Filing a California fictitious business name means submitting an FBN statement to the county clerk where your business is located within 40 days of first using the name, then publishing that statement in a local newspaper once a week for four consecutive weeks. The registration lasts five years. Skip either step and you lose the right to sue on any contract made under that business name in a California court.1California Legislative Information.

Who Has to File
Sole proprietors need an FBN whenever the business name doesn’t contain the owner’s surname, or when it suggests additional owners through words like “& Company,” “& Associates,” or “& Sons.”2California Legislative Information. California Code BPC – Fictitious Business Names A freelancer named Maria Torres operating as “Torres Web Design” doesn’t need one. “Sunrise Creative Studio” would.
Corporations, LLCs, and limited partnerships have to file whenever they do business under any name other than the exact legal name registered with the California Secretary of State. A corporation called “Pacific Coast Builders, Inc.” that opens a storefront named “Pacific Design Studio” needs an FBN for the storefront name. General partnerships have to file if the business name leaves out any general partner’s surname.2California Legislative Information. California Code BPC – Fictitious Business Names
The 40-day clock starts the first day you use the fictitious name for business.
What Goes on the Statement
California law prescribes the form and the information it has to contain:3California Legislative Information. California Code BPC 17913 – Fictitious Business Name Statement
- The exact fictitious business name or names
- The street address of the principal place of business (no P.O. boxes)
- The full legal name of each owner or registrant, plus a mailing address if different
- The entity type: individual, married couple, general partnership, corporation, LLC, trust, or other structure
- The date the business first began operating under the fictitious name
You can list multiple businesses on one statement only if they share the same address and the same ownership. Two businesses at different locations need separate filings.
If You Work From Home
The principal business address becomes a public record. For a home-based business, that means your home address will be publicly searchable if you list it on the form. The California Secretary of State acknowledges that commercial mail-receiving services and virtual office providers exist specifically to give business owners a street address they can use instead.4California Secretary of State. FAQs – Personal Information in Public Filings Set that up before you file.
Where and How to File
File with the county clerk in the county where your principal place of business is physically located.2California Legislative Information. California Code BPC – Fictitious Business Names If you work across several counties, you only have to file in the one with your principal location, though you may file in others if you choose. Businesses with no California location file with the Clerk of Sacramento County.5California Legislative Information. California Code BPC 17915 – Filing Location
Submit the signed statement with one copy, a valid photo ID, and the filing fee. Counties accept filings in person, by mail, or through an online portal, depending on the county.
Fees vary. Most counties charge $26 to $55 for a single business name with one owner, with a small additional charge, usually $5 to $7, for each extra name or owner on the same statement. The clerk endorses and returns your copy with the file number, filing date, and expiration date. Keep that endorsed copy. You’ll need it for the newspaper and for opening business bank accounts.
Publishing in a Newspaper
Within 45 days of filing, you have to publish the statement in a newspaper of general circulation in the county where you filed. The notice runs once a week for four consecutive weeks.6California Legislative Information. California Code BPC 17917 – Publication of Fictitious Business Name Statement Pick a paper that actually circulates where your business operates. Most adjudicated newspapers charge $35 to $50 for the full four-week run.
After the final run, the newspaper gives you an Affidavit of Publication. File that affidavit with the county clerk within 45 days of the last publication date. Until the affidavit is on file, your registration isn’t complete.
What a Missed Filing Costs You
The penalty is immediate and practical. If you haven’t properly filed and published, you cannot bring a lawsuit on any contract made under the fictitious business name in any California court.1California Legislative Information. California Code BPC 17918 – Effect of Failure to File and Publish A customer who stiffs you on an invoice, a tenant breaking a lease signed under the business name, anyone with an unpaid balance owed to the name — all of them have a built-in defense until you clean up the registration. The bar applies to you and to anyone you assign the business to.
It isn’t permanent. Once you complete the filing and publication properly, you regain standing to sue. But the delay can be fatal to a time-sensitive claim, and no business that relies on enforceable contracts should treat this step as optional.
Renewing Every Five Years
An FBN statement expires five years from the date you filed it with the county clerk.7California Legislative Information. California Code BPC 17920 – Expiration of Fictitious Business Name Statement Mark the date now. The renewal catches people off guard.
If you refile within 40 days of expiration and nothing on the statement has changed, you can skip the newspaper publication. Submit the new statement and pay the filing fee.6California Legislative Information. California Code BPC 17917 – Publication of Fictitious Business Name Statement Miss that 40-day window and the refiling counts as a brand-new registration, with the full four-week publication required all over again.
If Something Changes Mid-Term
Your statement automatically expires 40 days after any change in the facts on it. A new owner, a different business address, or a change to the business name all trigger expiration. A change in a registered owner’s residence address, by itself, does not.7California Legislative Information. California Code BPC 17920 – Expiration of Fictitious Business Name Statement When you file a new statement to reflect a change, you go through the full publication process again.
Ending Use of a Fictitious Name
When you stop using a fictitious business name, file a Statement of Abandonment with the same county clerk that handled the original filing.8California Legislative Information. California Code BPC 17922 – Statement of Abandonment of Use of Fictitious Business Name The abandonment statement names the fictitious business, lists the principal business address, references the original filing date and file number, and gives the names and mailing addresses of all registrants.
The abandonment statement goes through the same four-week newspaper publication and affidavit filing as the original FBN. Only the content of the form is different.
A Fictitious Business Name Is Not Trademark Protection
Registering an FBN does not give you exclusive rights to the name. Not in your county, not statewide, not nationally. Another business can register the identical name in a different California county, and the FBN system does nothing to stop it.
The California Secretary of State doesn’t check FBN filings when evaluating whether a proposed entity name is available. It only compares proposed names against other entities of the same type already registered at the state level.9California Secretary of State. Name Reservations Someone could form a corporation using the exact name on your FBN, and the state would approve it.
If the name itself matters to your brand, you need a trademark. Federal registration through the U.S. Patent and Trademark Office covers you nationally; California state trademark registration covers you in-state. The FBN is a transparency tool that tells the public who stands behind a business name. It is not a claim of ownership over the name.
