Somewhere in your office is a transcript — 240 pages of a defense medical expert, or a defendant driver, or your own client — and at some point between now and trial, you'll need what's in it without re-reading it. That's the whole purpose of a deposition summary: converting testimony into something usable at the speed of litigation.
But "summarize this deposition" is an incomplete instruction, because summaries come in three standard formats, each engineered for a different job. Order the wrong one and you'll have a perfectly accurate document that doesn't do what you needed. Here's the working reference — what each format is, what it's for, and the same fictional testimony rendered all three ways so you can see the difference at a glance.
(Fictional case, fictional witness: defendant driver in our recurring rear-end MVA, deposed for six hours, 240-page transcript.)
Page-line: the trial workhorse
A page-line summary condenses testimony in transcript order, every entry pinned to its page and line numbers:
12:8–14:2 — Admits he was "probably" looking at GPS in the minute before impact; doesn't recall when he last saw plaintiff's vehicle.
14:3–15:19 — Estimates own speed at 40–45 mph; speed limit 35 (acknowledged at 15:7).
31:4–33:11 — Phone records: confirms number, denies texting; "couldn't say" whether navigation was in use (32:20).
The format's job is citation. Page-line is what you want when the testimony will be used against someone: impeachment at trial, motion exhibits, designation work. The fastest path from "didn't he admit—?" to the exact lines, mid-cross. Cost note: it's also the most labor-intensive format, because it accounts for the whole transcript in order — you're paying for completeness, and for trial-bound testimony it's worth every entry.
Topical: the strategy view
A topical summary reorganizes the same testimony by subject, regardless of where in the six hours it surfaced:
DISTRACTION. Admits probable GPS use in the minute before impact (12:8); "couldn't say" if navigation active during call (32:20); phone in dash mount, screen on (47:3).
GPS admissions at 12:8 and 89:14 differ — "probably" vs. "briefly glanced."SPEED. Self-estimate 40–45 in a 35 (14:3, 15:7); no memory of braking before impact (51:12).
See what the format does? Witnesses don't testify in tidy categories — the distraction story here was scattered across three passes, forty pages apart, and the topical summary is what catches the "probably" at page 12 becoming "briefly glanced" by page 89. The format's job is analysis: case evaluation, expert prep, mediation outlines, drafting the demand's liability section, prepping the next deposition in the case. When the question is "what do we actually have on X?", topical answers it.
Chronological: the story view
A chronological summary rebuilds testimony into the timeline of events as the witness tells it — what happened, in the order it happened, with citations carried along:
Before impact: Left work ~5:40 (8:14); entered Highway 12 ~5:50 (9:2); GPS routed around traffic (11:8); "probably" glanced at GPS in final minute (12:8); never saw plaintiff's vehicle before impact (13:22).
Impact and after: No braking recalled (51:12); first memory post-impact is airbag (52:4)…
The format's job is narrative coherence — and narrative gaps. Chronological summaries shine when the sequence is the dispute (who saw what when), when reconciling one witness's timeline against another's or against the physical evidence, and when preparing accident reconstruction or medical causation experts who think in timelines. If you've read this series' piece on medical chronologies, this is the same instinct applied to testimony: rebuild the timeline, and the holes announce themselves.
The selection rule, and a practical note on combinations
Page-line for impeachment, topical for strategy, chronological for story.The shorthand to keep
Or by destination — heading to trial: page-line. Heading to mediation or evaluating the case: topical. Fighting about sequence or prepping experts: chronological.
Real cases often justify a combination, and there's a cost-saving sequence to know: the deep transcript read happens once, so a topical summary added to a page-line order costs far less than either built alone — most of the work is already done. The expensive mistake is serial single orders months apart, paying for the same read twice. If trial is realistic, say so at the start; the work gets structured so later formats build on the first.
On turnaround: a standard transcript day runs predictable hours to summarize, format depending — which means realistic scheduling, not heroics, gets summaries back before they're needed. (Specifics and current rates are on the pricing page; for a multi-deposition triage system, that post is coming later in this series.)
One last note, because it's the question behind the question: a summary is only as useful as its accuracy under pressure. Every format above gets used in moments where a wrong citation costs something — mid-cross, mid-motion, mid-negotiation. That's the actual product: not shorter documents, but citations you can stand on without checking.
