How to Prove a Common-Law Marriage in Texas

By Tom Streissguth

The laws of the individual states govern common law marriages; Texas is one of several states that affords legal recognition to these relationships, which it officially calls "informal marriages." There is an established procedure in Texas to register an informal marriage or prove that a marital relationship exists between a man and a woman that is without the benefit of a religious or civil ceremony.


You may establish a legal informal marriage in Texas by registering the marriage with the local county court. For this, state law requires a "Declaration and Registration of Informal Marriage," which lists the names of both parties to the marriage, declares that neither party is related to one another by blood or adoption, and affirms the parties agreed to be married to one another as of a certain date, lived together and held themselves out to the public as husband and wife. The parties must sign the declaration and take an oath before the clerk of court.

Unregistered Common Law Marriages

If a Texas informal marriage is not registered, the couple may still have it legally recognized. The couple must meet three basic requirements: both parties must agree to the marriage, live together in the state as husband and wife, and hold themselves out to the public as a married couple. The representation of an informal marriage to others can be proven by witnessed statements, signed contracts or lease agreements, or by filing a joint tax return.

If a couple in an informal marriage decides to separate and later file for divorce, either spouse must prove the validity of the informal marriage within two years of the separation. If the couple does not meet this deadline, state law presumes the informal marriage never existed. As a result, a legal divorce, and the protection of property and rights that divorce laws afford former spouses, becomes unavailable to the couple unless they can overcome this presumption. This provision of Texas law applies to couples that separated after September 1, 1989.

Divorce Law and Informal Marriage

To prove an informal marriage, the party asserting the marriage must provide evidence of all three requirements as set down in the law. If a couple successfully asserts an informal marriage, the state allows a legal divorce. Division of property, child custody and other matters are decided by law in the same manner as they would be with a formally married couple. Even if a couple has not proven a valid informal marriage, either partner may petition the court for orders concerning child support and visitation.

Connecticut Divorce Law and Domestic Partners

Domestic partnerships, known as civil unions in Connecticut, no longer exist as such in the state. In 2009, the Connecticut legislature passed a law treating same-sex couples who entered into civil unions before October 1, 2010 as married as of that date. Since that time, same-sex couples may obtain divorces in Connecticut under the same rules that govern heterosexual divorces.

New York Domestic Partner Divorce Laws

New York laws are relatively clear about the standards and procedures for marriage and divorce, including issues of child custody, property division and spousal support. However, same-sex divorce issues and domestic partnership dissolutions are not always so clear, because this is a relatively new area of law. New York couples can choose to marry or form a domestic partnership, and the dissolution procedures for each are very different.

How to Be Eligible for an Annulment

While a divorce terminates a legal marriage, an annulment means that the marriage never existed legally. To qualify for an annulment, a marriage must be legally void or voidable. Void means that it is not valid, while voidable means that a court can declare it to be invalid if it is challenged. To be eligible for an annulment you must be able to prove one of the specific grounds to establish that your marriage is void or voidable. Otherwise, eligibility for an annulment is simple. However, many states require strict proof to declare an annulment.
