A marriage without a license is legally recognized only in the small group of states that still allow common law marriage, and even there it requires more than just living together. Everywhere else, skipping the license means the law does not treat you as married, no matter how long you have been a couple, how public your relationship is, or whether a religious ceremony took place. That gap matters for property, inheritance, taxes, federal benefits, and medical decisions.
When an Unlicensed Marriage Is Still Legal
Common law marriage lets two people become legally married without a license or ceremony, but only a handful of states permit it today. Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and Utah are among the states that still recognize new common law marriages, along with the District of Columbia. New Hampshire recognizes it only for inheritance purposes. Several other states honor common law marriages formed before a cutoff date but no longer allow new ones.
The requirements look similar across recognizing states. Both partners must agree to be married, live together, and hold themselves out publicly as a married couple. Courts scrutinize that last element the hardest. Using the same last name, calling each other spouses, filing joint tax returns, and listing each other on insurance policies all count as evidence. Simply living together for a certain number of years, contrary to a common myth, does not by itself create a common law marriage anywhere.
Once validly established, a common law marriage carries the same legal force as a licensed one. Dissolving it requires a formal divorce, with property division and possible spousal support. Separation alone does not end it. And most states will honor a valid common law marriage created in another state, even if the recognizing state does not allow its own residents to form one.
What You Lose Without a Recognized Marriage
If you live outside a common law marriage state and never got a license, the law treats you as two unrelated individuals. That has consequences that most couples do not think about until something goes wrong.
Property and Inheritance
If one partner dies without a will, intestate succession laws control who inherits, and in every state those laws give inheritance rights to legal spouses and blood relatives. An unmarried partner, no matter how long the relationship lasted or how intertwined the finances were, is not an heir under intestacy law. The surviving partner would need to prove a recognized common law marriage or rely on other legal tools set up in advance.
Property division on breakup is equally exposed. In a recognized marriage, community property or equitable distribution rules apply and courts split assets under set principles. Unmarried partners have no such framework; whoever holds title generally keeps the asset, unless a written agreement says otherwise.
Taxes
The IRS recognizes a marriage for federal tax purposes if the state where it was entered into recognizes it.1Internal Revenue Service. Publication 501 (2025) Dependents Standard Deduction and Filing Information Couples in a valid common law marriage can file jointly and access every tax benefit available to licensed married couples. Couples without a legally recognized marriage each file as single individuals.
The bigger tax gap sits in gifts and estates. Married spouses can transfer unlimited assets to each other during life or at death without triggering federal gift or estate tax.2Office of the Law Revision Counsel. 26 USC 2056 Bequests Etc to Surviving Spouse The same unlimited deduction applies to gifts to a spouse who is a U.S. citizen.3Office of the Law Revision Counsel. 26 USC 2523 Gift to Spouse Unmarried partners get none of it. Gifts above the annual exclusion count against the giver’s lifetime estate and gift tax exemption, and anything one partner leaves the other at death is part of the taxable estate with no marital deduction to shelter it.4Internal Revenue Service.

Federal Benefits
Social Security survivor benefits, spousal retirement benefits, and lump-sum death payments all require legal marriage. The Social Security Administration will recognize a common law marriage if the couple lives in a state that recognizes it or if the common law marriage began in such a state.5Social Security Administration. Evidence of Common-Law Marriage An unmarried partner in a state that does not recognize common law marriage has no claim to a deceased partner’s Social Security benefits, even after decades together.
The Department of Veterans Affairs uses the same rule for survivor benefits, dependency and indemnity compensation, and spousal healthcare eligibility: it recognizes a common law marriage if the veteran’s state of residence does.6VA.gov. Important Information on Marriage U.S. Citizenship and Immigration Services will accept a common law marriage as the basis for a spousal petition if the marriage is valid where it was formed, applying a preponderance-of-the-evidence standard and expecting supporting documentation like joint tax returns, shared leases or mortgages, commingled accounts, and birth certificates of children born to the couple.7U.S. Citizenship and Immigration Services.

Medical Decisions
This is where the absence of a marriage license can turn a crisis into a legal fight. Without a legal marriage, your partner has no automatic authority to make medical decisions if you become incapacitated. Courts often prefer blood relatives over unmarried partners when appointing a healthcare decision-maker.
Hospital visitation itself is somewhat protected. Federal regulations require any hospital, long-term care facility, or critical access hospital participating in Medicare or Medicaid to let patients designate their own visitors, including domestic partners and friends, and prohibit discrimination based on the visitor’s relationship to the patient.8U.S. Department of Health & Human Services. FAQs on Patient Visitation at Certain Federally Funded Entities and Facilities Visitation is not the same as authority, though. Being allowed in the room does not mean you can consent to surgery or direct a treatment plan.
HIPAA adds another layer. The privacy rule permits providers to share information with a “close personal friend” identified by the patient, but that depends on the patient having identified the partner in advance or being conscious enough to do so.9U.S. Department of Health & Human Services. Disclosures to Family and Friends If your partner is unconscious and you are not listed as an authorized contact, the hospital may refuse to share information with you.
Religious Ceremonies Are Not a Substitute
A wedding performed by a religious leader, following cultural traditions and celebrated by the community, can feel entirely legitimate and still leave the couple with no legal marriage. Civil law governs who is legally married in every state. A religious ceremony may satisfy the solemnization requirement, but skipping the marriage license typically means the state does not recognize the union.
Most states allow clergy to officiate and list religious leaders among those authorized to solemnize a marriage. Authorization to solemnize is separate from the license requirement, however. The license is the legal foundation; the ceremony completes it. Without the license, even a ceremony performed by a recognized officiant in full compliance with religious custom generally has no legal effect.
The Putative Spouse Doctrine
A few states offer a narrow safety net for people who genuinely believed their marriage was valid when it was not. Under the putative spouse doctrine, someone who entered a marriage in good faith, not knowing about a defect like a missing license, a prior undissolved marriage, or an invalid ceremony, can still claim some or all of the property rights of a legal spouse. The doctrine exists in states including Colorado, California, Illinois, and Louisiana. The claimant must have sincerely and reasonably believed the marriage was legally valid when it was entered into. This does not help a couple who knowingly skipped the license.
How to Prove a Common Law Marriage
If you are relying on common law marriage, the burden of proving it falls on you, and it is heavier than most people expect. There is no certificate to point to, so courts and federal agencies look for a combination of documents and sworn statements.
The U.S. Office of Personnel Management sets a standard that is representative of what other agencies want. To claim federal retirement benefits as a common law spouse, OPM requires the claimant’s own sworn affidavit stating when and where the couple agreed to be married, plus affidavits from at least two other people, ideally one from the spouse’s family and one from outside it, describing the relationship. On top of those affidavits, OPM wants at least two additional types of verification: jointly owned property records, tax returns showing married filing status, joint bank account statements, health insurance enrollment, or joint loan applications.10OPM.gov. RI 38-86 Proof of Marriage for the Purpose of Obtaining Retirement Benefits The Social Security Administration takes a similar approach, preferring signed statements from the surviving spouse plus two blood relatives of the deceased, with substitutes allowed if blood relatives are unavailable.5Social Security Administration. Evidence of Common-Law Marriage
The practical lesson is the same across agencies: build the paper trail while you are both alive and together. Proving the marriage after one partner dies or becomes incapacitated is far harder.
Legal Tools to Protect an Unlicensed Relationship
Couples who choose not to get a marriage license, or who live where common law marriage is not available, have tools to protect each other. None replicate every right of a legal marriage, but together they close the largest gaps.
- Will. A will lets you leave property to any person you choose, including an unmarried partner. Without one, state intestacy rules distribute your assets to legal relatives, and an unmarried partner receives nothing.
- Beneficiary designations. Life insurance policies, retirement accounts, and payable-on-death bank accounts pass directly to the named beneficiary, bypassing probate and intestacy entirely. Any person can be named, regardless of marital status. These designations override a will, so keep them current.
- Joint tenancy with right of survivorship. Titling real estate or bank accounts this way means the surviving owner automatically inherits the other’s share without probate. The ownership type must be stated on the deed; most jurisdictions default to tenancy in common, which has no automatic survivorship.
- Healthcare proxy and HIPAA authorization. A healthcare proxy (also called a medical power of attorney) lets your partner make medical decisions if you cannot. A signed HIPAA authorization names your partner as someone who can access your medical records. A living will adds your own treatment preferences.
- Durable power of attorney. Authorizes your partner to handle financial matters, including paying bills, managing accounts, and dealing with insurance, if you are incapacitated.
- Cohabitation agreement. Functions like a contract between unmarried partners, spelling out who owns what, how expenses and debts are shared, and how property gets divided if the relationship ends. Courts treat it like any other contract: it needs to be written, signed voluntarily, and free of provisions like attempts to limit future child support obligations.
These tools will not give you married filing jointly tax status, Social Security spousal benefits, or immigration sponsorship. They do address the most immediate risks around property, inheritance, and medical emergencies.
Children of Unmarried Parents
Children’s legal rights do not depend on whether their parents have a marriage license. Courts decide custody based on the child’s best interests regardless of the parents’ marital status, looking at each parent’s relationship with the child, ability to provide a stable home, and any history of abuse or neglect.
Paternity is where unmarried couples run into extra steps. Most states presume that a child born to a married couple is the husband’s child. That presumption does not apply to unmarried fathers. To establish legal parental rights, an unmarried father typically signs a Voluntary Acknowledgment of Paternity at the hospital after birth or goes through a court paternity proceeding. Signing a VAP carries the same legal force as a court judgment of paternity and sets the basis for custody, visitation, and child support orders. It also gives the child access to Social Security, health insurance, military benefits, and inheritance rights through the father. Signing a VAP waives the right to have paternity decided by a court, so it is a serious legal step rather than routine paperwork.
Child support obligations exist whether or not the parents were ever married. Courts calculate support from both parents’ income, the child’s needs, and state guidelines. Failure to pay court-ordered child support across state lines can bring federal criminal charges: a misdemeanor carrying up to six months in prison if payment is overdue, or a felony with up to two years if the amount exceeds $10,000 or is more than two years past due.11U.S. Department of Justice.

If you live in a state that recognizes common law marriage and intend to rely on that status, start the paper trail now. File joint tax returns, list each other on insurance, and keep affidavits from family and friends who know the relationship. If you live anywhere else, the legal system will not read your relationship the way your community does, and the documents above are what stand between you and the default rules.
