Fictitious Business Name Statements (DBAs)
A Fictitious Business Name (FBN) or Doing Business As (DBA) statement is required when the business name does not include the surname of the individual owner(s) and each of the partners; or the business name suggests the existence of additional owners; or the nature of the business entity is not clearly evident by the name of the business. For example, Bill Smith and Sons Plumbing would require an FBN because the name implies additional owners, Bill Smith Plumbing does not require an FBN. Bill Smith Industries would require an FBN because it does not identify the nature of the business.
