These rules apply regardless of what claim is being demurred.

The sole question is whether the facts as pleaded state a valid cause of action — not whether plaintiff can prove the facts, not whether the facts are likely, not whether you have a good defense. (Kerivan v. Title Ins. & Trust Co. (1983) 147 Cal.App.3d 225, 229.)

California does not apply the federal Twombly/Iqbal plausibility standard. California requires that the complaint state ultimate facts sufficient to give notice of the issues — not a factually detailed account of everything plaintiff can prove. (Thomas v. Regents of University of Cal. (2023) 97 Cal.App.5th 587, 605; Youngman v. Nevada Irrigation Dist. (1969) 70 Cal.2d 240, 245.) Federal district court opinions on pleading sufficiency are not binding and are often not persuasive. (People v. Avena (1996) 13 Cal.4th 394, 431.)

Less specificity is required when the facts are predominantly in the defendant's knowledge. (Redfearn v. Trader Joe's Co. (2018) 20 Cal.App.5th 989, 996.)

Evidentiary facts found in exhibits attached to the complaint are considered on demurrer and control over inconsistent allegations in the complaint body. (Frantz v. Blackwell (1987) 189 Cal.App.3d 91, 94.)

Meet and confer is mandatory under CCP § 430.41.

Before filing a demurrer in California, the demurring party must meet and confer — in person, by telephone, or by video conference — at least five days before the responsive pleading is due. The Legislature added the requirement in 2016 because a large fraction of first-round pleading defects are curable by amendment and were clogging the demurrer calendar; if a phone call can resolve the defect, the court would rather not read the motion. The meet-and-confer must identify with legal support the specific grounds for the demurrer and give the plaintiff an opportunity to amend. Failure to comply does not by itself require overrule, but the court can continue the hearing to force compliance, and judges notice.

Code Civ. Proc. § 430.41(a); Code Civ. Proc. § 430.41(a)(4) (declaration required).

A demurrer does not lie to part of a cause of action.

You cannot demur to "the portion of the fraud claim based on misrepresentation A" while leaving the rest of the count untouched. The demurrer is a sufficiency test on the cause of action as a whole — letting parties cherry-pick individual theories within a count would turn one motion into many and produce piecemeal rulings the court has to reconcile later. Courts overrule partial demurrers routinely. If you want to knock out one theory inside a count, the procedural tool is a motion to strike under CCP § 436, not a partial demurrer.

PH II, Inc. v. Superior Court (1995) 33 Cal.App.4th 1680, 1682; Code Civ. Proc. § 430.50(a).

Each ground must appear in a separate, labeled paragraph.

California Rule of Court 3.1320(a) requires the demurrer itself — not the memorandum — to set out each ground in a separate paragraph stating whether it is addressed to the entire complaint or to specified causes of action, and identifying the ground with statutory citation. The court rules on the demurrer document, not on the brief; the separate-paragraph format is how the judge knows exactly which statutory ground is being ruled on for each count, and how the clerk's order later tracks cleanly to the ruling. Demurrers that blend grounds into narrative prose can be disregarded for that reason alone.

Cal. Rules of Court, rule 3.1320(a); Code Civ. Proc. § 430.60.

A demurrer tests the face of the complaint only.

A demurrer tests the sufficiency of the pleading as it stands — it does not consider evidence, declarations, contracts not attached to the complaint, or matters outside the four corners of the pleading (other than matters subject to judicial notice). The demurrer is a pre-discovery, pre-evidence screen: disputed facts get resolved on summary judgment or at trial, not on the pleadings. Demurrers that smuggle in attorney declarations, correspondence, or contract text the complaint does not incorporate by reference are routinely overruled for that reason alone.

SKF Farms v. Superior Court (1984) 153 Cal.App.3d 902, 905; Blank v. Kirwan (1985) 39 Cal.3d 311, 318.

Judicial notice covers existence, not truth.

A court may take judicial notice that a document exists, that a court filing was made, or that a statute has a certain text — but it does not take judicial notice of the truth of disputed factual assertions inside those documents. Both movants and opponents overreach here: filing a request for judicial notice that asks the court to accept, as true, the disputed contents of a letter, declaration, or document drawn from another proceeding. The application is denied, and the argument built on it fails.

Evid. Code § 452, subd. (d); Herrera v. Deutsche Bank National Trust Co. (2011) 196 Cal.App.4th 1366, 1375; Fremont Indemnity Co. v. Fremont General Corp. (2007) 148 Cal.App.4th 97, 113.

Factual disputes belong on summary judgment, not demurrer.

On demurrer, the court accepts all properly pleaded material facts as true and draws reasonable inferences in the plaintiff's favor, no matter how improbable. Arguments that the complaint is factually wrong — that the contract said something else, that the events happened differently, that the plaintiff is mistaken about dates — are categorically outside the demurrer's scope. That argument belongs in a motion for summary judgment after discovery.

Blank v. Kirwan (1985) 39 Cal.3d 311, 318; Del E. Webb Corp. v. Structural Materials Co. (1981) 123 Cal.App.3d 593, 604 (no matter how unlikely or improbable).

Silence in the opposition brief is a concession.

If the demurrer attacks six theories and the opposition defends only three, the court treats the unaddressed three as conceded — and sustains on those grounds without further analysis. Courts do not build the plaintiff's argument; if the opposition doesn't defend a theory, the court has no basis to overrule on it and treats silence as acquiescence. This was the single largest driver of SUSTAIN outcomes in the corpus. It is also the easiest failure to prevent.

Glendale Redevelopment Agency v. Parks (1993) 18 Cal.App.4th 1409, 1424; Herzberg v. County of Plumas (2005) 133 Cal.App.4th 1, 20.

Leave to amend is liberally granted on first demurrer.

California policy favors resolution on the merits, and leave to amend is almost always granted on a first pleading challenge unless the defect is plainly incurable. Movants who ask for "sustain without leave" on a first demurrer usually get rebuffed. The correct ask on a first demurrer is generally "sustain with leave"; "without leave" is reserved for situations where the face of the complaint shows the claim cannot be stated as a matter of law (e.g., the statute of limitations has run and the discovery rule is foreclosed on the face of the pleading).

Goodman v. Kennedy (1976) 18 Cal.3d 335, 349; City of Stockton v. Superior Court (Civic Partners Stockton, LLC) (2007) 42 Cal.4th 730, 747; Blank v. Kirwan (1985) 39 Cal.3d 311, 318.

The sham pleading doctrine catches contradictory amendments.

After a demurrer is sustained with leave, a plaintiff cannot file an amended pleading that contradicts material allegations from the original pleading without explaining the contradiction. The rule exists to prevent parties from using the amendment process to relitigate the facts: leave to amend is granted so plaintiffs can cure defects, not so they can walk back allegations that were fatal the first time. The court can treat the inconsistent allegations as sham and disregard them — which often means the same demurrer succeeds on the amended pleading. Amend truthfully: plead around the defect by adding facts, not by denying facts previously alleged.

Deveny v. Entropin, Inc. (2006) 139 Cal.App.4th 408, 425–426; Vallejo Development Co. v. Beck Development Co. (1994) 24 Cal.App.4th 929, 946.

Unpublished federal district court opinions are persuasive at best.

Citing a Northern District or Central District opinion as if it binds a California state court is a tell. California state courts are not bound by lower federal court decisions — even published ones — and unpublished federal district orders carry almost no weight. In our corpus, the court discounted the authority by name in eight separate proceedings.

People v. Bradley (1969) 1 Cal.3d 80, 86; Raven's Cove Townhomes, Inc. v. Knuppe Development Co. (1981) 114 Cal.App.3d 783, 804.

A demurrer knocks out the scary claims, not the case.

The claims that carry the real defense cost are the ones with fee-shifting statutes, punitive damages, and treble or statutory damages — not the ordinary-damages counts. FEHA and § 1102.5 carry prevailing-party fees; Tameny supports punitives; § 3294 exposes malice/oppression/fraud claims to punitives; § 1021.5 opens private-attorney-general fees; § 3345 trebles damages in senior/disabled cases. A demurrer that eliminates the punitive-damage claim or the fee-shifting statutory count changes the settlement calculus even if the underlying tort survives. A motion to strike the punitive-damages claim produces the same shift from the motion-to-strike side — punitive damages stricken with leave, case continues, but the defense pressure recalibrates.

Civ. Code § 3294 (punitive damages standard); Code Civ. Proc. § 1021.5 (private attorney general fees); Civ. Code § 3345 (treble damages for senior/disabled victims); Gov. Code § 12965 (FEHA prevailing-party fees); Lab. Code § 1102.5, subd. (j) (whistleblower attorney's fees).

A demurrer defines the discovery perimeter.

This is the point most clients underestimate. Discovery is statutorily limited to "any matter... relevant to the subject matter involved in the pending action" — CCP § 2017.010. "The pending action" means the operative pleading. Every count eliminated on demurrer is a topic the defendant does not have to produce on, a deposition line the defendant does not have to prepare for, and a category of ESI not pulled into the review. A demurrer that sustains without leave on two of six counts is a demurrer that shrinks the discovery universe by roughly a third — often the most expensive third.

Tactically, this matters later in the case. When the plaintiff eventually moves to compel discovery reaching demurred-out claims, the defense plays the order: quote the sustained-without-leave ruling in the opposition and attach it as an exhibit, and anchor the scope objection on § 2017.010. For the full opposition play, see the paired MTC Opposition Watchpoint on scope.

Code Civ. Proc. § 2017.010 (discovery scope).

The first demurrer is the free swing. The third is the finisher.

City of Stockton v. Superior Court (2007) 42 Cal.4th 730, 747 ties the "liberality" rule explicitly to plaintiffs who "have not yet had opportunity to amend in response to a demurrer." That generosity attaches to the original complaint. By the second or third amendment on the same defect, the corpus shows courts invoking IIG Wireless v. Yi (denying leave where "the facts stated do not constitute a cause of action"), Melican v. Regents (unwarranted delay alone justifies denial), and Miles v. City of Los Angeles (denial appropriate "after years of litigation where the facts were long known"). Futility hardens into an affirmative ground for denial, not a fallback.

The procedural trap that closes the loop: once a demurrer is sustained without leave to amend on a count, the only path back is a motion for reconsideration under CCP § 1008 — with its statutory limits on timing and on what qualifies as "new or different facts." A later Motion for Leave to Amend under Rule 3.1324 cannot be used as a back door around a without-leave ruling; that path closes the moment the without-leave order is entered.

Taken together: the win from a California demurrer is the shape of the case that goes forward — which claims, which damages theories, which discovery, which procedural posture on amendment. Measure the demurrer against that yardstick, not against the "whole case dismissed" yardstick.

City of Stockton v. Superior Court (Civic Partners Stockton, LLC) (2007) 42 Cal.4th 730, 747; IIG Wireless, Inc. v. Yi (2018) 22 Cal.App.5th 630, 654; Melican v. Regents of University of California (2007) 151 Cal.App.4th 168, 175; Miles v. City of Los Angeles (2020) 56 Cal.App.5th 728, 739; Code Civ. Proc. § 1008 (reconsideration).

Elements: (1) existence of a contract; (2) plaintiff's performance or excuse for nonperformance; (3) defendant's breach; (4) resulting damages. (Oasis West Realty, LLC v. Goldman (2011) 51 Cal.4th 811, 821.)

The complaint must state on its face whether the contract is written, oral, or implied by conduct. (Code Civ. Proc. § 430.10(g); Otworth v. Southern Pac. Transportation Co. (1985) 166 Cal.App.3d 452, 458-459.) This is a hard formal requirement — an otherwise well-pleaded contract claim can be demurred for omitting this.

Plaintiff may plead the legal effect of the contract rather than its precise terms. (McKell v. Washington Mutual, Inc. (2006) 142 Cal.App.4th 1457, 1489.) But if you plead legal effect, you must be comprehensive — no gaps.

Corporate agents acting for and on behalf of a corporation cannot be held personally liable for breach of a contract made on the corporation's behalf. (Strawn v. Morris, Polich & Purdy, LLP (2019) 30 Cal.App.5th 1087, 1092.)

Moving party: Check whether the complaint identifies the contract type (written/oral/implied). Check whether the substance of the relevant terms is alleged — not just that 'an agreement existed.' For oral contracts, are the material terms definite enough to measure performance? Is the defendant a corporate agent sued individually?

Opposing party: Plead the type of contract explicitly in the first paragraph of the cause of action. Identify the specific allegation that establishes each material term. Legal-effect pleading is sufficient but must cover the substance of each relevant term, performance, and the specific breach.

Watch for: The § 430.10(g) trap. Attorneys routinely plead 'plaintiff and defendant entered into a contract' without saying whether it was written or oral. One sentence fixes this. Missing it loses the demurrer.

The implied covenant protects the express covenants of the contract — it cannot impose substantive duties or limits beyond what the contract establishes. (Berlanga v. University of San Francisco (2024) 100 Cal.App.5th 75, 88.) Without a contractual relationship, there is no implied covenant claim.

The covenant requires the parties not to prevent the other from receiving the contract's benefits, and to act in good faith in exercising discretionary powers. (Careau & Co. v. Security Pacific Business Credit, Inc. (1990) 222 Cal.App.3d 1371, 1393-1395.)

Moving party: Does the implied covenant claim allege conduct that is independent of the breach of contract claim? If the implied covenant claim rests on identical acts as the breach of contract claim, it adds nothing and the demurrer should be sustained. (Careau, supra, 222 Cal.App.3d at 1395.) Does the plaintiff seek to use the covenant to add obligations the contract doesn't contain? Is there a contract at all?

Opposing party: The implied covenant and breach of contract claims can coexist if based on different conduct. Identify clearly in the complaint which acts constitute breach of express terms and which constitute breach of the covenant. If the demurrer argues the claims are duplicative, show how the conduct supporting each differs.

Watch for: Courts sustain demurrers to implied covenant claims that are word-for-word identical to the breach of contract claim with 'implied covenant' substituted. Keep these claims factually distinct or combine them.

The threshold question before filing a SOL demurrer: Does the complaint establish, on its face, that the claim is time-barred? If answering this requires resolving a factual dispute — when did the attorney-client relationship end, when did plaintiff discover the injury, when did the clock start — that is a summary judgment question, not a demurrer question. Filing a SOL demurrer that requires factual findings educates the other side for free.

Discovery rule: Plaintiff whose complaint shows on its face that the claim is time-barred must specifically plead: (1) the time and manner of discovery; and (2) the inability to have made earlier discovery despite reasonable diligence. Conclusory allegations of tolling will not withstand demurrer. (Fox v. Ethicon Endo-Surgery, Inc. (2005) 35 Cal.4th 797, 808.)

Key limitations periods:

• Defamation/slander: 1 year
• Fraud: 3 years (Code Civ. Proc. § 338, subd. (d))
• Warranty: 4 years from delivery, unless warranty explicitly extends to future performance (Com. Code § 2725(2); Mexia v. Rinker Boat Co., Inc. (2009) 174 Cal.App.4th 1297)
• Legal malpractice (§ 340.6): 1 year from discovery, or 4 years from date of actionable malpractice — whichever is first. Tolled during attorney's continuing representation in the specific subject matter. Applies to all attorney misconduct except actual fraud, including breach of contract claims whose merits depend on proof of a professional obligation violation. (Lee v. Hanley (2015) 61 Cal.4th 1225, 1236-1237.) Transition work does not extend tolling. (Shaoxing City Maolong Wuzhong Down Products, Ltd. v. Keehn & Associates, APC (2015) 238 Cal.App.4th 1031, 1039.)

Moving party: Does the complaint show on its face — based only on what's in the complaint — that the statute has run? If tolling is alleged: is it alleged with specific facts or just labels? If there is any ambiguity about when the clock started, save this argument for summary judgment.

Opposing party: If the defendant's SOL argument requires the court to determine when the clock started based on disputed or unclear facts: make this point directly. 'The date defendant relies upon is not established on the face of the complaint. This is a factual dispute the court cannot resolve on demurrer.' (Worthington v. Rusconi (1994) 29 Cal.App.4th 1488, 1497.) If you need tolling: plead the discovery rule facts specifically — date of discovery, how you discovered it, what you did before that and why it didn't reveal the claim sooner.

The UCL is written in the disjunctive — three separate varieties: unlawful, unfair, or fraudulent. (Cel-Tech Communications, Inc. v. Los Angeles Cellular Telephone Co. (1999) 20 Cal.4th 163, 180.) A complaint need only state facts supporting one of the three. The 'unlawful' prong applies broadly to anything that can properly be called a business practice that is at the same time forbidden by law. (People v. E.W.A.P., Inc. (1980) 106 Cal.App.3d 315, 318-319.)

UCL claims must be pleaded with reasonable particularity — not fraud-level specificity, but not pure conclusory allegations either. (Gutierrez v. Carmax Auto Superstores Cal. (2018) 19 Cal.App.5th 1234, 1265.)

Moving party: Is the UCL claim purely derivative of other claims that themselves fail? If the predicate 'unlawful' or 'unfair' acts are stated only in other causes of action that are being demurred, the UCL claim may fall with them. Is the complaint challenging the remedy (damages) rather than the claim itself? If so, use a motion to strike, not a demurrer. (Venice Town Council, Inc. v. City of Los Angeles (1996) 47 Cal.App.4th 1547, 1561-1562.) Courts will overrule a demurrer that attacks only the damages prayer.

Opposing party: The UCL's disjunctive structure is your friend. Even if the 'fraudulent' prong is inadequately pleaded, 'unlawful' or 'unfair' may survive independently. If defendant demurs on remedy grounds: flag it — motion to strike is the right vehicle, not a demurrer. Ask for the demurrer to be overruled on this basis.

The play: Demurring party raises multiple grounds. Opposition brief addresses only some of them.

Why it matters: Failure to address a ground raised in the demurrer is treated as conceding it. (Westside Center Associates v. Safeway Stores 23, Inc. (1996) 42 Cal.App.4th 507, 534 fn. 10.) Courts will sustain a demurrer on a ground plaintiff never responded to — regardless of whether that ground would otherwise have merit.

If you're opposing: Address every ground raised in the demurrer — even briefly. If you have strong responses to grounds A, B, and C but the complaint has no good answer to D: address D and ask for leave to amend. A request for leave to amend on a weak ground is better than silence.

The play: Defendant demurs to attack a remedy, a damages prayer, or an allegation within a cause of action rather than the cause of action itself.

Why it fails: A demurrer attacks whether a cause of action is stated. A motion to strike attacks improper matter, a specific prayer, or an unavailable remedy. Using a demurrer to challenge only a damages prayer or remedy — rather than the claim itself — is the wrong procedural vehicle and will be overruled. (Venice Town Council, Inc. v. City of Los Angeles (1996) 47 Cal.App.4th 1547, 1561-1562; PH II, Inc. v. Superior Court (1995) 33 Cal.App.4th 1680, 1682.)

If you're opposing: Identify the wrong vehicle in the first paragraph of your opposition. The demurrer should be overruled on procedural grounds before the court reaches the merits.

If the demurrer is sustained with leave to amend:

Read the order precisely. Leave to amend authorizes fixing the specific defect identified — not reimagining the case. New causes of action require a separate motion for leave to amend under CRC 3.1324. (Zakk v. Diesel (2019) 33 Cal.App.5th 431, 456.) The amendment must be factually consistent with any matters of which the court has taken judicial notice.

If the demurrer is sustained without leave to amend:

The complaint is dismissed. The standard for no leave is high — the complaint must show on its face that it cannot be amended to state a valid claim. Denial of leave is an abuse of discretion unless the court can say amendment is impossible. This is rare. (City of Stockton v. Sup. Ct. (2007) 42 Cal.4th 730, 747; Goodman v. Kennedy (1976) 18 Cal.3d 335, 349.)

If the demurrer is overruled:

Defendant must answer. The issues raised in the demurrer are not waived — they can be raised again at summary judgment or trial. Overruling means the complaint states a claim. It does not mean the claim will succeed.

New arguments in the reply brief are forfeited.

Saving your strongest argument for the reply is a sophisticated-filer habit that loses California cases. Raising a point for the first time on reply deprives the opposition of the chance to respond, and courts routinely treat the argument as waived — not merely disfavored. This is one of the most consistent forfeiture rules in the corpus.

American Drug Stores, Inc. v. Stroh (1992) 10 Cal.App.4th 1446, 1453; Reichardt v. Hoffman (1997) 52 Cal.App.4th 754, 764–765.
