Grounds for Divorce in Texas: No-Fault vs. Fault, and When It Matters

Texas gives you seven legal grounds for divorce, but for almost everyone asking this question, the practical answer comes down to one word: insupportability. It's the no-fault ground used in the overwhelming majority of Texas divorces — including every standard DIY case — because it requires no proof of wrongdoing and keeps the case administrative rather than adversarial. The other six grounds still matter, though, mostly because of what fault can do to the property split. Here's the full list and when each one is actually worth pleading.

The No-Fault Grounds

Insupportability (§ 6.001). The marriage has become insupportable because of discord or conflict of personalities that destroys the legitimate ends of the marriage, with no reasonable expectation of reconciliation. That's the entire standard. No evidence of misconduct, no waiting period of separation, no need for your spouse to agree it's true. If you tell the judge under oath that the marriage is insupportable, the ground is established. This is what "no-fault divorce" means in Texas — and it's the ground in the Supreme Court-approved form petitions.

Living apart (§ 6.006). The spouses have lived apart without cohabitation for at least three years. Technically no-fault, practically rare — why wait three years when insupportability works on day one?

Confinement in a mental hospital (§ 6.007). A spouse has been confined for at least three years with a prognosis that recovery is unlikely or relapse probable. Narrow by design.

The Fault Grounds

Four traditional fault grounds remain on the books:

• Cruelty (§ 6.002) — cruel treatment of a nature that makes further living together insupportable
• Adultery (§ 6.003) — exactly what it says, proven by clear and convincing evidence
• Felony conviction (§ 6.004) — conviction of a felony with at least a year in prison and no pardon
• Abandonment (§ 6.005) — voluntary abandonment for a continuous year with intent to abandon

Why Anyone Pleads Fault: The Murff Factor

Here's the part that surprises people: fault grounds in Texas are less about getting the divorce and more about the money. Texas divides community property in a manner the court deems "just and right" — not automatically 50/50. Since the Texas Supreme Court's decision in Murff v. Murff (615 S.W.2d 696, 1981), fault in the breakup of the marriage is an explicit factor justifying a disproportionate division of the community estate in favor of the innocent spouse.

In practice: proven adultery or cruelty can push the split to 55/45, 60/40, or beyond. Fault can also matter indirectly in conservatorship decisions and in claims of fraud on the community (spending marital funds on an affair partner, for example, which courts can reimburse).

Why Pro Se Filers Should Almost Never Plead Fault

The strategic upside comes with a process cost that kills DIY cases:

• Proof requirements. Insupportability needs your sworn statement. Adultery needs evidence — messages, records, testimony — that meets an evidentiary standard.
• Litigation machinery. Fault allegations invite discovery, depositions, subpoenas, and forensic asset tracing. The case stops being a form-filling exercise the moment fault is pleaded.
• Retaliation. A spouse served with an adultery petition who was prepared to sign a waiver now hires an attorney instead. Your $500 agreed divorce becomes a $7,000–$20,000 contested one.

The standard practice — even among attorneys — is to plead insupportability and negotiate the property division on its merits. Fault enters the conversation as leverage in mediation, not as a pleaded ground. If you genuinely have a fault case worth proving, that's precisely the signal that you need counsel, not a form packet.

One more nuance: you don't need your spouse's agreement on grounds. Texas grants divorces on insupportability even over one spouse's objection — a spouse who refuses to participate can't veto the divorce, only slow it down through the default process.

Common Questions

Is Texas a no-fault divorce state? Yes — insupportability is a true no-fault ground requiring no proof of misconduct and no separation period. Texas simply also retains fault grounds, which most filers ignore.

Does adultery affect property division in Texas? It can. Under Murff v. Murff, fault is one of the factors courts weigh for a "just and right" division, and proven adultery can justify awarding the innocent spouse a larger share. But proving it means litigating it.

Do both spouses have to agree on the grounds? No. One spouse's sworn testimony that the marriage is insupportable is enough. The other spouse can contest custody or property terms, but can't block the divorce itself.

If you're mapping out an uncontested filing, the Texas Divorce Filing Process Guide covers the insupportability-based track end to end — petition, waiver, decree language, and prove-up — which is the path 95% of DIY filers should be on.
