Squatter’s rights in Colorado come from the state’s adverse possession statute, which lets a person who occupies land without permission eventually claim legal title, but only after 18 continuous years and only if they genuinely believed the property was theirs. In practice, almost no one meets that bar. The more immediate question for most property owners is how to remove someone who has moved in, and the answer depends on how long they have been there: a recent trespasser can usually be removed by police, while someone who has established residency has to be evicted through county court.
What Colorado’s Adverse Possession Law Actually Requires
Under Colorado Revised Statutes § 38-41-101, an occupant can gain title only by meeting five elements continuously for 18 years.1Justia. Colorado Code 38-41-101 – Limitation of Eighteen Years The possession must be:
- Hostile, meaning without the owner’s permission and against the owner’s rights.
- Actual, meaning the person is physically using the land the way an owner would, by maintaining it, building on it, or cultivating it.
- Open and notorious, meaning visible enough that an attentive owner would see it.
- Exclusive, meaning the occupant controls the land rather than sharing it with the public or the legal owner.
- Continuous, meaning uninterrupted for the full 18 years. Abandonment resets the clock.
Even when every element is satisfied, the occupant does not automatically own anything. They have to file a quiet title action and persuade a judge to transfer ownership. Until that order is entered, they have no legal interest in the property.
Colorado tightened these rules significantly in 2008. For any claim where ownership would vest on or after July 1, 2008, the occupant must also prove a good-faith belief that they were the actual owner, and that belief must have been reasonable.1Justia. Colorado Code 38-41-101 – Limitation of Eighteen Years A buyer whose deed turned out to describe the wrong parcel can meet this standard. A neighbor relying on a longstanding but inaccurate survey can meet it. Someone who knowingly moves onto land that belongs to someone else cannot.
The 2008 amendment also raised the burden of proof to clear and convincing evidence, a higher standard than the usual civil “more likely than not.”1Justia. Colorado Code 38-41-101 – Limitation of Eighteen Years Between the good-faith requirement and the heightened evidentiary standard, opportunistic claims by knowing trespassers almost never succeed in Colorado today.
The Seven-Year Color of Title Shortcut
There is one meaningful exception to the 18-year rule. If the occupant holds color of title, meaning a document that looks like it conveys ownership but is legally flawed, and the occupant pays all property taxes on the land for seven consecutive years, the required possession period drops to seven years.2Justia. Colorado Code 38-41-108 – Rights in Possession Seven Years – Color of Title and Payment of Taxes
Color of title usually comes from a defective deed, an improperly executed transfer, or a recording error. The document does not actually transfer ownership, but it gives the holder a reasonable basis for thinking it did. Every other element of adverse possession still has to be met; only the timeline changes. The occupant also carries the burden of producing both the flawed document and seven years of tax receipts.
This is why paying your property taxes matters even on vacant land you rarely visit. If someone else is paying them, they are building the paper trail for a shortened claim.
Trespasser or Squatter: Who Can Remove Them
Colorado treats recent trespassers and established occupants very differently, and that distinction decides whether you call the police or hire a lawyer.
If someone recently entered your property, say they broke into your vacant home last week, that is criminal trespass. Knowingly entering or remaining in someone else’s dwelling is first-degree criminal trespass under Colorado law.3Justia. Colorado Code 18-4-502 – First Degree Criminal Trespass Unlawfully entering or remaining on other types of premises is third-degree criminal trespass.4Justia. Colorado Code 18-4-504 – Third Degree Criminal Trespass Call law enforcement. The person can be arrested and removed without a court case.
The picture changes when someone has been in place for weeks or months, has moved belongings in, and has set up what looks like a residence. Officers often decline to remove that person and tell you it is a civil matter. At that point, you have to use the formal eviction process. The longer the person has been there, the more likely police will take that view.
Evicting a Squatter Through County Court
When law enforcement will not remove the occupant, Colorado requires you to file a forcible entry and detainer (FED) action in the county court for the county where the property sits.
The process starts with written notice. For residential property, Colorado generally requires 10 days’ written notice telling the occupant to leave.5Justia. Colorado Code 13-40-104 – Unlawful Detention If they do not vacate within that window, you file a complaint and summons with the court. The clerk sets a return date 7 to 14 days out, and the occupant must be served at least 7 days before the hearing.6Colorado Judicial Branch. Residential Evictions Service can be made by a process server, the sheriff, or any adult who is not a party. If personal service fails, the papers can be posted on the door and mailed.
At the hearing, if the occupant contests the case, the court sets a trial 7 to 10 days later. If the court rules for you, it enters a judgment for possession. After 48 hours you can request a writ of restitution, which authorizes the sheriff to physically remove the occupant. The sheriff cannot carry out that writ for at least 10 days after judgment, or 30 days if the occupant receives Social Security disability or similar benefits.7Colorado Judicial Branch. Understanding the Eviction Process
Even an uncontested eviction usually runs several weeks. A contested one takes longer. Plan for filing fees, service costs, and in many cases attorney fees, because getting the notice and service requirements right is what makes the judgment enforceable.
Why You Cannot Just Remove Them Yourself
Colorado Revised Statutes § 38-12-510 makes it unlawful to remove or exclude an occupant from a dwelling without going through the court process. Shutting off utilities, removing doors or windows, and changing locks are all specifically prohibited. An occupant who is locked out illegally can sue for actual damages plus statutory damages of three times the monthly rent or $5,000, whichever is higher, along with attorney fees and court costs.8FindLaw. Colorado Code 38-12-510 – Unlawful Removal or Exclusion A court can also order the person restored to the property. The result is that you end up poorer and still have the squatter inside. Self-help feels satisfying and almost always backfires.
How to Keep an Adverse Possession Claim From Ever Maturing
Adverse possession claims depend on the real owner being inattentive for close to two decades. A few consistent habits make them effectively impossible.
- Visit vacant or rural property a few times a year. Walk the boundaries. Look for new fences, cleared ground, gardens, or structures you did not build.
- Post no-trespassing signs. Visible signage undercuts any later claim that occupation was open and unchallenged, and it supports a criminal trespass report.
- If a neighbor is using part of your land with your knowledge, put the arrangement in writing. A simple license or use agreement destroys the hostile element because the use is now permitted. Most boundary-dispute claims collapse here when handled early.
- Pay property taxes on everything you own, even unused land. This blocks the seven-year color of title shortcut and leaves a continuous record of your ownership.
- Move quickly on unauthorized occupants. File a trespass report with police, and if eviction is needed, start it. Every week of delay helps the occupant’s continuous-possession clock.
Active ownership is the whole defense. Owners who stay engaged with their property, even in small ways, do not lose it to adverse possession.
