If you built a life with a partner but never had a wedding, Texas may already consider you married. A common law marriage in Texas, which the law calls an informal marriage, can exist without a license or ceremony when the couple’s agreement and the way they lived together meet the state’s test. Once it exists, it carries the same property rights as any other marriage and ends only through a divorce. WSM Law represents women in San Antonio and across Bexar County, including in San Antonio divorce cases that start with proving the marriage.

Under Section 2.401 of the Texas Family Code, an informal marriage can be proved by a signed declaration or by evidence that all three of these elements were present together:
The same section sets two limits. No one under 18 can enter an informal marriage, and no one who is still married to someone else can enter one with a new partner. A signed declaration is proof of the marriage on its own; without one, each element has to be shown with evidence.
Texas sets no required number of years. A couple can meet all three elements within months, and a couple can share a home for decades without meeting them, for example because there was never an agreement to be married or the couple never presented themselves as spouses. The evidence on each element matters, not the calendar, so a short relationship with strong proof can establish a marriage that a long one cannot.
The simplest proof is a declaration of informal marriage. Under Section 2.402, both spouses sign the declaration on the state’s form at the county clerk’s office, which in San Antonio is the Bexar County Clerk. For declarations signed on or after September 1, 2025, the state’s vital statistics guidance confirms that the form includes a box either spouse can check to keep identifying information other than names confidential, which can matter for privacy and safety.
Without a declaration, the marriage is proved in court with evidence that reaches each element, such as:
A dispute can begin when one partner says there was never a marriage, especially once property or support is at stake. When that happens, the court first decides whether the marriage existed, and the spouse who claims the marriage carries the burden of proving each element.
The agreement element can be the hardest to show, because it is the most private. Cards, messages, or a ring exchanged with words about being married can speak to it, alongside the records that show how the two of you lived. That evidence is worth gathering early, before records are lost or memories fade, with each piece tied to the element it proves.
Timing is where many claims run into trouble. If a proceeding to prove the marriage through evidence is not started before the second anniversary of the date the couple separated and stopped living together, Texas law presumes that the couple never agreed to be married. That presumption is rebuttable, meaning evidence can overcome it, but it shifts the starting point against the spouse claiming the marriage. The separation date is what starts the two years, so pinning down that date early shapes how strong the case will be.
An informal marriage ends the same way a ceremonial marriage does: through a divorce decree, not by moving out. To file in Texas, Section 6.301 requires that one spouse has been a Texas domiciliary for the preceding six months and a resident of the filing county, such as Bexar County, for the preceding 90 days.
Once the marriage is established, the property rules are the same as for any marriage:
The date the marriage began decides what falls in the community estate, so the home, accounts, a business, and debts acquired after that date may all be part of the division.
Our San Antonio team, led by Managing Attorney Diana Davalos, builds the evidence of that start date so your share reflects the life you built.
If you were told you have no rights because there was never a license, you deserve a second look at the facts. Call (210) 942-1951 or contact us today to schedule a free consultation with WSM Law, and find out where common law marriage in Texas leaves you.
