Step-by-Step: Sue a Business in California
Follow these 6 steps to properly sue a company in California small claims court. Each step includes exactly what to do and common pitfalls to avoid.
Look Up the Business Entity
Before you can sue a company, you need its exact legal name. A misspelled or incorrect name can get your case dismissed.
- Go to the California Secretary of State's bizfile database (bizfileonline.sos.ca.gov)
- Search by the company's name as you know it
- Note the exact legal name (e.g., "ABC Services, LLC" vs "ABC Services Inc.")
- Check the entity status - it must be "Active" to be sued
- Record the entity number for your records
- For sole proprietors, check the county's fictitious business name (DBA) filings
Pro Tip
If the company is a sole proprietor or DBA, you must sue the individual owner by their legal name, not the business name alone.
Find the Registered Agent for Service
Every California corporation, LLC, and LP must have a designated agent for service of process. This is who you'll serve with your lawsuit.
- The registered agent is listed in the Secretary of State records
- It can be a person (officer, director) or a registered agent service company
- Common agent services: CT Corporation, CSC, Registered Agent Inc.
- Note the agent's full name and physical street address (not a P.O. Box)
- If the agent has resigned or the address is invalid, you may serve the Secretary of State directly (CCP § 416.10)
Pro Tip
Large national companies often use professional registered agent services. These agents are experienced with receiving legal documents and will promptly forward them.
Choose the Correct Venue (County)
Filing in the wrong county can delay or dismiss your case. California law provides several options for where to file against a business.
- Where the company's principal place of business is located in California
- Where the contract was signed or was to be performed
- Where the injury or property damage occurred
- Where the company has a branch office involved in the transaction
- For out-of-state companies doing business in CA: where they transact business or where the cause of action arose
Pro Tip
If a company has multiple California locations, choose the venue most convenient for you that still meets the legal requirements.
Complete and File Form SC-100
Fill out the Plaintiff's Claim form carefully, using the company's exact legal name as it appears in Secretary of State records.
- Use the company's full legal name as the defendant (e.g., "XYZ Corp., a California corporation")
- Include the registered agent's address as the defendant's address
- Clearly describe the dispute: what the company did or failed to do
- State the exact amount you're claiming (up to $12,500)
- Explain what you did to try to resolve the issue before filing (demand letters, calls)
- Pay the filing fee: $30 (under $1,500), $50 ($1,500–$5,000), $75 ($5,000–$10,000), or $100 (over $10,000)
Pro Tip
Always send a written demand letter to the company before filing. Judges look favorably on plaintiffs who tried to resolve the dispute first.
Serve the Company Properly
Improper service is the #1 reason cases against companies get dismissed. Follow California's rules exactly.
- Personal service on the registered agent is the most reliable method
- Have someone 18+ (not you) hand-deliver the papers to the agent
- Alternatively, use a professional process server ($40–$75)
- Certified mail with return receipt is allowed but less reliable for businesses
- Service must be completed at least 15 days before the hearing (or 20 days if served outside the county)
- The person who serves must complete Form SC-104 (Proof of Service)
Pro Tip
Professional process servers are recommended for business defendants - they know how to navigate corporate offices and document service properly.
Prepare and Present Your Case
When suing a company, strong documentation is essential. Judges expect organized evidence and a clear narrative.
- Bring the contract, invoice, or agreement (if one exists)
- Print all relevant emails, texts, and written communications
- Include photos of defective products or property damage
- Bring receipts showing what you paid and what you're owed
- Prepare a written timeline of events
- Calculate your damages clearly (itemize every dollar)
- Bring 3 copies of everything: for you, the judge, and the defendant
Pro Tip
Companies often don't show up to small claims hearings, resulting in a default judgment in your favor. Be prepared either way.

Suing a Business in California Small Claims Court
When suing a company in California small claims court, one of the most critical steps is identifying the correct legal name of the business. You must name the defendant exactly as the business is registered - using a trade name, DBA, or abbreviated version can result in your case being dismissed or your judgment being unenforceable. For corporations and LLCs, search the California Secretary of State's business database at bizfileonline.sos.ca.gov to find the entity's exact registered name, status, and agent for service of process. For sole proprietorships and partnerships operating under a fictitious business name, check the county clerk's fictitious business name records in the county where the business operates.
You should also determine whether to name the business entity, the individual owner, or both. If you are dealing with a sole proprietorship, the owner is personally liable, so you should name both the business and the individual. For corporations and LLCs, the business entity is typically the proper defendant, and individual officers or members are shielded from personal liability unless they personally committed the wrongful act.
Finding Registered Agents and Serving Businesses
Every California corporation and LLC is required to designate an agent for service of process - this is the person or company authorized to receive legal documents on behalf of the business. You can find the registered agent's name and address through the Secretary of State's business search. Service must be made on the agent personally or, if the agent cannot be found, by serving the Secretary of State directly with the appropriate fee and paperwork. For businesses without a registered agent on file - which is common with suspended or dissolved entities - you may need to serve an officer, director, or general manager of the company. California Code of Civil Procedure Section 416.10 outlines the acceptable methods for serving a corporation, and Section 416.40 covers service on unincorporated associations. PettyLawsuit researches the correct entity name and registered agent for you, ensuring that service is properly directed and your case proceeds without delays.
What to Expect When a Business Defends Against Your Claim
Suing a company in California small claims court differs from suing an individual in several important ways. Businesses, particularly larger corporations and well-established LLCs, may send a knowledgeable employee, manager, or officer to represent them at the hearing. Unlike individuals, California corporations and LLCs are permitted to be represented by a non-attorney employee who is authorized to act on behalf of the business. This representative may come prepared with internal records, invoices, work orders, and other documentation to counter your claims. Do not assume that the business will fail to appear - while default judgments are common in small claims cases against businesses, many companies take these cases seriously and will mount a defense.
When a business contests your claim, the judge will want to hear both sides and examine the evidence. Businesses frequently raise defenses such as the plaintiff failed to mitigate damages, the services or products were delivered as agreed, the warranty had expired, or the plaintiff's own actions contributed to the loss. To counter these defenses, prepare detailed evidence showing exactly what was promised, what was delivered, and how the two differ. Written contracts, email confirmations, advertising materials, and photographs documenting defects or incomplete work are all powerful evidence. If the business made verbal promises that differed from a written contract, note the date, time, and names of employees who made those statements.
If you win a judgment against a company, collecting can sometimes be more straightforward than collecting from an individual. Businesses typically have bank accounts, accounts receivable, and physical assets that can be levied or garnished. If the company fails to pay the judgment voluntarily within thirty days, you can obtain a writ of execution from the court and have the sheriff levy the company's business bank account. You can also file a lien against the business's real property or, in some cases, pursue the personal assets of individual owners if the company was improperly operated or if the corporate veil can be pierced. PettyLawsuit provides guidance on post-judgment collection strategies to help ensure you actually receive the money you are owed.
