Colorado’s Mandatory Arrest Domestic Violence Law: Know Your Rights

Colorado’s Mandatory Arrest Domestic Violence Law: Do You Know Your Rights?

By H. Michael Steinberg, A Colorado Criminal Defense Lawyer – Practicing Colorado Criminal Law in the courts of Colorado for over 40 years.

Introduction:

In most of Colorado’s neighboring states, an officer responding to a heated domestic argument has discretion to make an arrest or not to make one, or let things cool off between the parties for the night.

In domestic violence cases, Colorado and several other states in this country are different. Colorado is a mandatory-arrest state, and once an officer has probable cause, the decision to arrest is no longer a choice — it is a legal command or mandate.

The law does not say an officer ‘may’ arrest. It says the officer ‘shall’ arrest. That single word removes the discretion most people assume exists at the scene of a family or relationship dispute.

The Statute: C.R.S. § 18-6-803.6

Colorado’s mandatory arrest requirement is codified at C.R.S. § 18-6-803.6. It provides that when a peace officer determines there is probable cause to believe a crime involving domestic violence has been committed, the officer shall, without undue delay, arrest the person believed to have committed it and charge the appropriate offense.

C.R.S. § 18-6-803.6(1)

“When a peace officer determines that there is probable cause to believe that a crime or offense involving domestic violence … has been committed, the officer shall, without undue delay, arrest the person suspected of its commission … and charge the person with the appropriate crime or offense.”

Understanding exactly how this law works and which rights survive the process may mean the difference between a defensible case and a devastating one.

This article is intended to walk the reader through C.R.S. § 18-6-803.6′s “shall arrest” language, the broad “intimate relationship” definition under
§ 18-6-800.3, how officers determine the predominant aggressor in mutual-combat calls, why there’s no immediate bond and how the mandatory protection order is imposed under § 18-1-1001 works (including the firearm relinquishment piece), the habitual-offender felony enhancement under § 18-6-801(7), and closes with a “know your rights” section aimed at people who’ve just been arrested.

If you live in Colorado, the phrase “mandatory arrest law” in a domestic violence investigation is one of those things you might hear but may not fully grasp the significance of the law.

Colorado does, in fact, have a mandatory arrest rule for domestic violence cases. I know how it has changed the face of domestic violence investigations from the early 1980s, when I began my career as a young prosecutor in Arapahoe and Douglas Counties.

Briefly, the law changed how police respond, how fast things escalate, and what a person who is the focus of a Colorado domestic violence investigation should and should not say or do in the moment.

Since a Domestic Violence (DV) arrest can affect your job, your housing, your gun rights, and your ability to see your children, it’s worth understanding the basics before you ever need them.

Some Shorthand Notes On The Mandatory Arrest Law In Colorado Domestic Violence Cases

Situation	Mandatory arrest?
Verbal argument with no alleged crime and no probable cause	No statutory requirement to arrest.
Officer finds probable cause for assault, harassment, criminal mischief, stalking, or another offense involving domestic violence	Yes—arrest is required without undue delay.
Both parties claim harm	Not automatically; police must evaluate the allegations, injuries, future risk, and self-defense separately.

What “Domestic Violence” Means In Colorado

In Colorado, “domestic violence” is not a standalone crime by itself. It’s a label, kind of an add-on, that attaches to other charges.

A lot of people think DV only means spouses or partners. Colorado’s definition is much broader. It covers acts (or threats) between people in an “intimate relationship,” which can include:

Married spouses.
Unmarried partners.
People who are dating or used to date.
People who have a child together.
People who live together or used to live together in that kind of relationship.

The conduct can extend beyond physical violence. Colorado law generally frames domestic violence around an act or threatened act of violence, or other crime, used as a method of coercion, control, punishment, intimidation, or revenge against someone in that relationship.

Yes, domestic violence can involve an act of assault, but it can also be harassment, property damage, stalking, violation of a protection order, and other charges that happen in a domestic context but are not, by commonly understood definition, violent.

Which is why these cases can come out of altercations and other arguments that, honestly, do not seem to fit the definition of what most people picture as “domestic violence.” I have recently written on the complexity of the term domestic violence and the nature of “intimate relationships.”

What The “Mandatory Arrest” Rule Actually Means

Colorado law requires law enforcement to arrest a person in certain DV situations. In plain English, if police have probable cause to believe domestic violence occurred, they are generally required to make an arrest.

That’s the key phrase: probable cause. Not proof beyond a reasonable doubt. Not “the other person insists.” Not “someone is more emotional.”

Probable cause (blue below) is based on what the officers see and hear; is there a reasonable basis to believe a DV crime happened?

Colorado Criminal Burdens of Proof

This is why DV calls feel like they move fast. Officers are trained to look for indicators quickly:

Injuries, marks, swelling, scratches.
Broken items, damaged doors, holes in walls.
911 call recordings and what was said on the call or calls.
Statements from each person.
Statements from children, if present, neighbors, roommates.
Prior law enforcement calls to the address.
Texts, voicemails, social media messages located at the scene.
The overall story, whether it seems to change, whether it fits the physical evidence, if any, at the scene.

Once the police find they have probable cause to arrest, the “mandatory” part of the law is then triggered.

Domestic violence cases are expedited by Colorado district attorneys. Prosecutors expedite the evaluation of police reports and the filing of formal charges, which may differ from the charges that the arresting officers recorded. Occasionally, the charges are reduced, while at other times they are increased, with the addition of false arrest and harassment.

“We Both Ask That No One Be Arrested.”

This is the part that shocks people.

The alleged victim of domestic violence does not control whether an arrest happens. If the police believe there’s probable cause, they can and will arrest even if the other person is pleading with them not to.

It should be noted that it is common for someone to call 911 in the heat of the moment and then immediately regret it. Officers know that; however, they still must make a decision within the mandatory arrest framework.

Dual Arrests In Colorado Domestic Violence Cases: Can Police Arrest Both People?

They can, but Colorado law pushes officers to avoid “dual arrests” unless there’s a real basis for it. In many situations, police are expected to try to identify a primary aggressor.

That analysis can include:

Who appears to have caused injuries and the severity.
Any prior history of violence or threats between the parties.
Size and strength differences (not always an issue, but it can be a factor).
Who seems to be controlling or intimidating the other.
Which party, if either, appears to have acted in self-defense

Still, dual arrests can happen. Especially when both people have marks, both people accuse each other, or the scene is chaotic and appears to be a mutual assault.

Some information that may help protect against mistaken prosecution: if you have visible injuries, take photos as soon as you can safely do so. If you can’t, have your lawyer request jail intake photos, body cam, and any scene photos. Evidence may disappear quickly in DV cases.

A Closer Look At Determining the “Predominant Aggressor”

Mutual combat calls — where both people report the other struck first, or both show signs of a physical altercation — are common, and the statute anticipates them. Officers are directed to evaluate each person’s account separately and identify the predominant, or primary, aggressor rather than automatically arresting both parties or defaulting to whoever called 911 first.

This determination is made in minutes at the scene, often based on incomplete information, visible injuries that do not reflect who instigated the encounter, and the relative composure of the two people the officer is speaking with.

A predominant aggressor finding made in the heat of the moment is not the end of the case — it is frequently the first fact a defense attorney needs to unpack.

The statute explicitly does not require an officer to arrest both parties when each claims to have been the victim, nor does it require an arrest at all where the officer finds no probable cause. Mandatory arrest is not the same as automatically arresting everyone present.

Your Rights During A Domestic Violence Police Response

This is where people may accidentally make their case worse, in the absence of understanding what rights they have and steps they may take to protect themselves.

1. You have the right to remain silent.

You do not have to explain, justify, or “clear it up.” Trying to talk your way out at the scene often backfires.

You can say something like:

I want to cooperate, but I’m going to remain silent, and I want a lawyer.

Say it calmly. Then stop talking.

Police may ask to come in, look around, check bedrooms, check your phone messages, etc.

You can and should refuse consent. They might still conduct a search under a legal exception (such as exigent circumstances) or obtain a warrant later. But do not voluntarily expand their investigation.

A simple line:

“I do not consent to any searches.”

3. You have the right to an attorney.

Ask for a lawyer early and often. If you’re arrested, also be certain not to discuss the incident on jail-originated phone calls. Those calls are recorded. People forget this and then basically hand the prosecution a clean audio confession.

4. You have the right to medical care.

If you’re injured, ask for medical evaluation. Again, this can matter both for your health and for documenting the facts of what happened.

What Happens After the Arrest (And Why Domestic Violence Cases Can Feel “Automatic”).

After an arrest with a DV designation, a few things happen in Colorado almost routinely.

There Is No Immediate Right To Bond

Unlike many arrests, a person booked on a domestic violence allegation generally cannot simply post bond and leave. Colorado law requires that a bond-setting or advisement hearing occur, and that a mandatory protection order be entered under C.R.S. § 18-1-1001 before release.

In practice, this means most people arrested on a DV allegation spend at least one night in custody awaiting the next available court session, and hearings are held within 48 hours of booking — including on weekends and holidays — so that the delay is not indefinite.

A Full No-Contact Mandatory Protection Order Is Normally Issued

In most Colorado DV cases, the court issues a Mandatory Protection Order (MPO) at the time of the Judge’s advisement and at the bail bond hearing. You will often hear it called a restraining order, a no-contact order, or a protection order.

Every domestic violence case in Colorado automatically triggers a protection order under C.R.S. § 18-1-1001, typically restraining the accused from any contact with the alleged victim for the duration of the case. This order is issued as a matter of course, before guilt or innocence is ever addressed, and violating it — even at the alleged victim’s invitation — is a separate, new criminal offense under C.R.S. § 18-6-803.5.

This order can include:

No contact with the alleged victim, direct or indirect.
No return to your home, even if it’s your lease, your mortgage, your possessions (without a police “civil assist”).
No firearms or weapons possession.
Limits on seeing children or even being at certain locations.

Violating the protection order is a serious problem in itself. Even a “friendly” text like “I’m sorry” can be charged as a violation, even if the other person asked you to text.

While the protected party can also get in trouble in certain very limited situations, in practical terms, the defendant is the one at risk.

Firearms Issues Are Addressed Immediately

Colorado protection orders commonly include firearm restrictions. And federal law can also come into play, depending on the exact order and case posture.

A requirement to refrain from purchasing or possessing firearms, and to relinquish any firearms already in the accused’s control, when the case involves the threat or use of physical force

If you own guns, work in security, law enforcement, or anything involving weapons, you need to address this early with counsel. Do not just assume it will “work itself out.”

You May Be Removed From Your Home

This is one of the most disruptive consequences. Even if you were not the person who called 911. Even if you pay the rent or mortgage. The MPO can still bar you from returning.

If you need belongings, you typically need a civil standby or a court-approved arrangement. Don’t just show up. That can lead to another arrest.

Can the Mandatory Protection Order Be Modified?

Sometimes, yes. Not always quickly, and not automatically.

Courts can modify conditions (for example, allowing limited contact for child exchanges, or allowing peaceful contact) but it depends on the judge, the facts, the alleged victim’s stance, and what the prosecutor argues.

Important detail: even if the protected party wants contact, you still need the court to modify the order. Otherwise, you’re the one violating it.

“If The Alleged Victim Doesn’t Want To Press Charges, The Charges Go Away.” This Is Not True.

Another big misconception.

In Colorado, the case is prosecuted by the state. The alleged victim is a witness, not the decision maker. Prosecutors can and do proceed even when the other person recants, doesn’t cooperate, or says it was a misunderstanding.

How? The DA uses the existing evidence.

They may use:

911 recordings.
Body cam footage.
Photos of injuries or the scene.
Medical records.
Text messages and voicemails.
Excited utterances (statements made during the incident).
Prior incidents (sometimes, depending on rules of evidence).

This is why it’s dangerous to assume the case dies if the relationship “goes back to normal.”

This is the single most common misunderstanding in these cases. Once a mandatory arrest occurs, the decision to prosecute belongs to the District Attorney’s Office, not the alleged victim.

A complainant who calls the prosecutor’s office, submits a written statement, or shows up to court asking that the case be dismissed does not control the outcome. Prosecutors routinely proceed, as noted above, on the strength of the initial police report, 911 audio, photographs, and officer testimony even when the complaining witness later recants or becomes uncooperative.

This does not mean a recantation or a change in the complaining witness’s account is irrelevant — it can be powerful evidence for the defense — but it means a case is rarely resolved by the alleged victim’s wishes alone, and anyone who assumes the case will simply “go away” on that basis is operating under a serious misunderstanding of how these cases proceed.

Self-Defense in Colorado Domestic Violence Cases

People have the right to defend themselves. But self-defense claims need evidence, not just the statement “I was defending myself.”

Helpful evidence can include:

Your injuries documented quickly.
A consistent timeline (your lawyer can help you present it properly).
Witnesses who saw the other person act aggressively.
Prior threats documented in texts.
Medical records.
Any video footage (doorbell cameras, neighbors, apartment hallways).

Also, some people hesitate to call 911 because they think it will “look bad.” But when the other person calls first, and you never call at all, that can shape the narrative from the start. Not always fair. Just real.

What To Do if Police Are On The Way (Or Already There)

This is not about being slick. It’s about not making it worse.

Don’t argue. Don’t match the intensity.
Don’t touch anyone. Not even a shoulder tap, not even trying to grab a phone, not even blocking a doorway. That’s how “minor” stuff becomes a DV allegation.
If safe, separate physically. Go to another room. Outside. Sit on the curb. Keep your hands visible.
Do not volunteer your phone. Do not “show them the texts” unless you’ve thought it through with counsel. You might think one message helps you, but then there are 40 messages that don’t.
If you’re arrested, stop talking. The ride to jail is not your chance to explain. The holding cell is not your chance to vent. Jail calls are not private.

Consequences That People Underestimate

Even if the charge looks “small” on paper, the DV label makes it heavier.

Some consequences can include:

Losing access to your home temporarily.
Parenting time restrictions and family court complications.
Immigration issues for non-citizens.
Job discipline, especially for licensed professions.
Firearm restrictions.
Required DV classes or treatment.
Probation with no contact conditions.
A record that shows a DV case, which can affect housing and background checks.

And the social fallout. Friends picking sides. Employers hearing rumors. It’s messy and fast.

What If You Are Falsely Accused Of Domestic Violence In Colorado?

False allegations do happen, often. Sometimes it’s anger. Sometimes it’s a tactical move in a custody case. Sometimes it’s just panic and then a backpedal. Sometimes it’s mutual chaos and one person gets labeled the aggressor.

If you’re falsely accused, the instinct is to bombard the other person with messages like “tell them the truth.” Don’t. That often creates the very evidence the state needs to keep the case going.

Better steps:

Write down your timeline privately, while it’s fresh.
Save texts, call logs, photos, and any relevant messages. Do not alter them.
Identify witnesses and cameras in the area immediately.
Get a lawyer early. Early is cheaper than late, and the strategy is different before charges solidify.

A Quick Reality Check About “Mandatory Arrest” and What it Means for You

Mandatory arrest laws were built around a real problem: historically, DV calls were treated as “just a family matter,” and violence kept escalating.

But the flip side is that once the system gets involved, it can feel like you lose control immediately. You might not be able to go home. You might not be able to text your partner. You might not be able to see your kids without a formal plan.

So the best thing you can do is understand the pressure points:

Police decide probable cause at the scene.
Arrest can happen even without cooperation from the alleged victim.
A protection order often follows right away.
Contact after the arrest can create new charges.
Evidence like 911 calls and body cam footage can carry the case even if someone recants.

Know your rights, then use them calmly

If you take nothing else from this, take this:

Be calm.
Don’t escalate.
Don’t try to “win the argument” in front of police.
Invoke your right to remain silent.
Ask for a lawyer.
Follow the protection order to the letter until and If, it’s modified in court.

If you’re in immediate danger, call 911. If you’ve been arrested or served with an order and you’re trying to figure out what to do next, talk to a Colorado attorney who works in DV defense and protection order matters. The early choices matter more than people realize.

FAQs (Frequently Asked Questions)

What does “mandatory arrest” mean in a Colorado domestic violence situation?

In Colorado, “mandatory arrest” means that if police have probable cause to believe domestic violence occurred, they are generally required by law to make an arrest. This doesn’t mean that anyone who calls the police will automatically be arrested; officers must have reasonable grounds – probable cause, based on evidence and observations – before making an arrest.

Who qualifies as being in a domestic violence relationship under Colorado law?

Colorado’s definition of domestic violence covers people in an “intimate relationship,” which includes married spouses, unmarried partners, current or former dating partners, people who share a child together, and those who live or used to live together in such a relationship. The law extends beyond physical violence to include threats, harassment, stalking, property damage, and other coercive acts within these relationships.

Can the alleged victim prevent an arrest from happening in a domestic violence case?

No. Even if the alleged victim asks the police not to arrest anyone, officers must follow the mandatory arrest rule if they believe there is probable cause that domestic violence occurred. The decision to arrest is based on evidence and officer judgment, not solely on the wishes of those involved.

Is it possible for both parties to be arrested in a Colorado domestic violence incident?

Yes, dual arrests can occur but Colorado law encourages officers to identify a primary aggressor and avoid dual arrests unless there is clear justification. Factors like who caused injuries, self-defense claims, prior history of violence, and control dynamics are considered when determining who should be arrested.

What rights do I have during a domestic violence police response in Colorado?

You have several important rights: you have the right to remain silent and request a lawyer; you can refuse consent to searches (though police may enter under certain exceptions); you have the right to legal representation early on; and you have the right to medical care if needed. Exercising these rights calmly and clearly can protect your interests during police interactions.

Why is understanding Colorado’s mandatory arrest rule important before facing a domestic violence situation?

Because a domestic violence arrest can impact your job, housing, gun rights, and custody arrangements, knowing how mandatory arrest works helps you prepare for what might happen during police involvement. Understanding probable cause standards and your rights ensures you respond appropriately and seek legal advice promptly if needed.

Why Experience Matters in Colorado Domestic Violence Cases

Mandatory arrest cases move fast, carry consequences that begin the moment handcuffs go on, and are governed by a dense web of statutes — protection orders, bond procedures, enhancement provisions, and firearm relinquishment rules — that most people have never had reason to learn. Over 40 years on both sides of the courtroom throughout the Denver metro area, including in the courts around the Lindsey-Flanigan Courthouse and the surrounding suburban jurisdictions, I have guided clients through every stage of this process: the advisement hearing, the fight to modify a restrictive protection order, and, where the facts support it, the challenge to the underlying charge itself.
