Check off anything that applies to your Montana property. If you’re unsure about something, make a note to ask your real estate agent or investigate further. The goal is to help you think through what needs to be documented and disclosed during the sale process.

What is not required to be disclosed? Montana law does not require you to disclose if someone died in the home, if a previous occupant had a communicable disease, or if a sex offender lives nearby. You’re also not obligated to disclose neighborhood rumors, paranormal activity, or personal reasons for selling, unless you are directly asked and your answer could be misleading.

Common mistakes sellers make on the disclosure form

Here are some of the most common missteps sellers make when filling out the Montana Owner’s Property Disclosure Statement:

Checking “yes” without providing an explanation: If you check a yes box that includes an “Explain” line, not providing the details could lead to a delay in the sale of your home.
Guessing instead of explaining: If you’re not sure about something, don’t make assumptions — just state that you don’t know or add an explanation.
Failing to attach supporting documents: Inspection reports, permits, repair invoices, and warranties help verify your disclosures.
Not disclosing repaired issues: Even if you’ve fixed a problem listed on the form, like a roof leak or foundation issue, it still needs to be reported.
Minimizing or softening the truth: Downplaying a defect can open you up to legal risk if the buyer later discovers the issue was worse than you described.

What if you fail to disclose something important?

If you fail to disclose a known material fact about your Montana home, the buyer may have grounds to cancel the contract or sue you after the sale. In some cases, nondisclosure can be considered fraud under Montana law, particularly if the omission appears intentional. Being upfront now helps prevent bigger headaches later.

When and how buyers review the disclosure

Under Montana’s standard purchase contract, you’re expected to provide a completed Owner’s Property Disclosure Statement within five days of contract acceptance. The buyer then has a set review period, typically 10 to 14 days, to examine the form and decide whether to proceed, request repairs, or cancel the deal.
