Assumed Business Name Registration
The Clerk's office registers business names known as "assumed names" for new businesses in accordance with Illinois law.
An assumed name is issued to any business entity that uses a name other than the name(s) of the individual(s) who own or operate the business. For example, a business called "John Jones, P.C." (i.e. owner's full name and title) does not have to file an assumed name, but "Jones Wrecking" does.
