How to Serve a California Small Claims Defendant

Proper service is essential—defective service means starting over or losing your case

Service: The Most Common Point of Failure

After filing your small claims case, you must legally notify the defendant. This is called "service of process." California law (CCP § 116.340) requires proper service—without it, the court cannot enter a judgment, even if you win.

I've seen countless cases dismissed or delayed because plaintiffs didn't serve correctly. The rules are strict but manageable if you follow them precisely.

Who Can Serve the Papers?

California law requires service by a neutral third party. You (the plaintiff) CANNOT serve your own papers.

Eligible Servers

Critical: If you serve the papers yourself, service is void. The court will reject it, and you'll have to start over with proper service—potentially missing your hearing date.

Service Methods Ranked by Reliability

Substituted Service

  • Left with competent adult at home or work
  • Also mailed to same address
  • Used when defendant evades personal service
  • Must attempt personal service first

Certified Mail (with restrictions)

  • Clerk mails, return receipt required
  • Only valid if defendant signs
  • If unclaimed/refused: service fails
  • Easy but risky option

Service by Posting

  • Court order required
  • Only after all other methods fail
  • Posted at defendant's last known address
  • Rarely used in small claims

Service Deadlines

Papers must be served minimum days before your hearing:

Service Type Same County Different County Out of State
Personal Service 15 days 20 days 30 days
Substituted Service 25 days 30 days 40 days
Certified Mail 25 days 30 days N/A
Count Carefully: Don't count the day of service or the hearing day. If your hearing is on the 20th and you need 15 days, service must be complete by the 4th at the latest.

How to Serve: Step by Step

Personal Service on an Individual

  1. Locate the Defendant Find their home address, workplace, or another location where they can be found.
  2. Give Papers to Your Server Provide them with copies of your filed claim (Plaintiff's Claim SC-100) plus blank Defendant's Claim form (SC-120).
  3. Server Hands Papers to Defendant Server must identify the person and hand them the documents directly. Defendant doesn't need to accept—setting papers down in front of them counts.
  4. Server Completes Proof of Service Server fills out Form SC-104 with date, time, location, and description of person served.
  5. File Proof of Service Submit the completed SC-104 to the court before your hearing date.

Serving a Business

Business Service Tip: Search the California Secretary of State business database (bizfileonline.sos.ca.gov) to find the registered agent for service. This is the legally designated person/address for receiving lawsuits.

Substituted Service Procedure

Use this when the defendant evades personal service. Requirements:

Attempt Personal Service Make at least 2-3 attempts on different days and times
Document Attempts Record dates, times, and what happened at each attempt
Leave Papers with Responsible Person At home: adult family member. At work: person in charge.
Mail Copy Same Day Server mails another copy by first-class mail to same address
Service Complete 10 Days Later Substituted service isn't complete until 10 days after mailing

The Proof of Service Form (SC-104)

Form SC-104: Proof of Service

This form MUST be filed with the court before your hearing. Without it, you cannot proceed.

Your server must complete:

  • Name and address of person served
  • Date and time of service
  • Address where service occurred
  • Method of service used
  • Description of person served (if substituted)
  • Server's signature under penalty of perjury
File Early: Don't wait until the day of your hearing to file the proof of service. File it as soon as service is complete so the court has it on record.

What If Service Fails?

If you cannot complete service before your hearing date:

Option 1: Request Continuance

Ask the court to postpone the hearing. You can do this:

Option 2: Serve and Re-File

If significant time has passed, you may need to:

Cannot Locate Defendant?

For genuinely hard-to-find defendants, consider:
