Before you file

How this evidence is actually used.

Written to be useful whether or not you use the tool: what the certificate asks for, how to take an export that will stand up, and how chat evidence is treated in Indian proceedings.

Start here

The certificate formatThe Schedule to s.63(4) set out in full — Part A, Part B and the particulars of the record and the device, entry by entry.
Exporting for courtAndroid and iPhone, with and without media, and how to move the file without changing its hash.
WhatsApp chat to PDFTurning the file WhatsApp gives you into a document a court can read — and why the PDF is not the thing the certificate describes.
Are chats valid evidence?Admissibility, proof and weight are three different questions, and most confusion comes from running them together.
Filing the exhibitWhat goes on the file, when the certificate must be filed, and what has to be served on the other side.
From s.65B to s.63What the Bharatiya Sakshya Adhiniyam changed for electronic evidence, and what carried over.

By proceeding

DivorceCruelty, the date of separation, and the problem with messages taken off a spouse’s phone.
498AFiled by both sides, for opposite reasons — and why completeness decides which one it helps.
Cheque bounceThe transaction behind the cheque, admissions of liability, and the security-cheque defence.
MaintenanceIncome, concealed earnings and standard of living, read against the affidavit of disclosure.
Domestic violenceVerbal, emotional and economic abuse — the forms that leave no record except a conversation.
Commercial disputesWhere the conversation is not corroboration of the contract but frequently is the contract.

What you receive

Eight parts, in the order the Schedule sets them out.

CoverThe fingerprint block, the conversation at a glance, the chain of production, and what the record does and does not establish.
Part AThe deponent’s certificate under s.63(4), pre-filled from your particulars, with the SHA-256 disclosed.
Part BThe expert’s certificate, with the twelve particulars the Schedule calls for already computed.
Schedules I & IISet out as the statute lays them out.
Annexure AThe full transcript, laid out as WhatsApp shows it, every message attributed and numbered for citation.
Annexure BThe media itself — images one to a page, documents rendered, each file hashed separately and reconciled against the transcript.
Annexure CThe integrity checks: eleven tests of the export against structure WhatsApp itself writes, and what each one found.
OriginalsOn the media tier, every attachment delivered alongside the exhibit with a manifest of their hashes.

Section63 prepares the form of a certificate and records the hash of the file it receives. It does not verify the truth of a conversation, the identity of the participants, or the declaration you sign — and it is not legal advice.

Why the hash matters

In Pune Bar Association v. Union of India (2026) the Supreme Court upheld the Section 63(4) certificate and held that the hash value of electronic data “is synonymous with an electronic fingerprint.” Part A of the Schedule requires it to be disclosed. Every exhibit issued here states it.

A hash fixes the file as it was received. On its own it does not show the file came out of WhatsApp rather than a text editor — which is the objection every product in this category invites. So Annexure C sets out eleven checks against structure the application itself writes and an edited transcript loses, and reports what each one found. They corroborate; they do not decide. Admissibility is for the court.
