Self-Defense Laws in Kansas

A person who is not engaged in unlawful activity and who is attacked in a place where the person has a right to be "has no duty to retreat and has the right to stand such person's ground" and use any force that would be justified under Kansas's self-defense statutes.

A person is presumed to have a reasonable belief that deadly force is necessary when the person against whom force is used is unlawfully or forcefully entering, or has unlawfully or forcefully entered and is present within, the dwelling, place of work or occupied vehicle of the person using force, and the person using force knows or has reason to believe this is occurring or has occurred. The presumption does not apply if the other person has a right to be in or lawfully lives there (and is not subject to a protective order); the person being removed is a child, grandchild or in the lawful custody of the other person; the person using force is committing a crime, escaping from a crime or using the place to further a crime; or the other person is a law enforcement officer lawfully entering whom the person knows or reasonably should know is an officer. A person whose use of force is justified "is immune from criminal prosecution and civil action for the use of such force," unless the person against whom force was used is a law enforcement officer who identified themself or whom the person knew or reasonably should have known was an officer.
