Colorado lien waivers

Colorado does not prescribe statutory waiver forms, so AIA-style language is enforceable. The state compensates for that flexibility by requiring strict compliance with a Notice of Intent to File a Lien Statement, which has to be served on the owner and the prime contractor at least 10 days before the lien is recorded under C.R.S. § 38-22-109(3). Missing the Notice of Intent voids the lien outright. Filing windows are 4 months from last labor or materials for most claimants and 2 months for laborers and equipment lessors, and the trust fund obligations in § 38-22-127 add a parallel layer of personal liability for contractors who commingle progress payments.

The statute

Colorado mechanics-lien practice is codified at C.R.S. § 38-22-101 et seq. Section 38-22-101 grants a lien to anyone furnishing labor, materials, or services for the construction, alteration, or repair of any structure on real property. The chapter covers private projects throughout the state, with separate provisions in Title 38 for public works. For a residential builder, the operative sections are § 38-22-109 (filing and the Notice of Intent), § 38-22-110 (action to enforce and lis pendens), § 38-22-126 (the disbursement statute applicable to construction loans), and § 38-22-127 (the trust fund obligations).

Compared to California or Texas, Colorado’s waiver regime is permissive on form and demanding on procedure. There are no statutory waiver forms to memorize, but the procedural machinery around the Notice of Intent, lis pendens recording, and trust fund accounting is unforgiving and is the source of most lost lien rights in the state.

No statutory waiver forms

Colorado does not prescribe a statutory waiver form. Any plainly worded waiver is enforceable as long as it clearly identifies the project, the claimant, the amount and period covered, and the payment that triggers the release. AIA G706 and G707 are commonly used and are enforceable in their unmodified form. Generic conditional and unconditional progress waivers work. Lender and title-company forms work. As in any state without statutory text, the discipline question is about cycle, not form: are the conditional waivers issued with each invoice and are the unconditional waivers collected after each payment clears.

The 10-day Notice of Intent

Section 38-22-109(3) is the procedural requirement that catches most builders and subs the first time they run a Colorado project. Before recording a mechanics lien, the claimant has to serve a Notice of Intent to File a Lien Statement on both the owner of the property and the prime contractor at least 10 days before the lien is recorded. The notice has to include a legal description of the property, the amount claimed, and the basis for the claim.

Service has to be by personal service or by certified mail, return receipt requested. The 10-day clock runs from the date of service, not the date the notice is sent. A notice mailed on day 5 and received on day 8 does not satisfy the requirement if the lien is recorded on day 14, because only six days will have elapsed since service. The cleanest practice is to send the notice by certified mail, wait for the return receipt, and then count 10 calendar days from the receipt date before recording.

Missing the Notice of Intent voids the lien. There is no after-the-fact cure. A claimant who records a lien without first serving the Notice of Intent has not perfected a valid lien and the recording can be challenged successfully on that basis alone. The Colorado courts have been consistent in enforcing the notice requirement strictly, and a defectively noticed lien is not the kind of problem that can be argued around with substantial-compliance arguments.

Filing deadlines

Section 38-22-109 sets two different filing windows depending on the type of claimant. The general window for most claimants (subs, suppliers, design professionals, the prime contractor) is four months after the date the claimant last furnished labor or materials on the project. Laborers and equipment lessors have a shorter two-month window. The distinction matters because a labor-only sub working alongside a materials sub on the same project can have lien rights expire two months earlier than the materials sub.

Section 38-22-110 requires the claimant to commence an action to enforce the lien within six months of the project being finished or the date the claimant last furnished labor or materials, whichever is earlier. A claimant who files the lien on time but lets the six-month enforcement window slip loses the lien regardless of the merits of the underlying claim.

Lis pendens recording extends enforcement

The enforcement deadline can be functionally extended by recording a notice of lis pendens within the six-month window. Section 38-22-110 requires the claimant to file the foreclosure action and record a lis pendens to preserve the lien priority pending the litigation. A lien that was timely filed but never had a lis pendens recorded inside the enforcement window lapses by operation of law, even if the claimant filed the lawsuit on time.

The two-step (file the action and record the lis pendens) often surprises out-of-state counsel because most jurisdictions treat the filing of the complaint as sufficient to preserve lien priority. Colorado treats the recording of the lis pendens as the act that puts the world on notice of the pending dispute, and without a recorded lis pendens a subsequent purchaser or lender can take free of the lien. For a residential builder dealing with a contested closeout, the practical rule is to file the foreclosure action and record the lis pendens on the same day, well inside the six-month window.

Trust fund obligations

Section 38-22-127 imposes a trust fund obligation on contractors and subs who receive progress payments from the owner or upstream contractor. Funds received for work performed by downstream parties are held in trust for those downstream parties until the downstream parties have been paid. Commingling the trust funds with general operating funds, or using the trust funds to pay obligations unrelated to the project from which the funds came, is a violation of the statute.

The consequences are both civil and criminal. Civilly, an aggrieved downstream party can sue the contractor or sub personally for breach of the trust, and the personal liability of the responsible officers and directors of a corporate contractor is on the table. Criminally, § 18-4-401 treats misuse of trust funds as theft, with the threshold for felony treatment depending on the amount misappropriated. This is the rule that makes a Colorado contractor unable to rob Peter to pay Paul across projects: each project’s funds belong to that project’s subs and suppliers until they are paid.

For a residential builder, the operating practice that satisfies § 38-22-127 is straightforward. Each project has its own designated bank account or sub-ledger, draw funds are deposited into that account, sub and supplier payments come out of that account, and funds are not transferred between projects. Builders who treat the construction account as a single pool risk both the civil exposure and the personal criminal exposure if a downstream party files a complaint.

The disbursement statute

Section 38-22-126 governs the disbursement of construction loan proceeds and applies to projects financed with a construction loan. The statute sets out a specific procedure that lenders and disbursing agents have to follow when releasing draw funds, including verification of the work in place and lien waiver collection from downstream claimants. Lenders who follow the procedure maintain priority for the construction loan over subsequent mechanics liens. Lenders who deviate from the procedure can find their loan subordinated to a mechanics lien even if the loan was recorded first.

For the builder, the disbursement statute is mostly a lender-side obligation, but it shapes the documentation the lender will demand at each draw. Expect the lender or its disbursing agent to ask for conditional progress waivers with each draw request, unconditional progress waivers covering prior periods, and an updated sworn statement of subs and suppliers. A draw package that does not include the waivers in the form the disbursing agent expects will be held until the gap is closed, regardless of how clean the work in place is.

Owner-occupied residential

Colorado does not have a sweeping owner-occupied residential carve-out the way some states (notably Arizona and Texas) do. Owner-occupied homes are subject to the same lien regime as other private projects. The Notice of Intent applies, the filing windows apply, and the trust fund obligations apply.

That said, the trust fund and Notice of Intent rules give owner-occupiers practical leverage that they would not have in a state with looser procedural machinery. An owner facing a threatened lien can demand documentation that the Notice of Intent was properly served and can ask the contractor for a trust-fund accounting before paying further. The procedural strictness cuts both ways: it protects sub lien rights when the procedures are followed, and it gives owners grounds to challenge liens when the procedures are skipped.

A clean monthly draw cycle

On a typical Colorado custom home, the clean cycle starts with a project-level bank account or sub-ledger that segregates draw proceeds for trust fund compliance. Each month, subs submit invoices with conditional progress waivers identifying the project, claimant, customer, payer, amount, and period covered. The builder assembles the draw package with the invoices and conditional waivers plus prior-period unconditional waivers, and the lender (following the § 38-22-126 disbursement procedure) funds the draw into the project account.

The builder pays subs from the project account, requests unconditional progress waivers within 48 hours of payment, and stores the returned waivers in the project file. A separate lien-tracking calendar runs in parallel: any sub unpaid more than 30 days past invoice gets a status check, and the calendar flags day 60 from each sub’s last work as the trigger to evaluate whether a Notice of Intent should be prepared. If the sub still has not been paid by day 75, the Notice of Intent goes out by certified mail so the 10-day clock runs before the 4-month or 2-month filing window closes.

The lien-tracking discipline is what separates Colorado from looser states. The combination of two different filing windows (4 months and 2 months), the mandatory Notice of Intent, and the lis pendens enforcement requirement means a single passive month from a sub can move the lien rights from intact to gone. Builders who run a calendar against last-work dates for every sub on the project rarely have a problem. Builders who try to track lien windows in a spreadsheet by memory often find a sub has lost rights without anyone noticing until the closeout.

Common pitfalls

The most common reason Colorado liens are voided is skipping the Notice of Intent. A sub or supplier records a lien within the 4-month window, the lien is challenged in court, and the claimant cannot produce evidence of timely Notice of Intent service. The lien is invalidated, the foreclosure action goes nowhere, and the sub is left with an unsecured contract claim. The fix is treating the Notice of Intent as a non-negotiable step in the lien process, always served by certified mail with return receipt, and never recording a lien fewer than 10 days after the receipt date.

The second pitfall is missing the distinction between the 4-month general filing window and the 2-month window for laborers and equipment lessors. A contractor who employs labor-only subs alongside materials subs on the same project has two different lien clocks running, and the labor-side clock runs out first. Builders who treat the project as a single 4-month window discover late that some claimants had a shorter window and have already lost rights.

The third pitfall is commingling trust funds. A contractor who pays Project A’s subs from Project B’s draw is in violation of § 38-22-127 even if the work eventually gets paid for and nobody complains. If a downstream party on Project B does eventually go unpaid, the commingling becomes the basis for a personal liability claim against the responsible officers and a potential criminal complaint. The civil exposure alone is reason enough to run separate project accounts; the criminal exposure makes it a non-starter.

The fourth pitfall is letting the lis pendens recording slip after filing the foreclosure complaint. Counsel familiar with other states sometimes treats the complaint as the operative act and lets the lis pendens recording follow when it is convenient. In Colorado, the lis pendens recording is the act that preserves lien priority, and a complaint without a timely-recorded lis pendens leaves the lien lapsed by operation of law. The discipline is to file the complaint and record the lis pendens as a single coordinated step.
