Can You Shoot Someone in Self Defense?

Posted by Sam Israels | Oct 25, 2025

In California, you may use a firearm for self-defense if you reasonably believe it is necessary to avoid imminent death, serious injury, or the commission of a forcible felony.

You can use a firearm for self-defense if you reasonably believe it is necessary to prevent imminent great bodily harm.

The state adopts a stand-your-ground and castle doctrine, so you are not required to retreat before using deadly force if you are in a legally permitted location, like your home. The force used must be proportionate to the threat, and you must not be the first to commit aggression. 

You must reasonably believe that you or someone else faces an imminent threat of death or serious injury. Deadly force is justified only if necessary to prevent that harm, and it must be proportional to the threat. Deadly force cannot be used against minor threats.

Under California's "Stand Your Ground" law, you are not required to retreat before defending yourself in an attack.

The "Castle Doctrine" permits the use of deadly force against an intruder in your home if you genuinely fear for your life or others' safety. Ultimately, your actions will be reviewed for reasonableness by police and courts. 

You can typically use deadly force to protect your home from an intruder, but not solely to defend other property. The castle doctrine does not cover situations where the intruder is fleeing. If you unintentionally shoot a family member or someone you reside with, you might face criminal charges. The court will assess whether your actions were reasonable.

Key Takeaways

  • In California, understanding your rights to self-defense empowers you to defend yourself against an attacker without needing to retreat.
  • Your right to self-defense is protected, providing reassurance as long as the force you use is proportionate to the perceived threat. 
  • You're legally permitted to use a lawful firearm for self-defense if the situation indicates that lethal force is justified.
  • The force applied must correspond to the level of threat. The threat doesn't have to be real if you reasonably believe it is.
  • Deadly force is only allowed if you genuinely fear serious injury or death.
  • Self-defense laws apply to many offenses, such as Penal Code 187 PC for murder, Penal Code 245(a)(1) for assault with a deadly weapon, Penal Code 243(e)(1) for domestic battery, among others.
  • If you used a firearm against that person, you may need to prove that lethal force was justified in the circumstances.
  • Justifiable homicide happens when someone lawfully kills another person under circumstances accepted by California law. The most typical case is self-defense or defending others from an immediate threat of death or serious injury. 

What does Self-Defense Mean?

In California, self-defense is a legal excuse used when someone reasonably believes they are about to be killed, severely harmed, or become a victim of certain violent and heinous crimes. 

The person must reasonably believe that immediate force is necessary to protect against the danger and must use no more force than is reasonably needed. In California, you don't need to prove you acted in self-defense.

Instead, once you assert self-defense, the prosecution must prove beyond a reasonable doubt that you did not act in self-defense. Typically, three main elements are required to establish a claim of self-defense:

  1. Imminent danger refers to a threat that is immediate and present, not just potential or expected in the future.
  2. The fear of harm should be justified; a typical person in a similar situation would experience the same concern.
  3. The use of force in self-defense should be proportional to the level of threat encountered.

Self-defense is categorized as an 'affirmative defense,' a legal term that indicates that while you acknowledge breaking the law by using physical force against someone, your actions are justified. This means that you are not denying the charges against you, but you are providing a legal justification for your actions.

As noted, California law includes two key principles that can influence a self-defense claim: Stand Your Ground and the Castle Doctrine.

California's Stand Your Ground Law

Unlike states with explicit "stand your ground" laws, California lacks a specific statute for this principle. However, the state acknowledges the right to stand your ground in certain scenarios.

In self-defense cases outside your home, you are not required to retreat before using force to protect yourself or others. This understanding is based on case law, not a dedicated law. The essential point is that any use of force, including lethal force, must be reasonable and necessary given the circumstances.

The Castle Doctrine in California

California law explicitly recognizes the castle doctrine, which permits individuals to use force, including deadly force, without the obligation to retreat when they are in their home and an intruder unlawfully enters or attempts to do so.

This doctrine is founded on the belief that your home is your castle and that you have the right to defend it. Unlike standing your ground in public, the Castle Doctrine does not necessarily require you to demonstrate a perceived need for deadly force.

If someone breaks into your home by force, you have the right to assume it's a lethal threat, and you're allowed to respond with lethal force (including the use of a firearm). There is no duty to retreat, even if a safe retreat is possible.

What is the Stance on Using Firearms and Lethal Force?

Since a firearm can cause death, employing it in self-defense involves considering lethal force. Lethal force is only legally justified when it's necessary to prevent imminent death or serious injury to oneself or others.

Lethal Force

Using a gun inherently escalates the threat level to potentially lethal due to its deadly nature. Consequently, the law mandates a high threshold of danger to justify its use.

Before using lethal force, one must reasonably conclude that less severe methods of defense would not work. This judgment must be made quickly, and hindsight is not available to those making rapid decisions in dangerous, life-threatening circumstances.

However, the legal review of using lethal force will carefully assess if the threat was immediate and the response proportional. In California, you are legally permitted to use deadly force in self-defense when certain conditions are met:

  • You reasonably believed that you or another person faced imminent danger of serious injury, death, or becoming a victim of a violent and wicked crime.
  • You believed that lethal force was necessary to mitigate the threat and prevent harm.
  • You applied no more force than what was reasonably necessary to prevent the harm.

Why Should You Hire an Experienced Attorney? 

Using a firearm in self-defense can be legal in specific situations, but may still lead to serious legal repercussions. An investigation is likely to determine if your actions were justified. If it is found that your actions exceeded legal self-defense limits, you could face criminal charges.

Because using a firearm in self-defense carries significant consequences—even when you're legally justified—it's advisable to consult with an experienced California criminal defense attorney.
