Key Takeaways
- Required since October 1, 2023: House Bill 296 (Ch. 375, L. 2023) created Mont. Code Ann. §§ 70-20-501 to 70-20-505.
- "Non-disclosure" means price, not defects: sale prices stay confidential under § 15-7-308; known defects must be disclosed.
- The 3-day rule: unless both sides agree otherwise in writing, the contract is not effective until 3 days after the buyer receives the statement.
- Six exemptions: court-ordered sales, divorce transfers, foreclosures, co-owner buyouts, family transfers, and a buyer waiver in the contract.
- Two separate disclosures: the water right disclosure on the Realty Transfer Certificate and the federal lead paint rule for pre-1978 houses.
- A waiver removes the form, not fraud law: hiding a known defect is still actual fraud under § 28-2-405.
Montana seller disclosure requirements are newer than many sellers expect. Until October 1, 2023, no Montana statute required a seller to give the buyer a written list of known problems. House Bill 296 changed that, and the statement now belongs in your math whether you list or sell directly.
Plenty of websites still call Montana a "non-disclosure state." That label describes sale prices, not defects. This guide separates the two and shows how a direct cash sale fits inside the statute.

Let's chatIs Montana a Non-Disclosure State?
Montana is a non-disclosure state only for sale prices: what you sell for stays confidential, but known defects must be disclosed in writing under the 2023 law. The price rule comes from the Realty Transfer Act. Every deed presented for recording needs a Realty Transfer Certificate that declares the price paid (Mont. Code Ann. § 15-7-305). Under § 15-7-308, that certificate and its contents "are not a public record" and must be held confidential by the county clerk and recorder and the Department of Revenue. The legislature gave its reason in the text: "the demands of individual privacy outweigh the merits of public disclosure."
That rule keeps your sale price out of public records. It says nothing about the roof or the septic system. A page that tells Montana sellers they need not disclose defects mixes up two separate laws.
What changed in 2023
Before 2023, the statutory duty fell on licensed agents. A seller's agent must disclose "any adverse material facts that concern the property and that are known to the seller agent" (Mont. Code Ann. § 37-51-313(3)(a)). An owner selling alone had no statutory form.
House Bill 296, enacted as Chapter 375, Laws of 2023, put the duty on the seller, with or without an agent. The enrolled bill has no effective-date section, so Montana's default rule applies: a statute takes effect on October 1 following its passage and approval (Mont. Code Ann. § 1-2-201). That puts the start date at October 1, 2023.
What Are Montana's Seller Disclosure Requirements?
Montana's seller disclosure requirements direct the seller of a one-to-four-unit house to give the buyer a written statement of known adverse material facts, before or when the contract is signed. The core sentence of Mont. Code Ann. § 70-20-502(1) reads:
"In any transfer of residential real property in the state, the seller shall provide a disclosure statement to a buyer disclosing any adverse material facts that concern the residential real property and of which the seller has actual knowledge."
The definitions that set the scope
Three definitions in § 70-20-501 decide who is covered and what counts:
- Adverse material fact: "a condition, malfunction, or problem that would have a materially adverse effect on the monetary value of real property, that affects the structural integrity of any improvements," or that presents a documented health risk to occupants.
- Residential real property: a building with one to four dwelling units, or an individually owned unit in a building of any size, including condominiums and mixed-use buildings.
- Transfer: a sale, conveyance, exchange, or option to purchase by written instrument, for consideration.
Actual knowledge, with no duty to investigate
The standard is what you know, not what an inspector might find. The statement must say the seller "is not obligated to investigate" (§ 70-20-502(2)(b)), that it is not a warranty, and that it does not replace the buyer's inspections.
Actual knowledge still reaches further than many sellers assume. A past inspection report, a repair estimate, or an insurance claim all count. If a document in your files describes a problem, it belongs on the statement.
What the Montana Property Disclosure Statement Must Cover
A Montana property disclosure statement must address at least ten subjects listed in § 70-20-502(1)(a) to (j), each limited to what the seller actually knows. The statute sets the minimum content but does not prescribe a state form.
| Category | The Statute's Words | Examples |
|---|---|---|
| Title and water (a), (b) | "matters affecting legal ownership or title" or "the seller's ability to transfer"; "matters affecting water service" or "the water source" | A boundary dispute, a shared well with no written agreement |
| Wastewater and utilities (c), (d) | "matters affecting the system for wastewater treatment"; "information concerning utility connections" | A drainfield that backs up |
| Structure and systems (e) | "water intrusion," and problems with "any well, septic system, roof, foundation, plumbing, electrical system, heating system, windows, doors, or appliances" | An ice-dam roof leak, a failing boiler |
| Unpermitted work (f) | "whether any substantial additions or alterations have been made" without "a building permit" | A basement bedroom finished without a permit |
| Hazardous materials and testing (g), (i) | "hazardous materials or pest infestations"; whether any part "has been tested or treated for asbestos, radon gas, lead-based paint, mold, methamphetamine, fuel or chemical storage tanks, or contaminated soil or water" | A radon test result, a buried heating oil tank |
| Soils and drainage (h) | "any problems with settling, soil, standing water, or drainage" | Spring runoff pooling at the foundation |
| Catch-all (j) | "any other adverse material fact" | A known code violation |
Two categories reach past your lot line
Subsections (g) and (h) cover problems "on the residential real property or in the immediate area." A neighbor's grading that you know sends meltwater into your crawlspace is the kind of fact this captures.
The 3-Day Rule: When a Montana Contract Takes Effect
Unless both sides agree otherwise in writing, a Montana purchase contract is not effective until 3 days after the buyer receives the disclosure statement. The buyer may withdraw without penalty during that pause, under § 70-20-502(2)(c):
"...unless the buyer and seller have otherwise agreed in writing, any contract is not effective until 3 days after the buyer has received the disclosure statement, and during that delay the prospective buyer may withdraw or rescind any contract to purchase the residential real property without penalty."
Delivery must happen "prior to or contemporaneously with the execution of a contract," directly or through an agent, to the buyer or the buyer's agent. In a listed sale, this pause stacks on top of inspection and financing contingencies.
What happens if the statement arrives late
A statement delivered after the contract is signed gives the buyer 3 days from delivery to rescind (Mont. Code Ann. § 70-20-504(1)). The buyer must deliver "a separately signed written statement of rescission" to the seller or the seller's representative.
Two escape valves exist. The parties can agree otherwise in writing, and under § 70-20-504(2) "the buyer may waive the right to rescind in any offer to purchase."
Which Montana Sales Are Exempt From the Disclosure Statement?
Six kinds of transfers are exempt from the written statement: court-ordered, divorce, foreclosure, co-owner, close family, and buyer-waiver transfers (§ 70-20-503).
| Exempt Transfer | Plain-English Example |
|---|---|
| (1) Transfers under a court order, including probate, bankruptcy, and eminent domain | A probate court orders the personal representative to sell the house during administration of the estate |
| (2) Transfers between spouses under a dissolution or legal separation decree | One spouse deeds the house to the other as the divorce decree requires |
| (3) Transfers after default, including foreclosure sales and the lender's later resale | A lender that took the house back at a trustee's sale resells it |
| (4) Transfers from one co-owner to other co-owners | One sibling buys out the other sibling's share of an inherited house |
| (5) Transfers to a spouse, child, or parent of the seller or any other owner | A parent sells the house to an adult son or daughter |
| (6) Buyer waiver in the contract, made when the buyer submits the offer | A cash buyer's offer states that the buyer waives the disclosure statement |
The probate exemption is narrower than it looks
The first exemption covers "a transfer ordered by a probate court during the administration of a decedent's estate." Not every estate sale is ordered by a court. A personal representative who sells without a specific order may not fit the exemption.
An heir who already holds title and sells later is not on the list either. See our guide to selling an inherited house in Montana, and ask the estate's attorney whether a sale is court-ordered.
Section 70-20-503 removes only "the written disclosure statement." It does not authorize a seller to hide a known defect. Fraud law still applies to exempt and waived sales.
Other Disclosures at a Montana Closing: Water Rights and Lead Paint
Two more disclosures sit outside the 2023 law: the water right disclosure on the Realty Transfer Certificate, and the federal lead-based paint disclosure for houses built before 1978. A waiver of the state statement does not remove either one.
The water right disclosure on the Realty Transfer Certificate
Unless the house is served by a public water supply, the Realty Transfer Certificate "must contain a water rights disclosure" (Mont. Code Ann. § 85-2-424(1)). In it, the seller acknowledges at or before closing whether any water rights are associated with the land and whether they will transfer.
Part 7 of the Department of Revenue's form has four boxes: public water supply, no water rights on record, all rights transferring, or rights divided or severed (Form RTC, V4 12/2025). Transferring all rights uses DNRC Form 608. Dividing or severing them requires DNRC Form 640, Certification of Water Right Ownership Update, signed by both parties.
The form carries a warning worth reading twice: if a recorded document is silent, "the water rights automatically pass with the land by operation of law." The DNRC ownership update page lists current forms and fees.
The federal lead paint rule for pre-1978 houses
Sellers of housing built before 1978 must meet a separate federal rule under 40 C.F.R. part 745, subpart F (U.S. EPA, Real Estate Disclosure). The seller must:
- Give the buyer the EPA lead pamphlet.
- Disclose known lead-based paint, hazards, and available reports.
- Include the Lead Warning Statement with the contract.
- Offer a 10-day period for a lead inspection or risk assessment, which the buyer may waive.
- Keep a signed copy for three years.
The federal rule has its own narrow exceptions, such as foreclosure sales. It does not borrow Montana's exemption list.
What Happens If a Montana Seller Hides a Defect?
Montana's disclosure statute has no penalty section of its own, so a hidden defect is judged under the state's general fraud and misrepresentation law. Montana defines actual fraud to include "the suppression of that which is true by one having knowledge or belief of the fact," when done to induce the other party to sign (Mont. Code Ann. § 28-2-405). Leaving a known septic failure off the statement fits that description.
What the purpose clause does for sellers
Section 70-20-505 sets three limits that protect a careful seller (§ 70-20-505):
- The statement "does not constitute a warranty of any kind" by the seller or the seller's agent.
- It is a disclosure by the seller only, not by the agent.
- The seller "may not be responsible" for errors based on information from "a reliable third-party, including a local governing agency."
The practical rule: disclose what you know, attach the report that told you, and say plainly when you do not know.
How Montana Seller Disclosure Requirements Work in a Direct Cash Sale
A direct cash sale is still a covered transfer, but the buyer can waive the Montana property disclosure statement in the contract and waive the late-delivery rescission right in the offer. Propcash is a direct cash homebuyer that buys houses as-is. You tell us what you know, and Propcash typically prices known defects into one data-backed cash offer, with the reasoning shown. A disclosed problem can become part of the number, not a reason to renegotiate. Waiver or not, share what you know.
The listing math a disclosed defect changes
Redfin reports a Montana median sale price of $522,823 in August 2026, up 4.6% year over year, with a median of 85 days on market (Redfin, August 2026). Separately, Zillow's typical home value for the state was $471,746, up 2.0% from a year earlier (Zillow ZHVI, August 2026).
In Billings, the median sale price was $390,000 over the three months ending August 2026, and houses took a median of 61 days to sell (Redfin, August 2026). None of those figures shows the repair credits a disclosed defect can cost a listed house. Insurance can add another hurdle; see selling a Missoula house when wildfire insurance is the problem.
What a direct sale can remove
A cash sale has no lender appraisal and no financing contingency. Montana closings typically run through a title or escrow company, and cash sales can close in as few as 7 days on a date you pick. Sellers pay no fees or commissions.

Let's chatFrequently Asked Questions
Is Montana a non-disclosure state for house defects?
Montana is not a non-disclosure state for house defects. Montana is a non-disclosure state only for sale prices, which stay confidential on the Realty Transfer Certificate under Mont. Code Ann. § 15-7-308. Since October 1, 2023, sellers of one-to-four-unit houses must give buyers a written statement of the adverse material facts they actually know under § 70-20-502.
When does a Montana seller have to deliver the disclosure statement?
The statement must be provided before or at the same time the contract is signed. The seller can deliver it directly or through an agent, to the buyer or the buyer's agent. If it arrives after the contract is signed, the buyer gets 3 days from delivery to rescind in a separately signed writing, unless that right was waived in the offer.
Can a Montana buyer back out after receiving the disclosure statement?
A Montana buyer can back out after receiving the disclosure statement in most cases. The statement must tell the buyer that, unless the parties agreed otherwise in writing, the contract is not effective until 3 days after the buyer receives it. During that pause the buyer may withdraw or rescind without penalty under Mont. Code Ann. § 70-20-502(2)(c).
Can a buyer waive the Montana property disclosure statement?
A buyer can waive the Montana property disclosure statement. Mont. Code Ann. § 70-20-503(6) exempts a sale in which the buyer waived the right to receive the statement in the contract at the time of submitting the offer. A waiver removes the written form only. Montana fraud law still applies to a seller who hides a known defect.
Does a personal representative selling an inherited Montana house have to give a disclosure statement?
Only a transfer made under a court order, such as a sale ordered by a probate court during administration of the estate, is exempt under § 70-20-503(1). A personal representative who sells without a specific court order, or an heir who already holds title, may still owe the statement. The estate's attorney can confirm which applies.
Does a Montana seller have to disclose water rights?
Yes, unless the house is served by a public water supply. Mont. Code Ann. § 85-2-424 requires the Realty Transfer Certificate to include a water rights disclosure stating whether any water rights go with the land. That disclosure is separate from the 2023 seller disclosure statement and is completed at or before closing.
