A demurrer in California is a pleading challenge that asks the court to throw out a complaint, or part of one, because it fails to state a valid legal claim even if every fact alleged is true. It is filed under Code of Civil Procedure sections 430.10 through 430.80, and it puts the sufficiency of the pleading itself, not the evidence, in front of the judge. A successful demurrer can end a case, or it can force the other side to rewrite its complaint before the litigation moves forward.
Grounds You Can Raise
Section 430.10 sets out eight grounds a defendant can use to demur to a complaint. The most common is that the complaint does not state facts sufficient to constitute a cause of action.1California Legislative Information. California Code CCP 430.10 – Objections to Pleading A negligence complaint that never alleges duty, breach, causation, and damages fails on this ground no matter how much detail surrounds the missing element. A breach-of-contract claim that never identifies the term allegedly broken has the same problem.
The other grounds cover a mix of procedural and substantive defects:1California Legislative Information. California Code CCP 430.10 – Objections to Pleading
- The court lacks jurisdiction over the type of claim.
- The plaintiff lacks legal capacity to sue.
- Another action is already pending between the same parties over the same cause.
- There is a defect or misjoinder of parties.
- The complaint is so uncertain, vague, or contradictory that the defendant cannot reasonably respond.
- In a contract case, the complaint does not say whether the contract is written, oral, or implied.
- A required certificate under Section 411.35 was not filed (applicable in certain professional negligence cases).
A pleading can also be attacked when it requests relief the law does not allow. The classic example is punitive damages tacked onto a pure breach-of-contract claim. California limits exemplary damages to conduct involving fraud, oppression, or malice arising from obligations outside a contract.2California Legislative Information. California Civil Code 3294 – Exemplary Damages Spotting punitive damages in a contract claim with no fraud allegations gives the defendant a strong opening.
General vs. Special Demurrers
Practitioners split demurrers into two working categories. A general demurrer argues the complaint fails to state any cause of action under section 430.10(e). It goes to the core of the claim, and if the court agrees and no amendment can fix the defect, the case is over.
A special demurrer targets technical defects: uncertainty, misjoinder, lack of capacity, or the written-or-oral contract ambiguity.1California Legislative Information. California Code CCP 430.10 – Objections to Pleading Courts nearly always sustain these with leave to amend, because a sloppy pleading may still hide a valid claim. A special demurrer rarely ends a case on its own; it buys time and forces the plaintiff to sharpen the complaint.
Meet and Confer Before You File
The demurring party must contact the opposing side before filing, in person, by phone, or by video conference, to see if the pleading defects can be resolved without the court’s involvement.3California Legislative Information. California Code CCP 430.41 – Objections to Pleadings That discussion has to happen at least five days before the responsive pleading is due.
If the parties cannot meet within that window, the demurring party gets an automatic 30-day extension to file the responsive pleading. Claiming the extension requires a declaration under penalty of perjury describing the good-faith attempt and why it did not succeed. The 30 days run from the original filing deadline, and the party is protected from default during that time.3California Legislative Information. California Code CCP 430.41 – Objections to Pleadings Any further extension needs a court order and good cause.
One quirk worth knowing: a failed or inadequate meet-and-confer session is not itself grounds to sustain or overrule the demurrer. The statute says so directly. The court still rules on the merits. But if the judge decides the discussions were not in good faith, the hearing can be continued to give the parties another shot, which delays everything.
Deadlines, Hearing Dates, and Fees
A defendant has 30 days from service of the complaint to respond, and a demurrer counts as that response.4California Legislative Information. California Code CCP 412.20 – Summons Miss the deadline and the plaintiff can seek a default judgment, ending the case without the defendant ever being heard.
Once filed, the demurrer hearing must be set no more than 35 days after filing, or on the first available date after that.5Judicial Branch of California. California Rules of Court Rule 3.1320 – Demurrers Under CCP 1005(b), the demurring party gives at least 16 court days of notice. Opposition papers are due at least nine court days before the hearing, and any reply at least five court days before.
Filing fees depend on whether the demurrer is the defendant’s first appearance. If it is, the fee matches the first-appearance fee: $435 in unlimited civil cases (claims over $35,000), $370 in limited civil cases between $10,000 and $35,000, and $225 in limited civil cases up to $10,000. If the defendant has already appeared, the motion fee is $60.6Judicial Branch of California. Statewide Civil Fee Schedule Effective January 1, 2026
What the Court Looks At
The court accepts every fact in the complaint as true and asks whether those facts add up to a valid cause of action. No weighing of evidence, no witnesses, nothing outside the four corners of the complaint. The one exception is judicial notice, which lets the judge consider other court records, official government acts, published statutes, and facts not reasonably subject to dispute.7California Legislative Information. California Evidence Code 452 – Judicial Notice A party asking for judicial notice must give the other side enough advance notice to prepare and give the court enough information to verify the material.8California Legislative Information. California Evidence Code 453 – Compulsory Judicial Notice
Many California courts issue tentative rulings the day before the hearing. Where a court follows this practice, it posts the tentative by 3:00 p.m. the court day before. If the court has not ordered oral argument and no party notifies the court and opposing parties of an intent to appear by 4:00 p.m. that day, the tentative becomes the final ruling. The notice must be by telephone or in person. Cases get decided this way when a losing party fails to call in on time. Not every court uses this system. Some post a tentative but hold the hearing anyway without requiring notice of intent to appear.9Judicial Branch of California.

How the Court Can Rule
Sustained With Leave to Amend
The court agrees the pleading is deficient but lets the plaintiff try again. This is the usual outcome on a first demurrer, because California courts prefer to resolve disputes on the merits. The plaintiff has 10 days to file an amended complaint unless the court sets a different deadline.5Judicial Branch of California. California Rules of Court Rule 3.1320 – Demurrers
Sustained Without Leave to Amend
The court finds no amendment could fix the defect. Either party can then move for dismissal under CCP 581(f), and that dismissal is with prejudice.10California Legislative Information. California Code CCP 581 – Dismissal Under Blank v. Kirwan, denying leave to amend is an abuse of discretion if there is a reasonable possibility the defect can be cured.11Justia. Blank v. Kirwan
Overruled
The court finds the complaint does state a valid claim. The defendant has 10 days to file an answer, and the case moves into discovery.5Judicial Branch of California. California Rules of Court Rule 3.1320 – Demurrers An overruled demurrer is not the last word for the defendant. The same legal arguments can often be raised later on summary judgment once evidence is in the record.
Amending After a Sustained Demurrer
An amended complaint has to actually cure the defect the court identified. Reasserting the same allegations invites another demurrer and a real chance of dismissal with prejudice.
California caps the amendments a plaintiff can make in response to demurrers at three before the case is at issue. After that, the plaintiff must show the court what additional facts would be pleaded and demonstrate a reasonable possibility of curing the defect.3California Legislative Information. California Code CCP 430.41 – Objections to Pleadings The cap does not count amendments made as a matter of right before any demurrer is filed.
On that right: under CCP 472, a plaintiff can amend once without the court’s permission. That right exists before an answer or demurrer is filed, and also after a demurrer is filed but before it is heard, as long as the amended complaint is served before the opposition deadline. A plaintiff who sees a demurrer coming and knows the complaint has a fixable weakness can amend before the hearing, mooting the demurrer entirely.
If leave to amend is granted and the plaintiff misses the deadline to file the amended complaint, either party can move for dismissal.10California Legislative Information. California Code CCP 581 – Dismissal Courts treat missed amendment deadlines as abandonment.
Motions to Strike
A motion to strike under CCP 435 is the surgical companion to the demurrer. Where a demurrer attacks a whole cause of action, a motion to strike targets specific portions of a pleading: a prayer for relief, an irrelevant allegation, or language that exists only to prejudice.12California Legislative Information. California Code CCP 435 – Motion to Strike Take the punitive-damages problem above. If a complaint pleads both a viable negligence claim and a contract claim that improperly seeks punitive damages, a demurrer is a blunt tool because the negligence claim is fine. A motion to strike removes the punitive damages request while leaving the rest of the pleading in place.
When a motion to strike is filed alongside a demurrer, the court hears them together. Filing the motion to strike does not extend the demurrer deadline, so the two have to be prepared in parallel.
Demurring to an Answer
Plaintiffs can demur too. Under section 430.20, a plaintiff can challenge a defendant’s answer on three grounds: it fails to state facts sufficient to constitute a defense, it is uncertain, or in a contract case it does not clarify whether the contract is written or oral.13California Legislative Information. California Code CCP 430.20 – Grounds for Demurrer to Answer It is less common than a demurrer to a complaint, but it can be useful when an affirmative defense is invalid on its face or so unclear the plaintiff cannot prepare a response.
Appealing After Dismissal
A demurrer ruling by itself is not appealable. A plaintiff whose case is dismissed after a demurrer sustained without leave to amend has to wait for entry of a formal judgment of dismissal before filing an appeal.14California Courts of Appeal. Summary Judgment and Demurrer – Appendix 5 On review, the appellate court uses the same standard the trial court should have used: accept the facts as pleaded and ask whether they state a cause of action. If there is a reasonable possibility the defect can be cured, the court will reverse and send the case back.11Justia. Blank v. Kirwan A plaintiff can raise the argument that leave to amend should have been granted for the first time on appeal, which is unusual in appellate practice.
