Common Law Marriage Survivor Benefits in Texas: How to Prove It After Death

Texas is one of the few states that still fully recognizes common law marriage — called "informal marriage" under Texas law. If you and your partner lived as a married couple in Texas without a formal ceremony or marriage license, you may have the same inheritance rights, survivor benefits, and property rights as any formally married spouse.

The problem is that after a death, you have to prove the marriage existed. And when the state agency, bank, or insurance company asks for a marriage certificate, "we were together for 20 years" isn't documentation.

Here's what Texas requires — and how to build the case.

What Makes a Common Law Marriage Valid in Texas

Under Texas Family Code Section 2.401, an informal (common law) marriage exists when all three elements are present simultaneously:

1. Agreement to be married — you and your partner agreed to be husband and wife (or spouse and spouse)
2. Living together in Texas as husband and wife
3. Representing to others that you were married — telling friends, family, coworkers, or the public that you were married

All three elements must have been present at the same time. A long-term relationship without the held-out-as-married element won't qualify. A couple who held themselves out as married but lived in separate states for years creates complications.

The Two-Year Rebuttable Presumption

This is the rule that creates the most urgency for surviving partners.

Under Texas Family Code Section 2.401(b), if two years have passed since the parties separated without filing a proceeding to establish the informal marriage, a rebuttable presumption arises that no informal marriage existed.

For surviving partners, this rule applies if you had been separated from your partner prior to their death. If you lived together continuously until death, the two-year clock is not a concern.

But if there was a separation — even a temporary one — and it lasted more than two years before the death, you may face a legal presumption that no marriage existed. That presumption can be rebutted with strong evidence, but it puts the burden squarely on you.

How to Prove an Informal Marriage After the Partner Dies

Since the partner who could confirm the agreement to marry is now dead, proving common law marriage requires objective documentary evidence. The more of the following you can provide, the stronger your case:

Direct evidence of the marriage agreement:

• A Declaration of Informal Marriage filed with the county clerk (the most definitive evidence — if you filed one while both of you were alive, the case is straightforward)
• Written communications (letters, emails, texts) where either party referred to the other as their spouse or discussed being married

Evidence of cohabitation:

• Joint lease agreements or mortgage documents
• Joint utility accounts or bank accounts
• Shared address on both parties' driver's licenses or IDs
• Joint tax returns filed as "Married Filing Jointly" or "Married Filing Separately" — this is particularly powerful evidence

Evidence of holding out as married:

• Life insurance policies naming you as "spouse"
• Retirement account beneficiary designations identifying you as spouse
• Health insurance enrollment listing you as "spouse"
• Social media, holiday cards, or family photographs identifying you as husband/wife/spouse
• Written statements from friends, family members, employers, or coworkers who knew you as a married couple

Social Security Survivor Benefits and Common Law Marriage

The Social Security Administration (SSA) does recognize common law marriages for survivor benefit purposes — but you have to prove it to them.

The SSA follows the law of the state where the couple last lived as husband and wife. Since Texas recognizes informal marriage, the SSA will accept it — if you prove it.

To establish an informal marriage for Social Security purposes, you typically need to submit:

• Form SSA-754 (Statement of Marital Relationship) — a sworn declaration describing when and how the informal marriage began
• Form SSA-753 (Statement Regarding Marriage) — completed by a blood relative of the deceased who can attest to the marriage

Both forms require details: when did you start living together, when did you begin representing yourselves as married, and what evidence supports that. The SSA will make its own determination based on your sworn statements and supporting documentation.

Probate Court and Inheritance Rights

If your partner died without a will, Texas intestate succession law gives the surviving spouse specific inheritance rights — but only if you're legally recognized as the spouse.

For an informal marriage, you can file a proceeding in the county probate court to establish the marriage under the Texas Family Code. This typically involves submitting evidence similar to what's described above and requesting a court finding that an informal marriage existed.

If your partner died with a will that names you as a beneficiary (and you're identified as "my spouse" or by name), you generally don't need to prove the marriage separately for the will to operate — you're a named beneficiary. But if the will is contested by other heirs who dispute the marriage, you'll need to prove it in court.

Property Rights in an Informal Marriage

If the informal marriage is valid, you have the same community property rights as a formally married spouse. Property acquired during the marriage is presumed community property, meaning your deceased partner's half of community property assets is subject to their estate, and your half is already yours.

But community property rules require you to first establish that the marriage existed and when it began. The date the informal marriage started determines what property is community and what is separate.

TRS, ERS, and Pension Benefits

The Teacher Retirement System (TRS) and Employees Retirement System (ERS) pay death benefits to the designated beneficiary on file — which may or may not be you. If your partner designated you as their beneficiary but identified you as "spouse," and the agency questions whether you are the legal spouse, you'll need documentation of the informal marriage.

If your partner named someone else as beneficiary (or named no one), the default statutory order kicks in, starting with the surviving spouse. To claim as the surviving spouse of an informal marriage, you would need to provide the same documentary evidence to TRS or ERS.

Contact TRS at (800) 223-8778 or ERS at (877) 275-4377 to ask about their specific procedures for informal marriage claims.

Start Gathering Evidence Now

If you believe you qualify as an informal surviving spouse and need to establish the marriage:

1. Pull every joint document you can find — tax returns, bank statements, insurance policies, lease agreements
2. Gather written statements from family members and friends who knew you as a married couple
3. Look for any prior written references to marriage in your own communications
4. Check whether a Declaration of Informal Marriage was ever filed with the county clerk where you lived

Acting quickly matters. Witnesses' memories fade, documents get harder to locate, and some agency deadlines for survivor benefit claims are as short as one year from the date of death.

The Full Range of Benefits You May Be Entitled To

Proving an informal marriage unlocks the same survivor benefits as a formal marriage: Social Security survivor benefits, TRS/ERS death benefits, COBRA health insurance continuation, Texas homestead property rights, and inheritance under intestate succession. Each benefit requires a separate application — and some have deadlines as short as 60 days (COBRA) or one year (workers' comp).
