A Colorado lien waiver is a signed document in which a contractor, subcontractor, or supplier confirms receiving payment and gives up the right to file a mechanic’s lien for the amount that payment covers. Colorado governs these documents through the mechanic’s lien provisions in C.R.S. Article 22 and the construction payment rules in C.R.S. Article 46. Used correctly, the waiver keeps a property’s title clean as money moves down the payment chain. Used carelessly, it can strip a claimant of leverage before the check clears, or leave an owner exposed to liens they thought were cleared.
The Four Waiver Forms and When Each One Fits
Colorado projects use four standard forms, sorted along two questions: does the waiver cover a progress payment or the final payment, and does it take effect immediately or only once the payment clears?
- Conditional partial waiver. Covers a specific progress payment for work done to date, and becomes effective only when that payment actually clears the bank. If the check bounces, full lien rights survive. This is the everyday document on active projects.
- Unconditional partial waiver. Also covers a specific progress payment, but takes effect the moment it’s signed. Sign it only after confirming the funds are in the account.
- Conditional final waiver. Covers the entire remaining balance on the contract, contingent on the final payment clearing. Lien rights stay in place as leverage until the last dollar lands.
- Unconditional final waiver. Releases all remaining lien rights on the project permanently and immediately. Once signed, no lien can be placed on the property for any work under that contract.
The conditional versions protect the signer. The unconditional versions protect the payer. On a well-run job, conditional waivers move with each pay application, and unconditional waivers follow once the money is confirmed.
What a Colorado Lien Waiver Must Contain
Colorado does not prescribe a fill-in-the-blanks form. It does impose one requirement that trips people up. Under C.R.S. § 38-22-119, every lien waiver must include a statement from the person signing it confirming that all debts owed to third parties for the work or materials covered have been paid or will be paid on time.1Justia. Colorado Code 38-22-119 – Agreement to Waive – Effect A general contractor signing a waiver must represent that their subcontractors and suppliers have been or will be paid for the work the waiver covers. Leaving that statement out can undermine the waiver’s enforceability.
C.R.S. § 38-46-104 requires a payment recipient to provide an executed lien waiver for amounts actually paid whenever the contract or supply agreement calls for one.2Justia. Colorado Code 38-46-104 – Lien Waivers The statute ties the waiver to amounts “actually paid,” so asking for a waiver that exceeds what has changed hands goes beyond what the statute contemplates.
Beyond those statutory pieces, a usable waiver should identify the claimant and the payer, describe the property (a legal description or street address), state the payment amount matching the invoice, and give a through date for the work being released. If retainage is being withheld, list it separately so there’s no ambiguity about what is being waived and what isn’t. Colorado does not require notarization; a signed waiver is effective without one, though some owners and title companies ask for it as an extra precaution.
How the Exchange Should Work
The standard sequence protects both sides. The subcontractor submits an invoice with a signed conditional waiver. The owner or general contractor reviews the waiver against the invoice and releases payment. Once the funds clear, the subcontractor provides an unconditional waiver for the same period. The payer knows lien rights will be released; the payee doesn’t give them up until the money is in hand.
Many teams handle this through construction management software, with signed PDFs tied to specific pay applications. Paper still works if the document is exchanged at the same time as the check. Either way, both sides should keep copies of every signed waiver alongside records of when it was sent, received, and when the payment cleared.
Retainage Changes the Number on the Waiver
Retainage is the portion of each progress payment that the payer holds back as security until the project is finished. C.R.S. § 38-46-103 caps retainage at 5 percent of the price of work completed under the contract or subcontract, and the statute states that making a partial payment is not approval of the work and doesn’t waive the right to raise defects later.3FindLaw. Colorado Code 38-46-103
Retainage matters for waivers because the retained amount is excluded from a partial waiver. If a subcontractor’s invoice is $100,000 and the GC withholds $5,000, the partial waiver should cover $95,000. Lien rights on the retained $5,000 survive until it is actually paid and a final waiver signed. Mismatching those figures is one of the most common paperwork mistakes on Colorado projects.
Why a Waiver From the General Contractor Isn’t Enough
Section 38-22-119 also directs courts to give the mechanic’s lien statutes a “liberal construction,” and it limits waiver agreements to the parties who signed them.1Justia. Colorado Code 38-22-119 – Agreement to Waive – Effect A general contractor’s waiver does not strip lien rights from the subs and suppliers below them. That is where owners get surprised: a signed waiver from the GC can sit in the file while an unpaid second-tier sub records a lien anyway.
The third-party payment statement required by § 38-22-119(2) is meant to reduce that risk but doesn’t eliminate it. On projects with multiple subcontractors, owners routinely require waivers from every tier before releasing each draw. A waiver is also valid only to the extent of work already performed or materials already delivered when it’s signed. A blanket waiver reaching future, unperformed work runs into the statute’s protective framework and is unlikely to hold up.
Waiver vs. Release
These terms get used interchangeably and shouldn’t be. A lien waiver is exchanged before or at the time of payment and prevents a lien from being filed in the first place. A lien release removes a lien that has already been recorded. If a subcontractor files a mechanic’s lien and then gets paid, they sign a release (sometimes called a satisfaction of lien) that is recorded with the county clerk to clear the title. An owner going through a sale or refinance with a recorded lien needs a release, not just a waiver, to satisfy the title company.
The Deadlines Behind the Right You’re Waiving
Signing a waiver is easier to think about when you know what filing window it closes. Colorado’s mechanic’s lien filing deadlines under C.R.S. § 38-22-109 turn on the type of claimant:4Justia. Colorado Code 38-22-109 – Lien Statement
- Laborers paid by the day or piece who don’t furnish materials must file a lien statement within two months after the building or improvement is completed.
- Everyone else, including contractors, subcontractors, and suppliers, must file within four months after the day that claimant last performed labor or last furnished materials.
Before filing the lien statement with the county clerk, the claimant must serve a written notice of intent to file on both the property owner (or their agent) and the general contractor at least ten days ahead of filing. Skipping that notice can invalidate the lien. The statement itself must include the owner’s name, the claimant’s name, a property description sufficient to identify the parcel, and the amount owed, and it is filed with the county clerk and recorder in the county where the property sits.4Justia. Colorado Code 38-22-109 – Lien Statement Once recorded, the lien clouds title and blocks or complicates a sale or refinance until it’s resolved. That cloud is precisely what a properly sequenced waiver keeps from ever forming.
