Reading a seller disclosure without treating it as a warranty
Understanding that Illinois seller disclosure forms are not warranties and how to correctly use this information during your home buying process.
The short answer
The Illinois Residential Real Property Disclosure form requires sellers to reveal known material defects; however, it is not a warranty or guarantee of the home's condition. Sellers are not required to investigate the property beyond their actual knowledge. Rely on this document as a starting point for your own investigations rather than as a promise of a defect-free property.
Actual Knowledge vs. Warranties
A seller is only obligated to disclose defects of which they have actual knowledge. They are not liable for unknown issues or defects they reasonably believed were corrected. Because of this, you should never treat the disclosure as a comprehensive warranty of the home's systems.
Defining Material Defects
Material defects are conditions that significantly impair safety or health, or substantially affect the property's value. Sellers must report these items. If you discover a defect not listed, consider if it meets the legal definition and how it impacts your transaction.
Supplementing the Disclosure
If a seller learns of a new defect after the initial disclosure, they must provide a supplemental report. Always verify if any supplements have been issued before your closing date to ensure you have the most current information available.
Information Planning Example
Would cross-referencing the disclosure form with the MLS description and listing major systems for your inspector help you clarify property conditions?
Checklist
- Obtain the signed Residential Real Property Disclosure form.
- Review the form specifically for known material defects.
- Verify all sections are filled out completely.
- Schedule an inspection to verify the condition of mentioned systems.
- Keep the disclosure as part of your permanent home records.
Common questions
What if the seller claims they do not know about a major defect?
If you suspect a defect exists but the seller denies knowledge, consult your real estate professional about the best way to conduct further independent investigations.
Can I sue if the seller lied on the disclosure?
Sellers who provide false information can be held liable for actual damages and court costs. Consult with a qualified legal professional to understand your rights regarding potential misrepresentation.
