California Bar Discovery

Last updated: May 2, 2026

Discovery questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

Under FRCP 26(b)(1), parties may obtain discovery of any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case, considering the importance of the issues, the amount in controversy, the parties' relative access to information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense outweighs the likely benefit. Information need not be admissible to be discoverable. California's Civil Discovery Act (CCP §§ 2016.010–2036.050) reaches any matter, not privileged, that is relevant to the subject matter and either admissible or reasonably calculated to lead to admissible evidence — a broader 'subject matter' scope without the federal proportionality limitation, though California courts police burden through protective orders (CCP § 2017.020) and a separate good-cause showing is required for discovery of a defendant's financial condition in punitive-damages cases (Civ. Code § 3295(c)). Privileges (attorney-client, marital, etc.) and the qualified work-product doctrine (FRCP 26(b)(3); CCP § 2018.030 — absolute protection in California for an attorney's impressions, conclusions, opinions, or legal research) shield otherwise relevant material.

Elements breakdown

Scope of Discovery — Federal (FRCP 26(b)(1))

A party may discover any nonprivileged matter relevant to a claim or defense and proportional to the needs of the case.

  • Nonprivileged matter
  • Relevant to any party's claim or defense
  • Proportional to needs of the case
  • Need not be admissible at trial

Scope of Discovery — California (CCP § 2017.010)

A party may obtain discovery of any matter, not privileged, relevant to the subject matter and either itself admissible or reasonably calculated to lead to admissible evidence.

  • Not privileged
  • Relevant to subject matter of the action
  • Admissible or reasonably calculated to lead to admissible evidence
  • Subject to protective orders for undue burden (CCP § 2017.020)

Mandatory Initial Disclosures (FRCP 26(a)(1))

Without awaiting a request, parties must disclose specified categories of information early in the case.

  • Names and contact info of likely witnesses with discoverable information
  • Copies or descriptions of documents/ESI/tangible things supporting claims or defenses
  • Computation of each category of damages claimed
  • Insurance agreements that may satisfy a judgment
  • Made within 14 days of the Rule 26(f) conference (no California analog — CA has no mandatory initial disclosures)

Depositions (FRCP 30; CCP §§ 2025.010 et seq.)

Oral examination of a party or non-party witness under oath, on the record.

  • Notice to all parties (subpoena required for non-parties)
  • Federal default: 10 depositions per side, 1 day of 7 hours each (FRCP 30(a)(2)(A), 30(d)(1))
  • California: no numerical limit; natural-person deposition capped at 7 hours total (CCP § 2025.290), with exceptions
  • Objections must be stated concisely and non-argumentatively; instructions not to answer only to preserve privilege/limit/court order (FRCP 30(c)(2); CCP § 2025.460)

Interrogatories (FRCP 33; CCP §§ 2030.010 et seq.)

Written questions to a party that must be answered in writing under oath.

  • Federal: limit of 25 interrogatories including discrete subparts, party-to-party only (FRCP 33(a)(1))
  • California: 35 specially prepared interrogatories per party (CCP § 2030.030(a)(1)); more allowed via declaration of necessity (CCP § 2030.040)
  • California also permits unlimited Judicial Council form interrogatories (CCP § 2030.030(a)(2))
  • Each interrogatory must be full and complete in itself; no preface or instructions (CCP § 2030.060(d))
  • Answers due in 30 days (federal) / 30 days plus 5 if served by mail (California, CCP § 2030.260)

Requests for Production (FRCP 34; CCP §§ 2031.010 et seq.)

Written requests to inspect, copy, or test documents, ESI, or tangible things in another party's possession, custody, or control.

  • Reasonable particularity in describing items
  • Documents/ESI in responding party's possession, custody, or control
  • Response identifies items, objections, and any items withheld
  • Federal: produce as kept in usual course or organize/label by request (FRCP 34(b)(2)(E))
  • California: 30-day response (CCP § 2031.260)

Requests for Admission (FRCP 36; CCP §§ 2033.010 et seq.)

Written requests asking another party to admit truth of facts, application of law to fact, or genuineness of documents.

  • Federal: no numerical limit (FRCP 36)
  • California: 35 RFAs per party except unlimited as to genuineness of documents (CCP § 2033.030)
  • Matters admitted are conclusively established for that action (FRCP 36(b); CCP § 2033.410)
  • Failure to admit triggers cost-shifting if requesting party later proves the matter (FRCP 37(c)(2); CCP § 2033.420)

Physical or Mental Examinations (FRCP 35; CCP §§ 2032.010 et seq.)

Examination of a party whose physical or mental condition is in controversy, ordered for good cause.

  • Physical or mental condition in controversy
  • Good cause shown
  • Federal: requires court order (FRCP 35(a))
  • California: defense physical exam of personal-injury plaintiff allowed by demand without court order (CCP § 2032.220); mental exams and exams of others require leave of court

Expert Witness Discovery

Discovery of testifying and consulting experts is sharply different in federal and California practice.

  • Federal: automatic Rule 26(a)(2) reports for retained experts; consulting experts protected absent exceptional circumstances (FRCP 26(b)(4)(D))
  • California: simultaneous mutual exchange of expert witness lists by demand under CCP § 2034.210; expert depositions allowed under § 2034.410
  • Failure to designate in California timely waives the right to call that expert (§ 2034.300)

Work-Product Doctrine

Materials prepared in anticipation of litigation by or for a party or its representative receive qualified or absolute protection.

  • Federal: qualified protection — discoverable on showing of substantial need and inability to obtain equivalent without undue hardship (FRCP 26(b)(3)(A))
  • Federal: opinion work product (mental impressions, conclusions, opinions, legal theories) gets near-absolute protection
  • California: attorney's impressions, conclusions, opinions, or legal research/theories are absolutely protected (CCP § 2018.030(a))
  • California: other work product receives qualified protection (CCP § 2018.030(b))

Discovery Cutoffs (California)

California imposes specific cutoffs tied to trial date, with no direct federal counterpart.

  • Non-expert discovery cutoff: 30 days before initial trial date (CCP § 2024.020)
  • Expert discovery cutoff: 15 days before initial trial date
  • Cutoff for hearing motions to compel: 15 days before trial
  • Continuances do not reopen discovery absent court order (CCP § 2024.020(b))

Meet-and-Confer & Motions to Compel (FRCP 37; CCP §§ 2023, 2030.300, 2031.310, 2025.480)

Before moving to compel, the moving party must in good faith attempt informal resolution.

  • Good-faith meet-and-confer required
  • Motion to compel further responses (CA): 45 days from verified response or supplemental verification (CCP § 2030.300(c))
  • Federal: no fixed deadline but governed by scheduling order
  • Court may order responses, impose monetary sanctions, and escalate to issue/evidence/terminating sanctions

Sanctions (FRCP 37; CCP § 2023.030)

Courts may impose graduated sanctions for discovery misuse, from monetary to case-dispositive.

  • Monetary sanctions (reasonable expenses including attorney's fees)
  • Issue sanctions (designated facts taken as established)
  • Evidence sanctions (prohibiting introduction of designated matters)
  • Terminating sanctions (striking pleadings, dismissal, default)
  • Contempt

Common patterns and traps

The Federal-vs-California Switch

The fact pattern is set in California state court but the answer choices invite you to apply federal numerical limits, federal proportionality language, or federal expert-disclosure procedures. The trap works because federal rules are taught first and feel more familiar, especially the 25-interrogatory cap and the FRCP 26(a)(2) expert report. Always pin down the forum in the first sentence of your analysis.

A choice that says 'No, because the party served more than 25 interrogatories' when the action is in California superior court and California's 35-special-plus-unlimited-form regime governs.

The Work-Product Conflation

A choice treats all work product as qualified-protection-only, allowing discovery on substantial need + undue hardship, when the action sits in California and the material at issue is opinion work product. California Code of Civil Procedure § 2018.030(a) gives an attorney's impressions, conclusions, opinions, and legal research absolute protection — there is no substantial-need override. Federal opinion work product gets near-absolute protection but courts have allowed limited piercing in extreme cases.

A choice that says 'Yes, the notes are discoverable because the opposing party can show substantial need and inability to obtain the substantial equivalent' applied to a California attorney's strategy memo.

The Cutoff-Continuance Trap

A scheduling order or stipulated continuance pushes the trial date back, and the answer choice assumes discovery automatically reopens. Under CCP § 2024.020(b), a continuance does not reopen discovery absent a court order on motion. Candidates miss this because federal scheduling-order practice often automatically extends discovery deadlines.

A choice that says 'Yes, the deposition was timely because the trial was continued, automatically extending the discovery cutoff' in a California fact pattern.

The Demand-vs-Order Trap for Physical Exams

Federal practice always requires a court order for a Rule 35 examination. California allows a defense physical exam of a personal-injury plaintiff by mere demand, without court order, under CCP § 2032.220. Mental exams and exams of non-PI plaintiffs still require leave of court. The trap punishes candidates who reflexively apply the federal rule to a state-court PI case.

A choice that says 'No, because the defendant did not obtain a court order before noticing the physical examination' in a California PI action.

The Meet-and-Confer Skip

A party files a motion to compel without first attempting informal resolution, and a tempting answer choice ignores this prerequisite. Both federal (FRCP 37(a)(1)) and California practice (CCP §§ 2030.300(b), 2031.310(b), 2025.450(b)) require a good-faith meet-and-confer attempt before discovery motions, and California courts routinely deny motions for failure to comply.

A choice that says 'Yes, the court will compel further responses' without addressing whether the moving party met and conferred.

How it works

Picture this. Reyes sues Liu Manufacturing in California state court alleging a defective forklift caused her back injury. Reyes serves 40 specially prepared interrogatories without a declaration of necessity — the first trap. Liu can object to interrogatories 36–40 because California caps specially prepared interrogatories at 35 unless the propounding party serves a CCP § 2030.050 declaration justifying more. Liu in turn demands a defense medical exam of Reyes's back; in California, that's allowed by demand without a court order because Reyes's physical condition is in controversy in a personal-injury action (CCP § 2032.220) — but if Liu also wanted a mental exam, that would require leave of court. Reyes's lawyer's notes summarizing his theory of the case are absolutely protected under CCP § 2018.030(a) — opinion work product gets stronger protection in California than under federal law. When trial is set for October 1, non-expert discovery closes August 31 (30 days before trial), expert discovery closes September 16 (15 days before), and Reyes can't unilaterally extend by stipulating to a continuance. The candidate trap is to default to FRCP scope and limits when a California state-court fact pattern controls — or vice versa.

Worked examples

Worked Example 1

How should the court rule on Patel's motion to compel?

  • A Grant the motion, because California permits up to 50 specially prepared interrogatories per party.
  • B Grant the motion, because Reyes Manufacturing failed to seek a protective order before objecting.
  • C Deny the motion, because Patel did not serve a declaration of necessity supporting more than 35 specially prepared interrogatories. ✓ Correct
  • D Deny the motion, because California state courts apply the federal 25-interrogatory cap under FRCP 33.

Why C is correct: Under CCP § 2030.030(a)(1), a party may serve 35 specially prepared interrogatories on another party. To exceed that number, the propounding party must serve a declaration of necessity meeting the requirements of CCP § 2030.040 — explaining the complexity, quantity of issues, or other circumstances justifying additional interrogatories. Without that declaration, the responding party may object to interrogatories beyond 35 (CCP § 2030.030(c)), and that is exactly what Reyes Manufacturing did. The objection is well-taken, and Patel's motion to compel must be denied.

Why each wrong choice fails:

  • A: California's special-interrogatory cap is 35, not 50. There is no 50-interrogatory baseline anywhere in the Civil Discovery Act; the propounding party must use the declaration-of-necessity mechanism under CCP § 2030.040 to exceed 35. (The Federal-vs-California Switch)
  • B: Objecting to interrogatories that exceed the statutory limit is the responding party's correct procedural move under CCP § 2030.030(c) — the responding party need not affirmatively seek a protective order. Forcing a protective-order requirement onto routine numerical objections inverts the burden the statute places on the propounding party. (The Meet-and-Confer Skip)
  • D: FRCP 33's 25-interrogatory cap governs federal court only. A California superior court action is governed by the California Civil Discovery Act, which sets the cap at 35 specially prepared interrogatories with unlimited form interrogatories under CCP § 2030.030(a)(2). (The Federal-vs-California Switch)
Worked Example 2

How should the federal court rule on Liu's motion to compel an answer to the second question?

  • A Grant the motion, because the witness's personal beliefs are not communications with counsel and are not work product. ✓ Correct
  • B Deny the motion, because the witness's mental impressions are absolutely protected opinion work product.
  • C Grant the motion, because work product never protects information held by the client rather than by counsel.
  • D Deny the motion, because the work-product doctrine extends to all impressions formed in anticipation of litigation.

Why A is correct: Federal work product under FRCP 26(b)(3)(A) protects 'documents and tangible things' prepared in anticipation of litigation by or for a party or its representative — it does not shield a deponent's personal beliefs or mental state from oral examination. Attorney-client privilege protects the communications themselves (which the question expressly carved out), but the witness's own beliefs about the merits are not communications and are not the work product of counsel. Federal Rule 30(c)(2) permits an instruction not to answer only to preserve a privilege, enforce a court-ordered limitation, or present a Rule 30(d)(3) motion — none applies. The court should compel an answer.

Why each wrong choice fails:

  • B: The witness's personal beliefs are not 'opinion work product' under FRCP 26(b)(3)(B), which protects the mental impressions, conclusions, opinions, and legal theories of an attorney or other representative — not the personal opinions of a lay deponent. Conflating client beliefs with attorney mental impressions stretches work product past its doctrinal limits. (The Work-Product Conflation)
  • C: Right outcome, wrong reason. Work product can extend to materials prepared by a party or its representative — not 'never' to client-side material — but the doctrine still requires that the material be a 'document or tangible thing' prepared in anticipation of litigation, which a deponent's oral answer about personal beliefs is not.
  • D: Work product does not extend to 'all impressions formed in anticipation of litigation.' The federal doctrine is limited to documents and tangible things prepared by or for a party or its representative; opinion work product expansion applies to attorney mental impressions, not to a fact witness's personal views. (The Work-Product Conflation)
Worked Example 3

How should the court rule on Norwood's motion to compel the physical examination?

  • A Deny the motion, because under federal practice a party must obtain a court order before any Rule 35 examination.
  • B Deny the motion, because the discovery cutoff under CCP § 2024.020 expired on August 31.
  • C Grant the motion, because in a personal-injury action a defendant may demand a physical examination of the plaintiff without a court order under CCP § 2032.220. ✓ Correct
  • D Grant the motion, but only after Norwood obtains a court order showing good cause.

Why C is correct: Under California Code of Civil Procedure § 2032.220, in any case in which the plaintiff places her physical condition in controversy, the defendant may demand one physical examination of the plaintiff without leave of court, provided the exam is conducted by a licensed physician within 75 miles of the plaintiff's residence and uses no diagnostic test that is painful, protracted, or intrusive. Garcia is a personal-injury plaintiff whose physical condition is plainly at issue, and the demand satisfies the statutory parameters. The exam is scheduled for September 10, which is before the September 16 expert-discovery cutoff and before any non-expert deadline objection would mature against this exam, so the cutoff does not bar it. Norwood's motion to compel should be granted.

Why each wrong choice fails:

  • A: This applies the federal Rule 35 court-order requirement to a California state-court action. California's Civil Discovery Act expressly permits a defense physical exam of a personal-injury plaintiff by mere demand under CCP § 2032.220 — no court order is needed unless the exam involves diagnostic tests outside the statutory scope or seeks a mental exam. (The Demand-vs-Order Trap for Physical Exams)
  • B: The non-expert discovery cutoff under CCP § 2024.020(a) is 30 days before the initial trial date — September 1, not August 31, given an October 1 trial date — and the exam is timely-noticed in any event because the demand was served on August 20 with the exam scheduled before September 16 (the expert-discovery cutoff is irrelevant here, but no cutoff has expired). The choice misapplies the cutoff calendar. (The Cutoff-Continuance Trap)
  • D: Right outcome, wrong reason. The court will grant the motion, but Norwood does not need a court order or a good-cause showing for a routine personal-injury defense physical exam under CCP § 2032.220. A good-cause-plus-order requirement applies to mental exams (§ 2032.310) and to exams beyond the statutory parameters — not to this demand. (The Demand-vs-Order Trap for Physical Exams)

Memory aid

Discovery devices = 'DIRPM': Depositions, Interrogatories, Requests for production, Requests for admission, Physical/Mental exams. California numerical caps = 'Three-Five for All Five (almost)': 35 specially prepared interrogatories, 35 RFAs (except unlimited for document genuineness), 30-day response window. Cutoffs = '30/15/15': non-expert 30 days before trial, expert 15 days before, motion hearings 15 days before.

Key distinction

The single most important distinction is federal proportionality + numerical caps (FRCP 26(b)(1), 30, 33, 36) versus California's broader 'subject matter' scope with category-specific numerical caps (CCP §§ 2017.010, 2030.030, 2033.030) — and within each, the divergent treatment of work product (qualified federal vs. absolute California for opinion work product). Always identify the forum first; the forum dictates which scope, which device limits, and which timetable governs.

Summary

Discovery questions are forum-sensitive: identify whether the FRCP or California's Civil Discovery Act governs, then apply the correct scope, the correct device-specific limits, the correct privilege/work-product protection, and the correct cutoff/sanctions framework.

Frequently asked questions

What is discovery on the California Bar?

Under FRCP 26(b)(1), parties may obtain discovery of any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case, considering the importance of the issues, the amount in controversy, the parties' relative access to information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense outweighs the likely benefit. Information need not be admissible to be discoverable. California's Civil Discovery Act (CCP §§ 2016.010–2036.050) reaches any matter, not privileged, that is relevant to the subject matter and either admissible or reasonably calculated to lead to admissible evidence — a broader 'subject matter' scope without the federal proportionality limitation, though California courts police burden through protective orders (CCP § 2017.020) and a separate good-cause showing is required for discovery of a defendant's financial condition in punitive-damages cases (Civ. Code § 3295(c)). Privileges (attorney-client, marital, etc.) and the qualified work-product doctrine (FRCP 26(b)(3); CCP § 2018.030 — absolute protection in California for an attorney's impressions, conclusions, opinions, or legal research) shield otherwise relevant material.
