How do I check that a business and corporate lawyer in Illinois is licensed?

Start with the official attorney lookup linked on this page. Match the lawyer’s full name and bar number, and read the current status and any restrictions. Ask the lawyer to confirm authorization for your matter; a directory listing does not establish eligibility.

What does a business and corporate lawyer in Illinois typically charge?

Ask the lawyer whether the work is billed hourly, at a flat rate, on contingency, or another basis. Request a written explanation of the scope, consultation charge, expenses, and payment terms. Published profile information may be incomplete; confirm fees directly.
