a Most people think common law marriage means “living together long enough that you automatically become married.”
But that’s not true—at least not in most parts of the United States.
Common law marriage is a legally recognized marriage without a ceremony, license, or wedding. It’s based on the couple’s actions and intentions—not paperwork. Only a few U.S. states still recognize it, and each has its own rules.
Understanding this unique form of marriage is important, especially for couples living together or planning their future. Whether it’s taxes, health decisions, or property rights, common law marriage can significantly shape your legal life.
✔ What Is Common Law Marriage?
A common law marriage is a legally valid marriage created through a couple’s mutual agreement to live as spouses, without the traditional formalities.
A common law marriage is just as legally binding as a ceremonial marriage.
This means:
- You cannot “break up” informally
- You must get a legal divorce to end it
- Property rights and spousal support laws apply
- Both partners gain legal protections
In other words, no wedding doesn’t mean no marriage—if the law recognizes it.
✔ States That Recognize Common Law Marriage
As of today, only a handful of states fully recognize the creation of new common law marriages:
States that currently allow common law marriage:
- Colorado
- Iowa
- Kansas
- Montana
- Oklahoma (under limited circumstances and still debated)
- Texas
- Utah (recognizes “marriage by agreement”)
- District of Columbia
States that previously allowed it and still recognize old common law marriages made before the cutoff date:
- Georgia
- Ohio
- Florida
- Indiana
- Pennsylvania
Even if your current state doesn’t allow it, the U.S. Constitution requires states to honor valid common law marriages created elsewhere.
✔ Requirements for a Valid Common Law Marriage
There is no universal rule—each state sets its own standards. However, most states require the following:
- Mutual Agreement to Be Married
Both partners must intend to be married now, not someday in the future.
- Cohabitation
Living together helps demonstrate commitment, though time length is not the main factor (there’s no “7-year rule”).
- Holding Yourself Out as Married
This means representing yourselves to others as a married couple.
Examples:
- Calling each other husband/wife
- Joint bank accounts
- Shared last name
- Joint leases or property
- Filing joint taxes
- Listing each other as “spouse” on forms
Courts look at the total picture, not just one item.
✔ Myths About Common Law Marriage
❌ Myth 1: Living together automatically makes you married
Truth: No state requires or counts years of cohabitation alone.
❌ Myth 2: Having kids together creates common law marriage
Truth: Children do not automatically create marriage status.
❌ Myth 3: You can “choose later” if you were common law married
Truth: Courts decide based on evidence—not personal claims afterward.
✔ Benefits and Protections of a Common Law Marriage
A valid common law marriage gives the same legal protections as a ceremonial marriage:
Legal Benefits:
- Inheritance rights
- Right to spousal Social Security benefits
- Tax benefits
- Medical decision-making authority
- Spousal insurance coverage
- Property and asset rights
Legal Responsibilities:
- Must go through divorce court to separate
- May owe spousal support
- Must divide marital property
If legally married—even without a wedding—you cannot avoid obligations by claiming “we never had a ceremony.”
✔ How to End a Common Law Marriage
Because it is legally recognized, ending it requires a formal divorce, just like any other marriage.
The court decides:
- Property division
- Spousal support
- Child custody
- Child support
You cannot simply walk away.
✔ How to Avoid an Unintended Common Law Marriage
If you live together and do NOT want to be considered married, you should:
- Avoid referring to each other as “spouse”
- Keep finances separate
- Do not file joint taxes
- Consider signing a cohabitation agreement
- Avoid listing each other as “spouse” on official forms
Clarity protects both partners.
