Fictitious business name in San Diego County
San Diego County requires a fictitious business name statement within 40 days of first doing business under the name. The County Clerk's filing fee is $54 for the first name and registrant, and the statement lasts five years.
The 40-day deadline
Business and Professions Code section 17910 requires a statement no later than 40 days after the registrant starts to transact business under the name. Anyone who regularly does business for profit under a fictitious name in San Diego County files with the County Clerk. Once registered, the statement is effective for five years.
Section 17900 gives the reason for the filing. It makes public the identities of the people behind the name. It confers no right or advantage on a business that fails to comply.
What counts as a fictitious name
The county gives its own pair of examples. "Jonathan Garcia Catering" is not a fictitious business name, and "Garcia and Company Catering" is. A name implies additional owners when it carries words such as Company, & Son, & Associates or Brothers. Section 17900 excludes words that merely describe the business.
For an LLC or corporation, the county treats any name other than the legal name on file with the Secretary of State as fictitious. An LLC trading under a shortened version of its legal name therefore needs its own statement. A person naming a sole proprietorship starts from the surname test instead.
Fees and filing routes
The county's fee schedule starts at $54 for the first name and owner and adds smaller charges for extras. Filing fees are not refunded once the statement is filed.
| Item | County fee |
|---|---|
| First business name and one registrant | $54 |
| Each additional owner, except a married couple | $5 |
| Each additional name at the same location | $5 |
| Online filing service fee | 2.19% |
| In-person card payment, extra | $2.50 |
| Statement of Abandonment | $48 |
| Search by mail through the clerk | $8 |
Online filing is the county's recommended route, and the whole filing can be finished online without printing or visiting an office. In person, filers can go to downtown San Diego, Chula Vista, Santee or San Marcos with no appointment. The Kearny Mesa office does not take these filings.
A mailed filing needs a check or money order and the original statement with a wet-ink signature. It needs no copy of an ID and no notary acknowledgement.
Completing the statement
The statement is filed with the clerk of the county where the principal place of business sits. A filer with no place of business in California files in Sacramento County. Post office boxes and mailbox numbers are not accepted as the principal place of business, though either works as the mailing address.
Only businesses at the same address and under the same ownership can share one statement. An LLC's statement is signed by a manager or officer. The form asks for the date business began, which cannot be a future date, and N/A is entered if business has not started.
Section 17913 makes it a misdemeanor, with a fine up to $1,000, to declare as true something the registrant knows is false. In-person filers show government-issued photo ID, and an authorized agent shows the agent's own ID.
Publishing the notice
Section 17917 requires publication within 45 days after filing, in a newspaper of general circulation. The paper should circulate where the business operates. The notice runs once a week for four consecutive weeks. It is a legal notice and not a business advertisement.
The county lists adjudicated newspapers as a courtesy and endorses none of them. Papers may not publish right away, so the clerk advises contacting one early. A missed 45-day deadline makes the statement expire automatically, and the law allows no extensions.
After the fourth notice, the Proof of Publication goes to the County Clerk within 45 days. Filing it is the registrant's job, although some newspapers file it for an added fee.
A renewal skips publication only when nothing changed and it is filed within 40 days after expiration. A first filing, a change, a statement that lapsed longer ago and an abandonment all require publication.
Searching records before filing
The registrant, not the county, is responsible for checking the name. The FBN Records Search shows whether a name is registered and who owns it. The clerk can also search by mail for $8. Send the exact name and allow 7 to 10 business days.
The clerk keeps these names as a central depository and neither approves nor disapproves one. It accepts no responsibility for omissions, similarities or duplications. Names are filed only in the county where the business is located, so a San Diego search covers no other county. California has no statewide registry.
Registration does not guarantee exclusive use. The statement form adds that filing does not authorize a name that violates another party's federal, state or common law rights. The two businesses sharing a name guide covers those limits, and the business name search checks state registers.
Changes, endings and copies
Once filed, a statement cannot be changed or corrected. A change requires a new filing with new publication, and a statement expires 40 days after any change other than a residence address.
A registrant who stops using the name within five years of filing files a Statement of Abandonment under section 17922, which is also published. An expired statement needs none. A partner who leaves a partnership can file a Statement of Withdrawal, and the statement stays in force.
Banks frequently ask for a certified copy to open an account. A copy costs $2 for the first page and $0.05 for each additional page, plus $1 for certification. Online orders are printed the next business day and arrive in 3 to 5 business days.
