Mechanic's Lien Waiver Form and Advance-Waiver Rules in Montana
At a glance
| Governing law and project scope | Montana Code Annotated Title 71, ch. 3, part 5 (Construction Liens, §§ 71-3-521 to 71-3-563). This part is the exclusive means by which a nonconsensual construction lien arises for a person furnishing services or materials under a 'real estate improvement contract' (§ 71-3-521). The advance-waiver ban is in the contracts title, MCA § 28-2-723, and expressly covers construction-lien and payment-bond claims. |
|---|---|
| Advance or prospective waiver | Void. A construction contract 'may not contain provisions requiring a contractor, subcontractor, or material supplier to waive the right to a construction lien or a right to a claim against a payment bond before' that party 'has been paid for the labor, materials, or both … furnished' (MCA § 28-2-723). The statutory prohibition applies to a pre-payment waiver required by the construction contract; the section does not state a separate rule for a voluntary waiver or one requested after payment. |
| Statutory form requirement | None. Neither part 5 nor § 28-2-723 prescribes a waiver form. Section 71-3-532 prescribes the separate notice of the right to claim a lien, and § 71-3-536 supplies a form for the recorded lien notice, but the part-5 section index contains no conditional/unconditional or progress/final waiver form, warning, or field list. |
| Waiver types and payment stage | No statutory conditional/unconditional or progress/final waiver labels and no statutory partial/through-date release. The statutory dividing line is timing, not form: a contract cannot require a waiver 'before' the claimant is paid (§ 28-2-723). Any conditional structure exists only if the parties draft it. |
| Payment and effectiveness | Section 28-2-723 keys the ban on a required waiver to whether the claimant 'has been paid'; a construction-contract provision demanding a waiver before payment is void. The section supplies no cleared-check, actual-receipt, evidence-of-payment, or failed-payment rule for a later waiver. |
| Required contents, exceptions, and through date | None prescribed. Neither § 28-2-723 nor part 5 lists required claimant, owner, amount, or through-date fields for a waiver, or any statutory carve-out for retainage, extras, change orders, later work, or other reservations. |
| Rights released and reserved | Section 28-2-723 protects two rights from a construction-contract provision requiring their waiver before payment: the construction lien under part 5 and 'a right to a claim against a payment bond.' The section does not define the reach of a waiver requested after payment or create a separate stop-notice right. |
| Signature, authority, notary, and format | Not specified for a pre-recording waiver. Neither § 28-2-723 nor part 5 prescribes signature, authority, notarization, warning, electronic-form, or attachment requirements for such a waiver. Section 71-3-537 instead requires a creditor to acknowledge satisfaction after lien indebtedness is paid; that is a recorded-lien satisfaction rule, not a payment-stage waiver form. |
| Noncompliance, remedies, and transition traps | A construction-contract provision requiring an advance (pre-payment) lien or bond waiver is 'void' (MCA § 28-2-723) — it cannot be enforced against the claimant, who keeps the lien and bond rights the clause tried to strip. There is no separate statutory penalty or nonconforming-waiver form rule. No pending bill would change this. |
Requirements one by one
An advance waiver is void
Montana's construction-lien rules live in Title 71, chapter 3, part 5, but the rule that matters most for waivers sits in the contracts title. MCA § 28-2-723 says a construction contract "may not contain provisions requiring a contractor, subcontractor, or material supplier to waive the right to a construction lien or a right to a claim against a payment bond before" that party "has been paid for the labor, materials, or both … furnished." So an owner or general contractor cannot use the contract to force a "no-lien" promise up front. A clause that tries to do so is void, and the worker keeps the lien — and the payment-bond claim — that the clause tried to take away.
Two features are worth noting. First, the ban is not limited to the lien; it also protects a claim against a payment bond, so a contract cannot force a party to sign away bond rights in advance either. Second, the line the statute draws is about both the contract requirement and timing. It forbids a construction contract from requiring the waiver before payment; it does not prescribe the effect or wording of a waiver requested after payment.
There is no statutory waiver form
Montana prescribes no waiver form. Section 71-3-532 supplies the separate "notice of the right to claim a lien," and § 71-3-536 supplies the recorded lien notice, but the construction-lien part contains nothing comparable for a payment-stage waiver. There is no statutory conditional-versus- unconditional wording, no progress-versus-final form, no required warning, and no field list. Section 28-2-723 also states no check-clearance or failed-payment rule for a waiver requested after payment.
Section 71-3-537 is also different: once lien indebtedness has been paid and satisfied, it requires the creditor to acknowledge satisfaction and creates liability for injury and action costs if the creditor fails to do so. That rule addresses satisfaction after lien indebtedness exists, not a pre-recording payment-stage waiver.
What trips people up
The § 28-2-723 ban targets what the construction contract can require before payment. It does not state a separate rule for a voluntary payment-stage waiver or declare that every waiver requested at or after payment is valid. Those questions therefore cannot be answered from this anti-waiver section alone.
Watch the payment-bond half of the rule. Section 28-2-723 voids an advance waiver of "a right to a claim against a payment bond" just as it voids an advance lien waiver. A contractor asked to sign broad "waiver of all claims" language before payment should know that a pre-payment demand to give up bond rights is also unenforceable under this section.
Common questions
Can a Montana construction contract make me waive lien rights before I'm paid? No. MCA § 28-2-723 voids any contract provision requiring a contractor, subcontractor, or material supplier to waive a construction lien or a payment-bond claim before being paid for the work furnished.
Does Montana have a required lien-waiver form? No. The construction-lien statutes include notice-of-right-to-claim-lien and recorded-lien forms but no payment-stage waiver form.
If I sign a waiver after payment, is it effective even if the check bounces? Section 28-2-723 does not answer that question. It bars a construction contract from requiring the waiver before payment, but supplies no failed-payment or check-clearance rule for a later waiver.
