Pleading Self-Defense in a Texas Domestic Violence Case
In a Bexar County Assault & Domestic Violence case, the person who called 911 isn’t always the one who was actually being attacked, and the person arrested isn’t always the aggressor. If you were defending yourself, or someone else in your household, understanding exactly how Texas self-defense law applies to a domestic setting — and what evidence actually proves it — is essential to your case. This is the job of your San Antonio criminal defense attorney.
The Legal Foundation: Texas Penal Code Sections 9.31 and 9.32
Under Texas Penal Code Section 9.31, a person is justified in using force against another when, and to the degree, they reasonably believe the force is immediately necessary to protect against the other person’s use or attempted use of unlawful force. Two elements matter most: the belief has to be reasonable, and the threat has to be immediate — not a past threat, and not a speculative future one.
Deadly force requires more. Under Section 9.32, deadly force is justified only if you’d already be justified in using ordinary force under Section 9.31, and you reasonably believe deadly force specifically is immediately necessary to protect against the other person’s use or attempted use of unlawful deadly force, or to prevent them from imminently committing certain serious violent crimes. Texas does not require you to retreat before using force in self-defense, in your own home or elsewhere.
Losing — and Regaining — the Right to Self-Defense
Texas law limits self-defense for someone who provoked the confrontation in the first place. If you started the altercation, you generally can’t then claim you were defending yourself from the response you provoked.
But this isn’t necessarily permanent. Under Section 9.31(c), if you clearly abandon the encounter, or clearly communicate your intent to abandon it, and the other person continues using unlawful force against you anyway, your right to claim self-defense can be restored. This matters considerably in domestic situations, where an argument can escalate, one person can try to walk away or de-escalate, and the other can continue regardless — a sequence that can shift who actually has a viable self-defense claim partway through the same incident.
“Mutual Combat”: What It Actually Means Under Texas Law
You may hear the term “mutual combat” used to describe a situation where both people were fighting. It’s worth understanding precisely what this means under Texas law, because it’s not a standalone legal defense with its own statute — Texas has no law titled “mutual combat.” Instead, it’s a concept that operates through two existing legal doctrines: the provocation and aggressor rules already discussed under Section 9.31(b), and Section 22.06, which allows consent as a limited defense to assault in circumstances that don’t involve serious bodily injury or a deadly weapon.
Texas courts have described mutual combat as requiring a prior agreement — which can be spoken or implied through conduct — where both people voluntarily choose to engage in a physical confrontation. If the state can show that kind of mutual agreement, a self-defense claim becomes considerably harder to sustain, because the law generally doesn’t allow someone to voluntarily enter a fight and then claim they had no choice but to defend themselves.
It’s worth being honest about something here: mutual combat and self-defense arguments are generally harder to sustain specifically in family violence cases, where courts and prosecutors tend to scrutinize the dynamic more closely and are, understandably, protective of anyone who may genuinely be a victim. This doesn’t mean the argument isn’t available — it means it has to be built carefully, on real evidence, rather than assumed.
Both People Can Be Charged
If officers arrive at a scene and can’t clearly identify a single aggressor, Texas law allows both participants to be charged. Being charged is not the same as the case against you being strong — the state still has to prove its case against you specifically, beyond a reasonable doubt, regardless of what happens with any charge against the other person.
What Actually Proves Self-Defense
A self-defense claim in a domestic case is won or lost on evidence, and the most important evidence often has a short shelf life.
Your Own Injuries
Defensive wounds — scratches, bite marks, bruising on your forearms consistent with blocking or fending off contact — can directly support your account, especially when they’re documented immediately. These marks fade within days, so photographing them right away, and seeking medical attention where appropriate so there’s an official record, matters considerably. If law enforcement documented injuries on both people at the scene, that itself can support the argument that you weren’t the only one using force.
The 911 Call
The recording of the 911 call — including tone, background sounds, and what’s actually said — often becomes significant evidence. It’s a genuine misconception that whoever called 911 first is automatically treated as the victim; investigators and prosecutors look at the whole picture, not just who dialed the phone.
Other Evidence Worth Preserving
Body-worn camera footage from responding officers, witness statements from anyone who saw or heard the incident, and any pattern of prior threatening or controlling behavior can all matter. One Texas-specific fact worth knowing: Texas is a one-party consent state, meaning you can legally record a conversation you’re personally a part of without the other person’s knowledge. This can be relevant if there’s an ongoing pattern of threats or conduct worth documenting — though safety always comes first, and this should never be pursued in a way that puts you at greater risk in the moment.
What This Means for Your Bexar County Case
If you were defending yourself or someone else, the evidence that proves it is often at its strongest in the first hours and days after the incident, and it fades quickly. Photographing your own injuries, preserving any relevant communications, and getting your account to a criminal defense attorney as early as possible gives your self-defense claim the best chance of being built on real, contemporaneous evidence rather than reconstructed months later from memory alone.
Frequently Asked Questions
Q: Can I claim self-defense if I was the one who called 911?
A: Yes. Calling 911 doesn’t determine who was actually defending themselves — investigators and prosecutors look at the full evidence, not just who made the call.
Q: What if I hit back first?
A: Self-defense isn’t about who struck first physically — it’s about whether you reasonably believed force was immediately necessary to protect yourself, and whether your response was proportionate. If you were being attacked and responded to protect yourself, that can still be self-defense even if your specific physical response came second in sequence.
Q: Is “mutual combat” a real legal defense in Texas?
A: Not as a standalone statute — Texas has no law called “mutual combat.” It’s a concept that operates through the state’s provocation and self-defense laws, and it generally requires showing both people agreed, in some way, to fight.
Q: We were both arrested. Does that mean neither of us has a good case?
A: No. Both people being charged doesn’t mean the evidence against each person is equally strong. Your case is evaluated on its own facts and evidence, independent of what happens with any charge against the other person.
Q: What should I do right now if I have injuries from defending myself?
A: Photograph them as soon as possible, since they can fade within days, and seek medical attention where appropriate to create an official record. Then talk to an attorney promptly, since early evidence is often the strongest evidence in a self-defense case.
