Castle Doctrine in Massachusetts
State-specific overview · Criminal Law
Massachusetts has no Castle Doctrine; you must retreat from your home if safely possible before using force.
How Massachusetts treats Castle Doctrine
Massachusetts does not recognize a Castle Doctrine and instead imposes a duty to retreat even in your own home if you can do so safely. The state follows a traditional common-law approach requiring you to avoid confrontation when escape is reasonably available. Force is permitted only when retreat is impossible or would increase danger. This makes Massachusetts one of the few states with an explicit duty to retreat in your own residence.
The general definition of Castle Doctrine
A law stating that a person's home is their castle and they can use force to defend it without duty to retreat.
The castle doctrine is a legal principle that treats a person's home as a safe place where they have the right to defend themselves and their family with force, including deadly force, without any duty to retreat. The doctrine applies specifically to your own home and sometimes extends to your vehicle or workplace. It's based on the idea that your home is your private sanctuary where you should feel secure. The castle doctrine is narrower than stand your ground laws because it applies only to your own property, not public spaces.
