Washington Seller Disclosure - Washington Seller Disclosure Requirements: What You Must Reveal in 2026

In Washington State, sellers must deliver a completed Seller Disclosure Statement (Form 17) to buyers no later than 5 business days after mutual acceptance of the purchase agreement, with buyers having a 3-day window to rescind the agreement. This is a critical step in the home selling process for Washington residents in 2026, as it ensures transparency and protects both parties during the transaction.

Key Takeaways

  • Sellers must provide a completed Seller Disclosure Statement (Form 17) within 5 business days after mutual acceptance.
  • Buyers have a 3-day right to rescind the purchase agreement after receiving the disclosure.
  • All known issues, such as structural problems and environmental hazards, must be disclosed.
  • Sellers are not required to disclose deaths or the presence of nearby sex offenders.

What Are the Current Seller Disclosure Requirements in Washington?

In 2026, Washington State law mandates that sellers of improved residential real property complete and deliver a Seller Disclosure Statement (Form 17) within five business days following the mutual acceptance of a purchase and sale agreement. This requirement is crucial for ensuring that buyers are informed of any known issues with the property. After receiving the disclosure, buyers have three business days to rescind the agreement, providing them with a safeguard against unexpected property issues.

What Must Be Disclosed in the Seller Disclosure Statement?

Sellers are required to disclose any known issues based on their actual knowledge. This includes roof leaks, foundation or structural problems, electrical defects, exterior drainage or standing water issues, flooding history, water damage, heating system functionality, sewage or plumbing defects, hazardous materials, boundary disputes, and wood-destroying insect damage. The disclosure must be thorough and honest to avoid potential legal liabilities.

How Does the Disclosure Process Protect Buyers and Sellers?

The disclosure process in Washington serves to protect both buyers and sellers by promoting transparency. By clearly outlining the condition of the property, sellers can shield themselves from future disputes, while buyers are provided with the information necessary to make an informed decision. The 3-day rescission period further empowers buyers to back out of the deal if they discover issues through the disclosure.

Are There Exceptions to the Disclosure Requirement?

Yes, certain transactions are exempt from the disclosure requirement. These include transfers through foreclosure, gifts between family members, transfers between divorcing spouses or domestic partners, co-owner buyouts, and transfers by personal representatives of an estate. Additionally, if a buyer waives their right to the disclosure, the requirement may be bypassed, though this is generally discouraged.

What Should Sellers Do if New Issues Arise Before Closing?

If sellers discover new issues that make any part of the disclosure inaccurate before closing, they must amend the disclosure and provide the updated version to the buyer. This triggers another 3-day rescission period for the buyer. Alternatively, if the seller corrects the issue at least three days before closing, no amendment is necessary, provided the original disclosure then remains accurate.
