The brief
What a construction lender needs to know about Montana
Montana at a glance
Montana’s signature risk is the severable-improvements exception: even with a mortgage recorded first, a construction lien takes priority to the extent of any work that can be removed without harming the rest of the property — the lienholder can have that value determined and the improvement sold separately on foreclosure, bypassing your first position for removable assets. Liens otherwise relate back to the first visible change in the property, and retainage is capped at 5% on applicable private contracts over $400,000 (residential projects or improvements under $400,000 are exempt). The Prompt Payment Act deems an invoice approved 21 days after receipt unless the owner disapproves in writing, with payment due 7 days after. On residential 1–4 unit work subcontractors must serve a notice of right to claim a lien; on commercial and multi-family (5+ units) they’re exempt — so the large jobs arrive silent.
Lien law
Commercial work gives you no early warning.
Montana relation-back protects contractors well. Subs and suppliers on 1 to 4 unit residential work must send a notice of right to claim a lien; on commercial and multi-family of five units or more they are explicitly exempt. General contractors are exempt.
So on the commercial file, nobody is obliged to tell you they are on the job.
- Residential 1 to 4 units
- Notice of right to claim a lien within 20 days of first furnishing.
- Commercial and 5+ units
- Sub-tier claimants exempt from notice entirely.
Priority
The mortgage must be for this improvement.
Liens relate back to the commencement of work — the first visible change in the physical condition of the real estate. Recording before that gives you priority, but with a condition worth reading twice: the mortgage must have been taken to secure advances made for the purpose of paying for that particular improvement.
Montana also carries a severable improvements exception: if a claimant’s work can be removed without harming the rest of the property, it can be valued and sold separately, ahead of your mortgage, even where your recording was clean.
The Montana signature
The $400,000 line decides whether any of it applies.
The prompt payment act — and its 5% retainage cap — does not reach residential projects or improvements costing less than $400,000. Above that line, retainage tops out at 5% and a general contractor may not withhold a higher percentage from a sub than the owner is withholding from it.
- Residential under $400,000
- Outside the Act: no statutory cap or payment clock.
- Over $400,000
- 5% maximum, and a GC may not hold a higher percentage from a sub than the owner holds from the GC.
- Release per portion
- Retainage releases on final acceptance of each portion of work carrying a separate stated price.
Lien waivers
Advance waivers are void.
A construction contract may not require a contractor, sub, or supplier to waive lien rights before being paid. So the no-lien clause is unavailable here, and lenders should enforce a draw-by-draw exchange.
- Conditional · current draw
- Unconditional · previous draw
Deadlines
An invoice approves itself in twenty-one days.
On covered projects an invoice is deemed approved 21 days after receipt unless the owner disapproves in writing, and payment is due 7 days after approval. The prime pays subs within 7 days of receiving funds.
One Montana-specific note on the notice clock: where payment comes from a regulated lender secured by an encumbrance, the residential notice deadline extends from 20 to 45 days, except on owner-occupied homes.
Montana Lien Law Overview
Montana’s Construction Lien Law (MCA § 71-3-521 et. seq.) operates on a “relation-back” doctrine, making it a highly protective state for contractors. Liens attach to the real estate, including fee simple interests and leaseholds.
A critical distinction exists between residential and commercial projects regarding preliminary notices. Subcontractors and suppliers on residential projects (1-4 units) must provide a Notice of Right to Claim a Lien (MCA § 71-3-531). However, on commercial projects or multi-family properties (5+ units), subcontractors and suppliers are explicitly exempt from preliminary notice requirements. This creates a massive blind spot for commercial lenders regarding sub-tier payment failures
Mortgage Priority
Will a Montana Lien have priority over pre-existing mortgages or construction loans?
Generally, no, provided the construction mortgage is recorded before work commences — HOWEVER, there is a massive statutory exception for “severable improvements” that poses an extreme risk to lenders.
Montana follows a “relation-back” doctrine. A construction lien relates back to the “commencement of work,” which is defined as the date of the first visible change in the physical condition of the real estate (MCA § 71-3-522(1)).
- Establishing General Priority: Under MCA § 71-3-542(4), a construction mortgage recorded before the commencement of work has priority over construction liens, provided the mortgage was taken to secure advances made for the purpose of paying for the particular real estate improvement. To secure this statutory priority, it is a critical best practice that the lender ensures the mortgage is recorded before a single shovel of dirt is moved.
- EXTREME LENDER RISK: The “Severable Improvements” Exception: Under MCA § 71-3-542(3), a construction lien has priority, to the extent of the value of the work or improvement that is severable, over an interest, lien, mortgage, or encumbrance that is filed before the construction lien attaches. If the work or improvement may be removed without harm to the rest of the real property, the lienholder may have the value determined and the improvement sold separately on foreclosure. This can bypass the lender’s first-position mortgage for removable assets.
- Loss of Priority: If visible work commences before the mortgage is recorded, all subsequent construction liens relate back to that commencement date, leapfrogging the construction loan and taking superior priority over the lender’s security interest.
Retainage Overview
Montana strictly caps private retainage through its Prompt Payment Act. Note that the provisions of this Act (including retainage caps) do not apply to residential projects or improvements with a total cost of less than $400,000 (MCA § 28-2-2107).
- Multi-Family, Commercial, & Applicable Residential Limits: Under MCA § 28-2-2110, the maximum retainage applied to any applicable private construction contract may not exceed 5% if the contractor is performing by the terms of the contract. Furthermore, a general contractor may not withhold a higher percentage from a subcontractor than the owner is withholding from the general contractor.
- Release Timeline: Retainage must be released upon the final acceptance of each portion of work for which a separate price is stated in the construction contract (MCA § 28-2-2110(3)).
- Lender Best Practice: Lenders should ensure their Loan Agreements, internal budgets, and draw administration protocols are configured to cap retainage at a strict 5% on applicable projects. Attempting to withhold a standard 10% on a Montana project that falls under the Act violates state law, exposing the owner to 1.5% monthly interest penalties.
Prompt Payment Act
The Montana Prompt Payment Act (MCA § 28-2-2101 et seq.) applies to private construction contracts, including Multi-Family and Commercial properties. Exception: The Act does not apply to residential projects or improvements intended for residential purposes with a total cost of less than $400,000 (MCA § 28-2-2107).
- Owner to General Contractor: For applicable projects, the property owner must pay the general contractor within 7 days after approving an invoice (MCA § 28-2-2103(1)(f)). An invoice is considered approved 21 days after receipt unless the owner provides a written statement of disapproval (MCA § 28-2-2103(1)(b)).
- General Contractor to Subcontractor: The general contractor must pay subcontractors within 7 days of receiving payment from the owner (MCA § 28-2-2103(2)(a)).
- Penalties: Late payments accrue interest at a strict statutory rate of 1.5% per month (18% annually) (MCA § 28-2-2104).
- Lender Impact: The 21-day/7-day logic creates massive operational pressure. Lenders handling Montana loans should ensure their internal processes are efficient to fund within the window and avoid interest penalties for the borrower.
Title Practices
Under Montana law, title companies are not mandated to administer construction loan disbursements; there is no statutory construction escrow mandate. Therefore, lender-managed disbursements (or third-party draw administration) represent the standard industry practice.
Maintaining first lien priority in Montana requires vigilant oversight of both the physical job site and public records. Because Montana utilizes a “relation-back” doctrine where liens attach at the commencement of physical work, lenders should proactively monitor the title prior to every single disbursement.
Lenders have three primary options to achieve this:
- Lien monitoring subscription services: Tracks public recordings.
- Title updates/date-downs: Checks public records for newly filed liens but does not provide active insurance coverage against hidden risks.
- Title endorsements: (ALTA 32 and ALTA 33), which provide actual insurance against mechanics liens.
Lender Best Practice: It is highly recommended that lenders utilize ALTA 32 (Loss of Priority) and ALTA 33 (Disbursement) endorsements. Montana title law presents an extreme risk to lenders through its “Severable Improvements” loophole. Because suppliers can repossess installed materials regardless of when the mortgage was recorded, securing an ALTA title endorsement is the only method to actively shift this severe statutory risk from the lender to the title insurer. Regardless of the chosen method, instructing the title company or draw administrator to identify and clear any encumbrances discovered during the draw administration process is a crucial step before releasing funds.
Lien Waivers
Lien Waiver Summary
Because Montana does not provide statutory lien waiver forms, their enforceability is governed by standard contract law and public policy principles.
- Advance Waivers Prohibited: Montana strictly prohibits advance lien waivers. A construction contract may not contain provisions requiring a contractor, subcontractor, or supplier to waive the right to claim a construction lien before they have actually been paid for the labor or materials furnished (MCA § 28-2-723).
- Lender Best Practice: Because advance “no-lien” clauses are void, lenders should enforce a strict draw-by-draw exchange using heavily vetted custom forms. Lenders should exclusively collect Conditional Waivers for current draw requests (expressly conditioned on the receipt and clearance of funds) and Unconditional Waivers for prior draws to definitively prove payment reached the claimant.
Statutory Lien Forms
Montana mandates strict statutory language and formatting for the Notice of Right to Claim a Lien (MCA § 71-3-532) and the Construction Lien itself (MCA § 71-3-536). However, the state does not prescribe statutory templates for lien waivers.
Lien Waiver Notarization
Montana law does not require lien waivers to be notarized to be considered legally valid and effective. A signed, written agreement is sufficient. (Note: The actual Construction Lien recorded with the county clerk must be verified by a notarized affidavit (MCA § 71-3-536(3)), but standard progress waivers do not).
Notices
Notice of Commencement (or similar like event)
Montana does not utilize a recorded Notice of Commencement for private construction projects to establish project start dates. Priority is strictly determined by the actual, physical commencement of work on the site.
Preliminary Lien Notifications
- Who Must Send: Any subcontractor, material supplier, or equipment lessor who does not have a direct contract with the property owner. General contractors are explicitly exempt from preliminary notice requirements.
- Residential (1-4 Units): Claimants must send a Notice of Right to Claim a Lien to the owner within 20 days of first furnishing labor or materials (MCA § 71-3-531(2)).
- Regulated Lender Exception: When payment is made from funds provided by a regulated lender and secured by an encumbrance, the deadline is extended to 45 days of first furnishing. However, this exception strictly excludes owner-occupied residences (MCA § 71-3-531(4)). Therefore, owner-occupied projects are subject to the standard 20-day rule, while non-owner-occupied 1-4 unit projects (like spec or rental homes) funded by a regulated lender benefit from the 45-day extension.
- Filing Requirement: In addition to serving the owner, the notice must be filed with the county clerk within 5 business days of serving the owner (MCA § 71-3-531(6)(a)).
- Multi-Family (5+ Units) & Commercial: Subcontractors and suppliers are exempt from sending a Notice of Right to Claim a Lien on these projects (MCA § 71-3-531(1)(b) & (d)).
- Implications of Failure: If notice is not given within the 20-day (or 45-day) window, the lien is restricted only to the value of labor or materials provided in the 20 days (or 45 days) immediately preceding the date the notice is finally given.
Notice of Completion (or similar like event)
- Recognized by State? Yes.
- When Must it be Filed: The owner may record a Notice of Completion with the county clerk and recorder at the end of the project (MCA § 71-3-533).
- Effect: Filing this document explicitly solidifies the deadline for claimants to file a Construction Lien. By statute, claimants must file their lien no later than 90 days after the claimant’s final furnishing of labor/materials, or 90 days after the date the owner records a Notice of Completion — whichever occurs first (MCA § 71-3-535). This establishes a hard cutoff date for potential lien exposure.
Additional State-Specific Notices
- Release of Notice of Right to Claim a Lien: Under MCA § 71-3-538, if a subcontractor filed a preliminary Notice of Right to Claim a Lien and is subsequently paid in full, the property owner may submit a request demanding the claimant release the notice. The claimant must file a release with the county clerk within five (5) business days of the request (MCA § 71-3-538). Failure to do so subjects the claimant to liability for any damages suffered by the owner, plus costs and attorney fees.
Document References
- Notice of Right to Claim a Lien (Preliminary Notice):
- Use & Purpose: A statutory notice strictly required (MCA § 71-3-531) from subcontractors, material suppliers, and any party who does not have a direct contract with the property owner on residential projects. It must be sent to the owner and filed with the county clerk (MCA § 71-3-531).
- Benefit to Lender/Owner: Identifies lower-tier participants and traps funds. This gives the draw administrator clear visibility into exactly who needs to be paid or supply a waiver to avoid a lien.
- Implications if Not Used: If a required claimant fails to provide this notice within the statutory timeframe, their lien rights are strictly limited to the services or materials provided after the late notice is finally given.
- Statute Citation: MCA § 71-3-531.
- Construction Lien:
- Use & Purpose: The formal, statutory document filed with the county clerk and recorder to perfect the encumbrance against the property.
- Benefit to Lender/Owner: Formally bounds the claim amount and clearly identifies the claimant, allowing the lender to withhold funds, enforce a joint check, or demand a bond.
- Implications if Not Used: If not filed within 90 days of the claimant’s last date of furnishing (or 90 days after a Notice of Completion is recorded), the claimant’s lien rights are completely extinguished.
- Statute Citation: MCA § 71-3-535.
- Notice of Completion:
- Use & Purpose: A document recorded by the property owner (or their agent) upon the completion of the project.
- Benefit to Lender/Owner: Solidifies the project completion date and explicitly triggers the 90-day countdown for all claimants to file a Construction Lien.
- Implications if Not Used: If not recorded, the 90-day lien filing window remains individually tied to each claimant’s absolute last day of work, dangerously extending the “tail-risk” timeline for the lender.
- Statute Citation: MCA § 71-3-533.
- Release of Notice of Right to Claim Lien:
- Use & Purpose: A statutory document filed with the county clerk to officially remove a previously recorded Notice of Right to Claim a Lien.
- Benefit to Lender/Owner: Clears the public record of preliminary notices once a subcontractor has been paid, ensuring a clean title before the next draw.
- Implications if Not Used: If a claimant has been paid and the owner issues a request for a release, the claimant is liable for damages if they fail to file this release within five business days of the request.
- Statute Citation: MCA § 71-3-538.
Contractor Licensing & Bond Requirements
Montana does not issue a traditional “General Contractor” license at the state level, but it maintains strict registration requirements.
- Contractor Registration: Any construction contractor or subcontractor with employees must register with the Montana Department of Labor & Industry (DLI) (MCA § 39-9-201).
- Independent Contractors: Contractors working without employees must obtain an Independent Contractor Exemption Certificate (ICEC) from the DLI (MCA § 39-71-417).
- Specialty Trades: Electricians and plumbers are strictly required to hold state-issued professional licenses to perform work in Montana (MCA § 37-68-301; MCA § 37-69-301).
- Surety Bond: Montana does not have a statewide surety bond requirement for private commercial or residential general contractors.
- License Lookup: Lenders should verify the GC’s registration status prior to loan closing via the official portal: Montana Department of Labor & Industry Contractor Search.
Frequently Asked Questions
We are funding a large multi-family development (10 units). Why haven’t we received any preliminary notices from the subcontractors?
In Montana, there is a significant statutory “blind spot” for lenders on larger projects. Under MCA § 71-3-531(1)(b) and (d), subcontractors and suppliers on commercial projects or multi-family properties with five or more units are explicitly exempt from preliminary notice requirements. Unlike residential projects of 1-4 units where a Notice of Right to Claim a Lien is required under MCA § 71-3-531(2), you will likely have zero statutory visibility into the sub-tier participants on a commercial job site. Because you won’t receive these “warning shots” identifying who is on the job, your risk of a surprise lien is substantially higher. As a best practice, you should not rely on the absence of notices as a sign of a “clean” project. Instead, insist on ALTA 32 and 33 title endorsements to shift the risk of these hidden liens to the title insurer, and require your general contractor to provide a full sub-payee list with every draw request to ensure funds are reaching every tier.
If our construction mortgage was recorded before any work began, are we fully protected against all subsequent lien claims?
While recording your mortgage before the “commencement of work” generally establishes priority under MCA § 71-3-542(4), Montana law contains a high-risk exception known as the “Severable Improvements” doctrine. According to MCA § 71-3-542(3), a construction lien takes priority over a pre-existing mortgage to the extent of the value of any work or improvement that is “severable” — meaning it can be removed without harming the rest of the real property. This means a supplier of removable assets could potentially leapfrog your first-position mortgage, have the value of those specific improvements determined, and sell them separately in a foreclosure. To mitigate this, your next step should be to ensure your title policy specifically covers this loophole. Relying on a standard date-down is insufficient; only an ALTA 32 (Loss of Priority) endorsement provides the affirmative insurance necessary to protect against the statutory priority granted to these severable improvements.
Our standard policy is to hold 10% retainage on all construction loans. Does this meet Montana’s compliance standards for a $1M warehouse project?
No, following a standard 10% retainage policy on this project would be a direct violation of the Montana Prompt Payment Act. For private construction contracts exceeding $400,000 (excluding 1-4 unit residential), MCA § 28-2-2110 strictly caps retainage at 5%. Furthermore, MCA § 28-2-2110(3) requires that retainage be released upon the final acceptance of each portion of work for which a separate price is stated in the contract. If you or the owner attempt to withhold 10%, you expose the project to significant financial penalties. Under MCA § 28-2-2104, late payments — including improperly withheld retainage — accrue a strict statutory interest rate of 1.5% per month (18% annually). Your best practice is to audit your loan agreements and budget templates specifically for Montana commercial projects to ensure retainage is capped at 5% and that your draw administration workflow accounts for the “incremental release” of these funds.
The project is finished, but we are worried about “tail risk” from unknown suppliers. How do we force a hard deadline for lien filings?
To minimize the period during which a lien can be filed, you should ensure the owner records a Notice of Completion pursuant to MCA § 71-3-533. Without this recorded notice, the window for a claimant to file a construction lien remains open for 90 days after their individual “final furnishing” of labor or materials. This creates an inconsistent and dangerously extended timeline for the lender, as different subs finish at different times. By recording the Notice of Completion, you trigger a definitive 90-day countdown that applies to all potential claimants. Per MCA § 71-3-535, the deadline to file a lien becomes 90 days after the claimant’s last work or 90 days after the Notice of Completion is recorded — whichever occurs first. As a best practice, make the recording of this notice a mandatory condition for your final “milestone” disbursement to ensure the 90-day clock starts ticking for every participant on the project simultaneously.
