Colorado Assault Laws
Assault charges in Colorado carry consequences that extend well beyond the courtroom. A conviction can affect employment, housing, professional licenses, immigration status, and relationships in ways that follow a person for years. Understanding how Colorado assault laws actually work, not in the abstract but in the specific way prosecutors charge and pursue these cases, is the first step toward building a defense that addresses the actual situation you are facing.
Colorado classifies assault offenses across three degrees, and the degree charged determines everything: which court hears the case, what sentence is possible, and whether the offense is treated as a misdemeanor or a felony. The facts that drive those distinctions, the alleged seriousness of injury, the presence of a weapon, the identity of the alleged victim, and the accused person’s intent at the time, are all subject to scrutiny, investigation, and challenge. What a police report says happened and what actually happened are often two different things, and that gap is where defense work begins.
Reid DeChant has defended clients facing assault charges ranging from disputed arguments that escalated into third-degree misdemeanor allegations to serious felony cases involving accusations of assault with a deadly weapon. He has tried these cases to verdict in Denver, Adams, Arapahoe, Jefferson, Douglas, and Broomfield County courts, and he understands how local prosecutors approach evidence, witnesses, and plea negotiations in assault cases. This page walks through how Colorado law defines assault, what the stakes look like at each level, and what to do if you or someone you know is facing these charges.
How Colorado Defines the Three Degrees of Assault
Colorado’s assault statutes divide the offense into three distinct degrees, each with its own elements, penalties, and procedural path. Understanding where your case falls within that framework matters from the very beginning, because it shapes the charging document, the available defenses, and the realistic range of outcomes.
First-degree assault is the most serious. It requires that the prosecution prove the person intentionally caused serious bodily injury to another using a deadly weapon, or that they intended to disfigure, destroy, or amputate a body part. First-degree assault is a class 3 felony and is treated as a crime of violence under Colorado law when a deadly weapon is used, which triggers mandatory prison time if the person is convicted. Colorado courts take these cases seriously, and the mandatory sentencing provisions limit a judge’s discretion in ways that make early defense intervention especially important.
Second-degree assault covers a broader range of conduct. A person can be charged with second-degree assault for recklessly causing serious bodily injury with a deadly weapon, for intentionally causing bodily injury using a deadly weapon, for applying physical force to a peace officer, firefighter, or emergency medical service provider, or for causing bodily injury with intent to prevent a police officer from performing their duties. Second-degree assault is generally a class 4 felony, though when it qualifies as a crime of violence, mandatory sentencing provisions apply there as well. The presence of a law enforcement victim or a weapon changes the calculus significantly.
Third-degree assault is a class 1 misdemeanor, which is the least severe classification but should not be treated as minor. It applies when a person knowingly or recklessly causes bodily injury to another, or intentionally causes physical contact that a reasonable person would find offensive. Third-degree assault is extremely common in domestic violence situations, bar altercations, and disputes between neighbors or coworkers. A conviction still carries potential jail time, mandatory treatment programs in domestic violence contexts, and a permanent criminal record.
Common Assault Charge Situations and the Laws Behind Them
- Domestic Violence Assault Allegations: When the alleged victim is a current or former intimate partner, family member, or household member, a mandatory arrest protocol often applies under Colorado law, and the DA’s office frequently pursues these cases even when the complaining witness recants or refuses to cooperate.
- Assault on a Peace Officer: Under Colorado’s second-degree assault statute, making physical contact with a law enforcement officer in the line of duty, even without causing serious injury, can result in a felony charge and eliminate many diversion and dismissal options that would otherwise be available.
- Bar and Nightlife Altercations: Fights near Denver venues in LoDo, RiNo, and Colfax corridor frequently generate third-degree assault charges based on witness accounts and surveillance footage that may be incomplete, contradictory, or taken out of context.
- Mutual Combat and Self-Defense: Colorado law permits the use of physical force in self-defense when a person reasonably believes it is necessary to defend against another’s use or imminent use of unlawful physical force. Determining which party was the aggressor is often genuinely contested, and the self-defense analysis can change the entire direction of a case.
- Strangulation Charges: Strangulation is treated as a form of assault under Colorado law and is taken extremely seriously by prosecutors, particularly in domestic violence cases. The science around strangulation injuries and delayed symptom presentation is something a defense attorney must understand and be prepared to challenge.
- Assault with a Deadly Weapon: Introducing a weapon into an assault allegation elevates the degree and frequently triggers crime-of-violence sentencing. Prosecutors sometimes characterize everyday objects as deadly weapons based on how they were allegedly used, and those characterizations are subject to challenge.
- Vehicular Assault: Colorado maintains a separate vehicular assault statute that applies when a driver causes serious bodily injury while driving under the influence or while driving recklessly. These cases often overlap with DUI charges and carry felony-level consequences.
What to Do If You Are Facing Assault Charges in Colorado
The first and most pressing concern after an assault arrest is the conditions of your release. In Colorado, many assault cases, especially those involving domestic violence allegations, result in mandatory protection orders issued at the time of first appearance. Violating those orders, even unintentionally, creates a separate criminal exposure. Understanding exactly what the order requires is not optional. If you do not have a clear copy of your protection order or do not understand its terms, that needs to be addressed before anything else.
Assault cases filed in Denver County are handled at the Lindsey-Flanigan Courthouse at 520 West Colfax Avenue. Cases in Adams County go through the Adams County Justice Center in Brighton. Jefferson County assault cases are heard in Golden, and Arapahoe County cases proceed through the Arapahoe County Justice Center in Centennial. Knowing which court has jurisdiction over your case tells you which prosecutor’s office is handling the file and, often, what their typical approach to assault cases looks like.
Gather whatever documentation you have access to immediately. Text messages, emails, social media records, photos, and witness contact information can all be critical. Physical evidence disappears and witnesses’ memories fade quickly. If the incident happened at a business or public location, surveillance footage may be overwritten within days. Security camera retention periods in Colorado vary, and footage that could help your defense may not exist a week from now.
One of the most common mistakes people make in assault cases is speaking to police or investigators without an attorney present. Whether or not you believe you acted in self-defense or were falsely accused, the statements you make before you have counsel can be used against you in ways that are difficult to undo. This is especially true in domestic violence cases, where any statement is likely to be recorded and reviewed carefully by prosecutors.
In domestic violence assault cases specifically, the DA’s office in Denver and surrounding counties does not require the alleged victim to “press charges” in order to proceed. Prosecutors make that decision independently based on the available evidence. If you are hoping the case will go away because the complaining witness changed their mind, that may not happen, and you should not proceed without legal guidance on that assumption.
Why DeChant Law Handles Colorado Assault Defense Differently
Reid DeChant’s background as a public defender gave him direct experience with the full spectrum of assault charges, from third-degree misdemeanor allegations through felony assault cases involving weapons and serious injury. That volume of courtroom work, across Denver, Adams, and Broomfield County courts, produced the kind of practical knowledge about how prosecutors build cases and how juries evaluate credibility that cannot be taught in a classroom.
Reid is a graduate of the Trial Lawyers College, the program founded by legendary attorney Gerry Spence that trains lawyers to connect with juries through authentic human storytelling rather than technical legal argument. Assault cases are almost always credibility contests. The jury is deciding who to believe, what really happened, and whether the person on trial acted out of genuine fear or legitimate defense rather than aggression. Those are human questions, and answering them requires more than filing motions. It requires a lawyer who knows how to speak to twelve strangers in a way that resonates.
The firm’s case results reflect that approach. Reid has secured Not Guilty verdicts in assault cases tried to juries, including two counts of assault with a deadly weapon resulting in acquittal, a third-degree assault and false imprisonment domestic violence case resulting in not guilty at trial, and an Adams County assault case that ended in not guilty at trial. He has also obtained dismissals of felony assault charges, including a felony menacing domestic violence case dismissed upon motion. As always, past results do not guarantee future performance, but they do reflect a defense practice built around going to trial when that is what the situation calls for.
Reid is a member of the National Association of Criminal Defense Lawyers and the Colorado Criminal Defense Bar, staying connected to the evolving strategies, legal challenges, and legislative changes that affect how assault cases are litigated across the state. When you work with an assault defense attorney in Colorado who treats your case like a person rather than a file, those memberships translate into real-world knowledge that makes a difference.
Questions People Have About Colorado Assault Charges
What is the difference between bodily injury and serious bodily injury in Colorado?
These are defined terms under Colorado law, and the distinction between them can determine whether someone faces a misdemeanor or a felony. Bodily injury generally means physical pain, illness, or impairment of a physical or mental condition. Serious bodily injury involves a substantial risk of death, permanent disfigurement, or protracted loss or impairment of a body part or organ. Prosecutors sometimes argue that injuries are more severe than they are. Medical records, expert testimony, and the actual treatment the alleged victim received are all relevant to this analysis.
Can I be charged with assault if the other person was not physically injured?
Yes. Third-degree assault can be charged based on contact that a reasonable person would find offensive, even if no injury resulted. Additionally, charges like felony menacing, which is closely related to assault, do not require physical contact at all. These charges are sometimes filed when an alleged victim reports feeling threatened, even without any physical altercation.
What happens if I acted in self-defense?
Colorado law recognizes the right to use physical force to defend yourself against another person’s unlawful physical force. The force used in defense must be proportional to the threat. If a jury accepts your self-defense claim, you are entitled to an acquittal. However, the prosecution will challenge the reasonableness of your belief that force was necessary and the proportionality of your response. Self-defense cases require careful preparation and usually turn on which version of the confrontation is more credible.
Will I be required to attend treatment or counseling if convicted of assault?
In domestic violence assault cases, mandatory treatment is almost always part of any probationary sentence in Colorado. Even in non-domestic cases, a judge may order anger management or other counseling as a condition of probation. Understanding what probation actually looks like for your specific charge matters when evaluating whether to accept a plea offer.
Does an assault conviction affect my ability to possess firearms in Colorado?
A conviction for assault categorized as a felony will prohibit you from possessing firearms under both federal and Colorado law. Even misdemeanor domestic violence assault convictions trigger a federal firearms prohibition. These collateral consequences are permanent and do not disappear after completing a sentence, which is one reason why fighting the charge or pursuing dismissal matters so much.
What happens if the alleged victim does not want to cooperate with the prosecution?
Colorado prosecutors, especially in domestic violence assault cases, are trained to pursue charges regardless of witness cooperation. They may rely on photographs, medical records, recorded calls, prior incident reports, or officer observations to build a case without the alleged victim’s testimony. A witness can also be subpoenaed to testify even if they do not want to. Do not assume the case will disappear because the alleged victim is not cooperating.
Can an assault charge be expunged or sealed in Colorado?
Colorado’s record sealing laws allow for sealing of certain criminal records, including dismissed charges and, in some cases, convictions, depending on the offense and the amount of time that has passed. Assault convictions that result in felony records are more difficult to seal. An attorney can assess whether your specific situation qualifies for sealing and what that process looks like under current Colorado law.
How does a prior assault charge affect a new case?
A prior assault conviction, even one that is years old, can be used by prosecutors to argue for harsher sentencing, to challenge character evidence, or in some circumstances to demonstrate a pattern of conduct. Prior domestic violence convictions in particular can elevate the classification of new domestic violence offenses. Your history matters in ways that are not always obvious, which is another reason to address every charge seriously the first time.
What if the assault allegation arose from a mutual fight where both parties participated?
Colorado law does not recognize mutual consent to a fight as an automatic defense to assault. However, mutual combat situations genuinely complicate the prosecution’s ability to establish who was the aggressor and whether your actions were offensive or defensive. These cases often come down to the credibility of witnesses, including the parties themselves, and the physical evidence. Cross-examination of the complaining witness about their own conduct can be a powerful defense tool.
How long does a felony assault case typically take in Denver-area courts?
Felony assault cases in Denver County and the surrounding jurisdictions routinely take anywhere from several months to well over a year from arrest to resolution, depending on whether the case goes to trial. Preliminary hearings, discovery, motions practice, and trial scheduling all add time. Cases that settle through a plea agreement tend to resolve faster, but whether a plea is the right path depends entirely on the strength of the evidence and your individual circumstances. Rushing to resolve a felony charge without fully understanding the options is rarely a sound approach.
