Using WhatsApp Messages as Court Evidence

The Problem: Raw .txt Files Are Rejected in Court

When a dispute reaches court, judges and lawyers expect professionally formatted, paginated documents with clear provenance. A raw WhatsApp .txt export, or worse, a folder of screenshots, is almost always rejected. It lacks page numbers, has no integrity verification, and is trivially easy to edit.

Screenshots can be cropped, edited, or faked
Raw .txt files have no pagination or exhibit numbering
No chain-of-custody documentation
Personal data of uninvolved parties may need to be redacted
Judges expect a forensically documented exhibit

How WaChat to PDF Produces Court-Ready Exhibits

Export from WhatsApp

Use WhatsApp's built-in export feature to download a .zip file including all media. This preserves the original metadata and timestamps.

Upload to WaChat to PDF

Drop the .zip file into WaChat to PDF. The parser reads every message, timestamp, and attached media file with 100% accuracy.

Enable Pro Features

Activate Bates numbering (sequential page stamps), PII redaction (auto-removes phone numbers, emails, SSNs), and SHA-256 integrity hash generation.

Download and Submit

Your PDF arrives as a court-standard exhibit: paginated, timestamped on every page, with an integrity seal that proves the document has not been altered.

Legal Context and Disclaimer

Digital evidence rules under FRE 901 (US), CPR Part 31 (UK), and equivalent frameworks require authentication. WaChat to PDF's integrity seal and metadata preservation satisfy these requirements in the vast majority of civil proceedings. Always consult your solicitor or attorney for advice specific to your jurisdiction.

Frequently Asked Questions

Are WhatsApp messages legally admissible as evidence?

Yes, in most jurisdictions, digital messages are admissible provided they are authenticated and unaltered. WaChat to PDF's SHA-256 hash and Bates numbering help establish that authentication.

Do I need to disclose the other person's messages?

Generally yes. You are typically required to disclose all relevant communications, not just the ones that support your case. Your legal team will advise on disclosure obligations.

What if the other party claims the messages were edited?

The SHA-256 integrity hash in your WaChat to PDF PDF can be verified against the original export file to prove no content was altered.
