How to Serve Your Landlord Before Small Claims Court — And What Happens If You Get It Wrong

The Short Answer

After you file a Plaintiff's Claim (Form SC-100), your landlord has to be formally served with a copy before the trial. Someone who is at least 18 and not listed in the case must do it, so you cannot serve the papers yourself (Form SC-104B; Code of Civil Procedure § 116.340). The two methods you arrange yourself are personal service and substituted service (Code of Civil Procedure §§ 415.10, 415.20, cited on Form SC-104).

Timing is strict. Personal service must be done at least 15 days before the trial, or 20 days if the landlord is outside the county. For substituted service, the extra copy must be mailed at least 25 days before the trial, or 30 days if the landlord is outside the county. The original Proof of Service (Form SC-104) must be filed at least 5 days before the trial (Form SC-104B). The Judicial Council's form is blunt: the judge cannot hear your case unless the court papers were served correctly.

The Example: Ana Serves Her Landlord's LLC

Ana rented an apartment in San Jose. Her landlord kept her $2,200 deposit, so she filed an SC-100. Her lease named "Oakview Properties LLC" as the owner, and a property manager handled day-to-day issues.

Ana's trial date was 40 days away. Before hiring anyone, she needed to know exactly whom to serve, how, and by when. We follow her through the rest of this guide.

The Ways the Claim Can Be Served

You cannot mail the claim to your landlord yourself. Certified mail is a method only the court clerk can use, and if anyone other than the defendant signs the receipt, you have to serve again (Form SC-104B). That is why many tenants go straight to personal or substituted service by a registered process server.

How to Serve Your Landlord, Step by Step

Step 1: Identify exactly whom to serve

You must serve the right person and write the exact name of the business and the person served on your proof of service (Form SC-104C). Form SC-104C lists who to serve for each kind of defendant:

• An individual landlord: serve that person.
• A landlord, generally: the property owner or manager (Form SC-104C, referring to Civil Code §§ 1962–1962.7).
• An LLC, LP, or LLP: the agent for service listed with the California Secretary of State.
• A corporation: the agent for service listed with the Secretary of State, or a corporate officer such as the president, secretary, treasurer, CEO, CFO, or general manager.

Ana searched the Secretary of State's business search (bizfileonline.sos.ca.gov) for Oakview Properties LLC and found its agent for service.

Step 2: Choose your server

The server can be a friend, a process server you pay, or the sheriff or marshal. The server must be at least 18 and not listed in the case (Form SC-104B). Give the server a separate Proof of Service form for each person, business, or public entity you are suing.

Step 3: Count your deadline backward from the trial date

Look at the trial date on page 1 of your SC-100 (Form SC-104B):

• Personal service: at least 15 days before the trial, or 20 days if the person or business is outside the county.
• Substituted service: the server must mail the extra copy at least 25 days before the trial, or 30 days if outside the county. Substituted service is not complete until 10 days after the copy is mailed (Form SC-100-INFO).

You can always serve earlier than the deadline. Ana had 40 days, so she had room for a second attempt if the first one failed.

Step 4: Personal service: hand the papers to the right person

The server walks up to the person to be served, says "These are court papers," and gives them copies of all the papers checked on Form SC-104. If the person will not take them, the server can leave them near the person (Form SC-104B). Then the server fills out and signs page 2 of Form SC-104.

Step 5: Substituted service: leave the papers with an adult, then mail a copy

If the person cannot be found, the server can give the papers to (Form SC-104B):

• a competent adult at the home of, and living with, the person being served;
• an adult who seems to be in charge where the person usually works; or
• an adult who seems to be in charge where the person receives mail, such as a private mailbox (not a U.S. Postal Service P.O. Box), but only if the person's physical address is not known.

The server writes down that adult's name (or describes them), says "Please give these court papers to [name]," and leaves the copies. Then the server mails another copy by first-class mail to the person at the same address and signs page 2 of Form SC-104.

Step 6: File the Proof of Service

The original completed Proof of Service (Form SC-104) must be filed at least 5 days before your trial. A process server or sheriff can file it with the clerk. If a friend served the papers, they give the form back to you to file. Keep a copy and bring it to court (Form SC-104B).

Step 7: If you cannot serve in time, act before the trial

If you could not serve your claim before the deadline, talk to your small claims clerk; each county has its own rules. If you served some defendants but not all, you may need to file a Request to Postpone Trial (Form SC-150) at least 10 days before the trial date, or explain why you could not, and give or mail a copy to the other parties. The court may postpone your trial for 15 days or more (Form SC-104B).

Key Service Rules

Frequently Asked Questions

Can I serve my landlord myself?

No. The person who serves the papers must be at least 18 and not listed in the case (Form SC-104B; Code of Civil Procedure § 116.340). A friend, a registered process server, or the sheriff or marshal can serve for you.

Can I just mail the claim to my landlord?

No. You cannot serve the claim by mailing it yourself. The court clerk can mail it by certified mail for a fee, but if your landlord or their agent does not sign the receipt with their complete name, or someone else signs it, you have to serve again by personal or substituted service (Form SC-104B). A mailed demand letter before you file is a different thing and is not service of the claim.

Who do I serve if my landlord is an LLC or a corporation?

For an LLC, serve the agent for service listed with the California Secretary of State. For a corporation, serve that agent or a corporate officer such as the president or general manager. Write the exact business name and the person served on your proof of service (Form SC-104C).

What if my landlord avoids being served?

Substituted service lets the server leave the papers with an adult at the person's home or workplace and then mail another copy (Form SC-104B; Code of Civil Procedure § 415.20). Allow extra time: the copy must be mailed at least 25 days before the trial, or 30 days if the landlord is outside the county.

What happens if service is late or wrong?

The judge cannot hear your case unless the papers were served correctly (Form SC-104B), so the trial may be postponed. A judgment entered without proper service is also easier to undo: a defendant who was not properly served has 180 days to ask the court to cancel the judgment (Form SC-130). See what happens when a landlord doesn't show up.

Do I have to serve the landlord again if they file a claim against me?

The deadlines are different for a Defendant's Claim (Form SC-120): it must be served at least 5 days before the trial, or at least 1 day before if the defendant was served 10 days or less before the trial (Form SC-104B). See what to do if your landlord sues you.
