Moving to quash service in California: file before you plead, and keep 10 days for the writ

California does not use a Rule 12(b)(2) motion. The vehicle is a motion to quash service of summons under CCP 418.10, and it comes with its own timetable, its own extension of the pleading deadline, and a writ-review step that disappears the moment you file an answer.

What the motion can do

CCP 418.10(a): a defendant, on or before the last day of their time to plead — or within any further time the court may for good cause allow — may serve and file a notice of motion for one or more of:

(1) To quash service of summons on the ground of lack of jurisdiction of the court over him or her. (2) To stay or dismiss the action on the ground of inconvenient forum. (3) To dismiss the action pursuant to the applicable provisions of Chapter 1.5 (commencing with Section 583.110) of Title 8.

Three purposes in one motion: personal jurisdiction, forum non conveniens, and delay-in-prosecution dismissal. They may be combined.

"On or before the last day of his or her time to plead" — for an ordinary summons that is 30 days after service, since CCP 412.20(a)(3) requires the summons to direct a written response "within 30 days after summons is served."

The notice, and the hearing date

CCP 418.10(b) sets two requirements that are easy to get wrong together:

The notice shall designate, as the time for making the motion, a date not more than 30 days after filing of the notice. The notice shall be served in the same manner, and at the same times, prescribed by subdivision (b) of Section 1005.

So the hearing must be within 30 days of filing — and the notice must give the 16 court days CCP 1005(b) requires, plus any service extension (five calendar days for in-state mail, ten for out-of-state within the United States, twenty outside it, two for overnight or fax).

Sixteen court days is roughly 22 calendar days. That leaves a narrow band: too early and you violate CCP 1005(b), too late and you exceed the 30 days. Reserve the hearing date before you finalise the notice.

What filing the motion buys you

The rest of CCP 418.10(b):

The service and filing of the notice shall extend the defendant's time to plead until 15 days after service upon him or her of a written notice of entry of an order denying his or her motion, except that for good cause shown the court may extend the defendant's time to plead for an additional period not exceeding 20 days.

Three things follow.

The pleading deadline is suspended while the motion is pending. You are not in default.

The new deadline runs from service of written notice of entry of the denial — not from the hearing, and not from the minute order.

Fifteen days, extendable by 20 more on good cause. Compare Washington's CR 12(a), which gives 10 days from notice of the court's action with no stated extension.

The 10-day writ — and why pleading kills it

CCP 418.10(c) is the provision that makes the sequencing matter:

If the motion is denied by the trial court, the defendant, within 10 days after service upon him or her of a written notice of entry of an order of the court denying his or her motion, or within any further time not exceeding 20 days that the trial court may for good cause allow, and before pleading, may petition an appropriate reviewing court for a writ of mandate to require the trial court to enter its order quashing the service of summons…

Read the two conditions together. You have 10 days, and you must not yet have pleaded.

That produces a real tension with subdivision (b), which gives you 15 days to plead. Both clocks start on the same event — service of written notice of entry of the denial — and the shorter one closes first. A defendant who answers on day 12, comfortably inside the pleading deadline, has given up the writ.

If you are considering writ review, calendar 10 days, not 15, and do not file the answer first.

Where a quash motion sits among the alternatives

California splits work that Rule 12 consolidates:

The demurrer guide on this site covers the pleading-sufficiency route.

How service is made — and what to check

A motion to quash on service grounds turns on which method was used, and each has its own completion rule.

Personal delivery — CCP 415.10. Service "is deemed complete at the time of such delivery." The date of delivery "shall be entered on or affixed to the face of the copy of the summons at the time of its delivery. However, service of a summons without such date shall be valid and effective."

So a missing date is not a defect worth moving on — the statute says so.

Substituted service — CCP 415.20. In lieu of personal delivery on the persons specified in CCP 416.10 through 416.50, a summons may be served "by leaving a copy … during usual office hours in the person's office or, if no physical address is known, at the person's usual mailing address, other than a United States Postal Service post office box, with the person who is apparently in charge," and by thereafter mailing a copy by first-class mail to the place where the copies were left. Where service is made at a mailing address, it must be left with a person at least 18 years of age, "who shall be informed of the contents."

Service of a summons in this manner is deemed complete on the 10th day after the mailing.

And for individuals — subdivision (b): substituted service at the dwelling house, usual place of abode, usual place of business, or usual mailing address is available only "if a copy of the summons and complaint cannot with reasonable diligence be personally delivered."

Reasonable diligence is the element to test. Substituted service without prior attempts at personal delivery is the most common ground for a successful motion to quash.

Notice and acknowledgment — CCP 415.30. A summons may be served by first-class mail together with two copies of the statutory notice and a postage-prepaid return envelope. The statute prints the form, which warns that failure to complete and return it within 20 days may make the recipient liable for the expenses of serving in another manner.

Section 415.30 provides that this summons is deemed served on the date of execution of an acknowledgment of receipt of summons.

Mail alone does not accomplish service under this section. Without a signed acknowledgment there is no service — only a cost-shifting risk to the person who ignored it.

Out-of-state — CCP 415.40. A summons may be served on a person outside California in any manner provided by the article, or "by sending a copy … by first-class mail, postage prepaid, requiring a return receipt." Service by this form of mail "is deemed complete on the 10th day after such mailing."

Publication — CCP 415.50. Available on affidavit satisfying the court that the party "cannot with reasonable diligence be served in another manner" specified in the article, and that either a cause of action exists against them or they are a necessary or proper party, or that they claim an interest in property in the state.

The court "shall order the summons to be published in a named newspaper, published in this state, that is most likely to give actual notice," and where the party is out of state may also order publication outside California. The order "shall direct that a copy of the summons, the complaint, and the order for publication be forthwith mailed to the party if his or her address is ascertained before expiration of the time prescribed for publication."

The three-year service deadline

CCP 583.210 imposes an outer limit that operates independently of any motion:

(a) The summons and complaint shall be served upon a defendant within three years after the action is commenced against the defendant. For the purpose of this subdivision, an action is commenced at the time the complaint is filed. (b) Proof of service of the summons shall be filed within 60 days after the time the summons and complaint must be served.

Three years to serve, and 60 days after that to file proof. This is the "applicable provisions of Chapter 1.5" that CCP 418.10(a)(3) lets a defendant invoke by motion to dismiss.

Note how differently other jurisdictions treat this: Federal Rule 4(m) gives 90 days, and Oregon's ORCP 7 63 days. California's three years is by far the longest, and it interacts with the five-year rule in CCP 583.310 — a plaintiff who uses most of the three years to serve has little of the five left to get to trial. The five-year rule guide covers that.

If a default has already been entered

Where service never produced actual notice and a default or default judgment is already in place, the motion to quash is not the tool. CCP 473.5 is.

The deadline — subdivision (a): where "service of a summons has not resulted in actual notice to a party in time to defend the action and a default or default judgment has been entered," the party may move to set it aside and for leave to defend, "within a reasonable time, but in no event exceeding the earlier of:

(i) two years after entry of a default judgment against the party; or (ii) 180 days after service on the party of a written notice that the default or default judgment has been entered.

Whichever is earlier — so a plaintiff who serves written notice of the default starts a 180-day clock that can close long before the two years.

What the motion must contain — subdivision (b): a hearing date prescribed by CCP 1005(b); an affidavit showing under oath that the party's lack of actual notice in time to defend was not caused by the party's avoidance of service or inexcusable neglect; and, served and filed with the notice, a copy of the answer, motion, or other pleading proposed to be filed.

That proposed pleading requirement matches CCP 473(b) and Oregon's ORCP 71 B(1). A motion without it is incomplete.

The guide on setting aside a California default covers CCP 473 and 473.5 in full.

How California compares

A short checklist

1. Calendar the last day to plead — 30 days from service under an ordinary California summons. The motion is due on or before it.
2. Reserve the hearing first. It must be within 30 days of filing and still give 16 court days' notice plus any service extension.
3. Combine what you have — jurisdiction, forum non conveniens and delay-in-prosecution can go in one motion.
4. Test the service method against its own statute. Substituted service needs reasonable diligence; notice-and-acknowledgment needs a signed acknowledgment; publication needs an affidavit and a most-likely-to-give-actual-notice newspaper.
5. Do not move on a missing delivery date. CCP 415.10 says service without it is still valid.
6. Check the three years. Service outside CCP 583.210 is its own ground for dismissal by motion.
7. If the motion is denied and you want writ review, calendar 10 days — not 15 — and do not plead. Pleading forfeits the writ.
8. If a default is already entered and you never had actual notice, use CCP 473.5, watch the earlier of two years and 180 days, and attach the proposed pleading with the required affidavit.
