Criminal Offenses - As introduced, specifies that a person using force intended or likely to cause death or serious bodily injury from within the person's residence or dwelling is presumed to have acted in self-defense when that force is used against an individual armed with a deadly weapon who is unlawfully present on the person's property and outside of the enclosed structure of the person's residence or dwelling. - Amends TCA Title 39, Chapter 11 and Title 40.

HB 931 amends Tennessee law to create a legal presumption that a homeowner acted in self-defense when using force likely to cause death or serious injury against an armed intruder. This presumption applies specifically when the intruder is unlawfully on the property (but outside the main home structure) and armed with a deadly weapon. The bill directly affects homeowners who use force against such intruders, shifting the burden to prosecutors to disprove self-defense in these scenarios. It does not change general self-defense rules but adds this specific presumption for armed intruders on property outside the home's enclosed structure.
