Chicago, Illinois Court eFiling Overview

Courts in Chicago (Cook County), Illinois, use a mandatory electronic filing (eFiling) system for most case types. Attorneys and self-represented litigants must submit documents electronically through the approved statewide platform unless an exemption applies.

eFiling is governed by:

  • Illinois Supreme Court Rules
  • Cook County Circuit Court Local Rules
  • Statewide eFileIL system requirements

Is eFiling Mandatory in Chicago Courts?

Common exceptions may include:

  • Certain criminal filings
  • Emergency filings (when eFiling is unavailable)
  • Approved hardship or fee-waiver exemptions
  • Even when exemptions apply, courts often require subsequent electronic submission.

What Is the Official eFiling System for Chicago?

eFileIL allows filers to:

  • Submit pleadings, motions, and court documents online
  • Pay filing fees electronically
  • Receive confirmation of accepted or rejected filings
  • Track filing status in real time
  • Access stamped copies once accepted


⚠️ Important: Documents are not officially filed until the clerk accepts the submission.

  • Clerk review and acceptance occur during court business hours

  • PDF format required
  • Searchable text (OCR recommended)
  • Proper document titles
  • Correct case number and case type
