A Colorado mechanics lien is a legal claim that secures your right to payment by attaching to the property where you worked. Under C.R.S. § 38-22-109, the law sets firm time limits on when a claimant can file. Miss one, and your right to collect is gone entirely. Baker Law Group, PLLC works with contractors, subcontractors, and suppliers across Colorado to protect their right to payment. Our team ensures every mechanics lien deadline is met before the clock runs out.
How Long Do You Have to File a Mechanics Lien in Colorado?
The filling window depends on what you contributed to the project. Colorado mechanics lien law establishes two separate deadlines based on the type of work performed.
Labor only (day or piece work, without furnishing materials)
You must record your lien within two months after project completion. This deadline follows completion of the improvement, not your personal last day on site.
Labor and materials, or materials only
You must record your lien within four months after the last date you furnished labor or materials to the project.
Both windows run from specific statutory events, not from the date a payment dispute began. A subcontractor who stopped work weeks ago and has not received payment may have far less time remaining than they realize.
The Colorado Mechanics Lien Process: Three Steps You Cannot Skip
The Colorado mechanics lien timeline involves three required steps. Each must occur in order and within the required timeframe. Missing any one of them ends the claim entirely.
Step 1: Serve the Colorado Notice of Intent to Lien
Before filing anything with the county, you must serve a notice of intent to lien on the property owner. Colorado law requires you to deliver this notice at least 10 days before you file the lien.
The notice of intent to lien must state the unpaid balance and signal that you will record a lien if payment does not follow. This step is not optional. It is a statutory prerequisite. It also gives the property owner a final opportunity to resolve the dispute before a lien goes on record. In many cases, this notice alone produces payment without any further legal action.
You must properly prepare the notice and deliver it to the correct party. Errors in the recipient, the content, or the delivery method can invalidate the entire lien claim, even if you followed every other step correctly.
Step 2: File the Lien with the County Recorder
After the 10-day notice period passes, you must file the lien with the county recorder’s office where the property is located. This filing must occur before the two-month or four-month deadline expires, whichever applies to your situation.
Filing in the correct county is as important as filing on time. A lien recorded in the wrong jurisdiction does not protect your claim. If you have questions about what it costs to file a mechanics lien in Colorado before you proceed, reviewing those figures in advance helps you plan accordingly.
Step 3: Enforce the Lien Before the Window Closes
Filing the lien is not the final step. Once recorded, you have six months from the last date labor or materials were provided, or six months from project completion, whichever is later, to enforce the lien in court. Enforcement means initiating a foreclosure action. If you do not file that action within six months, the lien expires.
Claimants miss this enforcement window more often than any other part of the Colorado mechanics lien process. Contractors who record correctly but fail to follow through on enforcement lose their claim just as surely as those who miss the initial filing deadline.
How Long Is a Colorado Mechanics Lien Good For?
A recorded Colorado mechanics lien is valid for six months from the date it is filed. If no court action is initiated to enforce the lien within that six-month period, it expires and loses all legal force. A lapsed lien cannot be reinstated.
This is separate from the recording deadline. A contractor may file well within the two- or four-month window and still forfeit the claim by failing to act before the enforcement period closes. “Does a mechanics lien expire?” and “how long is a mechanics lien good for?” both have the same direct answer in Colorado: six months from the recording date, with no exception.
If you have recorded a mechanics lien in Colorado and are approaching the six-month mark without payment or resolution, that window requires immediate attention.
What Happens If You Miss a Colorado Mechanics Lien Deadline?
Missing any stage of the Colorado mechanics lien timeline results in forfeiture of your lien rights. Colorado law provides no grace period. A lien filed one day late is unenforceable. A notice sent to the wrong party does not count. Failure to enforce within six months voids the lien entirely.
Once lien rights are lost, the remaining paths to recovering unpaid amounts are breach of contract claims and other civil actions. Those routes are more time-consuming, more costly, and provide none of the property-security protections that a mechanics lien carries.
On an unpaid construction project, the first question to answer is how long you have to file a mechanics lien in Colorado. The longer a payment dispute sits unresolved, the shorter the window becomes. In Colorado, that window does not reset.
Lien Waivers: Review Before You Sign
During the payment process, property owners or general contractors sometimes request lien waivers or releases as a condition of payment. A lien waiver surrenders your right to file a lien, so timing matters.
Confirm that payment has actually cleared before signing any waiver or release. Signing too early eliminates your lien rights before the money has arrived, leaving no statutory recourse if payment does not follow. Once payment is confirmed and the dispute is resolved, you will also need to understand how to release the lien in Colorado to clear the record on the property. If you are uncertain what a waiver means for your rights, an attorney can review the document before you sign.

Frequently Asked Questions
How long does a subcontractor have to file a mechanics lien in Colorado?
A subcontractor who furnishes both labor and materials has four months from the last date those items were provided to record a mechanics lien in Colorado. A subcontractor performing labor only, without furnishing materials, must record within two months of project completion.
Does a mechanics lien expire in Colorado?
Yes. A recorded Colorado mechanics lien expires six months after it is filed if no court action is initiated to enforce it. The enforcement window runs from the last date labor or materials were furnished, or from project completion, whichever is later. A lien that expires through inaction cannot be reinstated, and the right to payment through the lien process is permanently lost.
What must a Colorado notice of intent to lien include?
The notice of intent to lien must identify the unpaid balance and state the intent to record a lien if payment is not made. It must be delivered to the property owner and served at least 10 days before the lien is filed. Errors in the recipient, the content, or the delivery method can invalidate the entire lien claim, even when the rest of the process is handled correctly.
Can you file a mechanics lien in Colorado if you only provided labor?
Yes. Colorado law allows laborers performing day or piece work to file a mechanics lien. The filing window is shorter: two months from project completion rather than the four-month window that applies to those who also furnished materials. The same three-step process applies, including the notice of intent to lien and the six-month enforcement deadline after recording.
What is the enforcement deadline for a Colorado mechanics lien?
After recording a mechanics lien in Colorado, you have six months to file a court action to enforce it. Enforcement means initiating a foreclosure proceeding against the property. If that action is not filed within six months, the lien expires and becomes legally unenforceable regardless of whether the underlying debt is valid.
What happens if I miss the mechanics lien filing deadline in Colorado?
Missing the recording deadline, failing to serve the required notice of intent to lien, or neglecting to enforce within six months all carry the same consequence: you lose your statutory right to payment through the lien process. Colorado law provides no grace period. Once the deadline passes, the remaining paths to recovery are breach of contract or other civil claims, which carry different procedural requirements and do not provide the property-security protections a mechanics lien does.
