A Fictitious Name is used when a business operates under a name that does not include the last names of all the owners. Fictitious names must be registered in the county in which the business operates. Forms and instructions for filing a Fictitious Name Statement are available online from the County Clerk-Recorder's office (http://www.acgov.org/auditor/clerk/filefbn2.htm). They may also be picked up at the County Clerk-Recorder's Office in Hayward, 24405 Amador St.,Room 108; in Pleasanton, 5672 Stoneridge Dr.; or in Oakland at 1106 Madison St.,Room 211.
