There is the old saying that a man’s home is his castle — albeit smaller and certainly with better creature comforts like indoor plumbing, central heat, and likely air conditioning. Castles were defended by a lord’s personal troops, where an individual must defend the home and protect his or her family.

The “Castle Doctrine” governs when a person may lawfully use force, including deadly force, to defend themselves within their home or other protected spaces.

The Castle Doctrine originated in early 17th-century English common law, establishing that an individual has no duty to retreat when attacked in their own home, treating the home as a “castle.”

This concept was famously articulated by Sir Edward Coke in 1604 as “the house of everyone is to him as his castle and fortress.” It legally justifies the use of reasonable, sometimes deadly, force against intruders. It might seem odd that this originated in England, even as it remains a foundation of American self-defense law.

The doctrine was adopted into American law following independence and has been deeply embedded in the American understanding of self-defense, property rights, and individual protection. In the 19th century, U.S. courts, notably in Ohio in 1876, reinforced this by holding that a “true man” is not obliged to flee an assailant, thereby expanding the idea of defending one’s home and honor.

According to criminal defense attorney Emma K. Wittmann of Attorneys For Freedom Law Firm and “Attorneys On Retainer” (AOR), the Castle Doctrine may seem straightforward in principle. Yet, its application varies dramatically across jurisdictions and often raises nuanced questions of reasonableness, necessity, and proportionality.

Castle Doctrine: No Need to Flee the Home

As established, those in their home don’t need to attempt to flee or engage in a “duty to retreat,” as they might while outside the home.

“The Castle Doctrine establishes that individuals have no duty to retreat when defending themselves in their own home, based on the principle that ‘a person’s home is his castle.’ At its core, the Castle Doctrine provides that a person who is lawfully present in their dwelling has no duty to retreat before using reasonable — even deadly — force against an intruder who unlawfully enters or attempts to enter,” explained Wittmann.

“In contrast, the traditional duty to retreat requires individuals to avoid using deadly force if they can safely retreat and escape the threat. The castle doctrine serves to remove this requirement within one’s ‘castle’ or home,” Wittmann added.

Reasonable Belief in Danger

The most important thing to understand about the Castle Doctrine is that it does not grant a blanket license to use lethal force. It is also not limited just to the home, depending on the state.

The Castle Doctrine is a concept that all 50 states agree on, at least to some extent. However, there are numerous subtle differences in Castle Doctrine laws across the United States, which can dramatically affect whether an individual can be charged with a crime.

Some states have a Castle Doctrine that only covers your home, whereas other states’ Castle Doctrine protects additional places, such as one’s vehicles.

A key point is that the Castle Doctrine requires that an individual using self-defense must “reasonably believe” that an intruder poses an imminent threat of death, serious bodily injury, or the commission of a forcible felony. To this end, the defender must determine that the deadly physical force was therefore necessary to prevent imminent harm or death to themselves or another person and respond proportionally.

“In any Self-Defense analysis, we are evaluating what a ‘reasonable’ person would have done if they were in your shoes,” said Wittmann.

“Reasonable belief” or “reasonable person” also refers to a hypothetical average person, or someone who uses common sense, exercises ordinary judgment, and reacts proportionally to the situation, Wittmann noted.

She said that, in practice, “reasonable” is determined by the jurors at trial, thereby highlighting the stakes.

“Picture you are at trial and the Jurors, members of your local community, are hearing about your case. They decide if they would have responded the same way you did. The Jurors decide if you acted reasonably under the circumstances,” Wittmann continued. “You still need to show that you did have a real, honest belief that the intruder posed an imminent danger of death or serious physical injury. This is your subjective belief.

“But when we talk about what a reasonable person would have done in your situation, we evaluate it from an objective viewpoint. Would other members of your jury, local community, and the public have thought the same way you did about the threat posed?”

Where You Live Matters — A Lot!

When it comes to firearms and self-defense, there is no substitute for knowledge. Gun owners are expected to know and then observe the laws in their state and their local community. That includes knowing how the Castle Doctrine applies.

It is also something that should never be assumed, regardless of whether the home is in California, New York, Texas, or Montana.

“While all 50 states agree on the concept of Castle Doctrine, there are subtle differences among the states,” warned Wittmann. “For example, the rules can differ regarding when a person is allowed to use deadly force, such as whether it is necessary to wait until an intruder has entered the home, or if an attempted entry alone is sufficient to justify it. It is always important to educate yourself on your state laws, so you know how to act within the legal bounds of your state.”

For example, New York’s Castle Doctrine allows residents to use reasonable force, including deadly force, against an intruder without a duty to retreat if they are inside their home. It does not apply to the surrounding property, where a duty to retreat typically exists. As New York is not a “Stand Your Ground” state, outside the home, individuals generally have a duty to retreat if they can do so safely, including the yard, porch, or driveway.

Other states, such as Michigan, do not require residents to flee or retreat, including the use of reasonable force if an intruder is breaking into a dwelling or business, or attempting to remove someone from a house or car unlawfully. The Castle Doctrine also applies to the curtilage, which is the area around the home, including an attached garage.

Yet, the use of reasonable force is still based on the threat.

“Attached garages are generally covered by the Castle Doctrine protections, while typically detached garages or storage sheds would not qualify for the same protection, though this can vary by state,” said Wittmann. “When it comes to a property theft in garage settings, Castle Doctrine protection is generally limited to situations involving threats to personal safety rather than pure property protection.”

Protecting People Not Property

Using deadly force to stop a car theft would likely not be considered a reasonable use of force unless there was also a threat to an individual. For the same reason, deadly force is not considered reasonable if someone is causing property damage.

There are situations where it can become a bit blurrier.

“The Castle Doctrine and crime prevention statutes both involve the justified use of defensive force, but they apply in distinct legal contexts with differing scopes and thresholds,” suggested Wittmann. “The Castle Doctrine does not protect property; it protects people. Generally, individuals are not allowed to use deadly physical force to protect just personal property.”

Yet, crime prevention statutes, by contrast, do state that a person is justified in threatening or using physical or deadly force against another if they reasonably believe it is immediately necessary to prevent another from committing a specific criminal offense.

It is also important to note that individuals need to understand when an intruder is no longer a threat.

“The Castle Doctrine requires the individual using self-defense to reasonably believe that the intruder poses an imminent threat of death, serious bodily injury, or the commission of a forcible felony,” said Wittmann. “Imminent means ‘right now.’ The Castle Doctrine does not protect individuals pursuing or retaliating against an intruder if the immediate threat has ended.”

Someone attempting to flee, even with items stolen from the house, isn’t an imminent threat any longer.

“If the homeowner no longer has a reasonable belief that the intruder poses an imminent threat of death or serious bodily injury and the person is actively leaving or has left the premises, the homeowner is going to have a much more difficult time arguing that his use of force is justified,” Wittmann continued.

It’s Never a “Get Out of Jail Free Card”

Obviously, the Castle Doctrine should never be viewed as a “get out of jail free card,” and it doesn’t provide blanket immunity for using deadly force in the home. Regardless of the situation, homeowners who used deadly force, even when they viewed it as necessary, should expect an investigation.

The law creates a “rebuttable presumption” of fear, meaning it tilts in favor of the homeowner. Yet, prosecutors can argue that the defender was not actually in reasonable fear for their safety. Likewise, the Castle Doctrine generally does not apply if the person entering has a right to be there (e.g., a co-owner), is a law enforcement officer in performance of duties, or if the homeowner is engaged in illegal activity at the time.

“The Castle Doctrine provides powerful legal protection, but it is not absolute,” explained Wittmann. “Castle Doctrine does not provide a blanket authorization for using deadly physical force in every scenario involving a perceived risk. Remember, the Castle Doctrine is a defense and not a preclusion of prosecution. Self-defense is a justification for an act that would otherwise be a crime.”

Some states have crime prevention statutes that say a person is justified in threatening or using physical or deadly force against another if they reasonably believe it is immediately necessary to prevent another from committing a specific criminal offense. That may include preventing arson of an occupied structure or burglary.

“Any time you act in self-defense in this type of scenario, you should expect and prepare to be the subject of a criminal investigation,” said Wittmann. “The result of the investigation hinges on your set of facts, any statements you choose to make to the police, and your state’s laws.”
