Can I Use Self-Defense If I Was Defending Someone Else?

Understanding the Defense of Others in Criminal Law

In California, the defense of others falls under Penal Code § 197. This law lets you use force to defend someone else from unlawful force, just like you can use self-defense to protect yourself. But defending someone else is trickier because you might not see how the fight started.

When you step in to defend a third person, you take on legal risk. If you misread the situation—maybe the person you thought was the victim actually started the fight—you could face criminal charges despite your good intentions. Without proper legal defense, your attempt to help could lead to serious trouble.

The self-defense doctrine extends to protecting others, but with clear limits. Your actions must match what a reasonable person would do in that situation based on what you knew at the time. In most states, to successfully claim self-defense when defending someone else, the circumstances must justify such force. This means that if the situation involves a forcible felony, like a violent crime or sexual assault, the use of deadly force might be justified.

However, if your actions result in physical contact that is deemed excessive, you could face arrest. It’s crucial to have a strong attorney-client relationship to navigate the complexities of these cases, as reasonable doubt can significantly change the outcome of your legal defense. A skilled criminal defense attorney can help you understand the nuances of the law, ensuring your actions are seen within the proper context, whether it involves a police officer intervening or a civilian stepping in during an argument.

When Can You Legally Defend Someone Else?

The legal right to defend someone else has strict rules. California law sets specific conditions that must be met before you can legally use force to protect another person. If you don’t meet these conditions, you might face criminal charges even if you were trying to help.

These requirements help courts decide if your use of force was reasonable or if you should face charges. Understanding these rules can keep you from turning from protector to defendant.

Imminent Danger Requirement

For the defense of others to work as a legal defense, the person you protected must have faced imminent danger. “Imminent” means the threat was about to happen right now — not something that might happen later. If someone is actively attacking another person, the danger is imminent. But if someone just made verbal threats earlier, that’s not imminent danger.

The threat must be happening or about to happen immediately. Courts look at whether a reasonable person would believe the danger was right now rather than a future threat. This timing matters—if you use force to stop something you think might happen later, you likely won’t be protected under the defense of others.

Reasonable Belief of Harm Standard

Your belief that the person needed protection must be reasonable. This means you truly believed they were in danger (your personal view) and that a typical reasonable person would have thought the same thing (what most people would think).

In People v. Humphrey, California courts ruled that what matters is what you reasonably believed when it happened, even if you turned out to be wrong. For example, if you see what looks like a deadly weapon and defend someone else, your actions might be justified even if it wasn’t really a weapon.

Defending Against Deadly vs. Non-Deadly Threats

The force you can legally use depends on the threat level. Against non-deadly threats, you may only use non-deadly force. For deadly threats—those risking death or great bodily harm—you may be justified in using deadly force to defend the other person.

You must match your level of force to the threat. If someone threatens another person with a fist, using a baseball bat or knife would likely be too much force. But if the aggressor uses a weapon that could cause serious bodily harm, using greater force might be justified to protect the person’s life.

The Role of Force in Defense of Others

When protecting others, using the right amount of force is key. You can’t just hurt someone because they pose some threat to another person. California law requires that you use proportional force, even in emergencies. Knowing these rules can keep you from facing charges for excessive force.

Here are the main rules about force when defending others from harm.

Proportional Force Explained

When defending someone else, you must use force proportional to the threat. This means your response should match the danger level. If someone pushes another person, pushing the aggressor back might be okay, but hitting them with an object would likely be too much.

Courts look at whether your force was right for the situation based on what you knew then. Using more force than needed can lead to assault charges, even if you were trying to help. A criminal defense attorney can explain how your case fits with legal standards for reasonable force.

When Deadly Force is Justified

California Penal Code § 197 explains when deadly force is allowed in defense of others. You can only use deadly force when protecting someone from imminent death or great bodily injury, and when less force wouldn’t work.

Court records show many cases where deadly force was justified when the victim faced death or great bodily harm and no other option would stop the attack in time. But even in these cases, the person who used deadly force needed a strong legal defense to prove their actions were necessary.

Limits on Protecting Others

There are important limits on your right to defend others. You can’t claim the defense of others if you’re protecting someone who started the fight or was committing a crime. For example, you can’t legally defend someone who attacked another person first and is now losing the fight.

You also must stop using force once the threat ends, such as when an aggressor backs off or can’t fight anymore; continuing to use force changes you from defender to aggressor. This difference often decides whether actions count as legal defense or criminal assault with bodily harm.

Criminal Charges You Might Face

Despite good intentions, defending someone else can lead to serious criminal charges if authorities think you used too much force. These charges range from misdemeanors to felonies, with heavy penalties.

Common charges include assault (PC 240), battery (PC 242), and aggravated assault (PC 245) if weapons were involved. If the aggressor suffered serious injuries, you might face charges with great bodily injury enhancements, adding years to a sentence. In cases where your actions caused death, you could face manslaughter or murder charges.

The court will examine if you had a reasonable belief of danger, if you used proportional force, and if you stopped using force when the threat ended. They’ll also check if you have other options besides force. This shows why quick legal help is vital—evidence collected right after the incident can greatly affect your case.

How a Criminal Defense Attorney Makes All the Difference

When facing charges after defending someone else, your choice of legal help strongly impacts your case outcome. The right criminal defense attorney brings special knowledge of self-defense laws that can determine the difference between conviction and acquittal.

Defending yourself in court leaves you open to mistakes and prosecution tactics meant to weaken the defense of others’ claims. Public defenders often handle too many cases at once, limiting their ability to build the best defense. At Summit Defense, we focus only on criminal defense with attorneys who specialize in self-defense and defense of other cases.

Court records show that defendants with private criminal defense attorneys are more likely to have charges reduced or dismissed in self-defense cases than those with public defenders or no attorney. This difference often comes down to the attorney’s ability to gather evidence and prepare a strong affirmative defense strategy.

California’s Stand Your Ground Laws

Unlike some states, California doesn’t require you to try to run away before defending yourself or others. This affects how courts view cases where someone steps in to protect another person. Understanding these laws is key to building a strong legal defense.

No Duty to Retreat in California

California follows a “no duty to retreat” rule. This means neither you nor the person you’re defending must try to escape before using reasonable force for protection. Under Civil Code § 50, a person facing attack may stand their ground and defend themselves or others.

This doesn’t give unlimited permission to use force—actions must still be reasonable. While you don’t need to try to run away first, if you could have safely avoided the fight, this might affect how a jury views your claim of defense of others, especially if you used deadly force.

Limitations on Defense of Others

Special rules apply when defending others on the property. While the castle doctrine gives more protection when defending against home intruders, different standards apply in public places or when defending someone else’s property.

You might also face a lawsuit even if you avoid criminal charges. The person you used force against may sue you for damages, regardless of your criminal case outcome. This creates a complex situation where actions justified under criminal law might still result in civil penalties.

Building Your Legal Defense

Creating a strong defense after being charged for protecting someone else requires careful planning. A good strategy greatly improves your chances of a favorable outcome when facing criminal charges for what you believe was justified protection.

Gather all evidence about the incident, including what made you believe the other person was in danger. Find witnesses who saw what happened, as their testimony can support your view of the threat. Get medical reports if anyone was hurt, as these can back up your story.

Keep any physical evidence from the scene. Check for security cameras that might have recorded the incident. Your defense attorney should review police reports for mistakes or missing information that might help your case.
