Prior demurrer to this pleading?
Affects CCP § 430.41(b) waiver risk.
Per CCP §§ 430.40, 430.41, 1005(b), 1010.6, 1013. Weekends and CA court holidays excluded from court-day counts. Verify with your court's local rules before filing.
CCP § 430.41(b) — Waiver trap
You cannot demur on a ground you could have raised in a prior demurrer to an earlier version of this pleading. If the ground was available before, it is waived. Identify specifically which grounds are new — raised for the first time against this amended pleading — before filing.
Select your role to see your checklist.
The corpus findings and key statutes below apply to both sides.
1 — Timing
File within 30 days of service of the pleading being attacked (CCP § 430.40(a)).
Add the service extension that matches how the pleading was served on you -- one method per line:
- Mail, place of mailing and address both in California: +5 calendar days (CCP § 1013(a)). Mail from or to an address outside California but within the U.S.: +10 calendar days; outside the U.S.: +20 calendar days (same subdivision).
- Express Mail or another overnight delivery method: +2 court days (CCP § 1013(c)).
- Fax (permitted only where the parties agreed and confirmed the agreement in writing): +2 court days (CCP § 1013(e)).
- Electronic service: +2 court days (CCP § 1010.6(a)(3)(B)).
Do not borrow the motion-notice rule: CCP § 1005(b) adds +2 calendar days for fax/express mail/overnight service of motion papers against the 16-court-day hearing-notice period, and states that § 1013 does not apply to papers governed by § 1005. The 30-day responsive-pleading deadline is governed by § 1013, not § 1005(b).
If you cannot meet and confer at least 5 days before the responsive pleading is due, the demurring party is granted an automatic 30-day extension by filing and serving, on or before the date the demurrer would be due, a declaration under penalty of perjury stating that a good faith attempt to meet and confer was made and explaining why the parties could not meet and confer (CCP § 430.41(a)(2)).
CCP § 430.41(b) trap: If a demurrer to an earlier version of the pleading was sustained and the pleading was then amended, you cannot demur to the amended pleading on grounds that could have been raised by demurrer to the earlier version. Identify which grounds are new -- raised for the first time against this amended pleading -- before filing.
2 — Meet and Confer Corpus #1 failure
Meet and confer at least 5 days before the date the responsive pleading is due (CCP § 430.41(a)(2)). If you cannot, file and serve the § 430.41(a)(2) declaration on or before the demurrer due date to get the automatic 30-day extension.
Must be in person, by telephone, or by video conference (CCP § 430.41(a)). Email is not one of the listed methods, so an email exchange alone does not satisfy the statute.
What the conversation must cover: the demurring party identifies all of the specific causes of action it believes are subject to demurrer and identifies, with legal support, the basis of the deficiencies; the party who filed the pleading provides legal support for its position that the pleading is sufficient, or explains how it could be amended to cure the defect (CCP § 430.41(a)(1)).
If opposing counsel won't respond: send a written meet-and-confer request and document it. If the other side fails to respond or otherwise fails to meet and confer in good faith, you may file the demurrer with a declaration saying so (§ 430.41(a)(3)(B)).
File and serve with the demurrer a declaration stating either (§ 430.41(a)(3)):
(A) the means by which you met and conferred with the party who filed the pleading, and that the parties did not reach an agreement resolving the objections raised in the demurrer; or
(B) that the party who filed the pleading failed to respond to your meet-and-confer request or otherwise failed to meet and confer in good faith.
What the statute does not do: a court's determination that the meet-and-confer process was insufficient "shall not be grounds to overrule or sustain a demurrer" (§ 430.41(a)(4)). The declaration requirements are limited to (A) or (B) above; listing the date and the causes of action discussed is good practice, but the statute does not require it.
3 — Notice and Hearing Reservation
Reserve a hearing date before filing (through the court's online reservation system — check local rules for your courthouse).
Serve at least 16 court days before the hearing (CCP § 1005(b)) — note: court days, not calendar days.
Add service extensions to the 16-day window: mail within CA (+5 calendar days), overnight (+2 calendar days), electronic service (+2 court days per CCP § 1010.6(a)(3)(B)).
4 — What to File
Notice of demurrer and demurrer (the motion document itself, with grounds).
Memorandum of points and authorities (15-page limit — CRC 3.1113(d)).
Declaration re: meet and confer (required).
Request for judicial notice, if you are relying on judicially noticeable facts.
Proof of service.
5 — Format
Memorandum: 15 pages maximum (CRC 3.1113(d)).
Table of contents + table of authorities required if memorandum exceeds 10 pages (CRC 3.1113(f)).
Specify each ground under CCP § 430.10 — do not lump them together.
Your Deadlines
Opposition due: 9 court days before hearing (CCP § 1005(b)) + service extensions.
Reply due: 5 court days before hearing + service extensions.
Procedural Levers
M&C declaration is deficient? Raise it in your opposition. The court will likely continue rather than deny -- which costs your opponent time and may force a more substantive M&C that resolves issues before the next hearing.
Grounds already raised in a prior demurrer? CCP § 430.41(b) bars it. If the defendant is demurring on a ground they could have raised against the first complaint, it's waived. Cite the prior demurrer, identify the overlapping ground, and ask the court to deny without leave to re-demur on that ground.
Leave to amend: You hold the burden to show a reasonable possibility of curing the defect. Courts apply a liberality canon (City of Stockton v. Superior Court (2007) 42 Cal.4th 730). If you can articulate how you would amend, do so -- specifically. "Plaintiff could allege additional facts showing X" is more persuasive than a general request for leave.
Late opposition? File it anyway and lead with a short section explaining the delay and asking the court to exercise its CRC 3.1300(d) discretion. Courts that consider late papers almost always want to see that the lateness was addressed directly.
What Actually Kills Demurrers — Corpus Findings
Patterns from procedural failure rulings across 7 CA county courts. Listed in order of frequency.
Meet and confer failure
The most common failure, and it shows up in two distinct forms.
Inadequate conferral. Sending a letter and calling it done. Emailing without consent. Discussing issues generally without addressing the specific pleading defects. The statute requires a substantive conversation about the actual grounds.
Declaration too thin to prove it. The M&C happened but the declaration doesn't show it. Courts cannot evaluate compliance from a declaration that says only "counsel met and conferred."
"The Court notes Hall's declaration is silent as to any meet and confer efforts regarding the demurrer to the SAC. While the party may have met and conferred, there is no evidence of it in the record."
"The Court admonishes Defendant that in the future, it may continue the hearing on any demurrer in order to allow the parties to meet and confer."
What courts do: Usually a continuance, not an outright denial -- but it costs time and signals that you cut corners.
Untimely filing
Two distinct problems depending on what was late.
Late demurrer (the 30-day clock). Courts rarely exercise discretion here. If your demurrer is late, it is almost always denied. The clock runs from service of the pleading, with extensions for service method. Default does not revive a lapsed deadline.
Late opposition. Courts have discretion under CRC 3.1300(d) to consider or refuse a late opposition. They go both ways. "Three days late" in one ruling was considered; in another it was not. You cannot count on the court bailing you out.
"Plaintiff untimely filed her opposition on April 21, 2026, three days late. The Court has broad discretion to refuse to consider papers filed and served beyond the deadline without a prior court order finding good cause."
Missing declaration
Distinct from inadequate meet and confer. Here the declaration was simply never filed -- not inadequate, just absent.
"The Court notes Defendant failed to file a declaration as to any meet and confer efforts regarding the demurrer to the FAC."
This is a checklist failure. The M&C may have happened. The declaration just wasn't included in the filing package.
Insufficient notice period
Notice calculation errors -- most commonly forgetting to add service extension days to the 16-court-day window, or confusing court days with calendar days.
The math: if you serve electronically, you owe 16 court days + 2 court days = 18 court days minimum. Courts count from the date of service, not the date of filing.
No proof of service
The demurrer was filed; proof that it was served on all parties was not. Courts are strict. Even when the record shows service likely happened, an unfiled proof of service creates a problem.
