# Federal discovery practice: source and coverage ledger

This reference is a research aid for the `document-discovery` skill, not a substitute for the governing rule text, a case-specific order, or counsel's judgment. It was assembled for a U.S. federal civil-practice baseline as of 2026-09-03. Confirm the text and effective date at the time of use: the Judiciary identifies proposed Civil Rules 26 and 45 with a projected December 1, 2027 effective date, so proposed amendments are not current law.

## Rule ledger and operational implications

### Rule 26(b): scope, limits, work product, and privilege claims

Rule 26(b)(1) permits discovery of nonprivileged matter relevant to a claim or defense and proportional to the needs of the case. The proportionality factors are the importance of the issues, the amount in controversy, the parties' relative access to information, the parties' resources, the importance of discovery in resolving the issues, and whether burden or expense outweighs likely benefit. Discoverability is not limited to material that would itself be admissible at trial.

Rule 26(b)(2) directs limits where the request is unreasonably cumulative or duplicative, can be obtained from a more convenient or less burdensome source, gives the requesting party ample opportunity, or falls outside the scope. Electronically stored information that is inaccessible because of undue burden or cost may be excluded, but a court may order discovery for good cause subject to Rule 26(b)(1) limits. A drafting note should connect the proposed boundary to the facts rather than recite proportionality as a conclusion.

Rule 26(b)(3) protects trial-preparation materials prepared by or for a party or representative. Ordinary materials require substantial need and inability to obtain the substantial equivalent without undue hardship; an attorney's mental impressions, conclusions, opinions, or legal theories receive heightened protection. Hickman is foundational, but the current rule and circuit applications govern the specific item.

Rule 26(b)(5)(A) requires a party withholding otherwise discoverable information on privilege or work-product grounds to expressly make the claim and describe the nature of the documents, communications, or tangible things in a way that permits assessment without revealing the protected substance. The rule supplies a functional minimum, not a nationwide mandatory column list. Local rules and orders often specify fields, timing, categorical treatment, sampling, or exceptions.

Rule 26(b)(5)(B) provides the response to a notice that information was inadvertently produced: promptly return, sequester, or destroy the specified information and copies; take reasonable steps to retrieve it if disclosed before notice; and, if disputed, present it to the court under seal. The producing party must preserve the information pending resolution. The skill can queue these steps for counsel but cannot take them or contact anyone.

### Rule 26(c): protective orders

On good cause, the court may issue an order protecting a party or person from annoyance, embarrassment, oppression, or undue burden or expense. Possible relief includes forbidding or limiting discovery, specifying terms, changing time/place/method, limiting scope, or allocating expenses. A motion requires the conferral certification specified by Rule 26(c)(1), subject to local and judge-specific requirements. A work product should identify the requested protection and evidentiary basis; it should not assume confidentiality alone establishes good cause.

### Rule 26(f): planning and conference

The parties must confer as soon as practicable, and at least 21 days before the Rule 16 scheduling conference or scheduling order, unless the court orders otherwise. They discuss claims and defenses, initial disclosures, preservation, and a discovery plan. The written report is generally due within 14 days after the conference. The plan addresses timing, subjects, phasing, limitations, ESI preservation and production forms, privilege claims and log timing or method, and whether to seek a Rule 502 order. Local rules and orders can shorten deadlines, alter reporting, or require a particular form or additional ESI detail.

### Rule 26(g): reasonable inquiry and certification

An attorney or unrepresented party signing a discovery request, response, or objection certifies after reasonable inquiry that it is consistent with the rules and existing law or a nonfrivolous argument for change, is not interposed for an improper purpose, and is not unreasonable, unduly burdensome, or unduly expensive in light of the case needs. An unsigned paper can be stricken, and sanctions can follow without substantial justification. This is why the drafting record should preserve the scope rationale, burden information, and authority receipt instead of using boilerplate.

### Rule 33: interrogatories

Rule 33 generally limits a party to 25 interrogatories, including discrete subparts, unless otherwise stipulated or ordered. They may seek facts, the application of law to fact, and opinions or contentions; an objection is not valid merely because an answer would involve an opinion or application of law to fact. Answers and objections are written, separately and fully, under oath, with a 30-day default response period subject to the rule and case orders.

The grounds for an objection must be stated with specificity; an unstated ground is ordinarily waived unless the court excuses the failure for good cause. Rule 33(d) permits a records-based answer when the answer can be derived or ascertained from business records and the burden of deriving it is substantially the same for either party, but the responding party must identify the records with enough detail to locate them and provide a reasonable opportunity to examine, audit, or copy them. Local rules can sequence or limit interrogatories; SDNY/EDNY Rule 33.3 is an example, not a national pattern.

### Rule 34: requests for production and 2015 specificity changes

Rule 34 reaches documents, ESI, and tangible things within the responding person's possession, custody, or control, and permits entry onto land for inspection or related activity, within Rule 26(b). Each item or category must be described with reasonable particularity and may specify a reasonable time, place, or manner. The request may specify an ESI form. The default response period is 30 days, but early requests under Rule 26(d)(2), stipulations, orders, and local practice matter.

The response must state for each item or category whether inspection and related activities will be permitted or the grounds for objection. An objection must state whether responsive materials are being withheld. A partial objection must specify the part and permit inspection of the rest. Documents are produced as kept in the usual course of business or organized and labeled to correspond to the request categories under Rule 34(b)(2)(E)(i). If no ESI form was specified or the responding party objects to the requested form, the response must state the form it intends to use; ESI is produced in the form ordinarily maintained or another reasonably usable form under Rule 34(b)(2)(E)(ii). A party need not produce the same ESI in more than one form unless ordered.

The 2015 amendments sharpened response practice by requiring specific objection grounds and disclosure of withholding, clarifying partial objections, and permitting early delivery of Rule 34 requests under Rule 26(d)(2). The reasonable-particularity requirement for requests predated those amendments. The same amendment package removed the former “reasonably calculated to lead to admissible evidence” phrase from Rule 26(b)(1). The changes are not a license to refuse relevant discovery; they are reasons to draft bounded requests and explain the concrete response position.

### Rule 36: requests for admission

Each request must be separately stated and may concern facts, application of law to fact, or genuineness of documents. The 30-day default response period applies unless the parties or court set another time; failure to respond admits the matter. An answer must admit, deny, or explain why the matter cannot truthfully be admitted or denied after reasonable inquiry. A denial must fairly respond to the substance, and a qualified answer must specify the part admitted or denied.

An objection must state its grounds. A party may not object solely because the request presents a genuine issue for trial. An admission is conclusive in the action unless withdrawn or amended by court permission under the rule. Rule 37(c)(2) can shift reasonable expenses when a party fails to admit a matter later proven. Track service and response dates rather than assuming a missed date has already produced an irreversible result.

### Rule 37(a) and meet-and-confer

A motion to compel must include the certification that the movant conferred or attempted to confer in good faith to obtain the disclosure without court action. Rule 37(a)(2) assigns venue for motions involving a party and a nonparty deponent, while a documents-only nonparty subpoena ordinarily follows Rule 45's compliance-court path. An evasive or incomplete disclosure, answer, or response is treated as a failure. Expense shifting has specified exceptions, including substantially justified positions and circumstances making an award unjust. Local rules may require a personal conference, a letter, a pre-motion conference, quoted requests and responses, or a particular certification.

A useful memorialization is factual and request-specific: date, participants, medium, exact requests and responses discussed, each side's concrete proposal, burden/benefit information, agreed scope or date, unresolved issues, and next step. An email chain may be inadequate under some judge procedures; the skill flags this for verification rather than making contact.

### Rule 37(e): lost ESI

Rule 37(e) applies when ESI that should have been preserved in anticipation or conduct of litigation is lost because a party failed to take reasonable steps, and the information cannot be restored or replaced through additional discovery. Under Rule 37(e)(1), if another party is prejudiced, the court may order measures no greater than necessary to cure the prejudice. Under Rule 37(e)(2), a finding that the party acted with intent to deprive another party of the information permits a presumption or adverse-inference instruction and potentially dismissal or default.

The rule does not itself create a preservation duty, impose perfection, or make negligence alone sufficient for the severe measures in subdivision (e)(2). The Eleventh Circuit's bad-faith formulation is circuit-specific; other circuits' interpretations and the facts of the preservation record must be checked. Queue the preservation facts—notice, holds, systems, ordinary deletion, custodians, steps taken, loss, replaceability, prejudice, and intent evidence—for counsel rather than declaring spoliation.

### Rule 45: subpoena triage

Rule 45 supplies the subpoena's issuing-court framework and permits service nationwide, subject to the rule's contents, notice, fees, and geographic limits. Before serving a subpoena commanding production, ESI, tangible things, or premises inspection, the serving party must serve each party with notice and a copy as Rule 45(a)(4) provides. The issuing court is generally the court where the action is pending; compliance is usually within the rule's geographic limits and may involve a different compliance court. A party must take reasonable steps to avoid imposing undue burden or expense on a person subject to the subpoena.

For a subpoena commanding production, inspection, copying, testing, or sampling, Rule 45(d)(2)(B) permits written objections before the earlier of the compliance date or 14 days after service. That written-objection mechanism does not by itself excuse commanded testimony; testimony, protection, or quashing follows the applicable Rule 45(c) and (d)(3) path. The compliance court must quash or modify a subpoena that allows inadequate time, exceeds geographic limits, requires certain protected disclosure, or subjects a person to undue burden, with the rule's specified alternatives. It may protect a person from significant expense. Rule 45's ESI provisions address ordinary-course or organized production, specified or stated forms, and inaccessible ESI for undue burden or cost with possible good-cause relief.

Rule 45 incorporates a privilege-log and clawback track through Rule 26(b)(5). Transfer to the issuing court under Rule 45(f) requires consent or exceptional circumstances; contempt authority follows the rule's issuing/compliance allocation and any transfer. These issues are triage questions, not permission for the skill to serve, object, comply, or move.

### Privilege, Rule 502, and logs

FRE 501 directs which privilege law applies in civil cases where state law supplies the rule of decision. FRE 502(a) can produce subject-matter waiver after an intentional disclosure in a federal proceeding when fairness requires it. FRE 502(b) addresses inadvertent disclosure when it was inadvertent, reasonable prevention measures were used, and prompt reasonable steps were taken to rectify. FRE 502(c) addresses state proceedings; Rule 502(d) permits a federal court order that disclosure does not waive privilege in that or any other federal or state proceeding; and Rule 502(e) makes a party agreement binding on the parties unless incorporated into a court order.

Rule 502 is a waiver framework, not the source of attorney-client privilege or work-product protection. Upjohn and Hickman are foundational Supreme Court authorities, but circuit law controls privilege elements, litigation-purpose questions, common-interest or confidentiality issues, and waiver details. A log must allow assessment without disclosing the protected substance. The safest national pattern is an itemized, date/author/recipient/type/subject/privilege-basis log with relationships and redaction or partial-production information, but the operative local rule or order controls.

## Jurisdictional variation and non-generic propositions

These propositions require local verification before being handed to a lawyer as an instruction: the number of interrogatories; sequencing of contention interrogatories; whether a live or personal meet-and-confer is required; the acceptable length and format of a discovery letter or motion; pre-motion court conferences; privilege-log fields, categorical treatment, or timing; subpoena objection and compliance mechanics; ESI search-term or collection disclosures; whether a judge adopts Sedona guidance; and how a circuit defines intent, prejudice, reasonable steps, control, or waiver.

The following are safe as national starting points only, with their caveats: Rule 26(b)(1) proportionality applies to discovery scope; Rule 26(g) requires reasonable inquiry and bars improper or unreasonable discovery; Rule 34 requires specificity and disclosure of withholding; Rule 37(a) requires good-faith conferral certification; Rule 37(e) sets the lost-ESI threshold and separates prejudice from intent-to-deprive measures; and Rule 45 requires subpoena-specific geographic, burden, notice, service, and court analysis.

Do not state as generic legal advice that an objection is automatically waived, that every “subject to” response is invalid, that privilege logs always require one universal set of fields, that a Rule 502(d) order is automatic, that a Rule 45 compliance court is always the issuing court, that negligence automatically supports an adverse inference, or that Sedona materials bind the court. Identify the authority and factual reason for each conclusion.

## Coverage and contradiction register

The national rules are internally complementary, but default timing, numerical limits, conference methods, log formats, discovery sequencing, and motion routes may be changed by a stipulation, scheduling order, local rule, or judge practice. The 2015 explanatory materials describe the intended direction of the amendments but cannot resolve later circuit splits or a particular judge's application. The Fifth Circuit BDO decision, Eleventh Circuit Rule 37(e) decision, SDNY/EDNY rules, N.D. Cal. standing-order example, and S.D. Fla. materials are deliberately retained as variation examples, not universal templates.

The principal research gaps are case-specific: operative district and judge; applicable circuit law; live scheduling and discovery orders; whether state law supplies a privilege rule; exact service and response dates; what ESI was preserved or lost; the parties' relative access and resources; and the subpoena's service, compliance, and witness location. If any is missing, the output must carry an open issue and a current/local-authority check rather than a definitive legal answer.

## Suggested receipt record

For a completed work package, record one row per material proposition in this shape: `source_id`; authority tier; title/publisher; effective or decision date; direct URL; retrieval date; precise locator; paraphrased proposition; how it supports the request, response, triage, or queue; and limits. Add an `authority_check_status` of `confirmed`, `local_check_pending`, `currentness_pending`, `source_unavailable`, or `not_applicable`. Keep the served instrument and the receipt separately so later changes can be detected.
