How to Serve Someone in Small Claims Court in California

You've filed your small claims case, paid the fee, and gotten a hearing date. Now you need to get the papers into the defendant's hands — and do it the right way, because improper service means the court can't hear your case. California has strict rules about who can serve, how they can serve, and when it must happen.

You Cannot Serve the Papers Yourself

This catches people off guard. Under CCP § 116.340, the plaintiff cannot personally deliver the court documents. Someone else — at least 18 years old and not named in the lawsuit — must do it. Your options:

• A friend or family member (free, but they must be willing to fill out the proof of service form)
• The county sheriff or marshal ($50 per defendant, covered by a fee waiver if you have one)
• A registered process server (typically $50–$150 depending on location and difficulty)
• The court clerk via certified mail ($15 per defendant, but only works if the defendant personally signs the postal receipt)

Personal Service

The most reliable method. The server walks up to the defendant, hands them a copy of Form SC-100, and tells them the papers are for a small claims case. Service is complete even if the defendant refuses to take the papers.

For in-county defendants, personal service must happen at least 15 calendar days before the hearing. Out-of-county defendants get an extra 5 days — service must happen at least 20 calendar days before the hearing.

Substituted Service

When the defendant dodges personal delivery, substituted service (CCP § 415.20) is the fallback. The server goes to the defendant's home or workplace and leaves the papers with an adult (at least 18) who lives at the home or appears to be in charge at the workplace. The server tells that person to give the papers to the defendant, then mails a second copy to the same address by first-class mail.

The catch: substituted service adds 10 calendar days to the service deadline because it's complete only 10 days after the mailing. That means the initial delivery must happen at least 25 calendar days before the hearing for in-county defendants, or 30 calendar days for out-of-county.

Certified Mail Through the Court Clerk

Ask the court clerk to mail your claim via certified mail with return receipt requested ($15 per defendant). This is the easiest method, but it fails if the defendant doesn't personally sign the green postal receipt card. If a family member signs, or the letter goes unclaimed, service is invalid and you'll need to try another method.

Serving a Corporation or LLC

Corporations and LLCs must be served through their designated Agent for Service of Process, listed in the California Secretary of State's bizfile records (bizfileonline.sos.ca.gov). You can also serve an officer, a managing agent, or a general manager of the company.

Use the same methods — personal or substituted service — but deliver the papers to the registered agent's address rather than the business's storefront. The agent exists precisely for this purpose.

File Proof of Service (Form SC-104)

After service is complete, the person who served the papers fills out Form SC-104 (Proof of Service) describing when, where, how, and on whom they served the documents. You file the completed form with the court clerk at least 5 court days before the hearing date.

Missing this deadline is one of the most common reasons cases get postponed. Mark the filing deadline on your calendar as soon as you get your hearing date.

The California small claims filing guide includes a service planner worksheet that calculates your deadlines backward from the hearing date, plus step-by-step instructions for each service method.
