HOW DOES MISSOURI DEFINE SELF-DEFENSE?

If you’ve been charged with a violent crime in Missouri—like assault, manslaughter, or even homicide — one of the most powerful legal tools you might have is the right to self-defense.
But Missouri’s laws aren’t just about “standing your ground” or “defending yourself.” They have specific rules, limits, and conditions.
At KC Defense Counsel, our experienced Kansas City self defense attorneys help clients throughout Kansas City and Missouri understand and assert their self-defense rights. Here’s what you need to know if you’re facing charges and believe your actions were justified.
WHAT IS CONSIDERED SELF-DEFENSE IN MISSOURI?
Missouri law allows individuals to use physical force, including deadly force, when they reasonably believe it’s necessary to protect themselves or others from harm.
According to Missouri Revised Statutes § 563.031, you can use force to defend against:
- Unlawful force
- Imminent harm
- A threat of death, serious injury, or a forcible felony
WHEN CAN YOU USE SELF-DEFENSE?
You may legally use force if:
- You reasonably believe it’s necessary to protect yourself or someone else
- The threat is immediate and unlawful
- You didn’t provoke the other person into attacking
- You are not engaged in criminal activity yourself at the time
WHAT ABOUT DEADLY FORCE?
Missouri law allows the use of deadly force only when You reasonably believe it is necessary to prevent:
- Death
- Serious physical injury
- Or the commission of a forcible felony (like robbery, burglary, rape, or arson)
Deadly force is not allowed to simply stop a non-violent crime, trespassing, or verbal threats.
MISSOURI’S “STAND YOUR GROUND” LAW
Missouri is a Stand Your Ground state. That means:
- You do not have to retreat, even if you could safely walk away.
- You may stand your ground and use force—even deadly force—if you are somewhere you have a legal right to be (your home, your car, a public space, etc.).
This gives you strong protection, but only if all other conditions for self-defense are met.
WHAT IS THE “CASTLE DOCTRINE” IN MISSOURI?
The Castle Doctrine is a specific self-defense rule that applies to:
- Your home
- Your vehicle
- Other property you lawfully occupy
If someone unlawfully enters or attempts to enter your home or vehicle, Missouri law presumes you acted in self-defense, making it harder for prosecutors to challenge your actions.
WHEN SELF-DEFENSE DOES NOT APPLY
You cannot claim self-defense if:
- You were the initial aggressor
- You were engaged in illegal activity at the time (e.g., drug deals, illegal weapons possession)
- The force used was clearly excessive
- The threat was not immediate or real
Even in self-defense claims, the court will evaluate your mindset, your actions, and the level of force used.
