Illinois Seller Disclosure & Property Defects FAQ

Seller Disclosure & Defect Questions

Illinois disclosure disputes usually turn on three questions: Was the problem a material defect? Did the seller actually know about it? What was disclosed, and when?

What Must an Illinois Seller Disclose?

For covered transactions, the Illinois Residential Real Property Disclosure Act generally requires the seller to provide the statutory report before contract signing and disclose material defects actually known to the seller.

The Act does not require the seller to conduct a special investigation to discover unknown defects.

What Is a Material Defect?

The statutory form describes a material defect as a condition that substantially adversely affects value or significantly impairs the health or safety of future occupants, unless the seller reasonably believes it has been corrected.

Does “As Is” Eliminate Disclosure Duties?

No. An “as is” sale can limit repair expectations, but it does not erase the Disclosure Act when the Act applies.

What If the Seller Learns About a Problem Before Closing?

If the seller becomes aware before closing of an error, inaccuracy or omission in a prior disclosure, Illinois law generally requires a written supplemental disclosure.

What If a Material Defect Is Disclosed Late?

When a material defect is first disclosed after contract signing, Illinois law can provide a buyer with time-sensitive rights. The applicable rule and deadline depend on how and when the disclosure was made and on current law.

What If the Seller Knowingly Gives False Information?

A seller who knowingly violates the Act or knowingly provides false disclosure information may be liable for actual damages and court costs. The court may also award reasonable attorney’s fees to the prevailing party.

How Can Seller Knowledge Be Shown?

Evidence can include prior repairs, contractor communications, insurance claims, recurring damage, earlier reports, permits, photographs or messages. No single item automatically proves liability; the evidence must be considered with the contract and disclosures.

Are There Deadlines for Seller-Disclosure Claims?

Claims involving seller disclosures can be subject to short statutory filing periods, and other legal theories may have different limitation periods. Which deadline applies depends on the claim, facts and current law.

Does the Disclosure Report Replace an Inspection?

No. The statutory report expressly states that it is not a substitute for inspections or warranties the parties choose to obtain or negotiate.
