# Deposition Errata Sheet

Manages the FRCP 30(e) errata process: submitting corrections for your witness or challenging an opposing witness's improper changes.

## Prerequisites

- **Deposition transcript** with page/line numbers
- **Review requested** on the record before deposition concluded
- **30-day deadline** from reporter's notification of transcript availability
- **Audio/video recording** (if available) for verifying transcription errors
- **Jurisdiction** — local precedent on permissible change scope

## Quick Start

1. Confirm review was timely requested and deadline has not lapsed
2. Identify whether you are **submitting** corrections (Part A) or **challenging** opposing corrections (Part B)
3. Research controlling local precedent on substantive changes
4. Draft errata sheet or challenge motion using the workflows below

## Jurisdictional Split on Substantive Changes

| View | Rule | Key Cases |
|------|------|-----------|
| **Permissive** | Form and substance allowed; original preserved; addressed on cross | *Greenway v. Int'l Paper Co.*, 144 F.R.D. 322 (W.D. La. 1992) |
| **Restrictive** | Only transcription errors; substantive changes may be stricken | Various district courts |
| **Intermediate (majority)** | Substantive changes permitted but contradictory ones disregarded; reasons scrutinized; usable for impeachment | *Hambleton Bros. Lumber v. Balkin*, 397 F.3d 1217 (9th Cir. 2005); *Burns v. Bd. of Cty. Comm'rs*, 330 F.3d 1275 (10th Cir. 2003) |

**Always verify controlling precedent before submitting or challenging errata.**

## Part A — Submitting Errata (Your Witness)

### Change Permissibility

| Category | Examples | Permissible? |
|----------|----------|--------------|
| Typographical error | Name misspelled, number wrong | Yes |
| Technical/industry term | Acronym expanded wrong, jargon misheard | Yes |
| Obvious mishearing | "I didn't" vs. "I did"; audio confirms | Yes |
| Witness cut off | Answer incomplete in transcript | Yes |
| Substantive clarification | "What I meant was..." | Scrutinized |
| Memory refreshed post-depo | Reviewed docs, recalls differently | Scrutinized |
| Complete reversal | "Yes" to "No" | Improper |
| Adding new facts | Facts not discussed at deposition | Improper |
| Damage control | Changing harmful admissions | Improper |

### Strategic Filter

Before correcting, ask:
- Does the error significantly misrepresent testimony or create a false admission?
- Can you articulate a legitimate, non-pretextual reason?
- Will the correction draw more attention than leaving it alone?
- Will opposing counsel convert the change into impeachment?

### Errata Sheet Template

```
                        ERRATA SHEET

Case:              [CASE NAME AND NUMBER]
Deponent:          [NAME]
Deposition Date:   [DATE]
Review Date:       [DATE]

I have reviewed the transcript of my deposition and request the
following corrections:

Page  Line  Reads                 Should Read           Reason
----  ----  --------------------  --------------------  --------------------



Subject to the corrections noted above, I affirm the transcript
is a true and accurate record of my testimony.

I declare under penalty of perjury that the foregoing is true
and correct.

Executed on _____________, at ________________.

                         _________________________________
                         [DEPONENT SIGNATURE / PRINTED NAME]
```

### Submission Checklist

- [ ] Review requested on the record before deposition closed
- [ ] 30-day deadline verified
- [ ] Full transcript reviewed with witness
- [ ] Compared to audio/video if available
- [ ] Each change evaluated for propriety and credibility cost
- [ ] Clear, non-pretextual reason stated for each change
- [ ] Witness signed under oath
- [ ] Served on all parties and provided to court reporter

## Part B — Challenging Opposing Errata

### Red Flags

- Complete reversal of key testimony
- Facts added that were never discussed
- Every change benefits the changing party
- Vague or conclusory reasons ("error in transcript")
- Changes timed to pending motion deadlines

### Response Options

| Option | When to Use | Approach |
|--------|-------------|----------|
| **Motion to Strike** | Restrictive jurisdiction; substantive changes | Argue changes exceed 30(e) scope; request reliance on original |
| **Opposition to Reliance** | Opposing party cites changed testimony in briefing | Attach original excerpt; argue changes are pretextual |
| **Impeachment at Trial** | Preserve credibility attack | Use original answer, then expose the change and timing |

### Impeachment Framework

```
Q: At your deposition you testified [ORIGINAL ANSWER], correct?
Q: You gave that answer under oath?
Q: After the deposition you submitted an errata sheet changing that answer?
Q: You changed [N] answers total in your errata sheet?
Q: Every single change benefited your case, didn't it?
```

### Preemptive Testimony Lock-In

Use during deposition to limit errata abuse:
- "Is that your testimony today?"
- "You've had time to think about this question?"
- "You understand you can correct transcription errors but not change the substance of your answers?"

### Challenge Checklist

- [ ] Identified all substantive vs. typographical changes
- [ ] Researched controlling local precedent on permissible scope
- [ ] Selected response strategy (strike / oppose reliance / impeach)
- [ ] Preserved original transcript for trial impeachment
- [ ] Considered whether supplemental deposition is warranted for new facts

## Common Pitfalls

- **Assuming permissive treatment**: Courts vary sharply — never assume unfamiliar districts allow substantive changes
- **Vague reasons**: Legally required and strategically critical; vague reasons invite adverse inference
- **Errata as damage control**: Never reverse testimony solely because it became inconvenient; ethics rules on candor apply
- **State court assumptions**: State rules differ from FRCP 30(e); verify the state analog before applying this framework
- **Forgetting original survives**: The changed version sits alongside the original, making every improper change a built-in impeachment document
