Message excerpts, context, and the rule of completeness

Preserve the full thread before choosing an excerpt

An excerpt is a presentation choice, not a preservation method. Keep the complete available conversation first. Then select the smallest continuous range that fairly answers the issue, with enough messages before and after it to explain references, replies, tone, and timing.

Single-message screenshots are particularly easy to misunderstand. “Yes” may answer a different question than the caption suggests. A joke may depend on an earlier exchange. A later correction may change an apparent admission. Replies and quoted messages should remain linked to their source where possible.

FRE 106 addresses misleading incompleteness

Federal Rule of Evidence 106 says that when a party introduces all or part of a statement, an adverse party may require introduction, at that time, of another part or another statement that “in fairness ought to be considered at the same time.”

The 2023 amendment matters for chats. The former text referred to a writing or recorded statement. The current rule covers statements generally, including oral and unrecorded statements according to the committee note. It also says the completing statement is admissible over a hearsay objection when fairness requires simultaneous consideration.

This does not mean every message in an account must be offered. The question is whether omitted material is needed to correct a misleading impression. Other evidence rules still apply, and state rules may differ.

Build an honest focused excerpt

Define the source at the top: platform, conversation, participants, date range, export date, and selection method. Keep messages in source order. Use full dates at each day change and stable sequence numbers that map back to the complete export.

Show every discontinuity. A useful marker is:

[Messages 148–171 omitted: 24 messages about unrelated scheduling. Preserved in full export.]

Do not use an ellipsis where it could be mistaken for text typed by a participant. Do not renumber selected messages to conceal gaps. If pages were removed, say which pages. If a search term produced the excerpt, record the term and whether variants were checked.

Attach or offer the complete relevant export when procedure permits. A long record can be separated into a full reference bundle and a shorter hearing extract, both using the same page or message identifiers.

A compact excerpt can use a layout like this:

Message	Source date and time	Sender	Content
0146	Mar. 6, 2026, 9:12 a.m.	A	Can you bring the documents today?
0147	Mar. 6, 2026, 9:14 a.m.	B	Yes, after the appointment.
—	—	—	[Messages 0148–0171 omitted: 24 scheduling messages; retained in full export]
0172	Mar. 7, 2026, 8:03 a.m.	A	I received the signed copy.

The marker occupies its own row. It cannot be mistaken for participant text. The original numbers reveal the gap and map every displayed item back to the complete export. Use the source’s date and time as recorded, and put any normalized time in a separate field.

Choose boundaries by meaning, not by page count

Start before the disputed message far enough to identify the topic and question being answered. End after any immediate response, clarification, correction, or change of position. Include quoted-message targets when a reply would otherwise float without context.

Date boundaries alone may be misleading. A conversation can pause for days and resume with “as I said above.” Search backward for the reference. Group chats may require membership notices or sender identifiers. Attachments need their captions and nearby message, not just a thumbnail.

Write the selection rule before selecting. Examples include “all messages between 8:00 a.m. and noon on March 6,” “messages 120–205,” or “the complete exchange beginning with the repair request and ending with the landlord’s response.” A reproducible boundary is easier to defend than “the important messages.”

Search results are leads, not a self-explanatory excerpt. Search may miss spelling variants, images, voice notes, edited text, and quoted replies. If search terms were used, preserve the query and review neighboring results in source order.

Redact visibly and consistently

Privacy redaction should conceal only what needs protection. Replace content with a label such as [phone number redacted], [minor’s name redacted], or [unrelated medical detail redacted]. The label tells the reader that text existed and why it is absent.

Keep an unredacted preservation copy under appropriate access controls. Redact a derivative, then inspect the final PDF to ensure hidden text, comments, layers, and metadata do not reveal the information. A black rectangle placed over selectable text may not remove it.

For US federal filings, FRCP 5.2 generally permits only the last four digits of a Social Security or taxpayer-identification number and financial account number, the year of birth, and a minor’s initials. The rule has exceptions and allows protective orders or filings under seal. Local rules and case-specific orders can add requirements.

In England and Wales, Practice Direction 5A directs parties considering court-file access to consider confidential or private information and whether an application restricting access is needed. Do not assume filing makes sensitive third-party chat content private. Check the relevant court and case directions before lodging a bundle.

Build a redaction log that does not repeat the protected value. It can list page or message number, category, reason, person who applied it, and date. Use labels consistently. [REDACTED] is less useful than [financial account number redacted] when the category can safely be named.

Redact in the final delivery format with a tool that removes the underlying content. Then search, copy and paste, inspect comments and layers, and check document metadata. Flattening a black box over text may only hide it visually. Keep the unredacted source access-controlled and separate from the version intended for filing.

FRCP 5.2’s default partial-redaction categories are precise. Federal filings generally use the last four digits of Social Security and taxpayer-identification numbers, the year of birth, a minor’s initials, and the last four digits of a financial-account number. The rule contains exceptions and procedures for protective orders and sealed filings. Do not expand or narrow those directions from memory; check the current rule and local requirements.

Keep context without over-sharing

Completeness and privacy can coexist. Include messages that explain the disputed passage, while redacting irrelevant identifiers and intimate third-party material. Explain the selection and retain the underlying record so the choice can be reviewed.

A short methodology note is useful: “Pages 1–6 reproduce messages 120–205 in source order. Messages 147–171 are omitted as unrelated scheduling and marked in place. Names of two minors are replaced with initials. The complete unredacted export is retained.”

That is more credible than saying “irrelevant messages removed.” It identifies what happened without arguing the merits.

Separate selection from interpretation

An excerpt should reproduce the record before it argues about it. Keep editorial summaries, allegations, and conclusions outside the transcript rows. If a declaration says what a phrase meant, let the declaration cite the stable message number. Do not rewrite the message into the interpretation.

Translation requires the same separation. Preserve the source-language text, identify the translator and method where required, and place a translation in a clearly labeled adjacent column or separate document. A machine translation should be identified as such and checked before consequential use. Do not replace the original words.

Likewise, a corrected OCR reading belongs in an overlay or corrections log linked to the source screenshot. Show enough of the source image for the correction to be reviewed. Never silently replace low-confidence text in the preserved transcript.

Review the excerpt for both favorable and unfavorable context

Read at least one screen or several messages before and after every selected passage. Check for sarcasm, retractions, conditional language, quoted material, and a later answer to an earlier question. Verify who was in the group at that time. Confirm that replies point to the correct message.

Ask a second person, where privacy and authority permit, to follow each excerpt reference back to the full source. They should be able to find the same message, confirm the text, and identify every gap. Record discrepancies and correct the derivative, not the source.

Create a final reconciliation table with the excerpt’s first and last message number, omitted ranges, redactions, attachment count, and corresponding full-export pages. That table often reveals a missing transition before filing does.

Use stable references

Give every message a sequence number and every exhibit page a page number or Bates identifier. Quotes in a statement can then cite SMITH-000123, message 174. If the excerpt changes, the reference to the preserved full export remains stable.

Never silently sort by timestamp, merge conversations, rewrite spelling, or replace a sender label. Corrections and display-name choices belong in a disclosed overlay or note. The source remains unchanged.

Version the excerpt when boundaries or redactions change. A filename such as messages-excerpt-v2-redacted.pdf is clearer than overwriting final.pdf. Record its source export, creation date, page count, message ranges, and hash. Citations should use stable message or Bates identifiers rather than a PDF viewer’s page count alone.

In England and Wales, the assembled court bundle may impose its own continuous page numbers. Keep the message identifier as well as the bundle page. An index can then say “Message 0172, bundle page 143” without changing the preserved export’s identity. Follow the court’s current bundle directions and any case-specific order.
