45 calendar days from service of the verified responses, extended by the method of service. CCP §§ 2030.300(c), 2031.310(c), 2033.290(c)
What catches people out: Forty-five days from service of the verified responses, and it is a jurisdictional outer limit rather than a deadline a court can relieve you from.
The clock runs 45 days from service of the verified responses, extended by the method of service. It is the hardest deadline in California discovery practice: miss it and the right to move is gone, because the 45 days is treated as jurisdictional rather than as a time limit the court may extend for good cause.
The word verified is load-bearing. Unverified responses containing anything other than objections are treated as no responses at all, which means the 45-day clock has not started and the correct motion is one to compel initial responses rather than further responses. Getting that distinction wrong is how practitioners file the wrong motion and then find the right one is time-barred.
The parties may extend the 45 days by written agreement, and doing so is routine and sensible. Get it in writing, and make sure the writing identifies the responses and the new date, because an informal extension that cannot be proved is worth nothing when the opposing party later argues the motion is late.
A separate statement is required, and a motion filed inside the 45 days without one is still vulnerable. The deadline and the papers are separate problems, and both have to be right.
What the statute does not say on its face
- The 45-day limit is mandatory, and an untimely motion must be denied. Courts describe it as jurisdictional, but with a qualification: it “is not ‘jurisdictional’ in the fundamental sense, but is only ‘jurisdictional’ in the sense that it renders the court without authority to rule on motions to compel other than to deny them.” (Sexton v. Superior Court (1997) 58 Cal.App.4th 1403, 1410; see Standon Co. v. Superior Court (1990) 225 Cal.App.3d 898 [“at least quasi-jurisdictional”]; Weinstein v. Blumberg (2018) 25 Cal.App.5th 316 [trial court may grant relief from the deadline].)
- Each of §§ 2030.300(c), 2031.310(c), and 2033.290(c) permits the parties to extend the 45 days “on or before any specific later date to which the [parties have] agreed in writing.” A written agreement therefore displaces the calculated date.
- The 45 days are calendar days, and electronic service of the response adds two court days: the deadline is “45 calendar days plus 2 court days.” (Golf & Tennis Pro Shop, Inc. v. Superior Court (2022) 84 Cal.App.5th 127, applying Code Civ. Proc., § 1010.6(a)(4)(B).)
- The clock runs from service of the verified response or any supplemental verified response; where a response contains substantive answers requiring verification, the period does not begin until the verification is served, while an objection-only response starts the clock on service without verification. (Ibid.)
- A meet-and-confer declaration is required (§ 2016.040).
- Must also be HEARD before the discovery motion cutoff, 15 days before trial (§ 2024.020(a)).
Then the hearing clock starts
Filing on time is half of it. The hearing itself runs on CCP § 1005(b): 16 court days of notice before the hearing, opposition 9 court days before, reply 5 court days before. Electronic service pushes the moving papers to 18 court days. All of it counts backward across weekends and California court holidays, which is where most miscounts happen. The civil motion deadline calculator does both halves at once.
Common questions
How long do you have to file a motion to compel further responses in California?
45 calendar days from service of the verified responses, under CCP §§ 2030.300(c), 2031.310(c), 2033.290(c). Calendar days count weekends and holidays; if the last day lands on one, the deadline rolls to the next court day.
Does the method of service extend the motion to compel further responses deadline?
Yes. Service extensions apply to this period, so the date moves depending on whether the triggering papers went out personally, by mail, by overnight delivery or electronically. The calculator applies the right one once you pick the method.
Can the motion to compel further responses deadline be extended?
The parties may agree in writing to a specific later date, which displaces this deadline (§§ 2030.300(c), 2031.310(c), 2033.290(c)). Nothing else extends it.
When are the opposition and reply due on a motion to compel further responses?
Opposition is due 9 court days before the hearing and the reply 5 court days before, under Code of Civil Procedure section 1005(b). Both are court days and both count backward from the hearing across weekends and California court holidays.
What catches people out on the motion to compel further responses deadline?
