The short answer
What Illinois families should know.
A communication may be protected from disclosure by an applicable privilege, but privacy alone does not establish that protection. Illinois Rule of Evidence 501 recognizes privileges arising from the governing law. In discovery, the claim must be evaluated and asserted properly rather than used as a blanket label for inconvenient documents.
Identify the actual protection
Attorney-client communications, attorney work product, and specially protected treatment information can involve different rules and requirements. The participants, purpose, and circumstances matter. An ordinary preexisting document does not become protected merely because it is sent to a lawyer. Give counsel the complete context so the correct legal basis can be identified without unnecessarily spreading the sensitive information.
Assert the claim without disclosing the protected substance
Supreme Court Rule 201 requires an express privilege claim supported by a description of the nature of withheld material and the exact privilege asserted. This permits the issue to be assessed without treating every withheld item as beyond question. Counsel should determine the appropriate description and response. Unilateral deletion or unexplained redaction can create additional problems rather than preserving the protection.
Inadvertent disclosure requires prompt action
Evidence Rule 502 addresses circumstances in which inadvertent disclosure does not waive attorney-client or work-product protection. Reasonable prevention and prompt steps to correct the error matter. Rule 201 also establishes a process after a privilege claim is made for inadvertently produced information. Notify counsel immediately if a protected item appears to have been sent or received by mistake; do not circulate it further.
Protect communications in daily practice
Use private channels for legal advice and avoid casually forwarding counsel’s analysis to friends or group chats. Tell counsel when shared devices, accounts, or other people may have access. Practical precautions cannot create a privilege where the legal requirements are absent, but they can help preserve confidentiality and prevent avoidable disclosure disputes. The safest response to uncertainty is a prompt, specific review of the communication.
