Common law marriage is a legally recognized marriage created without a traditional marriage license or ceremony when a jurisdiction’s requirements are met. Simply living together for a certain number of years does not create one. The key questions are where the relationship was formed, whether both partners intended to be married, and how they presented themselves publicly. 

That distinction matters because a legally married couple can acquire rights and responsibilities related to divorce, property, taxes, inheritance, and benefits. 

Question 2026 U.S. answer 
Does living together automatically create a marriage? No 
Is there a universal seven-year rule? No 
What usually matters? Legal capacity, mutual intent, cohabitation, and conduct showing a marital relationship 
Where can new informal marriages still be formed? Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and Washington, D.C. 
Is Utah different? Yes. Utah uses a court or administrative process to recognize certain unsolemnized marriages 
Does New Hampshire have a limited rule? Yes. Its rule applies after three years of qualifying cohabitation that continues until one partner dies 
Can proof matter after separation or death? Yes, especially for property, inheritance, benefits, and divorce 
Does a valid marriage normally require a divorce to end? Yes 

The current state-by-state picture is more complicated than a simple yes-or-no list. Some jurisdictions allow new informal marriages, while others recognize them only in limited situations or protect relationships created before specific cutoff dates. 

Key Takeaways 

  • Simply sharing a home for years does not make two people legally married. 
  • There is no nationwide rule stating that seven years of cohabitation creates a marriage. 
  • State law determines whether an informal marital relationship can be created. 
  • Evidence may include tax filings, insurance records, leases, financial documents, and statements from people who knew the couple. 
  • If a valid marriage exists, simply separating usually does not end the legal relationship. 
  • Moving to another state normally does not erase a marriage that was valid where it was formed. 
  • Same-sex couples can qualify under the same applicable state rules. 

What Common Law Marriage Means Legally

A common-law or informal marriage is not a lesser form of marriage once it has been legally established. In a state that recognizes it, the relationship can carry many of the same legal consequences as a ceremonial marriage. 

The absence of a wedding, marriage license, or marriage certificate is what makes this type of relationship unusual. It does not mean that its legal effects are informal. 

This is also why cohabitation and marriage should not be treated as synonyms. Two people can share a home, raise children, combine finances, and remain legally unmarried.

The Seven-Year Rule Is a Myth 

One of the most persistent misconceptions is that living together for seven years automatically turns a couple into legal spouses. 

There is no general U.S. seven-year requirement. Instead, states that recognize informal marriage apply their own legal requirements. 

Texas provides a useful example. The length of time a couple lives together does not, by itself, create an informal marriage. Specific requirements involving mutual agreement, cohabitation, and representing themselves to others as married may apply.  Also worth reading: Colorado Child Support.

Time can still matter as evidence. Years of consistent conduct may make a marital claim easier to prove, but time alone is not the legal test. 

Which States Recognize New Informal Marriages in 2026? 

Current legal rules generally identify seven states plus Washington, D.C., where couples may still establish new informal marriages for general purposes: 

  • Colorado 
  • Iowa 
  • Kansas 
  • Montana 
  • Oklahoma 
  • Rhode Island 
  • Texas 
  • Washington, D.C. 

Each jurisdiction applies its own requirements, so recognition does not mean the rules are identical everywhere. 

Utah deserves separate treatment. Its law allows a court or administrative process to recognize certain marriages that were not formally solemnized. The requirements can include legal capacity, cohabitation, mutual marital obligations, and a public reputation as spouses. 

New Hampshire is narrower. Its rule applies in certain circumstances when qualifying partners cohabit and are generally known as spouses for three years, with that relationship continuing until one partner dies. 

Several other states preserve older relationships established before their laws changed. 

State Older relationships that may still be recognized 
Alabama Those formed before January 1, 2017 
Georgia Those formed before January 1, 1997 
Ohio Those formed before October 10, 1991 
Pennsylvania Those formed on or before January 1, 2005 
South Carolina Those formed before July 24, 2019 

These cutoff rules make the date and place where the relationship was formed especially important. 

What Do Couples Usually Have to Prove? 

The exact legal tests vary, but several factors appear repeatedly. 

A person claiming an informal marital relationship may need evidence showing that: 

  • both partners had the legal capacity to marry; 
  • both intended to enter a present marital relationship; 
  • they lived together where required; 
  • they consistently represented themselves as spouses; and 
  • their financial or personal records supported that representation. 

No single document always decides the issue. 

Possible evidence may include joint tax filings, leases signed as spouses, jointly purchased property, insurance coverage, beneficiary designations, loan applications, and representations made when applying for benefits. Statements from relatives, friends, or other people who knew the couple may also help establish how the relationship was presented publicly. 

A Practical Proof Checklist 

Evidence What it may help show 
Joint tax returns The couple represented themselves as married 
Insurance records One partner identified the other as a spouse 
Lease, deed, or mortgage records Shared housing and how the relationship was described 
Joint loan or bank records Financial integration 
Beneficiary forms How the partners described their relationship 
Statements from relatives or friends The couple’s public reputation as married 
Written declaration or court order Formal proof where state law provides that option 

The strongest evidence is usually consistent. Records describing two people as married may support a claim, while repeated records describing them as unmarried may work against it. 

What Rights and Responsibilities Can Follow? 

Once an informal marriage is valid, its legal consequences can extend well beyond a couple’s living arrangement. 

Divorce and Property 

A valid marriage may require a formal divorce to end it. Property division, marital debts, and possible spousal support can then become part of the case. Once legally established, an informal marriage may carry the same marital status as a formally licensed marriage in jurisdictions that recognize it.

Federal Taxes 

A marriage that is legally valid under applicable state law may also affect federal tax status. That means determining marital status can have consequences beyond the couple’s personal description of their relationship.

Inheritance and Survivor Benefits 

Proving marriage can become especially important after one partner dies. A surviving partner may need to establish marital status before claiming rights under state inheritance law or seeking benefits that depend on legal spousal status. 

This is one reason couples should not leave their legal status uncertain when significant property, retirement benefits, or estate rights are involved. 

What Happens When the Relationship Ends? 

A breakup does not automatically dissolve a legally created marriage. 

If a court determines that the couple was married, a divorce may be required to end the relationship and settle related property or support issues. 

The difficult part is often proving whether a marriage existed in the first place. 

In some jurisdictions, additional rules may affect how long a person has to assert that an informal marriage existed after separation. These rules are state-specific and should not be treated as nationwide deadlines. If a relationship ends and either person believes marital rights exist, seeking state-specific legal advice early can help prevent later disputes. 

What If You Move to Another State? 

Moving does not normally dissolve a valid marriage. 

A state that does not permit couples to form new informal marriages may still recognize a marriage that was validly established in another jurisdiction. 

Proof may become the more difficult issue. Without a conventional marriage certificate, a spouse may need documents or testimony to establish when and where the marriage was performed. 

Anyone facing probate, divorce, taxes, or benefits after an interstate move should confirm the rules that apply in the new state. 

Do the Rules Apply to Same-Sex Couples? 

Yes. Same-sex couples can establish an informal marriage when they meet the applicable state requirements. 

The same core questions generally apply: legal capacity, mutual intent, conduct, location, and the requirements of the jurisdiction involved. 

The legal test is based on whether the requirements for marriage were satisfied, not on whether the couple is same-sex or opposite-sex. 

What to Do If Your Marital Status Is Unclear 

Start with the law of the state where you and your partner lived when you believe the marriage began. Gather tax records, leases, deeds, insurance documents, beneficiary forms, financial records, and other documents showing how both partners described the relationship. Then compare those facts with the state’s current legal requirements. 

If the answer could affect a home, divorce, inheritance, taxes, retirement benefits, or Social Security, consider speaking with a family-law attorney in the relevant state. Getting a clear answer early can be safer than trying to establish marital status during a breakup or probate dispute. 

FAQs 

Does living together for seven years make you legally married? 

No. There is no nationwide seven-year rule. A state that recognizes informal marriage applies its own legal requirements, and cohabitation alone is not enough. 

Can a common law marriage end automatically when we separate? 

No, not if a valid marriage already exists. A legally established marriage generally continues until it is ended through divorce, annulment where applicable, or death. 

Can unmarried partners file a joint federal tax return because they live together? 

Living together by itself does not create married tax status. Whether a couple is legally married depends on the applicable marriage laws. 

What happens if one partner dies before the marriage is documented? 

The surviving partner may have to prove that a valid marriage existed. Evidence can become especially important in inheritance or survivor-benefit claims. 

Can a couple document their status without having a wedding? 

Sometimes. Certain jurisdictions allow qualifying couples to document or formally establish an informal marriage through a declaration, court proceeding, or another authorized process. 
The exact procedure depends on state law.
