Common Law Marriage States: Are You Accidentally Married?

Many couples believe that living together for 7 years automatically creates a marriage. This is a persistent myth. However, in 7 states and Washington D.C., you can become legally married without a license if you meet specific criteria. The catch? There is no such thing as “Common Law Divorce.” Once established, you need a court order to split. Here is the corrected 2026 list, including important changes for South Carolina.

1. The Rule: “Holding Out” is Key

It is rarely about the clock. It is about your public behavior.

The 3-Prong Test
To be married by common law, you usually must:
1. Cohabitation: Live together in that specific state.
2. Capacity: Be single and over 18 (legal to marry).
3. Holding Out: Tell the community you are married. (e.g., Introducing partner as “husband/wife,” putting both names on a deed).

2. Which States Allow It? (2026 List)

Verify your state carefully. South Carolina is no longer on the active list.

Status Jurisdictions Nuance
Full Recognition
(Active)
Colorado, Iowa, Kansas, Montana, Rhode Island, Texas, Utah, Washington D.C. Oklahoma is often cited, but case law is complex and conflicting.
Grandfathered
(Past Only)
South Carolina (Pre-July 2019), Alabama (Pre-2017), PA (Pre-2005). New couples cannot form one. Valid only if started before the cutoff date.
No Recognition California, New York, Florida, Illinois, etc. Living together for 50 years creates zero marital rights.

3. Timeline: The “Forever” Trap

There is no “Common Law Divorce.” Once you cross the line, you are locked in until a judge releases you.

Planning Note
If you live in a common law state (like Texas or D.C.) and do NOT want to be married, it is generally critical to sign a written “Cohabitation Agreement” explicitly stating that you are not married and have no intention to be.

4. Strategy: “Full Faith and Credit”

What happens if you move?

  • The Rule: Under the U.S. Constitution, states must recognize valid legal acts of other states.
  • The Scenario: You establish a valid common law marriage in Texas. You then move to California (which does not allow common law marriage).
  • The Result: California MUST recognize your Texas marriage. You are still married. If you split up in California, you must get a legal divorce under California law.

5. Warning: The “Tax Return” Mistake

One checkbox can change your life.

⛔ Filing Jointly

Filing a federal tax return as “Married Filing Jointly” is the strongest proof of common law marriage.

  • The IRS: To file jointly, you must be legally married.
  • The Effect: By checking that box, you are legally declaring to the federal government that you are married. You cannot later claim “we were just dating” when one partner demands alimony.

6. Frequently Asked Questions

Is there a 7-year rule?
No. This is a myth. You could live together for 20 years in Texas and not be married if you never “held out” as a couple. Conversely, you could be married after 1 day if you agree and announce it publicly.
What about New Hampshire?
New Hampshire has a very limited rule: it only recognizes common law marriage posthumously. This means you are only “married” for inheritance purposes after one partner dies.
