Does Montana's Prompt Pay Act override this construction contract's payment, retainage, or no-suspension terms?

Yes for some of those terms and no for others, and the line is not where it looks. For a written construction contract to build or improve real property in Montana the Act supplies DEFAULT timelines, two of which the contract may lengthen, and it voids a short list of clauses outright. Under § 28-2-2103(1)(b) a contractor's payment request is DEEMED approved 21 days after receipt unless the owner timely disapproves specific items in writing, and under (1)(f) an approved amount must be paid within 7 days of approval. Both of those subsections open “Except as provided in 28-2-2115”, and § 28-2-2115 is where the escape lives: an owner “may change the number of days to approve a contractor's payment request to later than 21 days”, and “may make payments later than 7 days after the date that the contractor's request for payment is approved”, in each case only if the contract “in a clear and conspicuous manner specifically provides” for the longer period AND a notice in substantially the form the section prints appears in clear and conspicuous type in the Information for Bidders section of the construction documents. So the 21 and the 7 are what the contract says if the contract is silent, not a floor. What the Act does NOT let the contract touch: a contractor must pay its subcontractor the full amount due within 7 days of receiving payment from the owner (§ 28-2-2103(2)), and no alternative-billing notice reaches that duty. Retainage is capped: “The maximum retainage applied to construction contracts subject to the provisions of this part may not exceed 5%” (§ 28-2-2110(1)), and a general contractor cannot withhold more from a subcontractor than the owner withheld from the general contractor. A contractor or subcontractor who is not paid may SUSPEND performance, and a contract clause saying otherwise is void: § 28-2-2116(2) makes it “against the public policy of this state” and “void and unenforceable” for a construction-contract provision to state “that a party to the contract may not suspend performance under the contract or terminate the contract if another party to the contract fails to make prompt payments under the contract as provided in 28-2-2103.” Two money consequences sit beside the timelines. A payment “delayed by more than 30 days from the date the payment is required by the contract to be made” carries interest at 1 1/2% a month on the unpaid balance (§ 28-2-2104(1)), although “[a]cceptance of the final payment releases any claim for interest on the payment” (§ 28-2-2104(3)), and the loser pays: in an action to enforce an obligation imposed by the Part, “the prevailing party is entitled to reasonable attorney fees and costs, both for trial and appeal” (§ 28-2-2105). Jem Contracting, Inc. v. Morrison-Maierle, Inc. invoked the no-suspension rule directly: the contractor “asserts this provision is void under § 28-2-2116(2), MCA, which provides” the no-suspension-voiding text quoted above, in a dispute over whether a contract clause barred the contractor from stopping work pending approval of a change order. JEM lost on other ground: “It is undisputed that JEM failed to follow the specific notification procedure in the Contract for differing subsurface conditions that was required for payment,” and the judgment against it was affirmed, so the case shows the section being argued rather than a clause being struck down under it.

The trap

Two separate void-clause rules live in this Part and are easy to conflate. § 28-2-2116(1) voids any Montana-construction-contract clause that picks ANOTHER STATE's law or requires dispute resolution to happen outside Montana, so a choice-of-law or venue clause routing a Montana construction dispute to another state is unenforceable regardless of what the parties agreed (the general, non-construction rule is different). § 28-2-2116(2) is the separate no-suspension voiding rule used above. Do not assume the Act reaches every real-property contract: its own definitions (§ 28-2-2101) limit “construction contract” to a WRITTEN agreement between an owner and a contractor to construct, improve, or provide construction management for an improvement to real property, and § 28-2-2107 takes out residential projects or improvements to real property intended for residential purposes with a total cost of less than $400,000. Suspension itself has its own procedural gate, § 28-2-2117: at least 7 calendar days' written notice before suspending or terminating, and a contractor may terminate only if the payment default is not cured within 30 days of suspension. That gate is one the contract may TIGHTEN but not loosen: the notice period applies “unless a shorter notice period is prescribed in the construction contract”, while § 28-2-2117(1)(d) provides that “[a] construction contract may not extend the time period for a contractor to suspend performance or terminate a construction contract under this subsection (1).” One more default worth knowing on a staged job: “[r]etainage must be released upon the final acceptance of each portion of work for which a separate price is stated in the construction contract” (§ 28-2-2110(3)), so a single release at project end is not what the statute contemplates.
