Moving in with a romantic partner is a major life step. Whether it’s about convenience, finances, or testing long-term compatibility, cohabitation is increasingly common. But in Texas, living together can come with unexpected legal consequences if your relationship crosses the line from “roommates” into what Texas law recognizes as an informal (common law) marriage.
For many couples, the key issue is simple—but often misunderstood: what you intend may matter less than what you do.
Informal Marriage Under Texas Family Law
Texas is one of the few states that still recognizes informal marriage. Under Texas Family Code § 2.401, a court may determine that an informal marriage exists if all three of the following elements are proven:
- The couple agreed to be married
- They lived together in Texas as married
- They represented to others that they were married
When these elements are met, the relationship is treated the same as a formal marriage. That means Texas divorce laws, community property rules, and spousal rights apply, even without a wedding or marriage license.
How Couples Accidentally Create a Common Law Marriage
Many informal marriage disputes start with one partner saying, “We were never married.” Unfortunately, courts look less at labels and more at conduct.
- Calling each other “husband” or “wife”
- Filing joint tax returns
- Listing a partner as a spouse on insurance or employment forms
- Maintaining joint bank accounts or shared debt
- Introducing each other as married to friends, family, or coworkers
While each action alone may seem harmless, together they can establish an informal marriage under Texas law.
Roommates vs. Common Law Marriage: Where the Line Is Drawn
Roommates or Unmarried Partners
- Live together for convenience
- Maintain separate finances
- Avoid holding themselves out as married
- Do not agree to be spouses
Common Law Marriage
- An agreement or understanding to be married
- Cohabitation as a married couple
- Representation to others that the couple is married
Once an informal marriage exists, ending the relationship typically requires a formal Texas divorce.
When a Cohabitation Agreement Is a Smart Idea
If you plan to live together, a Texas cohabitation agreement can provide important legal protection.
When Should You Have a Cohabitation Agreement?
- One or both partners own real estate
- There is a large difference in income or assets
- You plan to purchase property together
- One partner contributes financially to property titled in the other’s name
- You want clear evidence that no informal marriage was intended
The best time to sign a cohabitation agreement is before moving in together.
What a Cohabitation Agreement Can Do
- State clearly that the parties are not married
- Define ownership of property and responsibility for debts
- Set expectations for shared household expenses
- Outline what happens if the relationship ends
- Reduce the risk of informal marriage claims later
What Happens After a Breakup?
Under Texas Family Code § 2.401(b), if a couple separates and no legal action is filed within two years, the law presumes there was no agreement to be married. That presumption, however, can be challenged with evidence—making disputes costly and stressful.

Frequently Asked Questions About Living Together in Texas
Does living together automatically create a common law marriage in Texas?
No. Living together alone does not create a common law marriage in Texas. Under Texas Family Code § 2.401, a couple must agree to be married, live together as a married couple, and represent to others that they are married.
What is an informal (common law) marriage under Texas law?
An informal marriage, also known as a common law marriage, is a legally recognized marriage in Texas that does not require a ceremony or marriage license. If the legal requirements are met, the relationship carries the same legal rights and responsibilities as a formal marriage.
How do couples accidentally create a common law marriage?
Couples may unintentionally create an informal marriage by referring to each other as “husband” or “wife,” filing joint tax returns, listing each other as spouses on insurance or employment forms, or introducing themselves as married to friends, family, or coworkers.
What is a cohabitation agreement in Texas?
A cohabitation agreement is a written contract between unmarried partners who live together. It clarifies financial responsibilities, property ownership, and confirms that the couple does not intend to be married.
When should unmarried couples get a cohabitation agreement?
Unmarried couples should consider a cohabitation agreement before moving in together—especially when one partner owns property, there is a significant income difference, or the couple plans to share expenses or purchase assets together.
Can a cohabitation agreement prevent common law marriage claims?
While no agreement can override all conduct, a properly drafted cohabitation agreement can be strong evidence that the parties did not intend to be married. This may reduce the risk of common law marriage claims in Texas.
Do you need a divorce to end a common law marriage?
Yes. If a Texas court determines that a common law marriage exists, it must be legally ended through a formal divorce—not simply by moving out or separating.
