California Discovery Toolkit: Interrogatories, RFAs & RFPs Explained

Discovery is the engine of every California civil case. Properly crafted interrogatories, requests for admission (RFAs), and requests for production (RFPs) can make or break your litigation strategy—uncovering key facts, narrowing issues, and setting up dispositive motions. This toolkit explains each discovery tool under the California Code of Civil Procedure (CCP §§ 2030–2033), outlines response deadlines, and offers practical drafting tips. If you still have questions, book a free 15‑minute consultation to discuss your specific discovery needs.

Tools include depositions, interrogatories, RFAs, RFPs, subpoenas, and medical exams
30‑day response deadline (plus 5 days for mail) for most written discovery

Interrogatories — CCP §2030

What Are Interrogatories?

Written questions requiring sworn answers from the opposing party.

Limits & Types

Type	Limit	Form Number
Form Interrogatories	No numeric limit	Judicial Council Form DISC‑001
Special Interrogatories	35 (no subparts allowed; more with a declaration)	Custom drafted

Key Deadlines

Serve. Defendant: any time. Plaintiff: 10 days after service of summons on, or appearance by, that party, whichever is first
Respond within 30 days (mail adds 5 days)
Motion to compel further: 45 days after service of verified response (no 45‑day limit if no response)

Drafting Tips

Use plain language; avoid compound questions
Tie each interrogatory to a specific claim or defense
For form interrogatories, check only relevant boxes to avoid objections.

Requests for Admission (RFAs) — CCP §2033.010

Purpose

Narrow issues by having the opponent admit or deny facts, authenticity of documents, or legal conclusions.

Highlights

Limit of 35, not counting requests on genuineness of documents; more with a declaration (CCP §2033.030)
30‑day response deadline
Effect of Admission: Fact is conclusively established unless withdrawn
Cost‑of‑Proof Sanctions: Failure to admit can shift attorney's fees if the fact is later proven at trial

Requests for Production (RFPs) — CCP §2031

Scope

Documents, electronically stored information (ESI), tangible items, and site inspections.

Drafting Essentials

Describe with “reasonable particularity.”
Specify format for ESI (PDF, native, metadata).
Include a time frame (e.g., “from January 1, 2023 to present”).

Response Options

Agree to comply, object, or state inability to comply (with reasons).
Provide privilege log if withholding documents.

Meet‑and‑Confer Requirements

Mandatory before filing a motion to compel further responses (CCP §2016.040).
Must be a reasonable, good‑faith attempt in person, by telephone, or by videoconference (CCP §2016.040(a)).
Document efforts in the meet‑and‑confer declaration; attach any confirming letters.

Common Objections & How to Draft Them

Relevance — “Not reasonably calculated to lead to admissible evidence.”
Overbroad & Unduly Burdensome — scope or time frame too broad.
Privilege — attorney‑client, work product, trade secret.
Privacy — constitutional or statutory protections.
Vague & Ambiguous — unclear terms or definitions.

Tip: Always answer to the extent possible before objecting in full.

Motions to Compel Responses

Motion Type	Deadline	Use When
Motion to Compel Further Responses	45 days after service of verified responses	Responses are evasive or objections improper
Motion to Compel Initial Responses	No 45‑day limit	No responses served at all

Motion Type

Deadline

Use When

Motion to Compel Further Responses

45 days after service of

verified

responses

Responses are evasive or objections improper

Motion to Compel Initial Responses

No 45‑day limit

No responses served at all

Separate Statement required for motions to compel further responses (CRC 3.1345).
Monetary sanctions are mandatory against the losing side unless it acted with substantial justification or a sanction would be unjust.

Electronic Discovery (ESI) Considerations

CCP §2031.030(a)(2) — specify ESI format.
Claw‑back agreements to address inadvertent production.
Native vs. PDF — choose based on metadata needs.
ESI Protocol — set early to avoid disputes.

Discovery Deadlines Cheat Sheet

Task	Deadline
Serve written discovery	65 days before the initial trial date if served by mail in California
Respond to written discovery	30 days (plus 5 for mail, or 2 court days for email until January 1, 2027)
Bring motion to compel further	45 days after service of verified response
Discovery cut‑off	30 days before the initial trial date
Motion cut‑off	Heard by 15 days before the initial trial date

Practical Tips for Efficient Discovery

Prioritize high‑impact requests tied to key claims.
Use RFAs to authenticate documents and save trial time.
Stagger discovery to avoid overwhelming the other side (and yourself).
Track deadlines with a shared calendar or case‑management software.
Review responses promptly to preserve motion‑to‑compel deadlines.
