Illinois attorney lookup with the ARDC.
In Illinois one agency, the ARDC, handles both registration and discipline. This page explains what its Lawyer Search shows and how to avoid picking the wrong lawyer.
Use the official register for the answer: the Attorney Registration and Disciplinary Commission of Illinois (ARDC) record is authoritative, and this page cannot confirm anyone’s licence or standing. Open the register below, compare the details with the person who contacted you, and confirm with the regulator if anything does not match.
How the IL register is searched and what it shows
How the register is searched:
- The ARDC tells the public to use its Lawyer Search tool to find a lawyer’s public information. This page cannot confirm whether the search accepts a registration number; the ARDC’s own form shows the fields.
What the regulator says it shows:
- The ARDC says it gives courts and the public information including business contact information, whether the lawyer is currently registered and authorized to practise, whether the lawyer has been disciplined in the past, whether there are pending formal complaints, and whether the lawyer reports legal malpractice insurance.

The register belongs to the Attorney Registration and Disciplinary Commission of Illinois (ARDC). Open it, search for the person, and treat its record as the authoritative answer.
The attorney registration number in Illinois
Illinois uses an attorney registration number. The ARDC lists each lawyer’s attorney number on its public discipline pages, which helps separate lawyers with similar names. The pages reviewed state no fixed digit length.
Where to find discipline records
Public discipline appears in the Lawyer Search result. The ARDC also publishes complaints and answers, hearing board and review board reports, and summaries of recent Illinois Supreme Court decisions.
Limits to keep in mind
- Lawyers with similar names are common; the ARDC’s own lists tell readers to check carefully that they have selected the correct lawyer. Use the attorney number to disambiguate.
- The ARDC says it cannot decide malpractice claims or make lawyer referrals.
This page does not validate a number’s format or check a number against any list; only the official register can do that.
