File a DBA (fictitious business name) in Ann Arbor, MI
A DBA ("doing business as"), also called a fictitious business name or FBN, lets a business operate under a name other than its owner's legal name.
Michigan requires a sole proprietor who does business under a name other than their own to file that name. The filing goes to the County Clerk of the county where the business is located.
