WhatsApp evidence, start to finish.
Everything you need to turn a WhatsApp conversation into a structured, admissible record — for mediation, small claims, business disputes, or your own clarity before talking to a lawyer.
In this guide
This guide is informational, not legal advice. Admissibility depends on jurisdiction, case type, and the facts of your dispute. When the stakes are high, speak to a lawyer in your jurisdiction.
What counts as WhatsApp evidence
A WhatsApp conversation can support claims about what was agreed, when, by whom, and on what terms. In civil and commercial disputes, the most useful evidence is the full exported chat — not screenshots.
The export file contains the raw text log, timestamps, sender identifiers, and optionally media (images, voice notes, videos). Together, these create a coherent record that is far harder to challenge than isolated screenshots.
ThreadRecap adds a second layer: an analysis that extracts the timeline, decisions, verbal agreements (from transcribed voice notes), and unresolved points. You get two artifacts — the raw chat and the structured report — that tell the same story.
Is a WhatsApp export admissible
In most jurisdictions that accept digital evidence, a WhatsApp chat can be submitted — provided it is authentic, complete, and the chain of custody is clear. Authenticity usually relies on metadata (timestamps, phone numbers, device identifiers) and an unbroken narrative (no edits, no gaps).
Screenshots are generally weaker because they can be cropped, edited, or taken out of order. A full export file, backed by a structured analysis that references specific timestamps and quotes, is significantly harder to dispute.
How to prepare your evidence
- 1
Export the full conversation
Open the WhatsApp chat → tap the contact or group name → scroll to Export Chat → choose Include Media when voice notes or images matter. Send the .zip to yourself.
- 2
Upload to ThreadRecap
Drop the .zip into ThreadRecap. The file is unzipped in your browser — photos and videos never leave your device. Only the parsed text (and audio, if you opt in) is sent to the AI.
- 3
Pick the dispute goal
Choose the Dispute Summary, Business Partner Dispute, Small Claims, or custom goal that matches your case. Each one emphasizes different elements (timeline, commitments, contradictions).
- 4
Get the structured report
You receive a chronological timeline, key agreements with quoted messages, action items with owners, and unresolved points. Voice notes are transcribed and anchored to timestamps.
- 5
Save both artifacts
Keep the original .zip export (raw source) and the ThreadRecap report (structured narrative). If you go to a lawyer or mediator, bring both.
Common mistakes to avoid
Relying on screenshots
Screenshots can be cropped, edited, or selectively shared. A full export is harder to challenge and more likely to survive scrutiny.
Cherry-picking messages
Selecting only favorable messages breaks the narrative. Judges and mediators are trained to notice — present the full conversation, then direct attention to the key passages.
Ignoring voice notes
Verbal agreements spoken in voice messages carry weight but are invisible unless transcribed. ThreadRecap transcribes voice notes automatically and places them in the timeline.
Missing timestamps
An unanchored quote is weak. Every claim should be tied to a specific date and time visible in the export.
Waiting too long to export
Phones break, accounts get suspended, and chats can be cleared. Export early — you can always re-analyze later.
By dispute type
Five specialized reports, built for the most common disputes documented in WhatsApp.
Business partner disputes
Equity, revenue split, responsibilities, exit terms.
Small claims court
Unpaid work, service disputes, deposit issues.
Landlord and tenant
Deposits, repairs, lease terms, move-out disputes.
Workplace documentation
HR records, harassment, policy discussions, employee agreements.
Freelancer and client
Scope creep, late payment, deliverable disputes.
Rules by jurisdiction
A brief overview — always check with a lawyer in your country.
Brazil
WhatsApp conversations are widely accepted in civil, labor, and consumer disputes when authenticity can be shown (metadata, notarized acts, or ata notarial in high-stakes cases).
United Kingdom
Messaging evidence is admissible in civil courts under CPR rules when the party can show authenticity and continuity. Full exports outperform screenshots.
United States
Federal Rules of Evidence (FRE 901, 902) allow digital evidence when authenticated. Practice varies by state — check local rules for small claims.
Portugal
WhatsApp messages are accepted as documentary evidence in civil and labor cases. Clearer chain of custody strengthens weight at trial.
Presenting your evidence
Lead with the structured report. It gives the reader — whether a mediator, lawyer, or judge — the narrative: what was agreed, when, and by whom.
Reference the raw export for every key claim. A sentence like "on March 5th at 18:45, the partner agreed to a 60/40 split via voice note (transcript in export)" is stronger than a summary without anchors.
Keep a backup of the original .zip and the report PDF in separate locations. If the opposing party challenges authenticity, you can produce the source file.
