Who must file:

  • Anyone doing business for profit under a fictitious name, as governed by Business and Professions Code § 17900.

Information regarding the filing of a Fictitious Business Name Statement:

Be certain the information in the statement is correct and complete before filing it. You cannot make changes to the statement once it has been filed. Any changes would require the filing of a new statement, payment of the filing fees again, and publication in a newspaper in Sonoma County.

When you file a fictitious business name statement, it does not reserve the name for your exclusive use. The filing is for consumer protection, and is a requirement under Business & Professions Code § 17900.

The County Clerk's Office cannot refuse to file a fictitious business name statement because the name is already being used by someone else.

If there is a conflict between business owners using the same or similar names, it becomes a legal matter between the business owners.

Business and Residence Addresses - State Law requires the disclosure of actual street addresses for the place of business and EACH owner's place of residence. Do not use a mailing address such as a P.O. Box, postal suite, postal drop box, mailing suite, etc.

For the business address, use the address of the physical location of the principal place of business. If you operate the business out of your home, use the home address. If no street address is assigned, give the exact location of the business plus the rural route, slip number, or other number assigned.

Your residence address (where you live) must be listed under the registrant information. For the residence address, use the street address, not a mailing address. If the registrant is a corporation/LLC, an address (should not be a PO Box) and the State of Incorporation/Organization must be listed.

All information contained in the statement is a PUBLIC record, including your residence address. Anyone can purchase copies of the statement.

All original filings as well as new filings with a change in the facts from the previous filing must be published. The statement must be published in an adjudicated newspaper, once per week for four consecutive weeks. The first publication must begin within thirty days of the date the statement was filed in the County Clerk's Office. A list of newspapers is available from our office.

The proof of publication must be filed in the County Clerk's Office. Please check with the newspaper to see if they will forward the original to our office for filing.

The statement is a REFILE WITH NO CHANGES if NO information (including residence address of the owner(s)) changed from the previous filing. Statements filed as a REFILE WITH NO CHANGES do not need to be published provided they are refiled within 40 days of the expiration of the current statement. The customer is responsible for determining whether publication on a refiled statement is required.

The statement is valid for five years from the date it is filed in the County Clerk's Office, unless there is a change in any information (except the registered owners address). A change requires a new statement be filed within 40 days of the change. The new statement would also need to be published.

For questions regarding the filing of your fictitious business name statement, please call (707) 565-3800, or come to our office at 2300 County Center Drive, Ste. B177, Santa Rosa, CA 95403.
