- Illinois Supreme Court Rule 218 governs pretrial procedure and requires parties to disclose all trial exhibits in their pretrial memorandum.

- Illinois courts require exhibit stickers in the lower right corner of the first page so the marking does not obscure document content.
- eFileIL caps individual documents at 25 MB and is mandatory for represented parties; password-protected PDFs are rejected.
- Cook County Rule 4.1 requires exhibits to be exchanged 30 days before the pretrial conference, and every filing must include the attorney's ARDC Attorney ID Number.
- Lake County Rule 2-4.04 applies to cases with 50 or more trial documents and requires tabbed binders plus a detailed exhibit index.
- Illinois Supreme Court Rule 455, effective January 2023, requires criminal case exhibits to be retained for 30 days after sentencing or appeal disposition.

Overview
Illinois circuit courts use eFileIL for mandatory electronic filing.

Lake County Rule 2-4.04Common eFileIL Issues
File Size Exceeds 25 MB Limit
Solution: Split large exhibits into parts. Label clearly (e.g., "Exhibit 5, Part 1 of 3"). ExhibitPrep exports individual files that stay within eFileIL limits.
Missing Attorney ID Number (Cook County)
Solution: Cook County requires Attorney ID Numbers on all filings. Ensure your ARDC number appears on pleadings and exhibit submissions.
Unredacted Personal Identifiers
Solution: Redact SSN (except last 4 digits), financial accounts, birth dates (year only), and minor names per Supreme Court Rules before stamping.
Password-Protected PDFs
Solution: Remove password protection before e-filing. Courts cannot accept secured PDFs. ExhibitPrep requires unprotected source files.
