Served in California: What the First 30 Days Actually Look Like

A California civil defendant who has just been served typically hears one thing: you have 30 days to respond. That’s correct. But the 30-day window is not a deadline for filing an answer. It is a deadline for choosing among several response options — each of which sends the case in a different direction.

This article walks through what actually happens in those 30 days, in the order it happens, and what the decisions look like along the way.

Day 0: confirm the service

Service is the first thing to verify. California Code of Civil Procedure §§ 415.10 et seq. specify the methods by which a defendant can be served — personal service, substitute service, service by mail with acknowledgement, service by publication.

Each method has its own procedural requirements. If service wasn’t valid, the 30-day clock hasn’t started, and a motion to quash service under CCP § 418.10 may be available. Improper service is a defense that disappears if the defendant appears generally before raising it.

Confirm:

• Who served the defendant
• When (date and time, exactly)
• What method
• Whether the proof of service has been filed
• Whether the documents served match what was filed

For corporate defendants, service must be on a designated agent or through specific corporate-officer service procedures (CCP § 416.10). For LLC defendants, similar rules apply via the designated agent.

Days 1–7: read the complaint

The complaint is the core document. Read it twice. Read every exhibit attached. Read it again with a copy of the relevant contract or governing instrument open alongside.

While reading, look for:

• The causes of action pleaded — does each state a viable claim under California law on the facts alleged?
• The damages claimed — are they specifically pleaded and legally available?
• The relief sought — is it limited to what the law actually authorizes?
• Allegations that may be subject to a motion to strike under CCP § 435 (improper, irrelevant, or unsupportable matter)
• Allegations that may be subject to demurrer under CCP § 430.10 (insufficient as a matter of law)

This first read informs every subsequent decision.

Days 7–14: choose the response

A California defendant has three primary response options under CCP § 412.20:

Demurrer

A demurrer asserts that even if everything in the complaint were true, it doesn’t state a claim under California law (CCP § 430.10). A successful demurrer typically comes with leave to amend, which means the plaintiff gets another chance — but the plaintiff also has to figure out how to fix the problem.

Demurrer is most useful when:

• A specific cause of action is missing a required element
• A claim is barred by limitations on its face
• The pleading is uncertain in a way that makes the defense impossible
• A claim against a specific defendant is unsupported by any alleged facts

Demurrer extends the response timeline (the demurrer is filed in place of the answer; if overruled or sustained without leave, the answer comes after).

Motion to strike

A motion to strike under CCP § 435 targets specific allegations or prayers for relief — improper damages claims, irrelevant allegations, requests for relief that aren’t available on the facts pleaded. It doesn’t challenge the complaint as a whole.

Motion to strike is most useful when:

• The complaint asks for damages that aren’t recoverable
• Specific allegations are scandalous, irrelevant, or improper
• A request for punitive damages is unsupported

Answer

An answer admits or denies each allegation, asserts affirmative defenses, and (where applicable) raises counterclaims. It is the most common path forward and the most committal — once the answer is filed, the case is at issue and discovery opens.

Answer is most useful when:

• The complaint isn’t legally insufficient
• The factual disputes are real and need to be developed
• The defense has affirmative defenses or counterclaims to assert

Choosing among these is not always obvious. A demurrer that delays the case may benefit a defendant facing time pressure on its own preparation. An answer that gets the case moving may benefit a defendant facing time pressure from a deteriorating witness pool or evidence record.

Action step

Within the first week of service, calendar the response deadline (the actual calendar date, not "30 days from now") and put a hard reminder at 10 days before that date. Defaults under CCP §§ 580–585 are recoverable but expensive to unwind, and the cost of unwinding always exceeds the cost of responding on time.

Days 14–25: prepare the chosen response

If demurrer or motion to strike: identify the legal grounds with specific case authority, draft the moving papers, and meet-and-confer under CCP § 430.41 (for demurrers) before filing. The meet-and-confer requirement is procedural; failing to satisfy it can result in continuance.

If answer: draft the responses to each allegation, identify the affirmative defenses, identify any counterclaims, and prepare verification if the complaint is verified.

In all cases, the discovery preservation work continues in parallel. Documents shouldn’t be deleted, communications shouldn’t be lost, witnesses shouldn’t be told to say anything they wouldn’t say under oath.

Days 25–30: file

The response is filed and served on the plaintiff (and any other parties). California requires service to be effected through specific methods (CCP §§ 1010 et seq.), and the proof of service must be filed. A response filed but not served is incomplete.

For demurrers and motions to strike, the hearing date is set when the motion is filed. Briefing schedules follow. The plaintiff has 9 court days to oppose; the defendant has 5 court days to reply.

For answers, the case is at issue once the answer is filed. Discovery opens immediately. The case management conference follows on the schedule the court sets.

Common pitfalls

Three patterns produce avoidable problems in the first 30 days:

• Default by miscalendar.A defendant who counts “30 days” from the wrong starting date — service date vs. receipt date vs. agent-receipt date — can default.
• General appearance before raising service defects.If service was defective, the defendant must raise the defect by motion before any other appearance. Filing an answer or any general motion waives the defect.
• Filing without meet-and-confer.Demurrers in California require pre-filing meet-and-confer under CCP § 430.41. Missing this step can result in continuance and procedural embarrassment.

When to involve counsel

For any contested California civil defense, counsel involvement within the first week of service is the practical baseline. The 30-day window is too short for a defendant to evaluate options, prepare materials, and execute a response without experienced help — and the consequences of missteps in those weeks can shape the entire case.

For matters where the complaint is procedurally weak or where the merits are heavily one-sided in the defendant’s favor, counsel can assess whether demurrer, motion for judgment on the pleadings, or even early summary judgment may shorten the case significantly.
