Introduction
California defendants don't have to answer a defective complaint and wait for discovery. Two pleading-stage tools can narrow or end a case early: the demurrer and the motion to strike. They sound similar. They do different jobs.
Pick the wrong one and you risk a denied motion, wasted fees, and an amended complaint that fixes the problem. This article covers how each motion works, what each can target, the key procedural requirements, and how to choose between them.
This article is for general information only and is not legal advice. Verify all authority and deadlines with qualified California counsel.
Key Takeaways
- A demurrer tests whether the facts alleged, assumed true, state a legally sufficient claim.
- A motion to strike removes specific improper matter or unsupported relief from a pleading.
- Evaluate the defect, remedy, amendment risk, cost, and meet-and-confer duties before filing either.
- Verify deadlines and local rules against current statutes before relying on this guide.
What Is a Demurrer in California?
Definition and legal test
A demurrer challenges the legal sufficiency of a complaint, cross-complaint, or an individual cause of action. It can also target an answer. Under CCP 430.50, it may attack the whole pleading or specific causes of action.
The court treats the demurrer as admitting material facts properly pleaded, but not contentions, deductions, or conclusions of fact or law. As Blank v. Kirwan (1985) 39 Cal.3d 311 puts it, the pleading is read as a whole and in context.
The court looks at the face of the pleading and matters subject to judicial notice under CCP 430.30. It does not weigh evidence or judge credibility.
Common grounds for a demurrer
CCP 430.10 lists the current grounds:
- No jurisdiction over the subject of the cause of action
- Plaintiff lacks legal capacity to sue
- Another action is pending between the same parties on the same cause of action
- Defect or misjoinder of parties
- Failure to state facts sufficient to constitute a cause of action
- Uncertainty (ambiguous or unintelligible pleading)
- In a contract action, it cannot be ascertained whether the contract is written, oral, or implied by conduct
- No certificate filed as required by CCP 411.35
Common examples include:
- A negligence claim that never alleges damages (missing an element)
- A complaint so garbled you can't tell which defendant did what (uncertainty)
- A breach-of-contract count that never states whether the contract was written, oral, or implied (CCP 430.10(g))
CCP 430.60 requires you to distinctly specify each ground. A vague demurrer can be disregarded.
General and special demurrers
Failure to state a cause of action is the general-demurrer ground. Uncertainty under 430.10(f) is a special-demurrer ground.
CCP 92(c) bars special demurrers in limited civil cases. Under CCP 430.80(a), subject-matter jurisdiction and failure to state sufficient facts survive even if you don't raise them by demurrer.
Demurrer to evidence is a different thing
A "demurrer to evidence" is a trial-stage concept, not a CCP 430.10 motion. Lussier v. San Lorenzo Valley Water Dist. (1988) 206 Cal.App.3d 92 calls nonsuit "tantamount to a demurrer to the evidence." The modern trial procedures are:
- Nonsuit (CCP 581c): jury trials, after plaintiff's opening statement or evidence
- Directed verdict (CCP 630): jury trials, after all parties complete their evidence
- Motion for judgment (CCP 631.8): court trials, after a party completes its evidence
What Is a Motion to Strike in California?
Definition and legal purpose
CCP 435 through 437 govern motions to strike. Section 436 lets the court strike any irrelevant, false, or improper matter inserted in a pleading. It also lets the court strike all or part of a pleading not drawn or filed in conformity with California law, a court rule, or a court order.
The motion usually targets specific allegations or requests for relief. The rest of the pleading stays intact. As with a demurrer, the court looks at the face of the pleading and judicially noticeable matters under CCP 437.
When a motion to strike is useful
- Defective theory inside a viable claim. A demurrer cannot attack part of a cause of action (PH II, Inc. v. Superior Court (1995) 33 Cal.App.4th 1680). A strike can reach a facially defective portion, but courts want it used "cautious[ly] and sparing[ly]," not as a "line item veto."
- Unsupported prayers for relief. CCP 431.10(b) treats unsupported demands as immaterial, so you can challenge punitive damages, treble damages, or fee requests the pleaded facts or law don't support.
- Improper matter. Irrelevant, false, or scandalous allegations can go. Disputes about whether allegations are true belong in discovery and trial, not here.
Punitive damages are the classic example. Civil Code 3294 requires oppression, fraud, or malice, and corporate employers face added requirements under 3294(b).
Grieves v. Superior Court (1984) 157 Cal.App.3d 159 holds that punitive damages are incident to a cause of action, and that an intentional-tort label alone isn't enough. There the court overruled the battery demurrers but struck the punitive allegations with leave to amend.
Clauson v. Superior Court (1998) 67 Cal.App.4th 1253 shows the limit: allegations read as a whole and assumed true can be enough, and the strike motion was denied.
Limits and possible results
A strike motion is not a substitute for a demurrer when an entire cause of action fails. Ferraro v. Camarlinghi (2008) 161 Cal.App.4th 509 rejected using a strike motion for a failure-to-state-a-cause challenge. It also isn't a vehicle for resolving factual disputes.
Possible outcomes:
- Granted in whole or in part, removing the challenged matter from the pleading
- Denied, leaving the allegations or prayer intact
- Granted with leave to amend (CCP 472a lets the court order amendment on proper terms)
- Granted without leave where no cure is possible
Demurrer vs. Motion to Strike: Which Tool Should You Use?
Compare by question, target, and remedy
| Factor | Demurrer | Motion to Strike |
|---|---|---|
| Question | Do the alleged facts state a recognized claim? | Should this matter or relief stay in the case? |
| Target | Whole cause of action or defense | Specific allegations, theories, or prayers |
| Facts | Well-pleaded facts assumed true | Allegations read in context, assumed true |
| Record | Face of pleading, judicial notice | Face of pleading, judicial notice |
| Result | Can dispose of a claim | Narrows a claim |
Apply the distinction
Failure of elements. A plaintiff pleads fraud without alleging a misrepresentation or reliance. The whole count fails, so demurrer is the right tool.
Viable claim, overreaching remedy. A negligence claim is sound, but the complaint adds a conclusory punitive-damages demand with no facts showing malice. Move to strike the punitive allegations.
Both defects. If the complaint has one deficient count and also improper matter in a sound count, file both. They must be noticed for and heard at the same time (CRC 3.1322(b)). Be selective, though. Marginal challenges raise cost and invite a stronger amended complaint.
Cost-benefit and amendment analysis
A win that only produces an amended pleading may not help much. Ask whether removing the matter will materially reduce:
- Discovery scope (Civil Code 3295(c) restricts pretrial financial-condition discovery absent a court order)
- Damages exposure
- Confidentiality risk
- Settlement pressure
- Trial complexity
Courts grant leave to amend when there is a reasonable possibility of cure, and the plaintiff bears the burden of showing it (Goodman v. Kennedy, 18 Cal.3d 335). Weigh the likely amended pleading against what the motion costs.
A quick checklist:
- Identify the defect.
- Pinpoint the exact pleading language.
- Select the narrowest effective remedy.
- Confirm authority and timing.
- Complete meet and confer.
- Assess the likely result if leave to amend is granted.
Filing, Meet-and-Confer, and Hearing Procedure
Before filing
CCP 430.41 (demurrers) and 435.5 (motions to strike) require meet and confer:
- Confer in person, by telephone, or by video conference
- Identify the challenged causes or allegations and the legal grounds
- Confer at least 5 days before the responsive pleading or motion deadline
- File a declaration describing the conferral, or the other side's failure to respond or confer in good faith
If you can't confer in time, file a declaration under penalty of perjury by the deadline. That gives an automatic 30-day extension.
Inadequate conferral alone isn't grounds to sustain, overrule, grant, or deny. Exceptions cover unrepresented incarcerated parties and unlawful-detainer-type actions; self-representation alone is not an exception.
Keep a written record of issues raised, proposed amendments, and responses.
Deadlines and motion papers
| Item | Timing |
|---|---|
| Demurrer to complaint | 30 days after service (CCP 430.40(a)) |
| Demurrer to answer | 10 days after service |
| Moving papers | 16 court days before hearing (CCP 1005(b)) |
| Opposition / reply | 9 / 5 court days before hearing |
| Demurrer hearing | Within 35 days of filing, or first available date (CRC 3.1320(d)) |
Service method adds time: 5 calendar days for in-state mail, 10 for interstate, 20 for international, and 2 court days for electronic service under CCP 1010.6. Filing a strike notice extends time to answer but not time to demur (CCP 435(d)).
A typical package includes:
- Notice of motion
- Memorandum of points and authorities
- Meet-and-confer declaration
- Proposed order
- Proof of service
Memoranda are capped at 15 pages for opening and opposition papers and 10 for replies (CRC 3.1113). Under CRC 3.1322(a), quote challenged portions in full, unless striking an entire paragraph, cause of action, count, or defense.
Hearing and post-ruling steps
Hearings involve argument on legal sufficiency, not witness testimony. Many courts issue tentative rulings, and CRC 3.1308 governs how to request argument, generally by 4 p.m. the preceding court day.
After a ruling:
- Sustained with leave: the court fixes the amendment time (CCP 472a). Otherwise, CRC 3.1320(g) gives 10 days.
- Overruled: you generally answer within the time set by CRC 3.1320(j).
- Sustained without leave: the claim is out, but the order isn't itself appealable; review comes after judgment (Zipperer v. County of Santa Clara).
Confirm every deadline from the court's order and notice of ruling (CCP 472b).
Strategic Checklist for California Defense Teams
Review the pleading claim by claim
- Map each cause of action to its elements, the facts alleged for each, and each request for relief
- Flag allegations that invite needless discovery or privacy exposure
- Separate legal-sufficiency issues from factual defenses, which belong in the answer, discovery, summary judgment, or trial
Evaluate the business and litigation value
A technically successful motion can still have little strategic value if the plaintiff simply re-pleads. Ask whether an early challenge cuts:
- Claim scope
- Damages exposure
- Discovery burden or cost
Never reuse a template or prior motion without checking current authority, local rules, deadlines, and claim-specific pleading requirements.
Organize the defense workflow
Pleading review is document-heavy. A secure, defense-focused platform such as OraClaim pulls statements, records, and timelines into a unified, searchable view. That helps teams organize pleadings and surface allegations and requests for relief for attorney review.
Its closed, access-restricted design is intended to support privilege and work-product protection. Users remain responsible for their own access and collaboration decisions.
Technology supports review. It does not replace attorney analysis, meet-and-confer obligations, or court-specific compliance. Qualified counsel decides whether to file.
Frequently Asked Questions
What does "motion to strike" mean?
A motion to strike is a California pleading challenge that removes specific irrelevant, false, improper, or legally unsupported matter from all or part of a pleading, including certain unsupported requests for relief.
What are the grounds for filing a demurrer to evidence?
A demurrer to evidence challenges the sufficiency of the opposing party's evidence at trial, not at the pleading stage. In California it corresponds to nonsuit (CCP 581c) in jury trials, with directed verdict and CCP 631.8 judgment as related procedures.
What is the difference between a demurrer and a motion to strike in California?
A demurrer challenges whether a cause of action is legally sufficient. A motion to strike generally targets specific improper allegations or requests for relief.
How long do you have to file a demurrer or motion to strike in California?
A demurrer to a complaint is generally due within 30 days of service. Timing varies with service method, extensions, and local rules, so check the current statutes, Rules of Court, and court orders.
What happens if a demurrer is sustained?
With leave to amend, the plaintiff gets time to file an amended pleading. Without leave, the claim ends. The court's order controls the next deadline.
Can a demurrer and motion to strike be filed together?
Yes, when a pleading has both legally deficient causes of action and specific improper matter. They must be noticed and heard together, and meet-and-confer, timing, and formatting rules still apply.
