationship? but the path is nothing like the automatic one married couples have.
Federal pension law references spouses throughout its survivor-benefit provisions and does not mention domestic partners.5Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits A married spouse has a legal right to pension survivor benefits unless they waive it. A domestic partner has no such right under federal law.
Moving to a Non-Recognition State
A partnership registered in California or Oregon has no guaranteed force in Texas, Georgia, or any of the roughly 40 states without statewide recognition. After Obergefell, marriages are portable to every state. Partnerships are not. Illinois recognizes civil unions and substantially similar relationships from other states, but reciprocity provisions like that are the exception.
The Full Faith and Credit Clause requires states to honor each other’s court judgments, but its reach over statutes and legal statuses like partnerships is weaker, and courts give states significant freedom to apply their own law instead.6Constitution Annotated | Congress.gov | Library of Congress. ArtIV.S1.1 Overview of Full Faith and Credit Clause A state with no partnership law of its own has little reason to enforce another state’s. If you relocate, assume your partnership gives you no protection in the new state until a local attorney confirms otherwise.
Building Protections Without a Partnership
In a state that doesn’t recognize domestic partnerships, you build your legal relationship through private documents. These rely on contract and estate law that every state honors, which actually makes them more portable than a registry in some respects. The essential pieces:
- A cohabitation agreement setting out how you and your partner handle property, shared expenses, debts, and division of assets if you separate.
- A durable power of attorney for finances, so your partner can manage accounts and pay bills if you become incapacitated. Without one, banks will not let your partner touch your accounts.
- A healthcare power of attorney, so your partner can make medical decisions if you cannot communicate. Hospitals default to blood relatives, and an unmarried partner has no standing without this document.
- A will or trust naming your partner. State intestacy laws pass assets to blood relatives when there is no will, and an unmarried partner inherits nothing by default no matter how long you lived together.
- Updated beneficiary designations on life insurance, retirement accounts, and payable-on-death bank accounts. These override whatever your will says, so they have to match.
Legal fees for the full bundle vary, but budget at least several hundred dollars, more depending on complexity and location. If you are raising children together, you also need to pursue formal legal recognition of both parents, usually through second-parent adoption where it is available, rather than relying on a court to recognize a de facto parent relationship after a dispute. The paperwork is what the legal system responds to. Length of relationship and shared life are not substitutes.
Common-Law Marriage in a Few States
A small number of states still grant full marital status to couples who live together, hold themselves out as married, and meet the state’s requirements, without a marriage license. Colorado, Iowa, Kansas, Montana, South Carolina, Texas, and Utah currently recognize common-law marriages. New Hampshire recognizes them only for inheritance purposes after one partner dies. Rhode Island and Oklahoma have upheld common-law marriages through case law.
Where it exists, common-law marriage delivers what partnerships cannot: joint federal tax filing, Social Security spousal benefits, FMLA coverage, and portability to every state. The requirements are strict, proof can be contested after the fact, and most states do not recognize it at all. If you think you qualify, document your intent and talk to an attorney now, because an unproven claim is worth nothing in a hospital or a probate court.
