Choosing the next professional question when source documents disagree
A guide for Illinois residents on how to reconcile conflicting property information by asking the right professional questions.
The short answer
When source documents disagree—such as a disclosure report and an inspection result—prioritize evidence-based professional opinions. Do not rely on speculation. Direct your questions to the specific expert (inspector, attorney, or mitigation specialist) to determine which source is the most current or applicable to your situation. Document these responses to clarify your path forward under the Illinois Disclosure Act.
Prioritizing Expert Opinions
If an inspector and a seller disagree on a defect, the inspector’s report often provides the technical basis for further inquiry.
Ask the inspector: 'On what standard did you base your finding of a defect compared to the seller's statement?'
Worksheet: Create a table with 'Source A' and 'Source B' to identify exactly where the statements conflict.
Consulting Legal Counsel
Legal counsel can interpret if a conflict triggers specific disclosure requirements under the Residential Real Property Disclosure Act.
Ask your attorney: 'Does this conflict in reported information constitute a misrepresentation requiring further documentation?'
Hypothetical planning: Seek a written explanation from the seller regarding the discrepancy rather than verbal hearsay.
Verifying Technical Credentials
If conflicting reports involve radon or lead, verify the licensing of both reporting parties with IEMA or the EPA.
Ask the professional: 'What is your current license number and were these results generated following state-approved testing protocols?'
Planning example: If a report is outdated, prioritize the most recent professional assessment.
Documenting Resolution Attempts
Keep records of all correspondence when clarifying discrepancies. This provides a clear trail of your due diligence.
Ask your agent: 'How should we formally present these conflicting reports to the seller to request a supplemental disclosure?'
Planning example: Maintain a folder for each discrepancy, noting the date, the professional consulted, and the advice received.
Checklist
- Identify the core point of disagreement.
- Verify licensing for all involved experts.
- Check document dates for current relevance.
- Draft written inquiries for the seller.
- Consult legal counsel on contractual rights.
Common questions
Which document is legally binding if they conflict?
No single document is automatically binding. The Disclosure Act requires honesty, and professional reports provide evidence. Consult an attorney to evaluate the weight of each source.
Should I trust the seller's word or my inspector?
The inspector provides a professional opinion based on current physical evidence. If you have concerns, ask the seller for documentation to support their conflicting claim.
