Yes, sellers are required by law to disclose any known material information about the property’s condition—even if those conditions are revealed after the completion of the seller’s disclosure notice. While the Texas Property Code does not create a continuing duty or obligation to update the Seller’s Disclosure Notice, if information in the notice is no longer true, the seller may have a common-law duty to correct any misstatements or false impressions. The Texas REALTORS® Update to Seller’s Disclosure Notice (TXR 1418) form can be used to provide the newly discovered property information to prospective buyers.
