To prove a common law marriage in Texas, you have two options: file a signed Declaration of Informal Marriage with your county clerk, or show in court that you and your partner agreed to be married, lived together in Texas as spouses, and represented to others that you were married. Texas Family Code § 2.401 requires all three of those elements to have existed at the same time, and no single element carries the claim on its own.1State of Texas. Texas Family Code Section 2.401 – Proof of Informal Marriage
Texas law sets no minimum time period. The persistent belief that living together for seven years automatically creates a marriage has no basis in the statute. You could theoretically satisfy all three elements in a matter of weeks, and you could live with someone for thirty years without ever forming a common law marriage.2Texas State Law Library. Common Law Marriage
Proving the Agreement to Be Married
This is the element that sinks most cases. You need to show a present, mutual intent to be married right now, not a plan to marry later. “We should get married next year” is a future intention. “We are married,” said and treated as true by both partners, is what the statute requires.
Because couples rarely put this agreement in writing, courts look at conduct. Evidence that tends to prove a marital agreement includes:
- Buying a home together or signing a joint mortgage
- Naming each other as beneficiaries on life insurance or retirement accounts
- Making joint financial decisions that only a married couple would typically make
- Direct testimony from one or both partners about the agreement itself
The strongest cases combine direct testimony about the agreement with financial and personal decisions that back it up over time. A judge or jury is far more likely to credit your account of the agreement when your everyday choices matched it.
Proving You Lived Together as Spouses in Texas
Living together “as spouses” means more than sharing rent. Roommates share a roof. Spouses share a life. Courts want to see evidence of an actual marital household, not just a common address.
Useful evidence includes joint leases or mortgage documents, shared utility accounts, mail addressed to both partners at the same address, and testimony from neighbors or friends who observed daily life in the home. Shared household responsibilities and joint domestic routines all help. The question is whether the arrangement looked like a marriage from the inside, not whether you both used the same address on your driver’s licenses.
The cohabitation also has to have taken place in Texas. Time spent living together in another state does not satisfy this element on its own.
Proving You Held Out as Married
The third element, often called “holding out,” requires that you consistently presented yourselves to the outside world as a married couple. Occasional or ambiguous references will not carry the point. Courts look for a pattern.
Persuasive evidence includes:
- Filing joint federal or state tax returns
- Using the same last name
- Maintaining joint bank accounts or credit cards
- Introducing each other as “my husband” or “my wife” to friends, coworkers, or medical providers
- Listing each other as spouses on insurance policies, school forms, or emergency contacts
Social media can cut both ways. A post referring to your partner as your spouse supports the claim. A post from the same period calling them your boyfriend or girlfriend undercuts it. Consistency across time and audiences is what a court weighs, not any single document.
The Two-Year Deadline After Separation
If you and your partner separate and stop living together, § 2.401(b) gives you two years to bring a legal proceeding to prove the marriage. If you don’t file within that window, the law presumes you were never married in the first place.1State of Texas. Texas Family Code Section 2.401 – Proof of Informal Marriage
The presumption is rebuttable, so it is still possible to overcome it with strong enough evidence after the deadline. In practice, that is a much harder and more expensive fight than acting inside the two years. If property, custody, inheritance, or benefits are on the line, treat the two-year clock as a hard deadline.
Filing a Declaration of Informal Marriage: The Shortcut
Texas offers a much simpler alternative to proving each element in court. A signed, sworn Declaration of Informal Marriage filed with the county clerk works as official proof of the marriage, similar to a traditional marriage certificate.3State of Texas. Texas Family Code Section 2.402 – Declaration and Registration of Informal Marriage
The form is prescribed by the bureau of vital statistics and available at any county clerk’s office. Each party provides full name, address, date of birth, place of birth, and Social Security number. The sworn oath states that, on or about a specific date, you agreed to be married, lived together as spouses, and represented to others that you were married. Both parties also confirm they are not related within the prohibited degrees and that neither is currently married to anyone else.3State of Texas. Texas Family Code Section 2.402 – Declaration and Registration of Informal Marriage
Both parties must appear together at the clerk’s office with valid government-issued identification such as a driver’s license, state ID, or passport. Filing fees vary by county but generally run between $36 and $47.
If filing a declaration is an option, take it. Couples who file avoid the cost and uncertainty of proving each element later, and the declaration eliminates any dispute about whether the marriage exists. That matters enormously if one partner later denies the relationship or dies without a will.
Who Is Eligible to Form One
Some couples cannot form a common law marriage no matter what the evidence shows.
Both parties must be at least 18. A minor cannot enter an informal marriage or sign a declaration, and parental consent does not change that.1State of Texas. Texas Family Code Section 2.401 – Proof of Informal Marriage
Neither party can be currently married to someone else. Entering an informal marriage while still legally married to a prior spouse can support a bigamy charge, a third-degree felony in Texas punishable by two to ten years in prison and a fine of up to $10,000.4State of Texas. Texas Penal Code Section 25.01 – Bigamy It also leaves the first spouse’s marital property rights intact, which can pull assets accumulated with the second partner back into the first marriage.
Close relatives cannot marry. The prohibition covers parents and children by blood or adoption, siblings including half-siblings, and aunts or uncles and their nieces or nephews, along with the equivalent adoptive relationships.5State of Texas. Texas Family Code FAM 6.201 – Consanguinity
Same-sex couples can form a common law marriage in Texas. Section 2.401 still uses the phrases “man and woman” and “husband and wife,” but the U.S. Supreme Court’s decision in Obergefell v. Hodges (2015) established a constitutional right to marry regardless of sex, and the federal Respect for Marriage Act of 2022 replaced statutory language defining marriage as between a man and a woman with language recognizing any marriage between two individuals valid under state law.
Why the Proof Matters
Once established, a common law marriage carries exactly the same legal weight as a ceremonial marriage. There is no lesser tier.
Texas is a community property state. Property acquired by either spouse during the marriage belongs to both spouses equally, regardless of who earned the money or whose name is on the title.6State of Texas. Texas Family Code Section 3.002 – Community Property With an informal marriage, the start date determines which assets fall into the community pot. Without a declaration on file, that date can itself become the central fight.
A recognized common law spouse inherits the same way any other surviving spouse does under Texas law. If your partner dies without a will, you are entitled to a share of the estate. If the will leaves you nothing, you may still have protections including a homestead allowance. Exercising any of those rights requires first proving the marriage, which is why couples who never filed a declaration often end up litigating the three elements after one partner has died.
Federal agencies generally follow Texas on the question. The IRS treats a valid Texas common law marriage the same as any other marriage for tax purposes and continues to recognize it even if the couple moves to a state that does not permit common law marriages.7Internal Revenue Service. Revenue Ruling 2013-17 The Social Security Administration recognizes common law marriages for survivor and spousal benefits, and prefers signed statements from both spouses (if living) along with statements from two blood relatives; if one spouse has died, the survivor submits a statement along with statements from two blood relatives of the deceased.8Social Security Administration. 20 CFR 404.726 – Evidence of Common-Law Marriage USCIS recognizes a common law marriage for naturalization and spousal visa purposes if it was valid in the state where it was established.9U.S. Citizenship and Immigration Services. Marriage and Marital Union for Naturalization
One last point people miss: there is no informal divorce. A common law marriage can only be dissolved through the same formal divorce process as a ceremonial marriage. If you simply walk away, you are still legally married, you cannot remarry without risking a bigamy charge, and your property rights remain tied to your spouse.
