Self-Defense Claims in Colorado: Understanding Your Rights Under the Law

When someone is charged with assault or a violent crime in Colorado, one of the most critical questions is whether the use of force was legally justified. Colorado law recognizes the right to self-defense, but the rules governing when and how much force you can use are more nuanced than most people realize. As a defense attorney who has tried numerous assault cases, I want to walk through the key principles that govern self-defense claims in this state.

The Basic Standard for Self-Defense

Under Colorado Revised Statutes section 18-1-704, a person is justified in using physical force against another person when they reasonably believe it is necessary to defend themselves or a third person from the imminent use of unlawful physical force. The key elements here are reasonableness and imminence. The threat must be happening or about to happen — not something that occurred in the past or might happen in the future. And your belief that force was necessary must be one that a reasonable person in your situation would share.

This means that self-defense is not a blank check. You cannot use force in retaliation, and you cannot escalate a situation and then claim you were defending yourself. The law looks at the totality of the circumstances to determine whether your response was proportional to the threat you faced.

When Deadly Force Is Justified

Colorado law permits the use of deadly force in self-defense only under more limited circumstances. You may use deadly force if you reasonably believe a lesser degree of force would be inadequate and you have reasonable grounds to believe that you or another person are in imminent danger of being killed or suffering great bodily injury. Deadly force is also justified to prevent the commission of certain serious felonies, including kidnapping, sexual assault, robbery, and first-degree arson.

Importantly, Colorado does not impose a general duty to retreat before using force, including deadly force, in public. This is sometimes informally referred to as a “stand your ground” principle, though Colorado’s statute does not use that phrase. You are permitted to stand your ground and defend yourself where you have a legal right to be, as long as the other requirements for justified force are met.

The Make My Day Law

Colorado’s so-called “Make My Day” law, codified at C.R.S. section 18-1-704.5, provides even broader protections for the use of force inside your own home. Under this statute, any occupant of a dwelling is justified in using any degree of physical force — including deadly force — against a person who has made an unlawful entry into the dwelling, if the occupant has a reasonable belief that the intruder has committed or intends to commit a crime in addition to the uninvited entry and might use any physical force, no matter how slight, against any occupant.

The Make My Day law creates a strong presumption in favor of the homeowner. It provides immunity from criminal prosecution and civil liability when its conditions are met. However, the law applies specifically to dwellings — not to detached garages, yards, or businesses. Understanding the boundaries of this statute is critical if you are involved in a use-of-force incident in or around your home.

How Self-Defense Works in Court

In Colorado, self-defense is an affirmative defense. This means that the defendant bears the initial burden of producing some credible evidence to support the claim. Once that evidence is presented, the burden shifts to the prosecution to disprove self-defense beyond a reasonable doubt. This is a significant advantage for the defense — the state must convince the jury that your use of force was not justified.

Building a strong self-defense case requires careful documentation of the circumstances: witness statements, physical evidence, surveillance footage, medical records, and anything else that supports the reasonableness of your actions. An experienced defense attorney will begin gathering this evidence immediately, before it disappears or memories fade.

The Stakes Are High

Assault charges in Colorado range from misdemeanors to serious felonies carrying years in prison. If you were acting in self-defense, the facts and evidence supporting that claim need to be presented effectively from the earliest stages of your case. Prosecutors do not always get it right, and people who were genuinely defending themselves do get charged.

If you are facing assault charges and believe you acted in self-defense, consult with a criminal defense attorney who has experience trying these cases. The difference between a conviction and a justified use of force often comes down to how well the defense is prepared and presented.
