Self-Defense in Massachusetts
State-specific overview · Criminal Law
You must retreat to safety if you can do so safely before using force, except in your own home.
How Massachusetts treats Self-Defense
Massachusetts imposes a duty to retreat in public spaces when escape is reasonably available. You have no duty to retreat within your own home or workplace. The state requires that any force used be proportional to the threat and necessary to prevent imminent harm. Courts evaluate self-defense claims based on whether a reasonable person in your position would have believed force was necessary.
The general definition of Self-Defense
The legal right to use reasonable force to protect yourself from harm.
Self-defense is a legal justification for using force against someone who is attacking or about to attack you. The key word is 'reasonable'—the force you use must be proportional to the threat you face. Most states recognize a 'duty to retreat' in some situations, meaning you must try to escape if safely possible before using force. Some states have 'Stand Your Ground' laws that eliminate the duty to retreat and allow you to use force where you have a legal right to be.
