How a Deposition Summary Should Handle Errata Corrections

The Transcript Isn’t the Last Word. Your Deposition Summary Shouldn’t Act Like It Is.

Most people assume a deposition transcript is fixed once it’s printed. It isn’t. After the deposition, the witness gets to change their testimony. Under Federal Rule of Civil Procedure 30(e), a deponent who asks in time has thirty days after the transcript becomes available to review it and file an errata sheet, listing changes in form or substance, with reasons. Sometimes those changes are trivial, a misspelled name, a fixed typo. Sometimes a witness moves an answer from yes to no. And here is the quiet problem: a deposition summary built from the transcript alone can be describing a record that the witness has already partly rewritten.

A quick grounding, since this sits where litigation meets a lot of paper. A deposition summary condenses sworn testimony into a shorter, organized document with references back to the exact page and line, so a legal team can work from the testimony without rereading all of it. When an errata sheet exists, the summary’s job quietly expands: it has to reflect both what the witness said and what they later changed. Miss that, and the summary is a confident snapshot of a moment that has passed.

Why does an errata correction matter enough to sweat over? Because it can move the testimony, and because both versions stay in the record.

A witness who answered one way at the deposition and changed the answer on the errata sheet has created two versions of the same fact. Both are part of the record, and for the attorney the gap between them is often the interesting part. A substantive change, and the reason the witness gave for it, can be as useful as the testimony itself. So a summary that quietly adopts the corrected answer, or one that ignores the errata and keeps the original, hides exactly the thing a reader needs to see. The value is in showing both, so the change is visible rather than buried.

Not every errata entry deserves the same handling, though, and this is where a summary earns its keep. Changes to form, a misspelled name, a transcription error, a clarified word, leave the testimony intact and can be handled quietly. Changes to substance, an answer reversed, a number altered, a qualifier added that shifts the meaning, are a different animal, and those are the ones a summary should flag clearly. Reading the errata sheet against the transcript to separate the housekeeping from the material changes is most of the work, because it points the attorney at the corrections that could actually affect the case instead of making them re-read every line.

The mechanics are simpler than they sound: show both states of the testimony, each cited. The summary notes the original answer with its page and line, and the errata correction with its entry on the errata sheet, plus the reason the witness gave if one is stated. Neither replaces the other. Keeping the original answer matters, because it does not disappear when the witness changes it. The original testimony can still be used, and an attorney needs to see what was said before the correction as clearly as what was said after.

That last point is worth sitting with, because it is where a well-meaning summary can quietly do harm. A summary that silently updates to the corrected answer can mislead the very team relying on it. If it shows only the errata version, an attorney preparing for trial may never realize the witness said something different under oath first, and that original answer is frequently the one worth raising. Showing both, cited on both sides, means the attorney decides which version to use and when, instead of the summary deciding for them by keeping only one. The complete, two-version record is more useful than a tidy single answer, because the discrepancy is usually where the value lives.

A word on AI, since it does a lot of this matching now. AI can line up each errata entry with the original page and line it changes, flag where an answer was altered, and do it faster than a person cross-referencing by hand. What it cannot reliably do is tell a substantive change from a formatting one in context, or judge which corrections actually matter to the case. So the dependable version pairs that speed with a trained reviewer who reads the change in context, confirms it against both the transcript and the errata sheet, and flags the ones that move the testimony. The tool aligns the versions. The reviewer decides which changes to surface and how.

And there’s a line worth naming. A deposition summary records what the witness originally testified to and what they changed on the errata sheet, cites both, and flags the material changes. It does not decide whether an errata change is proper or admissible, whether the stated reason is credible, or what the change means for the case. Those calls belong to the attorney. The summary’s only job is to make both versions of the testimony visible and traceable, so counsel can act on the complete record instead of one frozen before the corrections arrived.

So treat the transcript as a draft the witness can still edit, and treat the summary the same way. Reflect the errata, keep both versions, cite each, flag what’s substantive, and leave the judgment to the people who make it. Do that, and the summary describes the actual, current state of the testimony, rather than a snapshot the record has already outrun.

If your deposition summaries are built from transcripts but not the errata that follows them, that gap is worth closing, because the version you’re relying on may be missing the change that matters. LezDo TechMed prepares deposition summaries that reflect the errata and keep both versions traceable to the line. You can estimate a summary to see how the corrections are handled.
