" (1) (a) A person is justified in threatening or using force against another when and to the extent that the person reasonably believes that force or a threat of force is necessary to defend the person or a third person against another person's imminent use of unlawful force. (b) A person is justified in using force intended or likely to cause death or serious bodily injury only if the person reasonably believes that force is necessary to prevent death or serious bodily injury to the person or a third person as a result of another person's imminent use of unlawful force, or to prevent the commission of a forcible felony. (2) (a) A person is not justified in using force under the circumstances specified in Subsection (1) if the person: (i) initially provokes the use of force against the person with the intent to use force as an excuse to inflict bodily harm upon the assailant; (ii) is attempting to commit, committing, or fleeing after the commission or attempted commission of a felony; or (iii) was the aggressor or was engaged in a combat by agreement, unless the person withdraws from the encounter and effectively communicates to the other person his intent to do so and, notwithstanding, the other person continues or threatens to continue the use of unlawful force."
Stand Your Ground Laws are often expansions of the Castle Laws. They address the use of force outside of one's home, place of work, or vehicle. They cover most of the same issues as the castle laws (the places where this law applies, the requirements fro use of deadly force, if there is a duty to retreat, the amount of force that maybe used in defending one's self or others) the main difference is the location. Some states that do not have a technical Stand Your Ground Law have extensive Castle Laws that address locations outside of the home, place of work, etc. The circumstances of the law vary widely from state to state.
