California requires any business operating under a name different from its legal name to file what is called a fictitious business name—also known as a “DBA” or “Doing Business As” name. This requirement exists to protect the public by making sure everyone knows who really owns a business. Approximately 95 percent of new small businesses in California need to file this paperwork. This article explains exactly when you need a fictitious business name, how to file one, what mistakes to avoid, and answers to questions you might have.

The Core Problem: Identity and Trust
California businesses must operate with transparency. When someone does business with you, they need to know who they’re actually working with. For years, California had no way to track this information. Business owners could hide their identities, make deals under fake names, and then disappear without paying bills or fixing problems. The public had no protection.
<ins>California Business and Professions Code Section 17910 defines the requirement</ins> was created to solve this problem. This law says that anyone running a for-profit business under a name that is not their legal name or their company’s official name must file paperwork with the county. The consequence of not filing is serious—your business cannot file lawsuits to collect money owed to you until you comply with the filing rules.
Think of it this way: if you operate your business as “Sam’s Pizza Place” but your real name is Samuel Richardson, the court will not let you sue a customer who refuses to pay for a large order until you file your fictitious business name statement.
What Is a Fictitious Business Name?
A fictitious business name is any name your business uses that is not your legal name. For different types of business owners, this means different things.
For a sole proprietor (one person): Your legal name is your personal name. Any business name you use that doesn’t include your full last name is fictitious. For example, if your name is Michael Chen, “Chen’s Auto Repair” might be okay, but “Mike’s Auto Repair” or “Prime Auto Repair” would be fictitious. Additionally, any name that suggests other owners are involved, like “Chen & Sons” or “Chen and Associates,” is fictitious even if it includes your last name.
For a partnership (two or more people): Your legal name is the last names of all the partners. If you are partners with John Smith and Karen Lee, your legal name would include both “Smith” and “Lee.” Any other business name is fictitious. So “Smith Lee Financial Services” is okay, but “Premier Financial Services” is fictitious.
For a corporation or LLC (a formal business entity): Your legal name is exactly what appears on your formation documents filed with the California Secretary of State. If your LLC is called “Tech Solutions LLC,” any other name is fictitious. So if you wanted to operate a second business called “Tech Support Services,” that would require a fictitious business name filing.
Three Popular Scenarios and What You Must Do
Scenario 1: Solo Business Owner Using a Brand Name
| Situation | What Happens |
|---|---|
| Jessica owns a consulting business. Her full legal name is Jessica Marie Wu. She wants to operate under the name “Wu’s Business Solutions.” | This is a fictitious business name because it does not include her full legal name, just her last name. She must file within 40 days of starting her business. |
| Jessica owns the same consulting business and wants to operate as “Wu Consulting.” | This is a fictitious business name. Even though “Wu” is her last name, it is shortened and the full legal name is not shown. She must file. |
| Jessica opens a business and operates as “Jessica Marie Wu Consulting.” | This is her legal name, so no fictitious business name filing is required. |
Scenario 2: Partnership Expanding into Multiple Brands
| Situation | What Happens |
|---|---|
| Two partners, David Foster and Michelle Parks, start a construction company. They use the name “Foster Parks Construction Inc.” | Since both partner last names are included, no fictitious business name is required for this name. However, if they want to also operate “Emergency Repairs Co.” under the same partnership, they must file a fictitious business name for “Emergency Repairs Co.” and pay a separate fee. |
| The same partners want to use “Foster & Parks” as their name. | The words “Foster & Parks” suggest other unnamed partners might exist, so this is fictitious. They must file even though their names are included. |
Scenario 3: Corporation Operating Multiple Businesses
| Situation | What Happens |
|---|---|
| ABC Marketing Corp. (the legal name registered with the state) wants to run three separate marketing firms under three different brand names: “Social Media Stars,” “Content King,” and “Digital Boost.” | The legal entity name is “ABC Marketing Corp.” Each of the three brand names is fictitious. The company must file three separate fictitious business name statements, pay three separate fees, and publish three separate newspaper notices. |
| The same ABC Marketing Corp. wants to operate under a slightly different name: “ABC Marketing Solutions Corp.” | This name is different from the legal name registered with the state, so it is fictitious and must be filed. |
When You Do NOT Need a Fictitious Business Name
Not every business needs to file. Understanding when you don’t need to file saves you money and time.
Nonprofit corporations do not need to file a fictitious business name. California Business and Professions Code Section 19711 says nonprofits are exempt from this requirement. This includes churches, charities, educational foundations, and other nonprofits that do not operate for profit.
Unincorporated real estate investment trusts do not need to file. California Business and Professions Code Section 19712 exempts these specific trusts from the fictitious business name requirement.
Sole proprietors using their full legal last name do not need to file a fictitious business name if they operate under their legal name. For example, if your name is Robert Johnson and you operate “Robert Johnson’s Plumbing,” no filing is required. However, if you want to call yourself “Bob’s Plumbing” or “Johnson Plumbing Services,” you must file.
Corporations and LLCs using their exact legal name do not need to file. If you formed an LLC called “Creative Design Solutions LLC” and operate only under that exact name, you don’t need a fictitious business name statement. The moment you operate under any other name—even a shortened version—you must file.
The Complete Filing Process: Step-by-Step
Filing a fictitious business name involves multiple steps, and each one has specific requirements and deadlines.
Step 1: File Within 40 Days of Starting Business
California law says you have exactly 40 days from the day you begin conducting business to file your fictitious business name statement. If you start operating on January 1, you must file by February 10. If you miss this deadline and someone sues you for money, you cannot use the courts until you file the statement and complete publication. There are no extensions.
The filing must happen in the county where your principal place of business is located. If your office is in Los Angeles County, you file with the Los Angeles County Clerk. If you have no location in California but you’re doing business here, you file in Sacramento County.
Step 2: Pay the Filing Fee
Fees vary by county, but most charge between $25 and $60 for the first business name. Each additional business name on the same statement costs between $2 and $7 more. Contra Costa County charges specific fees for one name and $7 for each additional name. Alameda County charges $40 for one name and $7 for each additional. These are just examples—always check your specific county’s website for exact fees.
Step 3: Complete the Fictitious Business Name Statement Form
The statement must include specific information. California Business and Professions Code Section 17913 requires the form to show your fictitious business name, the street address of where you do business, the full name and home or business address of every owner, the type of business (individual, partnership, corporation, LLC), and the date you started or will start using the name.
You cannot use a post office box—you must provide a physical street address. If you are a corporation, an officer of the corporation must sign the form and include their title. If you are an LLC, a member or manager must sign it.
Step 4: Publish in a Local Newspaper for Four Weeks
This is the part that confuses many business owners. Within 30 days after filing your statement, you must publish it in a newspaper of general circulation in the county where you filed. The notice must appear once a week for four consecutive weeks. This means four separate publications in four different weeks.
For example, if you file on January 15, you must start publishing by February 14. Your publication dates might be February 22, March 1, March 8, and March 15. You cannot compress this into fewer weeks. The law specifically says “four consecutive weeks.”
The newspaper must be a “newspaper of general circulation”—not a tiny community flyer or an online-only publication. Most counties maintain a list of approved newspapers. In Sacramento County approved newspapers include the Sacramento Bee and several community newspapers. Your county clerk can give you the exact list.
Step 5: File Your Affidavit of Publication
Within 30 days after your final publication appears, you must file an affidavit of publication with the county clerk. This is the newspaper’s official proof that they published your notice. Most newspapers handle this automatically and send it directly to the county clerk. However, you should confirm with the newspaper that they will file this for you. If they don’t, you must do it yourself.
If you miss this step, your fictitious business name registration is not complete, and you have no legal protection.
Step 6: Renew Every Five Years
Your fictitious business name statement expires five years from the date you filed it. If you file on January 15, 2025, it expires on January 15, 2030. You must file a new statement before that date to keep doing business under that name.
If you renew within 40 days of the expiration date and nothing about your business has changed (same owners, same address, same name), you may not need to publish again. However, if you renew after 40 days have passed or if any information changed, you must go through the full publication process again.
Who Must File: The Specific Rules
Sole proprietors must file if their business name does not include their complete last name or if the name suggests other owners are involved. A name like “Tom’s Plumbing” requires a filing if Tom’s last name is not “Tom.” A name like “Johnson & Son” requires a filing even if the owner’s name is Johnson, because the name implies a second owner.
Partnerships must file if the name does not include all partners’ last names or if the name suggests additional unnamed partners. “Smith Johnson Accounting” requires a filing if there are more than two partners or if other partners exist. “Smith & Associates” requires a filing because it suggests other business associates.
Corporations and LLCs must file if they operate under any name other than the exact legal name on their formation documents. If your corporation is “Premier Solutions Inc.” and you want to operate as “Premier,” you must file.
Out-of-state businesses doing business in California must file if they don’t operate under their legal registered name. An out-of-state LLC named “Tech Innovations Holdings” that wants to do business in California as “Tech Support Services” must file with the Sacramento County Clerk.
The Real Consequences of Not Filing
Many business owners think the fictitious business name requirement is optional. It is not. There are serious legal consequences.
You cannot sue in court. California Business and Professions Code Section 17918 states that if you operate under an unregistered fictitious business name, you cannot file any lawsuit to collect money owed to you until you comply with all filing and publication requirements. Imagine you perform $50,000 in consulting work for a client under your fictitious business name. The client refuses to pay. You try to sue. The court throws out your case because you never filed your fictitious business name statement. You must then file the statement, wait for publication to complete, and then you can file your lawsuit. Meanwhile, months have passed and the client might have disappeared.
Personal liability problems. An officer or manager who signs a contract on behalf of an entity using an unregistered fictitious business name can face personal liability. If the person signing the contract fails to disclose that they are acting on behalf of a business, they might be personally responsible for the contract.
Misdemeanor charges. California Business and Professions Code Section 17930 states that anyone who files a fictitious business name statement knowing it contains false information is guilty of a misdemeanor punishable by a fine up to $1,000.
Loss of privacy. Your home address appears on the public filing unless you have a business address. This exposes your personal location to anyone who searches the records.
Do’s and Don’ts
DO file your statement within 40 days of starting business. The deadline is hard. Missing it causes serious problems later when you want to sue someone.
DO use an actual street address, not a post office box. The county will reject the form if you list only a PO box.
DO confirm the newspaper will file the affidavit of publication for you. Don’t assume—call and verify they will send it to the county clerk within the deadline.
DO check your county’s fee schedule before filing. Fees vary significantly by county, and you might be surprised by the cost.
DO publish in a newspaper of general circulation. Using the wrong publication wastes money and does not satisfy the law.
DON’T assume your business name is unique. Search the county records before filing. If another business is already using your name, your application might be rejected or delayed.
DON’T miss the 30-day deadline to file your affidavit of publication. Missing this deadline means your filing is incomplete, even though you paid the fee and published the notice.
DON’T change your business information and keep operating under the old filing. If you move to a new address or add a new owner, you must file a new statement within 90 days.
DON’T use corporate identifiers in your fictitious name if you’re not a corporation. A sole proprietor cannot use “Sam’s Auto Repair Inc.” unless they actually incorporated.
DON’T delay in renewing your statement after five years. Operating under an expired fictitious business name is the same as operating with no filing at all.
DON’T create the same fictitious business name in multiple counties expecting it to be protected statewide. Fictitious business name protection only applies in the county where you file.
Pros and Cons of Filing a Fictitious Business Name
| Advantage | Why This Matters |
|---|---|
| Establish legal protection for contracts | With a filed and published statement, you can enforce contracts in court. Without it, the court will reject your lawsuits. |
| Gain privacy | Your personal name stays separate from your business name. Customers see “Prime Auto Repair” not “Michael Chen’s Auto Repair.” |
| Open a business bank account | Most banks require a copy of your fictitious business name statement to open a business account in your DBA name. |
| Use a memorable brand name | Instead of using your legal name, you can choose a name customers will remember and understand what you do. |
| Operate multiple businesses under one entity | A corporation can file multiple fictitious business names for different product lines or locations. |
| Disadvantage | Why This Matters |
|---|---|
| Newspaper publication costs money | Depending on the newspaper and county, publication costs between $35 and $300 or more, which is a burden for startup businesses. |
| Publication takes time | You must wait four weeks for publication to finish before your filing is complete. If you need to operate faster, this delays you. |
| No legal liability protection | A fictitious business name does not shield your personal assets from lawsuits. Only an LLC or corporation provides liability protection. |
| Does not protect your name | Filing a fictitious business name does not stop someone else in a different county from using the same name. Trademark registration does that. |
| Renewal is required every five years | Unlike a trademark which lasts longer, your fictitious business name expires and must be renewed with fees and publication all over again. |
| County-level only | Your fictitious business name is registered in one county. If you expand to another county, you must file again there. |
Common Mistakes to Avoid
Mistake 1: Thinking you need an EIN (Employer Identification Number) for your fictitious business name
A fictitious business name and an EIN are completely different things. A fictitious business name is just a registration of what you call yourself. An EIN is a tax identification number. You do not need an EIN just to file a fictitious business name. You need an EIN only if you form a corporation or LLC, or if you hire employees. For a sole proprietor operating alone with no employees, you don’t need an EIN and can use your Social Security Number for taxes.
Mistake 2: Assuming publication in any newspaper counts
It does not. The newspaper must be a “newspaper of general circulation” approved by the county. A small community newsletter or a free advertising magazine will not satisfy the requirement. The county clerk maintains a list of approved newspapers. Always check this list before arranging publication.
Mistake 3: Filing in the wrong county
You must file in the county where your principal place of business is located. If your office is in San Diego County but you do some work in Los Angeles County, you still file in San Diego County. You can file in additional counties if you do substantial business there, but you must file in the county of your main location.
Mistake 4: Not updating the filing when your information changes
If you move your office, add a new partner, or change any information on your original statement, you must file a new statement within 90 days. Continuing to operate under the old information violates the law.
Mistake 5: Waiting too long to renew
When your five-year term is about to end, start the renewal process early. If you wait until after the expiration date and then wait to publish, you might miss deadlines and lose your legal standing.
Mistake 6: Operating under a name before filing
The law says you have 40 days from when you start operating to file. If you start on January 1 but don’t file until February 45, you’ve violated the law. Operate under your legal name first, then file your fictitious name immediately.
Mistake 7: Using the same statement for multiple unrelated businesses at different locations
Each fictitious business name can include multiple business names operating at the same address under the same ownership. However, if you operate different businesses at different addresses or under different ownership, you need separate filings.

Can You Sue in Court? All four structure types can sue in court, though the process varies. For DBAs and sole proprietorships, you must be in compliance with filing requirements to bring lawsuits. For LLCs and corporations, the entity itself sues.
Personal Assets Protected? Only LLCs and corporations protect personal assets. DBAs and sole proprietorships offer no liability protection. Your personal property is at risk if the business gets sued.
The Legal Foundation
California Business and Professions Code Section 17910 requires that every person who regularly operates a for-profit business under a fictitious business name must file a statement within 40 days of starting business. Section 17913 specifies exact information required on the form and how it must be presented. Section 17915 explains where to file based on your business location. Section 17917 details the newspaper publication requirement—the notice must be published once a week for four consecutive weeks in a newspaper of general circulation.
Section 17918 provides the main enforcement mechanism. It says that if you operate under a fictitious business name without filing, you cannot maintain any lawsuit to recover money on account of any contract you made under that name until you comply with all filing and publication requirements. This applies even if the other party breached the contract first.
Section 17924 covers renewal requirements. Your statement expires five years after filing. Section 17930 creates criminal penalties—filing false information is a misdemeanor punishable by a fine up to $1,000.
California Business and Professions Code Section 14411 is also critical. This section says that filing a fictitious business name statement creates a rebuttable presumption that you have the exclusive right to use that name in your county, if you were the first to file. This presumption is helpful in disputes with competitors who try to use the same name.
Important Court Rulings
Courts have interpreted the fictitious business name law in several important ways.
In Villareal v. LAD-T, LLC (2022), a company tried to enforce an arbitration agreement under an unregistered fictitious business name. The court found that the company had failed to comply with the filing requirements and initially barred them from enforcing contracts. The court later allowed the company to compel arbitration, but only after finding the company had not intentionally acted in bad faith. This case shows that courts take the filing requirement seriously and will bar contract enforcement against businesses that don’t comply.
In another case, Savea v. YRC, the court found that a company that properly filed its fictitious business name was entitled to list that name on wage statements provided to employees. The court noted that because the company had a valid fictitious business name statement on file, using that name on official documents was legally correct.
These cases establish that courts will enforce the filing requirement strictly. Courts do not forgive missed deadlines or incomplete filings.
Critical Points About Specific Situations
Partnership Dissolution:
If you are dissolving a partnership and want to stop using a fictitious business name, you must file a “Statement of Withdrawal of Assumed Name for Partnership.” This tells the county that the partnership is no longer using that name. The same publication requirements apply—you must publish in a newspaper once a week for four consecutive weeks.
Adding or Removing Owners:
If a new partner joins your business or an existing partner leaves, you must file a new fictitious business name statement within 90 days. The new statement should list all current owners. This counts as a change in facts that triggers new publication requirements.
Business Address Changes:
If you move your office to a new address, you must file a new statement within 90 days. Again, this triggers the publication requirement. You cannot simply call the county and tell them your address changed—you must file a new complete statement.
Operating in Multiple Counties:
If you do business in more than one county, you can file in additional counties beyond your principal place of business. However, you are required to file in the county of your principal location. Filing in additional counties is optional but recommended if you have customers or employees in those counties and want the legal protection that the filing provides.
Professional Businesses (Doctors, Lawyers, Engineers):
Professionals must follow different rules in some cases. For example, California Business and Professions Code Section 2285 requires health care providers and certain licensed professionals to obtain a special “fictitious name permit” in addition to or instead of a regular fictitious business name. If you are a physician, dentist, lawyer, or engineer, you must research your specific profession’s requirements.
The Timeline from Start to Legal Operation
Understanding the timeline helps you plan. Here is what happens from the moment you start your business:
Day 1: You begin operating your business. At this point, you should start documenting when you opened. Keep emails, receipts, or other proof of the date you started serving customers or clients.
Days 1-40: You have this window to file your fictitious business name statement with the county clerk. You can file anytime during this period. Many business owners file in the first two weeks to get ahead of the deadline.
Day of Filing to Day 30: The county clerk processes your filing. You pay your fee and receive a filed copy. Keep this filed copy—you will need it to arrange newspaper publication.
By Day 30 after filing: You must arrange for publication in a newspaper. You contact the newspaper and submit your statement. The newspaper will tell you when they can start publication.
Week 1, 2, 3, 4: Your notice appears in the newspaper once per week for four consecutive weeks. Mark these dates on your calendar because they determine when your filing is complete.
Within 30 days after the final publication: The newspaper files the affidavit of publication with the county clerk. This is usually automatic, but you should verify by calling the county clerk’s office after the deadline has passed.
Publication Complete: Your fictitious business name is now fully registered and legally valid. You can now enforce contracts in court and open business bank accounts under your DBA name.
Year 1-5: You operate under your fictitious business name. During this time, you can renew if information changes, or you can wait until near the five-year expiration to renew if nothing has changed.
Around Year 5: You should begin renewal proceedings to avoid any gap in your filing. Start the renewal process at least two months before expiration.
After Year 5: If you have not renewed, your statement has expired and you no longer have legal protection. Operating without a valid filing puts you in violation of state law.
The entire process typically takes 5-6 weeks from filing to completion.
Fictitious Business Names vs. Trademarks
Many business owners confuse these. A fictitious business name statement and a trademark are not the same.
A fictitious business name is a county-level registration that tells the public who owns the business. It provides some local protection and allows you to sue in court. It costs $25-$60 and applies only in the county where you file.
A trademark is a federal or state protection that prevents anyone from using your business name anywhere in the country (if federal) or state (if state). It costs more to file but provides stronger protection. Registering a trademark does not replace the need to file a fictitious business name.
You can and should do both if your business name is important to your brand. Filing a trademark at the federal level takes several months and costs $250-$400 or more, but it protects your name everywhere. Filing a state trademark is faster and cheaper but only protects your name within California.
Why Businesses Ignore the Filing Requirement and Regret It
Many new business owners skip the fictitious business name filing because they think it’s optional or too complicated. Here are the real problems that happen when they skip this step.
A consulting business called “Peak Strategies” operated for two years without filing a fictitious business name. The owner thought it was unnecessary because her clients knew her personally. One client refused to pay a $75,000 project invoice. When the owner tried to sue, the court dismissed the case. The court said she could not sue under “Peak Strategies” without a filing. She had to file the statement, wait for publication to finish, and then re-file her lawsuit. Six months had passed, and the client had closed their business and disappeared. The owner never collected the money.
Another example: A small construction company operated under the name “Expert Home Repair” without a fictitious business name filing. A customer hired them to remodel a kitchen and paid $40,000 upfront. The company took the money and never showed up to start the work. The homeowner tried to get their money back but couldn’t sue effectively because the company had no registered fictitious business name. Without legal clarity about who owned the business, the homeowner’s lawyer struggled to identify who to sue.
A third scenario involved a freelance writer who set up a business called “Wordsmith Writing Services” without filing. She was unable to open a business bank account under her DBA name. Instead, she had to deposit all client payments into her personal checking account. This created tax problems because the IRS couldn’t easily separate her business income from her personal income. During an audit, she owed back taxes and penalties on income she did report.
These are not theoretical problems. They happen to real business owners every year.
What to Expect: The Costs Involved
Understanding all the costs helps you budget for your filing. The filing fee is just one part of your total expense.
The filing fee to the county clerk ranges from $25 to $60 depending on your county. If you file multiple business names on one statement, each additional name costs $2 to $7.
The newspaper publication cost is separate and often the most expensive part. The cost depends on which newspaper you choose and how many words are in your notice. Most newspapers charge between $35 and $300 for the four-week publication requirement. A small community newspaper might charge $50, while a larger daily newspaper might charge $200.
Some counties offer alternative filing methods. Sacramento County and several others allow online filing, which doesn’t reduce fees but makes the process faster. Some counties accept mail filing but not online filing.
If you need to hire a lawyer to help with the filing, expect to pay $200 to $500 for legal assistance. Many business owners skip this and do the filing themselves to save money.
Total cost estimate: $100 to $400 for the complete filing, depending on your county and newspaper choice.
Frequently Asked Questions
Must I file a fictitious business name if my business name includes my legal last name?
No. Not necessarily. If your business name is exactly your legal name (for example, “Jennifer Wu Consulting” and your legal name is Jennifer Wu), you do not need a fictitious business name filing. However, if your name is “Jennifer Marie Wu” and you operate as “Jennifer Wu Consulting,” check carefully. The key is whether the name could be confused with a different legal name. When in doubt, contact your county clerk and ask for guidance.
Can I file my fictitious business name online?
Yes. Many California counties accept online filing through their clerk website. Los Angeles, San Diego, and Sacramento Counties all offer online filing. However, some counties still require in-person or mailed filing. Check your specific county’s website to see what methods they accept.
What happens if I operate under a fictitious business name without filing?
Yes, the court will dismiss your lawsuits. You cannot enforce contracts, collect debts, or recover money through the courts until you file and publish. You also face potential misdemeanor charges if you knowingly file false information.
How much does it cost to file a fictitious business name?
No. The filing fee varies by county but typically ranges from $25 to $60 for the first business name. Additional names cost $2-$7 each. Plus, you must pay to publish in a newspaper, which costs $35-$300 depending on the newspaper and county.
Can I file multiple business names on one statement?
Yes. If you operate multiple businesses at the same address under the same ownership, you can list multiple business names on one statement. Each additional name costs extra, and you must publish all names together, but you file and pay only once.
Do I need a fictitious business name if I have an LLC?
No, not for the LLC’s legal name. If your LLC is called “Premier Solutions LLC” and you operate only under that name, you need no fictitious business name. If you operate under a different name, like “Premier Support Services,” then you must file a fictitious business name for that additional name.
How long does the publication process take?
It takes at least five weeks. The publication must appear once per week for four consecutive weeks, plus you need time to arrange the publication and time for the newspaper to file the affidavit. Plan for 5-6 weeks total from filing to final completion.
Can I start using my fictional business name before my filing is complete?
Yes. You can start using the name immediately, but you must complete the filing and publication process within the required timeframes. However, you cannot sue in court to enforce contracts under that name until the publication is finished. It is best to get the whole process done quickly.
What is an affidavit of publication?
It’s proof from the newspaper that they published your notice. The newspaper provides this document after publication is complete. You (or the newspaper) must file this with the county clerk within 30 days of the final publication. Without this affidavit, your filing is incomplete.
If I renew my fictitious business name, do I have to publish again?
Not always. If you renew within 40 days after your statement expires and nothing has changed (same owners, same address, same name), you don’t have to publish again. If you renew after 40 days have passed or if information changed, you must publish again.
What if another business in a different county uses the same name as my fictitious business name?
That’s allowed. Fictitious business name protection applies only within your county. Another business in Fresno County can use the same name as your business in Los Angeles County. To protect your name statewide or nationally, you need to register a trademark, not just file a fictitious business name.
Do I need a fictitious business name if I am a nonprofit?
No. Nonprofit corporations are exempt from the fictitious business name requirement. This is true even if the nonprofit operates under a name different from its legal name. However, nonprofits should still consider registering a trademark to protect their name.
Can I use a post office box as my business address on the fictitious business name form?
No. You must provide a physical street address. A post office box is not acceptable. If you work from home, you must list your home address unless you rent a commercial office space.
What happens if I move my business to a different county?
You must file a new fictitious business name statement in the new county within 90 days of moving. The statement in your old county is still valid in that county, but you need a new filing in your new principal place of business county.
Can one person file multiple fictitious business names in different counties?
Yes. You can file as many fictitious business names as you want in as many counties as you conduct business. Each filing requires its own fee and publication. There is no limit to the number of filings.
Does a fictitious business name expire if I stop using it?
No. Your fictitious business name statement expires after five years whether you use it or not. If you want to stop using a name, you can file a “Statement of Abandonment” with the county to formally end the registration early. However, you must still publish notice of the abandonment.
