§ 9.31. SELF-DEFENSE. (a) Except as provided in Subsection (b), a person is justified in using force against another when and to the degree he reasonably believes the force is immediately necessary to protect himself against the other’s use or attempted use of unlawful force. (b) The use of force against another is not justified: (1) in response to verbal provocation alone; (2) to resist an arrest or search that the actor knows is being made by a peace officer, or by a person acting in a peace officer’s presence and at his direction, even though the arrest or search is unlawful, unless the resistance is justified under Subsection (c); (3) if the actor consented to the exact force used or attempted by the other; (4) if the actor provoked the other’s use or attempted use of unlawful force, unless: (A) the actor abandons the encounter, or clearly communicates to the other his intent to do so reasonably believing he cannot safely abandon the encounter; and (B) the other nevertheless continues or attempts to use unlawful force against the actor; or (5) if the actor sought an explanation from or discussion with the other person concerning the actor’s differences with the other person while the actor was: (A) carrying a weapon in violation of Section 46.02; or (B) possessing or transporting a weapon in violation of Section 46.05. (c) The use of force to resist an arrest or search is justified: (1) if, before the actor offers any resistance, the peace officer (or person acting at his direction) uses or attempts to use greater force than necessary to make the arrest or search; and (2) when and to the degree the actor reasonably believes the force is immediately necessary to protect himself against the peace officer’s (or other person’s) use or attempted use of greater force than necessary. (d) The use of deadly force is not justified under this subchapter except as provided in Sections 9.32, 9.33, and 9.34.

§ 9.32. DEADLY FORCE IN DEFENSE OF PERSON. (a) A person is justified in using deadly force against another: (1) if he would be justified in using force against the other under Section 9.31; (2) if a reasonable person in the actor’s situation would not have retreated; and (3) when and to the degree he reasonably believes the deadly force is immediately necessary: (A) to protect himself against the other’s use or attempted use of unlawful deadly force; or (B) to prevent the other’s imminent commission of aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery. (b) The requirement imposed by Subsection (a)(2) does not apply to an actor who uses force against a person who is at the time of the use of force committing an offense of unlawful entry in the habitation of the actor.

PC §9.04. THREATS AS JUSTIFIABLE FORCE. The threat of force is justified when the use of force is justified by this chapter. For purposes of this section, a threat to cause death or serious bodily injury by the production of a weapon or otherwise, as long as the actor’s purpose is limited to creating an apprehension that he will use deadly force if
necessary, does not constitute the use of deadly force.

 § 9.42. DEADLY FORCE TO PROTECT PROPERTY. A person is justified in using deadly force against another to protect land or tangible, movable property: (1) if he would be justified in using force against the other under Section 9.41; and (2) when and to the degree he reasonably believes the deadly force is immediately necessary: (A) to prevent the other’s imminent commission of arson, burglary, robbery, aggravated robbery, theft during the nighttime, or criminal mischief during the nighttime; or (B) to prevent the other who is fleeing immediately after committing burglary, robbery, aggravated robbery, or theft during the nighttime from escaping with the property; and (3) he reasonably believes that: (A) the land or property cannot be protected or recovered by any other means; or (B) the use of force other than deadly force to protect or recover the land or property would expose the actor or another to a substantial risk of death or serious bodily injury.

§ 9.43. PROTECTION OF THIRD PERSON’S PROPERTY. A person is justified in using force or deadly force against another to protect land or tangible, movable property of a third person if, under the circumstances as he reasonably believes them to be, the actor would be justified under Section 9.41 or 9.42 in using force or deadly force to protect his own land or property and: (1) the actor reasonably believes the unlawful interference constitutes attempted or consummated theft of or criminal mischief to the tangible, movable property; or (2) the actor reasonably believes that: (A) the third person has requested his protection of the land or property; (B) he has a legal duty to protect the third person’s land or property; or (C) the third person whose land or property he uses force or deadly force to protect is the actor’s spouse, parent, or child, resides with the actor, or is under the actor’s care.
