The Castle Law in Massachusetts

The Castle Law, also recognized as the Castle Doctrine, is a legal principle that permits a person to defend themselves with the use deadly force in certain events within that person’s home, vehicle, or other legally occupied place.

The Castle Law has been around since the mid-1600s in Western Civilization but was not introduced to the US until the 18th century when legal systems began implementing English common laws.

While this law seems straight-forward, there is a lot of fine print, especially in states like Massachusetts. Massachusetts has what is called a “statutory Castle Law” and is much more restrictive compared to other states. A statutory Castle Doctrine means that the law to stand your ground in such situations is limited. In Massachusetts, the Castle Law only applies when you are within the four walls of your home or legally occupied space. So that means if you are on your front lawn, back porch, driveway, etc., the law is not applicable. There also must be strong evidence confirming that one’s life was in danger of great injury or death.

The Massachusetts’s Castle Law states the following, “In the prosecution of a person who is an occupant of a dwelling charged with killing or injuring one who was unlawfully in said dwelling, it shall be a defense that the occupant was in his dwelling at the time of the offense and that he acted in the reasonable belief that the person unlawfully in said dwelling was about to inflict great bodily injury or death upon said occupant or upon another person lawfully in said dwelling, and that said occupant used reasonable means to defend himself or such other person lawfully in said dwelling. There shall be no duty on said occupant to retreat from such person unlawfully in said dwelling.”
