Are WhatsApp chats valid evidence?

Short answer: yes, as an electronic record, and the question has not seriously been whether for some years. The real questions are how it is proved, and what it is worth once it is in.

The starting point

A WhatsApp conversation is an electronic record, and Indian evidence law has for two decades declined to treat electronic records as second-class merely because they are electronic. The Bharatiya Sakshya Adhiniyam, 2023, which replaced the Indian Evidence Act, 1872 with effect from 1 July 2024, continues that position and expressly contemplates information held in semiconductor memory and on communication devices — which closes off the old argument about whether a phone was a “computer”.

So admissibility in the abstract is not the fight. The fight is about the route by which the record reaches the court.

Primary and secondary

If the device itself is produced and the conversation is shown on it, that is the record. In practice nobody does this: phones are needed, cases run for years, and a court has better uses for its time. So the conversation is produced in secondary form — an export, a transcript, a printout — and Section 63 governs, which brings in the certificate under Section 63(4).

That certificate is not a formality. In Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) the Supreme Court, dealing with the predecessor provision, held that it is mandatory where secondary electronic evidence is relied upon. Section 63(4) now prescribes the form as well as requiring it: a Schedule in two parts, with the hash value of the record stated. The certificate format sets that out in full.

Three different questions

Most confusion about chat evidence comes from running these together:

• Admissibility. May the court receive this at all? For a certified electronic record, ordinarily yes.
• Proof. Is this record what it says it is — a genuine export of a real conversation on a real device? This is where the certificate, the hash and the account of production do their work.
• Weight. Assuming it is genuine, what does it establish? A conversation is evidence of what was said, which is not the same as evidence that what was said is true, and is not evidence at all of who was holding the other phone.

An exhibit can clear the first, survive the second and still be worth very little on the third. That is not a failure of the document; it is the document being read correctly.

What a chat is generally good for

• Admissions. A party’s own message acknowledging a debt, a receipt, a fact or a course of dealing is often the most valuable line in a transcript.
• Contemporaneous record. Messages written at the time, before anyone was in dispute, carry a weight that later recollection does not.
• Corroboration. A chat that lines up with a bank entry, a delivery note or a call record is doing something a chat alone cannot.
• Establishing that a communication happened at all — a demand, a notice, a refusal — on a date.

What it is routinely asked to do and cannot

• Prove who typed it. A display name is what the exporting phone had saved. Where authorship is genuinely in issue, corroboration outside the chat does the work.
• Prove the truth of its contents. A message saying “I paid you on Tuesday” is evidence that the statement was made.
• Show what was deleted. An export is a snapshot. See deleted messages and the limits of an export.
• Speak for a period it does not cover. A four-message extract from a two-year exchange is an argument about context waiting to happen.

The objection you should expect

The standing objection to every chat exhibit, and to every product in this category, is that a text file can be typed. A hash fixes a file from the moment it was computed; it does not show the file came out of WhatsApp rather than out of an editor. That gap is real. It can be narrowed — a genuine export carries structural features an edited transcript loses, and those can be tested and reported — but it is not closed by software, and it is the reason Part B exists and the reason a doubting court may want the handset.

An exhibit that states this on its face is harder to attack than one that quietly implies more than it can carry. The challenge checklist is the same list read from the other side.
