Castle Doctrine is similar to “stand your ground,” but is typically limited to real property, including a person’s home, property and, in some states, cars or workplaces. The concept is that an individual has a right to be safe and secure within his or her own home or “castle” and should not have to retreat from his or her home in order to be safe. Depending on the state, an individual may have the right to protect himself or herself, other people, and his or her property by force — in some instances even employing deadly force against intruders without retreating.
Because I, and a lot of my friends and associates, live on the Missouri / Kansas border, I have included both States in this information post. This is NOT Legan Advise. You are advised to speak with an attorney or law enforcement regarding your current rights. This is just information available on the Internet.

Missouri
Missouri’s Castle Doctrine, codified under Section 563.031 of the Missouri Revised Statutes, gives residents the legal right to use physical or deadly force to defend themselves against intruders in their home, vehicle, or private property, without a duty to retreat.
Key Legal Protections
- No Duty to Retreat: You do not have to back down or attempt to escape an intruder before acting in self-defense. This applies as long as you are in a place you have a legal right to be (your home, vehicle, or private property you own or lease) and you are not engaged in an unlawful activity.
- Presumption of Fear: The law presumes that an individual has a reasonable fear of death or serious physical injury if someone unlawfully and forcibly enters (or attempts to enter) their dwelling, residence, or vehicle.
- Use of Deadly Force: You are legally justified in using deadly force if you reasonably believe it is necessary to protect yourself or someone else from death, serious physical injury, or to prevent a forcible felony (such as burglary, kidnapping, or robbery).
Important Limitations
- Proportionality: Force must be reasonable and proportional to the threat. Deadly force cannot be used to protect mere property without a credible, immediate threat to human life.
- Unlawful Occupancy: The protections of the Castle Doctrine do not apply if you are unlawfully present or remaining in the dwelling or vehicle in question.
- Initial Aggressors: You generally cannot claim self-defense if you are the one who instigated the violent confrontation or altercation.
Stand Your Ground – Missouri
Missouri’s “Stand Your Ground” law (RSMo Section 563.031) removes the duty to retreat before using force in self-defense. Individuals have no obligation to try to walk away or retreat if they are lawfully present in a location and reasonably believe physical or deadly force is necessary to protect against death, serious injury, or a forcible felony.
Key Principles of the Law:
- No Duty to Retreat: You can legally “stand your ground” and use reasonable force in any public or private location you have the legal right to be (including homes, vehicles, and private property).
- Reasonable Belief: The threat of death or severe bodily harm must be imminent, and the force used must be both reasonable and proportional to the threat.
- Initial Aggressor: The protections of the law generally do not apply to someone who acts as the “initial aggressor” in a confrontation.
- Affirmative Defense: In Missouri, “Stand Your Ground” is an affirmative defense. This means the defense acknowledges the force was used but presents evidence that it was justified to prevent harm.
For detailed interpretations and complete statutes, consult the full Missouri Revised Statutes Section 563.031 or the Giffords Law Center summary. If you are facing specific legal circumstances, speaking with a licensed Missouri criminal defense attorney is recommended.
Kansas
Kansas law (Statutes Kan. Stat. Ann. § 21-5223) features a robust Castle Doctrine that legally presumes an individual’s right to defend themselves, permitting the use of deadly force without any obligation to retreat if they are in their dwelling, place of work, or occupied vehicle.
Key Legal Protections
- No Duty to Retreat: Residents are legally justified to “stand their ground” and use reasonable—including deadly—force without attempting to flee or de-escalate the situation.
- The Presumption of Danger: Under the law, if an intruder is in the process of unlawfully and forcefully entering (or attempting to remove you from) a dwelling, workplace, or occupied vehicle, it is legally presumed that you have a reasonable fear of imminent death or great bodily harm.
- Civil Immunity: Individuals who use legally justified force or deadly force in these scenarios are immune from being sued in civil court by the attacker or their estate.
Important Limitations
- Unlawful Occupancy: The Castle Doctrine does not apply if the person you are using force against has a lawful right to be in the location (e.g., a co-owner, lawful tenant, or guest).
- Initial Aggressor: You generally cannot claim this legal defense if you provoked or were the initial aggressor in the altercation.
- Protection of Property: Deadly force is almost never justified solely to protect personal property or belongings, as the law prioritizes the protection of human life.
For a full understanding of the state’s statutes regarding use of force, you can review Kansas Statutes Annotated Chapter 21, Article 52.
Stand Your Ground – Kansas
Kansas is a “Stand Your Ground” state, meaning you have no legal duty to retreat from a threat before using force if you are in a place where you have a legal right to be. This applies statewide, in public or private spaces, and includes the Castle Doctrine for your home, vehicle, and workplace.
Core Legal Principles
- No Duty to Retreat: Under Kan. Stat. Ann. §§ 21-5222 and 21-5230, if you are not engaged in unlawful activity and are attacked where you have a lawful right to be, you can “stand your ground” and use force.
- Reasonable Belief: You are only justified in using force—up to and including deadly force—if you reasonably believe it is necessary to prevent imminent death or great bodily harm to yourself or others.
- The Castle Doctrine: You are also legally justified to use deadly force to prevent an unlawful, forceful entry into your dwelling, place of work, or occupied vehicle.
Immunity and Burden of Proof
Kansas provides robust protections for individuals who act in self-defense, including the following provisions:
- Pretrial Immunity Hearing: If you invoke a self-defense claim, you are entitled to a pretrial hearing where a judge evaluates if your use of force was reasonable.
- Burden Shift to the Prosecution: During this hearing, the burden of proving that your use of force was not justified falls on the prosecution, rather than on the defendant.
- Immunity from Prosecution: If the judge determines your actions were legally justified and reasonably necessary, the case can be dismissed, and you are granted absolute immunity from both criminal prosecution and civil suits.
