Demurrers and Oppositions in California State Court: A Practical Guide

If you're involved in a lawsuit in California, there's a good chance you'll hear the word "demurrer." It sounds technical and honestly, a little intimidating but the idea behind it is actually pretty simple.

A demurrer is basically one side saying: "Even if everything you're claiming is true, you still don't have a valid legal case." That's it. But where things get tricky is how you respond to it and what happens next. Let's walk through it in a way that actually makes sense.

So… What's Really Going On Here?

When someone files a lawsuit, they start with a document called a Complaint. That's where they explain what happened and why they think they're entitled to relief. A demurrer doesn't argue about whether those facts are true or false. Instead, it asks a different question: Do these facts, assuming they're true, actually add up to a legal claim? If the answer is "no," the court may stop the case right there or at least force the plaintiff to fix it.

What Courts Actually Do on a Demurrer

California courts are very clear about the standard: (1) A demurrer tests legal sufficiency and not truth of facts; (2) The court must accept all properly pleaded facts as true.

As held in Serrano v. Priest and Blank v. Kirwan, courts must: "treat the demurrer as admitting all material facts properly pleaded" Similarly, courts emphasize that: A demurrer cannot resolve factual disputes (Cundiff v. GTE California, Inc.) This principle is critical and often misunderstood.

Why Do Defendants File Demurrers?

From a practical standpoint, a demurrer is often about testing the strength of the complaint early. Some common reasons include: (i) the complaint is too vague; (ii) key details are missing; (iii) the legal claim doesn't quite fit the facts; and (iv) the case was filed too late. Sometimes it's strategic, and sometimes it's legitimate. Often, it's a bit of both.

Timing Matters More Than You Think

In California state court, a defendant usually has about 30 days to respond to a complaint and that response can be a demurrer.

But before filing, both sides are supposed to meet and confer. This just means having a real conversation (usually between attorneys) about what's wrong with the complaint and whether it can be fixed without involving the judge. And yes sometimes that actually works.

If You're the Plaintiff: The Opposition Is Your Moment

If someone files a demurrer against your complaint, don't panic. This is very common. Your response is called an opposition, and this is your chance to explain: (1) why your case does make legal sense; (2) why your facts are enough; and (3) why the court should let your case move forward.

What a Good Opposition Actually Does

A strong opposition isn't just defensive but it's clear and focused. It usually: (a) walks the judge through the story in a logical way; (b) connects your facts to actual legal requirements; (c) pushes back on the other side's arguments directly. And just as important, it doesn't ignore weak spots. It addresses them.

What Happens After That?

Once the demurrer and opposition are filed, things move pretty quickly: (1) a hearing is scheduled; and (2) the judge makes a decision. And that decision can go a few different ways.

The Three Most Likely Outcomes

1. The Demurrer Is Overruled

This is the best-case scenario for the plaintiff. The judge is basically saying: "Your complaint is good enough. Let's move forward."

2. The Demurrer Is Sustained With Leave to Amend

This is very common. It means: "There are problems but you get a chance to fix them." You'll usually have a short window to file an updated, stronger complaint.

3. The Demurrer Is Sustained Without Leave to Amend

This is more serious. It means the court doesn't think the problem can be fixed and that claim (or sometimes the whole case) may be dismissed.

Real Causes of Action (From Actual Litigation)

Here are the most common claims being challenged and defended at the demurrer stage:

1. Breach of Contract

To survive demurrer, a plaintiff must allege: (1) Existence of contract; (2) Performance; (3) Breach; (4) Damages. Courts reaffirm these elements in cases like: Reichert v. General Ins. Co. and Oasis West Realty, LLC v. Goldman.

In one of our law firm cases, the complaint survived because it alleged: (1) A written agreement; (2) Full performance (e.g., content creation); (3) Non-payment of revenue share; and (4) Specific damages

2. Fraud / Fraudulent Misrepresentation

Fraud requires: (1) Misrepresentation; (2) Knowledge of falsity; (3) Intent to induce reliance; (4) Justifiable reliance; and (5) Damages. As stated in Lazar v. Superior Court: Fraud must be pled with specificity but not proven at this stage. A claim typically accrues when all elements of the cause of action are complete.

In the Superior Court of California, Los Angeles matter handled by our firm, the court overruled the demurrer in its entirety, allowing all causes of action to proceed past the pleading stage.

3. Statute of Limitations in California Demurrers

One of the most common arguments raised in a demurrer is that the plaintiff's claims are time-barred. While this can be a powerful defense, it is also frequently misapplied at the pleading stage. Under California law, a cause of action must be filed within a specified time period after it "accrues." In California, the statute of limitations depends on the type of claim: Written contracts: 4 years (Cal. Code Civ. Proc. § 337); Oral contracts: 2 years (Cal. Code Civ. Proc. § 339). These time periods determine when a claim must be filed but they do not automatically resolve a case at the demurrer stage.

Even where a 4-year (written contract) or 2-year (oral contract) period applies, California law recognizes the continuous accrual doctrine: (1) when obligations are ongoing (like payments or royalties); and (2) each breach starts a new limitations period.

In one of our firms'cases, the court rejected defendants' statute of limitations arguments at the pleading stage, where the complaint alleged continuous accrual of damages and ongoing failures to perform under a written agreement, ultimately overruling the demurrer in its entirety.

Final Thoughts

If you're dealing with a demurrer in California state court, you're not in some rare or unusual situation. This is a normal part of litigation. The key is understanding what's really being argued: Not whether something happened but whether it's been properly pled. And that's something that can often be fixed with the right approach.

If you're facing a demurrer or thinking about filing one, getting clear, strategic guidance early on can make the process far less overwhelming and a lot more effective.
