Litigation

This checklist walks a civil case through discovery from the preservation duty that begins before filing to the sanctions motion that ends a dispute about production. It is organized by stage, with a box for every action and a note explaining why it matters. It covers the litigation hold, the Rule 26(f) conference and the terms worth negotiating there, initial disclosures, the drafting and service of each written device, deposition and subpoena mechanics, expert exchange, and the enforcement ladder. It flags the deadlines that operate automatically and the failures that produce automatic exclusion. Use it as a running worksheet rather than a one-time read.

Serving, Answering, and Enforcing Discovery: A Practical Checklist

Litigation > Discovery and Evidence | Published 26 November 2025 - Updated 2 July 2026 | UpLaw - uplaw.us

This checklist assumes federal practice under the Federal Rules of Civil Procedure. ⚠ State rules differ on interrogatory limits, deposition limits, initial disclosures, expert exchange, and spoliation standards. Confirm each item against your own jurisdiction's rule before relying on it.

Work through the stages in order. Boxes that carry a ⚠ operate automatically — miss them and no motion is required for the harm to occur.

Stage 1 — Before anything is filed

☐ Identify the trigger date for preservation. The duty attaches when litigation is reasonably anticipated — an injury with a report, a demand letter, an internal complaint, a regulatory inquiry, a threat to sue. Write down the date and the reason.

☐ Issue the litigation hold in writing. Identify the matter, the subject, the date range, the custodians, and the categories.

☐ List every system, not just email. Chat platforms, text messages on personal devices, shared drives, ticketing and case-management systems, databases, voicemail, calendars, photographs, video, telematics, badge and access logs, and any backup media within scope.

☐ Suspend automatic deletion. Email retention policies, ephemeral chat settings, surveillance overwrite cycles, and — the one everyone forgets — device reimaging when an employee departs.

☐ Collect acknowledgments and calendar reminders. A hold issued once and never followed up is the classic losing fact pattern in a spoliation motion.

☐ Send a preservation letter to the other side if you are the claimant. Name the categories with specificity. In injury and product cases, send it within days: see preserving evidence and pursuing a product liability claim and documenting and presenting a premises liability claim.

☐ Preserve physical evidence separately. Rule 37(e) covers only electronically stored information; a destroyed vehicle or a repaired staircase is governed by inherent authority and state law.

☐ Confirm the limitations deadline before you spend a month on preservation. See calculating and preserving a limitations deadline.

Stage 2 — Pleadings and the shape of discovery

☐ Read your own complaint as a discovery document. Relevance under Rule 26(b)(1) is measured against pleaded claims and defenses. What is not pleaded is hard to discover.

☐ Check pleading sufficiency. Rule 8 for the general standard; Rule 9 for fraud and mistake, which require particularity.

☐ Calendar the deadline to amend. Rule 15 is liberal early and unforgiving after the Rule 16 cutoff.

☐ Decide whether a threshold issue should be phased. Arbitrability, limitations, standing, or class certification can each be litigated first at a fraction of the cost.

Stage 3 — The Rule 26(f) conference and scheduling order

☐ Hold the conference at least 21 days before the scheduling conference or order.

☐ Negotiate an ESI protocol. Custodians, date range, data sources, search methodology, de-duplication, form of production, metadata fields, and a dispute process.

☐ Ask for a Rule 502(d) order. One paragraph; it prevents privilege waiver from an inadvertent production in any federal or state proceeding. There is no reason to skip it.

☐ Agree not to log post-complaint attorney-client communications. Nearly universal, and it removes thousands of privilege-log entries.

☐ Agree on categorical privilege logging if the volume warrants it. This must be agreed in advance; it is very hard to obtain retroactively.

☐ Propose deposition and interrogatory limits deliberately rather than accepting defaults you will later need to modify.

☐ Calendar every date in the scheduling order the day it issues. Fact discovery close, expert disclosures, rebuttal experts, expert discovery close, dispositive motions.

☐ ⚠ Note that modification requires good cause and diligence under Rule 16(b)(4). "We ran out of time" is not good cause.

Stage 4 — Initial disclosures

☐ Serve within 14 days of the Rule 26(f) conference.

☐ Witnesses — name, address, telephone for each individual likely to have discoverable information you may use to support your claims or defenses.

☐ Documents — copies or a description by category and location of documents you may use.

☐ Damages computation — by category, with supporting documents available. A conclusory number invites a motion and, later, exclusion.

☐ Insurance agreements — any policy under which an insurer may be liable to satisfy a judgment. This is disclosed without a request.

☐ ⚠ Understand Rule 37(c)(1): information or a witness not disclosed may not be used at a hearing, motion, or trial unless the failure was substantially justified or harmless. No motion is needed for this to bite.

☐ Diary supplementation. Rule 26(e) imposes a continuing duty. Set a recurring reminder to review disclosures every sixty days.

Stage 5 — Written discovery you serve

Interrogatories

☐ Count them, including discrete subparts. Twenty-five is the federal limit.

☐ Use them for identification, not narrative. People, entities, systems, Bates ranges, computations.

☐ Ask who the person most knowledgeable is for each system. That answer becomes your deposition list.

☐ Save contention interrogatories for the end of fact discovery.

Requests for production

☐ Define terms once at the top and use them consistently.

☐ Bound every request by date.

☐ Prefer "documents sufficient to show." It asks for the answer, not the haystack, and is difficult to resist.

☐ Specify the form of production — native with metadata for spreadsheets, databases, and anything where authorship or timing matters.

☐ Request the document retention policy and the organizational chart in the first set. They tell you what exists and who holds it.

☐ Request the litigation hold's issuance date and custodian list if spoliation is a live concern. The hold's content is usually privileged; its existence and scope often are not.

Requests for admission

☐ Use them to authenticate documents. Authenticity fights at trial are avoidable and expensive.

☐ Use them to fix dates, employment, ownership, and contract execution.

☐ Keep each request to a single fact. Compound requests draw qualified answers that admit nothing.

Stage 6 — Written discovery you answer

☐ Calendar the 30-day deadline the day the requests arrive.

☐ ⚠ Requests for admission are deemed admitted if you do not respond in 30 days. This is automatic. If it has already happened, move immediately under Rule 36(b) to withdraw or amend.

☐ Object with specificity or not at all. General objections incorporated by reference are disregarded and increasingly sanctioned.

☐ State whether documents are being withheld. Rule 34(b)(2) requires it, and it is the single most useful sentence in a response.

☐ Quantify any burden objection. Custodians, gigabytes, review hours, dollars. An adjective is not an objection.

☐ Do not withhold merely because material is confidential. Confidentiality is not privilege; move for a protective order under Rule 26(c).

☐ Verify interrogatory answers under oath by the party, not counsel.

☐ If you cannot answer at all, move for a protective order. Rule 37(d) sanctions a complete failure to respond even where objections might have been valid.

☐ Search personal devices and accounts within your control. Personal ownership is not a shield.

☐ Log withheld privileged material. Date, author, all recipients, type, neutral subject, privilege asserted.

Stage 7 — Depositions

Noticing and scheduling

☐ Confirm you have the documents first. A deposition taken before production is an interview; taken after, it is evidence.

☐ Count against the presumptive limits — ten depositions per side, seven hours each under Rule 30.

☐ Serve reasonable written notice stating time, place, the deponent's name, and the method of recording.

☐ Subpoena non-parties under Rule 45 — a notice alone does not compel a stranger to appear.

☐ Respect the 100-mile rule for where a non-party may be required to appear.

☐ Decide on video. Video changes witness behavior and changes how a jury receives testimony that is read at trial.

Preparing your own witness

☐ Explain the three rules: answer only the question asked, say "I don't know" when you don't, and never guess.

☐ Review the key documents with the witness — not a script, but the exhibits they will certainly see.

☐ Practice the pause. A witness who waits two seconds before answering gives counsel time to object and gives themselves time to think.

☐ Warn about the reptile questions — broad safety-rule propositions that seem harmless and become the plaintiff's closing argument.

☐ Explain that "I don't recall" is an answer and "I assume" is not.

Preparing a Rule 30(b)(6) designee

☐ ⚠ Understand that the designee's testimony binds the organization, whether or not they have personal knowledge.

☐ Confer in good faith about the topics. The rule requires it, and narrowing topics is far easier before the notice is final.

☐ Object to overbroad topics in writing and promptly — not for the first time at the deposition.

☐ Gather documents and interview the people who know, then prepare the designee on the collected knowledge of the entity.

☐ Designate more than one person if the topics require it. There is no rule against it, and pretending one person knows everything is how organizations lose.

Taking a deposition

☐ Start with the background and the biography. It settles the witness and builds the foundation you will need later.

☐ Use documents as the spine. Mark the exhibit, establish authorship and receipt, then ask about the content.

☐ Ask the closing questions: is there anything else you relied on, is there anyone else who would know, is there any document you expected to see and did not.

☐ State objections concisely and without coaching. Rule 30(c)(2) allows "objection, form"; a speaking objection is sanctionable.

☐ Instruct not to answer only to preserve a privilege, enforce a court-ordered limit, or present a Rule 30(d)(3) motion.

☐ Note the errata rules. Review-and-sign rights must be requested before the deposition ends.

Stage 8 — Third-party discovery

☐ Serve notice on all parties before serving a documents-only subpoena. This is a prerequisite, not a courtesy.

☐ Take reasonable steps to avoid undue burden. Rule 45(d)(1) imposes the duty on the issuing attorney personally and authorizes sanctions.

☐ Expect written objections within 14 days, which shift the burden to you to move to compel.

☐ Be prepared to protect the non-party from significant expense if you compel production.

☐ Route sensitive categories through the right overlay — medical records under the HIPAA privacy rules at 45 C.F.R. part 164, employment files under state law, financial records under banking rules. See obtaining, correcting, and protecting medical records.

☐ Consider whether a records custodian declaration will substitute for a deposition. It usually will, and it is far cheaper.

Stage 9 — Experts

☐ Calendar the disclosure dates from the scheduling order, and work backward six weeks.

☐ Decide retained versus non-retained. A treating physician disclosed as non-retained cannot offer causation opinions beyond treatment in many courts.

☐ Confirm the report contains everything Rule 26(a)(2)(B) requires — all opinions and bases, facts or data considered, exhibits, qualifications, publications for ten years, testimony for four years, and compensation.

☐ Assume the facts and data you gave the expert are discoverable, even though drafts and most communications are protected.

☐ Prepare for the admissibility fight. Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993), General Electric Co. v. Joiner, 522 U.S. 136 (1997), and Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999) govern.

☐ ⚠ A late expert disclosure is excluded under Rule 37(c)(1) with disturbing regularity. In a case requiring expert causation, that is the case.

Stage 10 — Privilege and protection

☐ Assert privilege expressly and describe the withheld material under Rule 26(b)(5)(A).

☐ Watch the business-versus-legal-purpose line for in-house counsel. A communication seeking business advice is not privileged because a lawyer was copied.

☐ Apply the Upjohn warning at the start of every internal investigation interview: counsel represents the company, not the individual.

☐ Separate ordinary from opinion work product. Hickman v. Taylor, 329 U.S. 495 (1947), and Rule 26(b)(3) protect mental impressions nearly absolutely.

☐ Get the Rule 502(d) order entered — see Stage 3. Federal Rule of Evidence 502 supplies the framework.

☐ Follow the clawback mechanics in Rule 26(b)(5)(B): notify, and the receiver must return, sequester, or destroy and may submit the issue under seal.

☐ Negotiate a two-tier protective order — Confidential and Attorneys' Eyes Only — where competitors are involved. Seattle Times Co. v. Rhinehart, 467 U.S. 20 (1984), confirms such orders are constitutional.

☐ ⚠ Do not assume a protective order seals the court file. Sealing requires a separate showing against the public right of access.

Stage 11 — When the other side will not produce

☐ Write a request-by-request deficiency letter. Quote the request, describe what was produced, state what is missing, and set a date.

☐ Confer live. Rule 37(a)(1) requires a certification, and many districts require a telephone or in-person conference.

☐ Concede your weak requests. A requester who drops three marginal items gets the two important ones weeks sooner.

☐ Move to compel under Rule 37(a), attaching the requests, responses, and correspondence.

☐ Ask for fees. Rule 37(a)(5)(A) makes an expense award mandatory when the motion is granted or the material is produced after filing, absent substantial justification.

☐ Escalate for violation of an order under Rule 37(b): facts deemed established, claims or defenses barred, pleadings struck, dismissal, default, contempt.

☐ Consider the non-Rule 37 tools — 28 U.S.C. § 1927 for vexatious multiplication of proceedings, and inherent authority under Chambers v. NASCO, Inc., 501 U.S. 32 (1991), limited to compensatory amounts by Goodyear Tire & Rubber Co. v. Haeger, 581 U.S. 101 (2017).

☐ Remember Rule 26(g). Every disclosure, request, response, and objection carries a certification, and violation carries mandatory sanctions.

☐ Do not expect an immediate appeal. Mohawk Industries, Inc. v. Carpenter, 558 U.S. 100 (2009), forecloses collateral-order review of privilege rulings.

Stage 12 — Spoliation

☐ Establish the four threshold facts: the material was ESI, there was a duty to preserve, it was lost because reasonable steps were not taken, and it cannot be restored or replaced.

☐ Prove prejudice concretely. What would the missing material have shown, and what substitute exists?

☐ Separate the intent question. Under Rule 37(e)(2), only intent to deprive supports an adverse-inference instruction, dismissal, or default. Negligence does not.

☐ Check the forum. Several states retain a negligence-based adverse inference that the federal rule forecloses.

☐ Document your own compliance before you accuse anyone. Spoliation motions invite counter-motions.

Stage 13 — Closing out

☐ Serve supplementations under Rule 26(e) before the discovery cutoff, not after.

☐ Confirm every exhibit you will use at summary judgment is authenticated — by admission, deposition, or declaration. See Rule 56.

☐ Assemble the deposition designations and counter-designations on the schedule the court sets.

☐ Check that everything you intend to offer was disclosed. Rule 37(c)(1) is the last trap in the case.

☐ Preserve objections for appeal. See taking and perfecting a civil appeal.

Deadline quick reference

Item Federal deadline
Rule 26(f) conference ≥21 days before the scheduling conference or order
Initial disclosures 14 days after the Rule 26(f) conference
Interrogatory responses 30 days
Document request responses 30 days
Requests for admission 30 days — ⚠ deemed admitted if no response
Rule 45 subpoena objections 14 days, or before the compliance date if earlier
Expert reports Per scheduling order; default 90 days before trial
Rebuttal experts 30 days after the disclosure being rebutted

The five failures that cost the most

  1. No hold, or a hold nobody enforced. Everything downstream is contaminated.
  2. A missed requests-for-admission deadline. Automatic, self-executing, and sometimes case-dispositive.
  3. An undisclosed expert or witness. Rule 37(c)(1) exclusion applies without a motion.
  4. An unprepared corporate designee. The organization's own testimony becomes the other side's exhibit.
  5. Boilerplate objections with no statement about withholding. It converts a routine production into a fee award against you.

Physical evidence preserved (item, location, chain of custody)
Release date and authorization

☐ Name a single person responsible. Holds fail when they belong to everyone.

☐ Include vendors and cloud providers. Data you do not host is still data within your control.

☐ Record device model and account identifiers for departing employees before the device is wiped.

Worksheet: scoring a document request before you serve it

For each request, answer four questions. If any answer is "no," rewrite it.

  1. Is it bounded in time? An unbounded request draws an overbreadth objection that is usually correct.
  2. Could a stranger to the case find the documents from the description alone? If not, it is too vague.
  3. Does it ask for the answer or for the haystack? "Documents sufficient to show" beats "any and all."
  4. Have you specified the form of production? Native for spreadsheets, databases, and anything where the formula, timestamp, or author is contested.

⭐ A set of twelve precise requests outperforms a set of sixty vague ones, and it does so in half the time, because it does not generate the objection-conference-motion cycle that consumes the calendar.

Worksheet: evaluating a response you received

For each request, mark one:

☐ Complied — documents produced, no objection. ☐ Complied with objection, nothing withheld — the response says so expressly. Nothing to do. ☐ Objected and withheld — the response says documents are being withheld. This is your motion. ☐ Silent — the response objects and does not say whether anything is withheld. ⚠ This is the most common defect and the easiest to win on. Write the letter. ☐ Deferred — "will produce on a rolling basis." Get a date in writing, or the rolling basis rolls past the cutoff.

Then check three global items:

☐ Was a privilege log served, and does it have real entries rather than repeated boilerplate? ☐ Were interrogatory answers verified under oath by the party? ☐ Did the production include the metadata fields the protocol required?

For the parallel exercise in a matter that will be tried without counsel, see filing and trying a small claims case and the self-represented litigant's toolkit, where the same discipline applies with far fewer tools.
