Preparing a Witness for Deposition

Catch where a witness's account changed before the deposition, with citations on every finding.

Your witnesses are prepared when you know what's coming. For most witnesses that means rereading every prior statement, noting where the account changed, and drafting a first set of questions. A missed difference between two statements can be the best point you never used.

This lesson answers: what will this witness say and where has the account changed? Three prompts build prep questions from a transcript, surface inconsistencies across prior statements, and draft a plain-language witness summary. Two additional prompts provide more information.

Before you start

  • Selection controls the answer. The Assistant reads only what you select, so include every version of the witness's account.
  • Name the document, set a number and a structure, and specify the voice. Ask for the document and provision behind each point.
  • Fill in the [brackets]. Replace each one with the specifics from your matter, such as the witness, the date, the topics and the documents, before you run the prompt.

Prompts

1. Build prep questions from a transcript

Select the witness's prior recorded statement or transcript. Use this instead of "Give me some deposition questions." Look for questions tied to specifics in the statement and grouped under your headings. The questions are suggestions for the attorney to accept, change or reject. Open a few citations to confirm the statement says what each question assumes.
Review [witness]'s statement from [date]. Draft 12 deposition prep questions grouped under three headings: [topics]. Write each question the way I'd ask it in the room.

2. Surface inconsistencies across statements

Select every version of the witness's account: incident reports, recorded statements, declarations and prior testimony. Turn on Think Longer, which enables deeper reasoning and may increase response time, because this prompt compares one account across several documents. Use this instead of "Does anything here look off?" Open both citations behind each inconsistency.
Compare [witness]'s account of these events across [documents]. List every factual inconsistency. For each one, name the two documents that conflict and describe what each one says.

3. Draft a plain-language witness summary

Select the full matter file for the witness. Turn on Think Longer, which enables deeper reasoning and may increase response time, because this prompt reasons across the whole file. Use this instead of "Summarize this." The summary is a draft for the attorney to accept, change or reject, and the attorney decides what to ask. Check the flagged inconsistencies against Step 2.
Draft a one-page, plain-language summary of [witness]'s expected testimony for the deposition prep binder. Include a short section flagging the inconsistencies I need to probe.

Optional: Pull the facts into one list

Select the document and the rest of the file. Use this to build a checklist of specifics before the deposition. Open a few citations to confirm each item.

Optional: Find every discussion of a topic

Select the full matter file. Use this to see where a witness addressed a topic over time. Open the citation behind each entry to confirm the witness discusses the topic there.
