Errata Sheets as a Strategic Tool — and the Sham-Affidavit Trap

The errata sheet is one of the most underused — and most carelessly used — procedural mechanisms in deposition practice. FRCP 30(e) permits a deponent who has requested transcript review to "change the form or substance of the answer" within 30 days of being notified that the transcript is available. The procedural mechanics are well-established. The substantive law on what kinds of changes are permitted is anything but.

The federal courts have split sharply between a permissive approach (allowing substantive contradictory changes provided procedure is followed) and a restrictive approach (limiting permissible changes to transcription errors and clarifications). The Ninth Circuit's restrictive line, anchored in Hambleton Bros. Lumber Co. v. Balkin Enterprises, Inc., 397 F.3d 1217 (9th Cir. 2005), has gained increasing influence — and substantive errata changes now increasingly trigger sham-affidavit treatment at summary judgment.

This article is for PI attorneys who use or contest errata sheets and who want a current view of where the doctrine has moved.

The Procedural Framework

FRCP 30(e) sets out four procedural requirements that must be satisfied before any errata sheet has effect:

1. The deponent (or a party) must have requested transcript review during the deposition. This request is typically made on the record at the close of the deposition; the failure to request waives the right to review and correct.

1. The court reporter must certify that the request was made and that the transcript was made available for review.

1. The deponent must submit any changes within 30 days of being notified that the transcript is available.

1. The errata must include a statement of the reasons for each change.

Substantive defects on any of these procedural points are sufficient to invalidate the errata, regardless of the substantive nature of the changes. Practitioners on both sides should verify the procedural requirements before either filing or contesting an errata sheet.

The two procedural points that most commonly defeat errata sheets:

Failure to request review on the record. Many depositions close without an explicit request for transcript review. Defense counsel sometimes make a general statement ("the witness will read and sign") that satisfies the request; in other depositions the issue is overlooked entirely. Without the request, the right to correct is waived.

Late submission. The 30-day window runs from notification, not from the deposition date. The deponent must submit changes within the window or lose the right to make them.

The Permissive Approach

The permissive approach to errata sheets, sometimes associated with older Second Circuit precedent (Podell v. Citicorp Diners Club, Inc., 112 F.3d 98 (2d Cir. 1997), and its progeny), reads the "form or substance" language of Rule 30(e) literally. Under this approach, a deponent may make substantive changes to deposition testimony — even contradictory changes — provided the procedural requirements are met.

The reasoning: Rule 30(e) plainly permits changes "in form or substance." Substantive changes are within the rule's text. The original testimony is not stricken; it remains part of the record and can be used for impeachment. The errata simply supplies the deponent's revised position.

Under the permissive approach, the original deposition testimony and the errata-corrected testimony both come into evidence. The fact-finder weighs them. The errata is not excluded merely because it contradicts the original.

A number of district courts within the permissive circuits continue to follow this approach. Errata changing dates, distances, identities, and other substantive details have been permitted even when they significantly alter the case posture.

The Restrictive Approach

The Ninth Circuit's decision in Hambleton Bros. established the most influential restrictive approach. The court held that Rule 30(e) "is to be used for corrective, and not contradictory, changes." Substantive errata changes that materially alter the deponent's testimony are treated as "sham corrections" and may be struck.

The Hambleton facts illustrate the doctrine's application. The errata sheet was submitted only after the defendant filed a motion for summary judgment. The corrections were extensive and went to the substantive questions at issue in the motion. The Ninth Circuit affirmed the district court's order striking the errata, citing the tactical timing and the extensive nature of the changes.

The restrictive approach has spread beyond the Ninth Circuit. District courts in other circuits have applied similar reasoning, particularly where:

• The errata is submitted after a dispositive motion is filed.
• The changes are extensive and material to contested issues.
• The reasons given for the changes are conclusory or non-existent.
• The errata creates a new factual dispute that did not previously exist.

Under the restrictive approach, errata that fail this scrutiny are excluded. The original testimony stands, unchanged by the attempted correction.

The Sham-Affidavit Connection

The sham-affidavit doctrine — the rule that a party cannot defeat summary judgment by submitting an affidavit that contradicts the party's earlier sworn testimony — has become functionally integrated with errata practice in many circuits.

The connection: when an errata sheet contradicts the original deposition testimony in a way that creates a new factual dispute at summary judgment, courts increasingly apply sham-affidavit principles to evaluate whether the errata is genuine or strategic. The factors courts weigh include:

• The timing of the errata relative to the summary judgment motion.
• The extent and nature of the changes.
• The explanation offered for the changes.
• Whether the changes are consistent with documentary evidence and other testimony.
• Whether the deponent had a credible reason for the original testimony being incorrect.

An errata sheet that fails these factors is excluded at summary judgment under the sham-affidavit doctrine, and the original testimony controls. An errata sheet that passes them — typically because the changes are limited, well-explained, and not tactically timed — is treated as a genuine correction.

Strategic Uses of Errata

Despite the doctrinal risk, errata sheets remain valuable tools when used appropriately. Three uses earn their keep:

Transcription corrections. Witnesses commonly identify transcription errors — misheard names, misspelled places, technical terms that the court reporter rendered phonetically. These corrections are universally accepted across circuits, even the most restrictive.

Clarifications of compound or ambiguous testimony. Where the deposition transcript reflects an ambiguous answer — a witness who answered "yes" to a compound question without specifying which clause they meant to affirm — an errata sheet can clarify the intended meaning. Done early and explained well, this kind of clarification typically survives challenge.

Corrections supported by external evidence. A witness who testified inaccurately about a date, location, or document content based on memory may correct the testimony when contemporaneous records confirm the correct version. The supporting evidence makes the correction credible.

Uses to avoid:

• Corrections that contradict the witness's other testimony in the same deposition.
• Corrections made after a summary judgment motion is filed.
• Corrections that go to ultimate factual issues without supporting context.
• Corrections accompanied by no explanation or only a conclusory explanation.

Defending Against an Adverse Errata

When opposing counsel submits an errata sheet that contradicts favorable original testimony, the defending party has several options:

Motion to strike. Where the errata is procedurally defective or substantively contradicts the original testimony, a motion to strike the errata under Rule 30(e) is available. In restrictive circuits, the motion has a higher probability of success.

Reopening the deposition. Some courts have ordered a limited reopening of the deposition to allow questioning about the errata — when the changes were made, why they were made, what the deponent reviewed before making them. This often develops impeachment material that undermines the errata.

Use at trial regardless of the errata. The original testimony remains part of the record and is admissible for impeachment even where the errata is permitted as substantive testimony. The cross-examination architecture is to use the original testimony first and develop the contradiction, then address the errata as an after-the-fact recharacterization.

Sham-affidavit motion at summary judgment. Where the errata supports the opposing party's summary judgment position, a sham-affidavit motion is the primary tool. In restrictive circuits, the motion typically succeeds when the errata is material, contradictory, and tactically timed.

Practical Workflow for the Deponent's Side

For attorneys representing the deponent, the workflow that minimizes errata risk:

• Request transcript review on the record at the close of the deposition.
• Calendar the 30-day deadline immediately.
• Read the transcript carefully with the deponent, identifying every potential correction.
• Distinguish between corrections that fix actual errors (transcription, ambiguity, memory issues supported by records) and corrections that reflect post-deposition reconsideration. Only the former should make the errata sheet.
• For each correction, draft a specific reason that explains the basis. Conclusory reasons ("witness misspoke") are weaker than specific reasons ("witness identified document by its file name; document is correctly identified as [name] per page 14 of Exhibit 7").
• Submit the errata before any dispositive motion is filed where possible.

For the deponent's side, the discipline is to use errata for what it was designed for and to recognize that material substantive changes will be contested.

Frequently Asked Questions

Does the original deposition testimony remain in the record after errata?

In nearly all jurisdictions, yes. The original testimony is preserved regardless of the errata. The errata supplements the record; it does not strike the original. This means the original testimony remains available for impeachment at trial and as substantive evidence in most contexts.

Can a party file an errata for a deposition the party did not take?

Only the deponent has the right to submit errata. A party cannot correct another party's deponent's testimony through errata. Errors believed to exist in another party's deposition can be addressed at trial through cross-examination or through other evidentiary mechanisms, but not through Rule 30(e).

What if the 30-day window has passed?

In most circuits, late errata are simply ineffective. Some courts have permitted late errata in extraordinary circumstances — illness, attorney withdrawal, transcript not actually delivered — but the default rule is strict compliance.

Are errata sheets discoverable?

Once filed, errata sheets are typically part of the deposition record and discoverable as part of it. Drafts of errata sheets, attorney communications about errata, and the underlying preparation are generally protected as work product, though the work-product protection may be limited where errata is challenged as sham.

Closing

The errata sheet is a procedural tool whose substantive scope has narrowed considerably over the past two decades. The permissive approach that once treated "form or substance" as license for tactical revision has been substantially constrained by the Hambleton line and the sham-affidavit doctrine.

For PI practitioners, the working discipline is to treat errata as a mechanism for genuine corrections — transcription errors, clarifications, and record-supported revisions — and to recognize that substantive changes contradicting earlier testimony will be contested, often successfully. The depositions that produce strong, defensible records are those in which the testimony was given carefully the first time. Errata is a backstop, not a primary tool.
