Deposition Summarization
Produces citation-backed deposition summaries. Every summary statement must include a pp. page:line range. Default to Format A unless the user specifies otherwise.
Quick Start
- Receive transcript text or file.
- Identify format: A (sequential), B (topic-based), or C (deep analysis).
- Summarize with
pp. page:line-page:line citations on every entry.
- Note objections, stipulations, exhibit references, and confidentiality designations.
Format A: Page-Line Summary
Sequential, transcript-order summary. Neutral language.
pp. 12:3-14:8 — Deponent described arriving at the facility at 8:30 AM
and meeting with [Name] in the conference room. [Ex. 3 marked and identified.]
pp. 14:9-16:22 — On cross-examination, deponent acknowledged signing the
memorandum (Ex. 4) but stated he did not read it before signing.
Format B: Topic-Based Summary
Groups testimony by subject. Each topic: 2-3 sentence neutral summary with citations.
## Employment History
Deponent worked at [Company] from 2018-2022 as Senior VP of Operations
(pp. 8:12-9:4), reporting directly to the CEO (pp. 9:15-10:8).
## Knowledge of Transaction
Deponent first learned of the acquisition in January 2022 (pp. 22:3-22:18)
and attended three related board meetings (pp. 23:1-25:14, 31:8-33:2, 45:6-47:11).
Format C: Deep Analysis
Includes Format A or B, plus these additional sections:
- Admissions Against Interest — Testimony harmful to deponent's party. Exact quotes with citations.
- Inconsistencies — Internal contradictions or conflicts with other testimony/documents.
- Impeachment Opportunities — Prior inconsistent statements, bias, lack of personal knowledge.
- Key Exhibits — Table format:
| Exhibit | Description | Pages Discussed | Authenticated? |
|---|
| Ex. 1 | [Description] | pp. 15:3-17:8 | Yes — pp. 15:10 |
- Credibility Assessment — Evasive answers, non-responsive testimony, "I don't recall" count with page ranges.
Pitfalls
- Never summarize without a
pp. page:line citation.
- Keep summary language neutral; reserve analysis for Format C sections only.
- Preserve exact quotes (in quotation marks) for admissions and key testimony.
