Homicide and Self-Defense in Texas: Who Has to Prove What

The short answer. Self-defense in Texas is a justification, not an excuse, and the burden is not what most people assume. Once the accused produces some evidence raising self-defense, the State must disprove it beyond a reasonable doubt. Penal Code § 2.03(d); Saxton v. State, 804 S.W.2d 910 (Tex. Crim. App. 1991). A person lawfully present who did not provoke the encounter and was not engaged in criminal activity has no duty to retreat, and the jury may not be told to consider whether he could have. Penal Code § 9.32(c), (d).

A man has half a second to decide. A grand jury has six months to think about it, in a room with good lighting, with the body on a diagram and nobody’s heart going.

That asymmetry is the whole problem in a self-defense homicide case, and the law knows it. That is why the statute asks what the accused reasonably believed in the moment, not what a reasonable person concluded afterward with all the time in the world.

What homicide charges exist in Texas?

Texas homicide offenses

Offense	Statute	Punishment range
Capital murder	§ 19.03	Life without parole, or death where the State seeks it
Murder	§ 19.02	First degree felony, 5 to 99 years or life
Murder, with sudden passion found at punishment	§ 19.02(d)	Second degree felony, 2 to 20 years. The accused raises it at the punishment stage and must prove it by a preponderance
Manslaughter, recklessly causing death	§ 19.04	Second degree felony, 2 to 20 years
Criminally negligent homicide	§ 19.05	State jail felony, 180 days to 2 years

Two things in that table do most of the work in real cases. The mental state, which is the difference between murder and manslaughter and negligent homicide. And sudden passion, which is a punishment issue rather than a guilt issue and which many people never hear about until it is too late to develop the evidence for it.

When does Texas law justify force?

Ordinary force is justified under § 9.31 when and to the degree the actor reasonably believes it is immediately necessary to protect himself against another’s use or attempted use of unlawful force.

Deadly force is narrower. Under § 9.32(a) it is justified when the actor would be justified under § 9.31 and he reasonably believes deadly force is immediately necessary either to protect against the other’s use or attempted use of unlawful deadly force, or to prevent the other’s imminent commission of aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery.

Deadly force is defined at § 9.01(3) as force intended or known to cause, or in the manner of its use capable of causing, death or serious bodily injury. Defense of a third person is covered by § 9.33, measured by the circumstances as the actor reasonably believed them to be.

The presumption most people call the castle doctrine

Section 9.32(b) presumes the actor’s belief was reasonable, but only if all three of the following are true.

He knew or had reason to believe the other person unlawfully and with force entered or was attempting to enter his occupied habitation, vehicle, or place of business or employment; or was unlawfully and forcibly removing or attempting to remove him from one of those places; or was committing or attempting one of the listed violent felonies.
He did not provoke the person against whom the force was used.
He was not otherwise engaged in criminal activity, other than a Class C traffic offense, at the time.

That third condition is where the presumption most often disappears. A man defending himself in his own driveway who happens to have a small amount of a controlled substance in his pocket can lose the presumption entirely. He still has self-defense. He no longer has the shortcut.

Is there a duty to retreat in Texas?

No, within limits that matter. Under § 9.32(c), a person who has a right to be where he is, who did not provoke the other person, and who is not engaged in criminal activity is not required to retreat before using deadly force. And § 9.32(d) goes further: in deciding whether his belief was reasonable, the finder of fact may not consider whether he failed to retreat.

That is a rule about what a prosecutor may argue to a jury, and it has to be enforced in the moment, with an objection and a ruling, or it is not enforced at all.

What defeats self-defense

Section 9.31(b) lists circumstances where force is not justified at all. Response to verbal provocation alone. Resisting an arrest or search the actor knows is being made by a peace officer, even an unlawful one, unless the officer used greater force than necessary first. Consenting to the exact force used. Provoking the other’s use of force, unless the actor abandoned the encounter or clearly communicated his intent to and the other person kept coming.

And one that sends people to prison who never saw it coming: § 9.31(b)(5) removes the justification where the actor sought an explanation from or a discussion with the other person about their differences while carrying a weapon in violation of § 46.02 or possessing or transporting one in violation of § 46.05. Going to talk to a man, unlawfully armed, forfeits the defense. I have seen that paragraph decide a case.

Who has to prove it?

This is the part I want every juror in Bexar County to understand, because it is counterintuitive and the State rarely volunteers it.

Self-defense is a defense under Penal Code § 2.03. The accused carries a burden of production only: he must bring forward some evidence raising the issue. Once he does, the burden of persuasion is on the State, and the State must disprove the defense beyond a reasonable doubt. Saxton v. State, 804 S.W.2d 910 (Tex. Crim. App. 1991); Zuliani v. State, 97 S.W.3d 589 (Tex. Crim. App. 2003).

The accused does not have to prove he acted in self-defense. He does not have to testify. If the jury has a reasonable doubt about whether the killing was justified, the verdict is not guilty. Getting that stated correctly in the court’s charge, and stated plainly in argument, is as important as any witness in the case.

The dead man’s history is not off limits

Article 38.36(a) of the Code of Criminal Procedure permits either side in a homicide prosecution to offer evidence of all relevant facts and circumstances surrounding the killing, the previous relationship between the accused and the deceased, and the condition of the accused’s mind at the time.

In a self-defense case that opens the door to what my client knew about the other man. Prior threats. Prior violence he had seen or been told about. What was said in the weeks before. The State will tell a jury that the man on the ground is the victim. Article 38.36 is how a jury hears the rest of the relationship instead of the last ten seconds of it.

Bail in a homicide case is different now

Murder and capital murder are both on the list in Article I, Section 11d of the Texas Constitution, added November 4, 2025. In those cases a judge must deny bail before trial if the State makes one of two showings at a hearing. Read what Section 11d changed , because that hearing happens in the first days and it decides where your family spends the next year.

The first hours

Say that you were in fear for your life, say that you want a lawyer, and then stop talking. Not because you have something to hide. Because adrenaline makes people say the wrong words about the right facts, and the wrong words are what gets read to the jury eighteen months later.

Then someone should be preserving, that day: the scene photographs, the clothing, the neighbors’ doorbell cameras before they overwrite, the 911 audio, and every witness who was standing there and is about to disappear.
