Illinois Department of Financial and Professional Regulation, Division of Professional Regulation

How the official source says to file

• Submit the online complaint linked from the official page, or complete the printable form and mail it to the Complaint Intake Unit, 555 W. Monroe St., 5th Floor, Chicago, IL 60661. The form says complaints must be written and are not taken by telephone or walk-in.
• Include full names, professional category, contact information, incident dates and county, factual details, and copies of supporting documents. Keep originals. Use a separate form for each profession.
• The online narrative limit is 3,000 characters and it rejects URLs. The agency page gives placeholder instructions when the respondent’s phone number or street address is unknown.

What this route may not provide

The complaint form says IDFPR cannot act as your lawyer, represent you in court, or give legal advice. This is a regulatory report. The checked intake materials did not establish a compensation remedy, so ask about appropriate separate routes if repayment or injury damages are your goal.

Do not guess about confidentiality

The filing page says complaints and investigation information are confidential under Illinois law, with stated exceptions for law enforcement, relevant regulators, and lawful subpoenas. It does not establish that an identified complainant’s identity is withheld from the practitioner. Anonymous-filing policy was not established; ask intake before relying on anonymity.

Filing deadline and completion estimate not established

A filing deadline was not established by this check; ask promptly. The form promises acknowledgment after receipt and opening, with a case number for later correspondence, but supplies no completion guarantee.

What may happen after filing

Intake may contact you by email or telephone for more information. Keep the acknowledgment and case number, and ask the division about later investigative stages; the checked intake materials do not describe the full sequence.
