Assumed Business Name Registration ($50)
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.
The Clerk's office also allows the public to search for businesses and owners by name, address or registration number.
