Summary. This checklist sets out, phase by phase, the tasks a litigator should complete before cross-examining an adverse witness, at deposition or at trial, in federal civil litigation. It covers defining goals from the elements, gathering intelligence on the witness, assembling impeachment material, controlling exhibits, confirming the governing evidence and procedure rules, and building a chapter outline. Separate phases address deposition-specific and trial-specific steps, expert witnesses, preparing your own witnesses against Reptile and Reid-style questioning, and an ethics check before the examination. Each item links the governing rule or case and adds a short practical note. Red-flag boxes, a deadlines table, a short worked example, and a list of common failure points close the checklist.

How to use this checklist

Cross-examination looks like improvisation and is almost entirely preparation. This checklist is organized in the order the work is usually done, from the case theory down to the night before. Phases 1 through 5 apply to every cross-examination. Phase 6 is for depositions, Phase 7 for trial, Phase 8 for experts, and Phase 9 for preparing your own witnesses to withstand the other side's cross. Phase 10 is an ethics check that should be run on every outline before use.

Copy the checklist into the matter file for each key witness, assign an owner to each item, and date it when complete. Items marked (D) apply mainly to depositions and (T) mainly to trial; unmarked items apply to both.

The theory behind the techniques referenced here is explained in Cross-Examination Methods Compared: Pozner-Dodd, Younger's Ten Commandments, the Reptile, and the Reid Technique. The step-by-step process for a deposition is in Cross-Examining an Adverse Witness at Deposition: A Practical Guide. Fillable templates for the outline, impeachment sequences, and witness preparation modules are in the Cross-Examination Toolkit: Chapter Outlines, Impeachment Sequences, and Reptile Defense Scripts.

Phase 1: Goals and case theory

  • Write the theory of the case in two or three sentences. Every chapter of the cross must serve it. If a fact does not help the theory or hurt the other side's, cut it.
  • List the elements of each claim and defense and mark which elements this witness can prove, disprove, or complicate. Use the pattern jury instructions for your circuit as the element list.
  • Write the admissions list: the exact sentences you want the witness to agree to, phrased as you would quote them in a brief or closing.
  • Decide the purpose of the examination. Discovery, lock-in, trial preservation, summary judgment record, or trial cross. Most depositions combine discovery and lock-in; trial cross is never discovery.
  • Decide what not to ask. List subjects where the witness can hurt you and the reward is small. Younger's rule against asking questions you cannot answer applies with full force at trial.
  • Identify the scope limit. At trial, cross is limited to the subject matter of direct and credibility under Fed. R. Evid. 611(b) unless the court permits more. At deposition, the scope is the discovery scope of Fed. R. Civ. P. 26(b)(1).
  • (T) Plan the closing argument passage this cross will support. Write the two or three sentences of closing that will cite the cross. If you cannot, the cross lacks a goal.

Phase 2: Witness intelligence

  • Collect every document the witness wrote, received, or signed that bears on the admissions list, and every reference to the witness in other documents.
  • Collect all prior sworn statements: depositions in this and other cases, declarations, affidavits, verified pleadings, verified interrogatory answers, hearing and trial testimony, and regulatory submissions. Note the oath status of each, because only statements made under penalty of perjury at a trial, hearing, other proceeding, or deposition are substantive evidence under Fed. R. Evid. 801(d)(1)(A).
  • Collect unsworn prior statements: emails, texts, chats, social media posts, interviews, articles, presentations, recorded calls. These are usable to impeach under Rule 613 and, if made by a party or its agent, as admissions under Rule 801(d)(2).
  • Identify bias, interest, and motive. Compensation tied to the outcome, employment by a party, family or business relationships, pending claims, fee arrangements (for experts), and prior adverse dealings. Bias impeachment is constitutionally protected in criminal cases (Davis v. Alaska, 415 U.S. 308 (1974)) and recognized under the Evidence Rules (United States v. Abel, 469 U.S. 45 (1984)).
  • Run a criminal history check where permitted and relevant, and evaluate admissibility under Fed. R. Evid. 609. Crimes involving a dishonest act or false statement are admissible regardless of punishment; other felonies are subject to balancing; convictions more than ten years old require written notice and a heightened showing.
  • Identify specific instances of untruthful conduct with a good-faith basis. Under Rule 608(b), you may ask about them on cross but cannot prove them with extrinsic evidence, so you take the witness's answer.
  • Search for prior testimony and public statements. Court dockets, transcript services, professional publications, conference videos, and the witness's social media.
  • Read the other side's witness's deposition of other people, to learn what your adverse witness's colleagues said about the same events.
  • Build a witness-specific chronology keyed to documents (Bates numbers) and prior statements (page and line).

Red flag: the undated, unauthenticated screenshot. A social media post the witness supposedly made is impeachment only if you can tie it to the witness. Preserve it properly, and have a plan to authenticate it under Fed. R. Evid. 901 if the witness denies it. See Authenticating Website Evidence: A Practical Checklist.

Phase 3: Documents and exhibits

  • Select exhibits for each chapter and order them in the sequence you will use them.
  • Confirm the exhibit numbering system (case-wide numbering avoids conflicting exhibit numbers across depositions).
  • Prepare clean copies: one for the witness, one for each counsel, one for the reporter or court, and your working copy with highlights and page references. For remote examinations, set up the exhibit-sharing method in advance.
  • Prepare foundation questions for authentication under Rule 901 and, for business records, the elements of Rule 803(6). Check whether a certification under Rule 902(11) is available or has been served.
  • Check privilege and confidentiality status of every exhibit: protective-order designations, clawback notices under Fed. R. Evid. 502, and sealing requirements.
  • Prepare impeachment packets: for each prior inconsistent statement, a copy of the source with the passage marked, the page and line, the date and oath circumstances, and a copy for opposing counsel (who is entitled to see it on request under Rule 613(a)).
  • (T) Prepare deposition clips for video impeachment, with page and line citations and a fallback of reading the transcript.
  • (T) Check illustrative aids and summaries. Illustrative aids are now governed by Fed. R. Evid. 107 (effective December 1, 2024), which allows them to help the jury understand evidence or argument if their utility is not substantially outweighed by unfair prejudice, confusion, or delay, and provides that they are not evidence and do not go to the jury room unless all parties consent or the court orders otherwise; summaries of voluminous records by Rule 1006. Disclose demonstratives as the court's pretrial order requires.

Phase 4: The rules for this examination

  • Confirm leading questions are available. Leading is ordinarily permitted on cross, and on direct examination of a hostile witness, an adverse party, or a witness identified with an adverse party, under Rule 611(c).
  • (D) Read Rule 30's conduct provisions and any local rule or standing order: Fed. R. Civ. P. 30(c)(2) (concise objections; instructions not to answer only for privilege, court-ordered limits, or a Rule 30(d)(3) motion) and Rule 30(d)(1) (seven-hour limit).
  • (D) Identify your court's rule on attorney-witness conferences. Hall v. Clifton Precision, 150 F.R.D. 525 (E.D. Pa. 1993), bars conferences other than on privilege, including during breaks; other courts are more permissive, for example Ngai v. Old Navy, 2009 WL 2391282 (D.N.J. 2009).
  • Confirm the prior-statement procedure. Under Rule 613(b), as amended effective December 1, 2024, extrinsic evidence of a prior inconsistent statement ordinarily may not be admitted until the witness has been given an opportunity to explain or deny it and the adverse party an opportunity to examine on it (unless the court orders otherwise). Plan to confront before offering the document. The rule does not apply to an opposing party's own statement under Rule 801(d)(2).
  • (T) Determine whether a Rule 615 order has been or should be requested. Under Fed. R. Evid. 615, as amended in 2023, an order excluding witnesses from the courtroom does not by itself bar witnesses from learning about trial testimony outside the courtroom; request any broader order expressly.
  • (T) Check pending and decided motions in limine that affect the cross: prior bad acts under Rule 404(b), subsequent remedial measures under Rule 407, settlement communications under Rule 408, insurance under Rule 411, and unfair prejudice under Rule 403. Under Rule 103(b), a definitive pretrial ruling preserves the objection; a tentative ruling does not.
  • (T) Confirm the Rule 32 route for any deposition you will use: impeachment of any witness under Rule 32(a)(2), adverse party for any purpose under Rule 32(a)(3), or unavailable witness under Rule 32(a)(4).
  • (T) Prepare for completeness demands under Rule 32(a)(6) and Fed. R. Evid. 106. Know which adjacent passages the other side will demand, and decide whether to read them yourself first.

Red flag: impeaching with a statement you cannot prove. If the witness denies making a prior statement and the statement is not in a document you can authenticate or a transcript, you may be stuck with the denial, and on a collateral matter extrinsic proof may be excluded entirely. Do not start an impeachment you cannot finish.

Phase 5: The outline

  • Divide the cross into chapters, each with one goal and ending in one fact you want remembered.
  • Write lock questions as statements, one fact each. "You signed the inspection report on March 4." Not "You signed and dated the report after the inspection, didn't you?"
  • (D) Precede each lock with a funnel: open questions, narrowing questions, and exhaustion ("anything else?").
  • Map each fact to its source (exhibit and page, or transcript page and line) in a margin column.
  • Order chapters with the strongest first and last (primacy and recency) and the risky or anger-provoking chapters late.
  • Budget time per chapter, with the essential chapters in the first two-thirds of the available time.
  • Write the impeachment chapters using the commit, credit, confront sequence (templates in the toolkit).
  • Mark the "stop" point in each chapter, the last question before the one too many.
  • (T) Prepare a one-page "cross card" with chapter titles, key exhibits, and impeachment page and line, for use if the outline must be abandoned.
  • Rehearse aloud, preferably with a colleague playing the witness and another playing opposing counsel making objections.

Phase 6: Deposition-specific steps (D)

  • Serve a proper notice under Rule 30(b)(1) with the recording method under Rule 30(b)(3). Choose video if the testimony may be played at trial.
  • For nonparties, serve a Rule 45 subpoena with any document request, and give the other parties notice before serving a documents subpoena under Fed. R. Civ. P. 45(a)(4).
  • For a Rule 30(b)(6) deposition, draft topics with reasonable particularity and confer in good faith with the organization about them as Rule 30(b)(6) has required since 2020. See Rule 30(b)(6) Deposition Preparation Checklist: A Practical Checklist.
  • Schedule the deposition after the documents and after lower-level witnesses, where possible.
  • Prepare the opening: stipulations (be explicit; avoid "the usual"), admonitions, medication and impairment questions, and questions about preparation and documents reviewed (for Rule 612 and Sporck v. Peil, 759 F.2d 312 (3d Cir. 1985) issues).
  • Prepare an obstruction plan: the record-making script for speaking objections and improper instructions, the judge's discovery-dispute procedure, and a draft motion outline under Rule 37(a)(3)(B)(i) and Rule 30(d)(2).
  • Decide which impeachment to use now and which to save. Use now if needed for summary judgment or if the witness may be unavailable; otherwise consider saving.
  • Plan the close: outstanding requests on the record, whether to hold the deposition open, and the review-and-sign request under Rule 30(e).
  • For remote depositions, run the technology check and agree the remote protocol. See Remote Deposition Checklist: A Practical Checklist.

Phase 7: Trial-specific steps (T)

  • Watch or read the direct examination closely and adjust the outline. Strike chapters the direct made unnecessary; add chapters for new claims the witness made.
  • Note every new fact in direct that contradicts the deposition, with page and line ready for impeachment under Rule 32(a)(2) and Rule 613.
  • Stay within scope under Rule 611(b), or ask the court for leave to go beyond it (knowing you then lose the right to lead on the new matter).
  • Apply Younger's restraint. Be brief; short questions; always lead; do not ask what you do not know (or do not care about); listen; do not quarrel; do not let the witness repeat direct; do not let the witness explain; avoid the one question too many; save the explanation for summation.
  • Prepare for the non-responsive witness: repeat the question verbatim; ask the court to instruct the witness to answer; move to strike non-responsive portions.
  • Plan the impeachment logistics: who hands the exhibit, who queues the video clip, and how to show the passage to opposing counsel.
  • Prepare for redirect. Anticipate rehabilitation (prior consistent statements are admissible under Rule 801(d)(1)(B) only in limited circumstances, and under Tome v. United States, 513 U.S. 150 (1995) only if made before the alleged motive to fabricate arose) and plan a short recross if allowed.
  • Have objections ready for the other side's tactics during your cross (e.g., the witness volunteering hearsay) and during theirs (leading on direct, Golden Rule arguments in closing).

Red flag: the Golden Rule slip. An argument asking jurors to put themselves in a party's position is improper, at least as to damages, in every circuit to consider it; the D.C. Circuit ordered a new trial on that ground in Caudle v. District of Columbia, 707 F.3d 354 (D.C. Cir. 2013). Object contemporaneously and ask for a curative instruction; silence risks waiver. For pretrial motions, see Motion in Limine Checklist: A Practical Checklist.

Phase 8: Expert witnesses

  • Obtain the full Rule 26(a)(2)(B) disclosure: opinions and bases, facts or data considered, exhibits, qualifications and publications for ten years, prior testimony for four years, and compensation. See Fed. R. Civ. P. 26(a)(2)(B).
  • Note what is protected. Draft reports and most attorney-expert communications are protected under Rule 26(b)(4)(B)-(C), except communications about compensation, facts or data the attorney provided and the expert considered, and assumptions the attorney provided and the expert relied on. Those three exceptions are prime cross material.
  • Map the cross to Rule 702. Since the 2023 amendment, the proponent must show by a preponderance that the testimony meets each requirement of Fed. R. Evid. 702, including that the opinion reflects a reliable application of the methods to the facts. Chapters: qualifications for this opinion; sufficiency of facts and data; reliability of method; application.
  • Build a Daubert chapter on testing, peer review, error rate, standards, and general acceptance, per Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993) and Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999).
  • Identify the bases to disclose on cross under Rule 705 and inadmissible facts the expert relied on under Rule 703.
  • Prepare learned-treatise impeachment under Rule 803(18): the treatise must be established as reliable authority, and statements are read into evidence but not received as exhibits.
  • Collect the expert's prior testimony and publications that contradict the current opinion.
  • Never ask the expert "why." Experts are trained to explain.

Expert-specific checklists are in Expert Deposition Preparation Checklist: A Practical Checklist and Expert Disclosure and Daubert Challenge Checklist: A Practical Checklist.

Phase 9: Preparing your own witness for the other side's cross

  • Explain the process: the oath, the format, objections, breaks, the seven-hour limit, video, and the court's conference rule.
  • Review the key documents with the witness, mindful that documents used to refresh recollection may be discoverable under Rule 612.
  • Practice the lock-in pattern. Teach the witness to agree only to what is accurate in a summary question and to identify which part is wrong.
  • Reptile module. Teach the witness to recognize safety-rule absolutes ("always," "never," "number one priority," "needlessly"), to answer truthfully with context ("It depends on the conditions, because..."), to distinguish company guidelines from the legal standard, and to decline legal conclusions ("I'm not a lawyer").
  • Reid module. Teach the witness to recognize a tonal shift, to reject softened mischaracterizations of their conduct, to reject false binaries ("Neither; what happened was..."), and not to reciprocate a friendly opening with volunteering.
  • Practice "I don't recall" honestly. Lack of memory is a valid answer only when true. A feigned lack of memory is evasion, and an evasive answer is treated as a failure to answer under Rule 37(a)(4).
  • Run a mock cross with a colleague who uses the techniques the other side is known for.
  • Plan objections for compound, mischaracterizing, argumentative, and legal-conclusion questions, stated concisely under Rule 30(c)(2).
  • For corporate defendants, prepare a motion in limine targeting specific Golden Rule, community-safety, and send-a-message arguments and specific deposition clips. See Drafting and Opposing Motions in Limine: A Practical Guide.

Red flag: coaching that crosses the line. Preparation may cover recollection, documents, likely questions, and demeanor. It may not include suggesting false testimony. ABA Model Rule 3.4(b) forbids counseling or assisting a witness to testify falsely, and Model Rule 3.3 imposes remedial duties if a witness offers material false evidence, including at a deposition.

Phase 10: Ethics check before use

  • Good-faith basis for every insinuating question. Model Rule 3.4(e) bars alluding at trial to matters the lawyer does not reasonably believe are relevant or supported by admissible evidence.
  • No misrepresentation of evidence to the witness. Police interrogators may sometimes misstate evidence (the Supreme Court tolerated it in Frazier v. Cupp, 394 U.S. 731 (1969)); lawyers may not, under Model Rules 4.1(a) and 8.4(c).
  • No questions whose only purpose is to embarrass or burden. Model Rule 4.4(a), Rule 611(a), and Rule 30(d)(3).
  • No personal opinion on credibility or justness of the cause in questions or argument (Model Rule 3.4(e)).
  • Unrepresented witnesses: do not imply disinterest, and do not give legal advice other than to secure counsel (Model Rule 4.3).
  • Confirm sanctions exposure is understood on both sides: Rule 30(d)(2), Rule 37, and 28 U.S.C. § 1927.

Phase 11: The day before and the day after

Deadlines table

Event Deadline Source
Notice of deposition "Reasonable written notice" to every party Rule 30(b)(1)
Documents requested from party deponent 30 days after service of the Rule 34 request (absent agreement or order) Rule 30(b)(2); Rule 34(b)(2)(A)
Notice to parties of a documents subpoena Before the subpoena is served on the nonparty Rule 45(a)(4)
Rule 30(b)(6) conferral Before or promptly after the notice or subpoena is served, and continuing as necessary Rule 30(b)(6)
Deposition length 1 day of 7 hours, absent stipulation or order Rule 30(d)(1)
Errata review and signature 30 days after notice that the transcript is available, if review was requested before completion Rule 30(e)(1)
Expert disclosures At least 90 days before trial, or 30 days after the other party's disclosure for rebuttal, absent stipulation or order Rule 26(a)(2)(D)
Pretrial disclosures (witnesses, deposition designations, exhibits) At least 30 days before trial, absent order Rule 26(a)(3)(B)
Objections to deposition use and exhibits Within 14 days after pretrial disclosures, absent order Rule 26(a)(3)(B)
Written notice of intent to use a conviction more than 10 years old Reasonable notice, in advance Rule 609(b)(2)
Motions in limine Per scheduling or pretrial order Rule 16

Local rules and case management orders often change these defaults. Calendar from the order, not the rule.

Short worked example

Delgado v. Bayline Pharmacy Services is a fictional employment case. The plaintiff, a pharmacist named Rosa Delgado, alleges she was fired for reporting dispensing errors. The defense will call her former supervisor, Ken Mattox, who will say she was fired for attendance problems.

Plaintiff's counsel works through the checklist. Phase 1 produces a theory (the attendance concerns appeared only after the report) and an admissions list of six facts. Phase 2 turns up Mattox's deposition, his performance review of Ms. Delgado (rating her "exceeds expectations" two months before the report), a Slack message in which he wrote "this complaint is going to be a problem for us," and a bonus plan tied to regional compliance metrics (bias). Phase 3 assembles the review and the message with foundation questions. Phase 4 confirms that the court's in limine ruling excluded a separate HR investigation of Mattox, so that subject is off limits. Phase 5 produces five chapters: the review; the timing of the attendance write-ups; the Slack message; the bonus; and impeachment on one point where his deposition said he "never discussed" the report with HR.

At trial, Mattox testifies on direct that he raised attendance concerns "for months." Counsel adds a chapter, commits him to "for months," credits the deposition, and reads the page and line where he said the first attendance concern was raised "in the spring," after the report. She asks nothing about why, and sits down after the bonus chapter, saving the inference for closing.

Common failure points

  • No admissions list, so the cross covers topics but proves nothing.
  • Leading in discovery and opening up at trial: precisely backward.
  • Impeachment material without page and line, or without a copy for opposing counsel.
  • An unauthenticated document the witness denies, with no backup foundation witness.
  • Ignoring an in limine ruling and opening a door, or drawing a mistrial motion.
  • Expert cross that asks "why" or argues methodology with the expert instead of exposing it.
  • A Reptile-prepared opponent and an unprepared corporate witness.
  • Waiting until the transcript arrives to calendar the errata window.
  • No time budget, so the most important chapter is never reached.

This document is general information, not legal advice for any particular situation; the law, local rules, and judges' practices vary, and the facts matter.
