What is the Washington seller disclosure form?
The Washington seller disclosure form, or Seller’s Disclosure Statement, is a 6-page document developed by the Washington State Legislature. It’s designed to help you disclose any known issues or facts about your home that could impact its value or a buyer’s decision to proceed.
Washington law requires sellers to disclose all material facts — in other words, anything that could impact the buyer’s use or enjoyment of the property. The Washington Seller’s Disclosure Statement form acts as a guide to help you do this thoroughly. It covers everything from structural issues and past repairs to neighborhood conditions and HOA rules.
