Common mistakes sellers make on the disclosure form

Here are some of the most common missteps sellers make when filling out the Maine Seller’s Property Disclosure:

• Checking “yes” without providing an explanation: If you check a yes box that includes an “Explain” line, not providing the details could stall your home sale.
• Guessing instead of explaining: If you’re not sure about something, don’t make assumptions — state clearly that you do not know the answer. Even guessing could open you up to legal headaches. 
• 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 plumbing issue, it still needs to be reported.
• Minimizing or softening the truth: Downplaying a defect can open you up to legal problems if you knowingly minimize a serious issue. 

What if you fail to disclose something important?

If you fail to disclose a known material fact about your Maine 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 Maine law, particularly if the omission appears intentional. Being upfront now helps prevent bigger headaches later.

When and how buyers review the disclosure

Under Maine’s standard purchase contract, you’re expected to provide a completed Seller’s Property Disclosure when the buyer makes their offer to purchase. The buyer then has a set review period, usually 72 hours, to examine the form and decide whether to move forward, request repairs, or cancel the deal.
