WhatsApp Messages Small Claims Court Evidence | ThreadRecap
Small claims court is designed for people to represent themselves. That means you are responsible for presenting your own evidence clearly and concisely. If the key conversations happened on WhatsApp, you need to turn those messages into something a judge can review in minutes, not hours.
This is not legal advice. It is a practical workflow for organizing WhatsApp conversations into structured evidence for small claims proceedings.
Why judges struggle with raw WhatsApp messages
Small claims judges handle dozens of cases per session. They do not have time to scroll through thousands of messages looking for the relevant ones. Common problems:
Screenshots are out of context. A screenshot of "I'll pay you Friday" means nothing without the surrounding conversation.
Printed chat logs are unreadable. Raw _chat.txt files have no structure, no highlights, and no summary.
Voice notes cannot be played in court. If the key agreement was made in a voice note, you need a transcript.
The other party will cherry-pick. If you only show selected messages, the judge sees incomplete evidence.
What works: a complete export with a structured summary that presents the full timeline, highlights key events, and lets the judge see both sides of the conversation.
Why volume alone is not persuasive
A conversation spanning several months can easily run to tens of thousands of messages. Even a shorter dispute thread can produce a _chat.txt file that prints to dozens of pages. Judges in small claims proceedings routinely tell claimants they cannot accept a folder of unstructured printouts. The obligation is on you, as the person presenting the evidence, to distill the relevant facts into a format the court can actually use. That means a structured summary comes before the raw export, not instead of it.
The specific problem with voice notes
Voice notes occupy a frustrating gap in WhatsApp evidence. They are timestamped and tied to a specific sender, which makes them potentially strong evidence, but a court cannot replay an audio file mid-hearing in most small claims settings. If a contractor confirmed a price verbally in a WhatsApp voice note, or a tenant agreed to repair terms in an audio message, that agreement is practically invisible unless it is transcribed. Treating voice notes as a secondary concern is one of the most common mistakes claimants make when preparing WhatsApp chat court evidence.

What you need to prepare
For small claims, you typically need:
A chronological timeline showing key events (agreements, payments, deliveries, disputes)
A summary of the claim with supporting excerpts from the actual conversation
The original export as backup evidence (untouched)
Transcripts of any voice notes that contain relevant terms or agreements
Step 1: Export the WhatsApp conversation
Use WhatsApp's built-in export function. Include media if voice notes contain relevant agreements or commitments.
Important: WhatsApp has export limits. Without media you get up to 40,000 messages. With media, up to 10,000. Make sure your export covers the relevant time period. If not, export without media for more coverage.
Understanding what the export actually contains
When you export a WhatsApp conversation, WhatsApp produces a .zip file. Inside that .zip you will find a _chat.txt file containing every text message in the selected conversation, along with any media attachments you chose to include, such as images, documents, or audio files in .opus or .m4a format. Understanding this structure matters because the _chat.txt file is the foundation of your evidence. Every message in it carries a date, a time, and a sender name exactly as it appeared in the app. That provenance is what gives the export its evidential value. The file is not editable without leaving traces, and submitting it unaltered signals to the court that you are presenting the full record.
If your dispute covers a long period, note that the 40,000-message limit applies when you export without media, and the 10,000-message limit applies when you include media. For most small claims disputes, the relevant window is a matter of weeks or a few months, which fits comfortably within these limits. For longer-running disputes, consider exporting in segments covering distinct phases, such as the agreement phase, the performance phase, and the dispute phase, and label each segment clearly.
Step 2: Preserve the original file
Save the original `.zip` file untouched. Do not rename it, unzip it, or edit anything inside. Email it to yourself or store it in cloud storage so there is a timestamped record.
Work only on a copy. If the other party challenges your evidence, you want the original file with its metadata intact.
Why unaltered exports matter
Editing or deleting messages in a WhatsApp export before submitting it as evidence undermines the credibility of the submission. Even minor changes, such as removing messages you consider irrelevant, can be flagged by the other party as selective editing. Courts pay attention to whether evidence appears complete and consistent. An untouched .zip file with its original timestamp metadata is far harder to challenge than a folder of manually curated screenshots. If the other party claims your export is incomplete, you can point to the original file as proof of what was or was not in the conversation at the time of export.
Create a chronological timeline suitable for small claims court. For each entry include: date, who said what, and the significance (agreement made, payment promised, delivery confirmed, complaint raised, etc.). Only include events relevant to the dispute. Use neutral, factual language throughout. At the end, list: (1) what was agreed and by whom, (2) what was not delivered or disputed, (3) amounts involved if mentioned.
This gives you a 1-3 page timeline that a judge can scan in a few minutes.
What the Custom Prompt option does differently
The standard ThreadRecap summary is well suited to getting an overview of a conversation quickly. The Custom Prompt option, which costs 3 credits, allows you to specify the exact output structure you need. For small claims court evidence preparation, that means you can instruct ThreadRecap to use neutral, factual language, to exclude irrelevant exchanges, and to organize output around the specific legal questions in your case, such as what was agreed, what was delivered, and what money changed hands. The result is a document structured around your claim rather than a general conversation summary. For a judge reviewing twenty cases in a morning session, receiving a two-page structured timeline instead of a stack of printouts makes a concrete difference.
Step 4: Generate a claim summary with evidence
Run a second Custom Prompt with:
Summarize this conversation as if preparing a brief for small claims court. Structure it as: (1) Background — who the parties are and what the arrangement was, (2) Timeline of key events, (3) What went wrong — the breach or dispute, (4) What each party claims, supported by specific messages with dates, (5) Amount in dispute if mentioned, (6) Unresolved questions. Use only facts from the conversation. Do not speculate or interpret intent.
Step 5: Include voice note transcripts
If key agreements were made in voice notes, include media in your export. ThreadRecap transcribes voice notes using Whisper and merges them into the timeline automatically.
This matters in small claims because verbal agreements made via voice note are often the crux of the dispute. A judge cannot replay your WhatsApp voice notes, but they can read a transcript with a timestamp.
How voice note transcription works in practice
ThreadRecap uses OpenAI Whisper to transcribe WhatsApp voice notes in both .opus and .m4a formats, which are the two audio formats WhatsApp uses depending on the device and the age of the recording. Whisper achieves approximately 95% accuracy on clear audio, which is sufficient for a court-ready transcript in the vast majority of cases. Where audio quality is poor, such as recordings made in noisy environments, the transcript will contain markers indicating uncertain sections, which you should review manually before submitting. The transcripts are merged into the conversation timeline with their original timestamps, so a voice note from a specific date appears in the correct position alongside the surrounding text messages. This gives the judge a continuous record rather than a separate document to cross-reference.
Step 6: Prepare your evidence package
Bring to court or submit:
The timeline summary (printed, 1-3 pages)
The claim summary with excerpts (printed, 1-2 pages)
The original export file on a USB drive or available on your phone (backup)
Any supporting documents referenced in the chat (invoices, photos of deliverables, receipts)
Tip: Number your pages and reference the timeline when speaking. "As shown on page 1, on March 12th the defendant agreed to..." is far more effective than scrolling through your phone.
Presenting the package effectively in the hearing
A court-ready evidence package is most effective when you can reference it quickly and consistently during your oral presentation. Print two copies: one for yourself and one for the judge or clerk to review. Highlight the three or four most important messages directly on the printed timeline, not on the raw export. When you speak, refer to specific entries by date and page number rather than by general description. If a voice note transcript is central to your claim, read the relevant passage aloud and point to its place in the timeline. This approach makes the connection between the physical document and your spoken argument immediately clear, which reduces the time the judge needs to spend locating the evidence themselves.
What NOT to do
Do not edit the chat log. Deleting messages or altering the export undermines your credibility.
Do not only show your side. A one-sided selection of messages makes the judge suspicious. The full timeline is more persuasive.
Do not submit thousands of raw messages. The judge will not read them. A structured summary with key excerpts is what works.
Do not ignore voice notes. If they contain agreements, transcribe them. If you skip them, the other party might bring them up.
