Unlawful Detainer Service in California

An eviction in California is two service events: the 3-day, 30-day or 60-day notice, served under Code of Civil Procedure section 1162 before you can file, and the summons and complaint after filing. Get either wrong and the case can be dismissed with the tenant still in possession.

StrikeServe serves both stages through California registered process servers, logs each attempt with GPS and a timestamp, and returns a signed proof: a declaration for the notice, or the POS-010 for the summons.

What gets served

Which documents get served depends on the stage.

Notice

3-day, 30-day or 60-day notice

Three-day notices are in Code of Civil Procedure section 1161; 30- and 60-day notices in Civil Code section 1946.1. All are served under section 1162.

UD-100

Complaint—Unlawful Detainer

Starts the court case after the notice period runs; attaches the notice and its proof of service.

SUM-130

Summons—Unlawful Detainer—Eviction

Tells the tenant they have 10 days, excluding weekends and judicial holidays, to respond. Served with the complaint on every named tenant.

POS-010

Proof of Service of Summons

Completed by the server after delivering the summons and complaint; filed with the court.

Include the blank UD-105 Answer and any prejudgment claim form your court requires.

Who can serve it

Section 1162 does not require a third party to serve the notice, so a landlord or agent may, though many use a disinterested server. The summons is different: Code of Civil Procedure section 414.10 limits service of a summons to a person at least 18 who is not a party, and the landlord is the plaintiff, so the landlord cannot serve the SUM-130.

Because the proof is scrutinized at any default or trial, most landlords use a registered server for the summons stage; the registration number goes on the POS-010.

Stage one: serving the notice under section 1162

Section 1162 lists the methods in order. Personal delivery comes first. If the tenant is absent from home and work, the server may leave a copy with a person of suitable age and discretion at either place and mail a copy to the residence. If neither place can be found or no suitable person is there, the server may post the notice in a conspicuous place on the property, give a copy to anyone living there, and mail a copy to the tenant at the property. The proof records which method was used and why, and is attached to the UD-100.

Stage two: serving the summons and complaint

After the notice period expires and the complaint is filed, the SUM-130 and UD-100 are served like any civil summons: personal service under section 415.10 first, then substituted service under section 415.20(b) after reasonable diligence, complete ten days after mailing. Under section 1167, as amended effective 2025, the response is due within 10 days after service, excluding weekends and judicial holidays.

Posting and mailing requires a court order

Posting the summons on the door is not an option unless a judge has ordered it. Under Code of Civil Procedure section 415.45, an unlawful detainer summons may be served by posting only after an affidavit satisfies the court that the tenant cannot with reasonable diligence be served any other way. The court then orders the summons posted on the premises and a copy mailed by certified mail to the tenant's last known address, and service is complete on the tenth day after posting and mailing. StrikeServe's Declaration of Non-Service is the kind of evidence that supports that application.

How proof of service errors end cases

A proof that names the wrong tenant, omits the mailing date for substituted service, describes a method section 1162 does not allow, or is signed by the plaintiff can lead to a denied default, a granted motion to quash or a dismissal, and weeks lost serving again.

How StrikeServe records attempts

Every visit is recorded on your timeline with GPS coordinates, a timestamp and notes: who answered, whether the tenant was seen, vehicles present, whether a suitable adult was available. Those notes become the declaration of diligence for substituted service or posting, or the Declaration of Non-Service if service fails.

Unlawful detainer: frequently asked questions

Can a landlord serve the 3-day notice personally?
Section 1162 does not prohibit it, but the person who served may have to testify, so many landlords use a disinterested registered server.
Can a landlord serve the unlawful detainer summons and complaint?
No. Section 414.10 requires a server who is at least 18 and not a party, and the landlord is the plaintiff.
Can the summons be posted on the door if the tenant will not answer?
Only with a court order under section 415.45, after an affidavit shows reasonable diligence. Service is complete ten days after posting and mailing.
How long does the tenant have to respond after being served?
Under section 1167, 10 days after service, excluding Saturdays, Sundays and judicial holidays.
What if there are several adults in the unit?
Each named tenant is a separate serve with its own proof; place one order per tenant.
What does StrikeServe deliver when the serve is complete?
A POS-010 for the summons or a declaration for the notice, signed by the registered server under penalty of perjury, or a Declaration of Non-Service if the tenant cannot be served.
