Many couples ask whether they can register a common law marriage to make it legally official. The answer depends on where you live. Most states that recognize common law marriage do not require or even allow registration, while a few states have special procedures.
For example, Texas allows couples to file a Declaration of Informal Marriage, and Utah requires a court or authorized administrative body to recognize a common law marriage before it becomes legally valid. In most other states, there is no registration process because the marriage is established by meeting the state’s legal requirements.
This guide explains how to register a common law marriage, where registration is available, and what to do if your state does not offer it.

Can You Register a Common Law Marriage?
Sometimes.
Unlike a traditional marriage, common law marriages generally do not involve obtaining a marriage license or filing a marriage certificate.
Whether you can register a common law marriage depends entirely on state law.
There are three general approaches:
- States with a registration option, such as Texas.
- States requiring court recognition, such as Utah.
- States with no registration process, where the marriage is determined by legal evidence if questioned.

How to Register a Common Law Marriage in Texas
Texas is unique because it allows eligible couples to file a Declaration of Informal Marriage.
The general process includes:
- Confirm that both partners meet Texas’s legal requirements.
- Visit the appropriate county clerk’s office.
- Complete the Declaration of Informal Marriage.
- Provide any required identification.
- Pay the applicable filing fee.
- Receive an official record of the declaration.
Although filing is optional, it provides strong evidence that a valid marriage exists.
How Does Utah’s Process Work?
Utah does not have a registration system.
Instead, couples must ask a court (or another authorized decision-maker under state law) to recognize their relationship as a valid marriage not solemnized.
The court reviews evidence showing that the legal requirements were met before granting recognition.
What Happens in States Without Registration?
Most states that recognize common law marriage do not allow couples to register the marriage.
Instead, if the relationship is later questioned—for example, during a divorce, inheritance dispute, or benefits claim—a court examines the available evidence.
Evidence may include:
- Joint tax returns
- Joint bank accounts
- Property ownership documents
- Insurance policies
- Beneficiary designations
- Testimony from friends and family
- Documents showing the couple publicly identified as spouses
Why Would Someone Want to Register a Common Law Marriage?
Where registration is available, it may help:
- Provide official proof of the marriage
- Simplify inheritance claims
- Support insurance or employment benefit applications
- Help with Social Security or retirement benefit claims
- Reduce disputes during divorce
However, in most states, registration simply is not an option.
Do You Need a Marriage License?
Usually, no.
A common law marriage generally does not require a marriage license.
However, if a couple chooses to have a traditional ceremony instead, they must follow the normal marriage licensing process required by their state.
Can You Register a Common Law Marriage After Many Years?
Only if your state’s law allows it.
For example:
- Texas may allow eligible couples to file a Declaration of Informal Marriage even after they have lived together for years, provided they meet the legal requirements.
- States without a registration process do not allow couples to simply register years later.

While Texas allows couples to file a Declaration of Informal Marriage, most states that recognize common law marriage do not provide any registration process. Instead, the existence of the marriage is determined by whether the couple met the state’s legal requirements and can prove their relationship if it is ever challenged.
