When must California discovery motions be heard?

The initially scheduled trial date

Identify the actual hearing availability. Filing or serving a motion by this date does not establish that the motion was heard.

Responsible actor. The party arranging the hearing of an ordinary discovery motion. Use the initially scheduled trial and a nonexpert discovery motion, with no court leave for a later hearing or reopened discovery. Only the disclosed component is supported. Additional actual closures, altered orders and excluded service methods require separate review. A closed base boundary is refused because this preset does not apply the legally applicable final-day treatment.

1. Use the initially scheduled trial and a nonexpert discovery motion, with no court leave for a later hearing or reopened discovery. Only the disclosed component is supported. Additional actual closures, altered orders and excluded service methods require separate review. A closed base boundary is refused because this preset does not apply the legally applicable final-day treatment.
2. Exclude the established scheduled event and count backward 15 calendar days under CCP 12c. The displayed base boundary preserves the stated lead time. The preset applies no automatic adjustment when that boundary is closed; check the actual act and applicable holiday treatment before relying on it.
3. Check the actual judicial holidays, closures and statutory or court-ordered qualifications.
4. Obtain and conduct the hearing by the applicable cutoff while also satisfying the motion’s own notice, filing and response-based deadline.

CCP 12 excludes the triggering day for ordinary day periods. CCP 12a supplies the final judicial-holiday adjustment, including Saturdays and the CCP 135 holidays. CCP 12b addresses qualifying whole-day office closures. Court-day periods exclude intermediate Saturdays, Sundays and judicial holidays. Calendar-day periods include intermediate closed days. Rule 1.11 supplies Friday observance of a Saturday judicial holiday and Monday observance of a Sunday judicial holiday. The calendar includes Lincoln Day, March 31, Juneteenth, Native American Day and Thanksgiving Friday. It excludes Columbus Day and Good Friday as ordinary full judicial holidays. The observed New Year holiday on December 31, 2027 is confirmed in the county schedule. Actual additional closures require separate evidence.

These base components do not add mail, electronic, fax, express or overnight service time. CCP 1013 and 1010.6 identify eligible additions, service conditions and express exceptions. CCP 1005 supplies its own motion-delivery provisions and excludes CCP 1013 for its identified notices. New-trial and CCP 663a intention-notice filings do not receive the stated mail or electronic additions. Establish the actual service method and governing procedure before applying any addition. A summons-service completion event is not determined by the general document-service addition.

The official sections were reviewed, including the retained 2026 and operative-2027 CCP 473 and 415.20 editions. Publication coverage for day and court-day components begins January 1, 2026, or a later expressly stated section effective date. Year components begin no earlier than January 1, 2021, or the section’s later stated effective date, and assume the current reviewed branch applies. These are software coverage boundaries, not findings that an actual act is late. Displayed final dates are confined to the independently reviewed 2026 and 2027 judicial calendar. Closed backward base boundaries and closed minimum-deposition boundaries receive no computed or paid date because their exact adjustment is not implemented. Earlier editions, emergency measures, tolling, different service methods and actual additional closures require separate review.

Fictitious example

Use the initially scheduled trial and a nonexpert discovery motion, with no court leave for a later hearing or reopened discovery. Only the disclosed component is supported. Additional actual closures, altered orders and excluded service methods require separate review. A closed base boundary is refused because this preset does not apply the legally applicable final-day treatment. The disclosed component, effective personal or specified nonmail service and no changed order.

Fictitious facts within the stated coverage. This is the disclosed component, not a determination of legal accrual, effective service, court action or entitlement. No tolling, different service addition, altered order or additional closure is assumed. Closed unsupported base branches receive no computed date.

Separate motion deadline

For further interrogatory responses, CCP 2030.300(c) separately controls timely notice after the verified response. Both conditions require attention.

Expert motion

CCP 2024.030 gives the distinct ten-day-before-trial expert-discovery hearing cutoff.

Court permission

CCP 2024.050 permits leave for later discovery or hearings on the described motion.

Service methods and distinct statutory additions

These base components do not add mail, electronic, fax, express or overnight service time. CCP 1013 and 1010.6 identify eligible additions, service conditions and express exceptions. CCP 1005 supplies its own motion-delivery provisions and excludes CCP 1013 for its identified notices. New-trial and CCP 663a intention-notice filings do not receive the stated mail or electronic additions. Establish the actual service method and governing procedure before applying any addition. A summons-service completion event is not determined by the general document-service addition.

• Use the initially scheduled trial and a nonexpert discovery motion, with no court leave for a later hearing or reopened discovery. Only the disclosed component is supported. Additional actual closures, altered orders and excluded service methods require separate review. A closed base boundary is refused because this preset does not apply the legally applicable final-day treatment.
• The base calculation does not resolve the excluded comparisons or establish that the responsible actor completed the required act.

• The initially scheduled trial date
• Identify the actual hearing availability. Filing or serving a motion by this date does not establish that the motion was heard.
• For further interrogatory responses, CCP 2030.300(c) separately controls timely notice after the verified response. Both conditions require attention.
• CCP 2024.030 gives the distinct ten-day-before-trial expert-discovery hearing cutoff.
• CCP 2024.050 permits leave for later discovery or hearings on the described motion.
• Obtain and conduct the hearing by the applicable cutoff while also satisfying the motion’s own notice, filing and response-based deadline.
• Where filing is required, distinguish accepted filing from service. CCP 1010.6(e)(3) gives the stated same-court-day treatment to qualifying electronic court receipt between 12:00 a.m. and 11:59:59 p.m.; noncourt-day receipt is deemed on the next court day. Its confirmation and rejection provisions still matter. Preserve the accepted filing confirmation, effective service evidence and applicable local requirements. Court-office paper availability and case-specific orders require separate review. This does not turn a service-only response, court determination, completed discovery or trial commencement into a filing-only act.
