Any time a seller has new information about the condition of the property the sellers disclosure should be updated. Here is an explanation from the Texas Association of Realtors (TAR).
“While the Texas Property Code doesn’t state that a seller is obligated to update the form, common law requires a seller to disclose new information that makes an earlier representation misleading or untrue. This means that the seller must present the new information to the buyer one way or another once the seller becomes aware that his previous representation in the Seller’s Disclosure Notice is no longer true.
Providing an updated Seller’s Disclosure Notice to the buyer is a great way to satisfy common law requirements. Not only will the seller have written evidence that the seller made the buyer aware of the new information, but the seller can then use the updated form going forward (without having to attach an additional disclosure regarding new information).”
New information can result from an event (storm damage, heating and cooling system failure, etc.) and inspections by prospective buyers.
“A broker or seller who receives an inspection report is charged with knowledge of the information in the report. This is true even if the broker or seller does not open the report or disagrees with the information contained in the report. If an inspection report reveals material defects, the seller and the broker are obliged to disclose those defects to subsequent potential buyers.
The seller and broker may choose to disclose the defects orally, but that may be imprudent since no record of the disclosure would exist; summarize the defects in some written communication to the subsequent purchaser, but that may create a risk that some important information may be edited out. The seller and broker should provide a copy of the report to the subsequent potential purchaser along with the seller’s disclosure notice, thereby providing all of the information the seller and broker have with regard to any know defects.
If the seller strongly believes the information in the inspection report is incorrect, the seller could have another inspection performed. If this is done, the seller should provide both reports to subsequent buyers. The TAR Seller’s Disclosure Notice (TAR 1406) asks the seller to identify and attach copies of previous inspection reports. TAR’s notice cautions the buyer against relying on previous reports as a reflection of the current condition of property and suggests that the buyer employ an inspector of the buyer’s choice to inspect the property.”
