WhatsApp Chats as Evidence in Indian Courts (2026)

India is WhatsApp's largest market, and Indian courts see WhatsApp evidence daily — matrimonial disputes, cheque-bounce cases, property disagreements, employment matters, and criminal trials. The chats are usable, but Indian law attaches a specific procedural condition that trips up more litigants than any question of relevance: the electronic-evidence certificate. This guide covers the legal framework as it stands after the Bharatiya Sakshya Adhiniyam, 2023, the rulings that shape practice, and the concrete steps to get a chat from a phone into a form a court will accept.

The Short Answer

WhatsApp chats are admissible in Indian courts as electronic records. If you produce them as a printout or PDF — which is almost always how it is done — they are secondary evidence and must be accompanied by a certificate: Section 65B(4) of the Indian Evidence Act for older matters, Section 63(4) of the BSA for matters governed by the new code in force since 1 July 2024. The Supreme Court held in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) that this certificate is mandatory. Without it, courts refuse the chats regardless of what they show. With it — plus sensible preservation and a clean, complete export — WhatsApp evidence is routinely admitted and acted upon.

The Legal Framework

Electronic records are documents

Indian evidence law treats electronic records as documentary evidence. A WhatsApp conversation stored on a phone is an electronic record; a printout or PDF generated from it is computer output. The law's central concern is reliability: how does the court know the output faithfully reflects what the device holds, and that nobody edited it along the way?

The certificate requirement

The answer is the statutory certificate. Under Section 65B(4) of the Evidence Act — and now Section 63(4) BSA — the party producing electronic output must file a certificate identifying the record, describing the device and the manner of production, and confirming the device was operating properly. The BSA's prescribed format goes further: it requires disclosure of a hash value of the record and contemplates certification by an expert alongside the person in charge of the device. The full field-by-field breakdown is in our dedicated certificate guide.

The rulings that define practice

• Anvar P.V. v. P.K. Basheer (2014) — the Supreme Court held secondary electronic evidence is inadmissible without the 65B certificate, overruling earlier practice that let it in under general secondary-evidence rules.
• Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) — a three-judge bench confirmed the certificate is a mandatory condition precedent, clarified it is unnecessary when the original device itself is produced, and allowed courts to direct production of the certificate at the appropriate stage.
• Post-2020 practice on WhatsApp specifically — courts including the Supreme Court have observed that WhatsApp messages without proper certification carry no evidentiary value, and forwarded messages are treated with particular scepticism because the forwarding chain breaks the link to an original author.

What Courts Scrutinise in WhatsApp Evidence

• Completeness — a full conversation carries far more weight than isolated messages. Selective extracts invite the argument that context was suppressed.
• Authorship — the number and account must be tied to the person. Group chats need care: you must show who sent which message, not just that it appeared in the group.
• Integrity — has the record been altered? This is exactly what the BSA's hash requirement targets, and why a hash-verified PDF is now the sensible default format.
• Chain of custody — who exported the chat, when, from which device, and what happened to the file afterwards.
• Blue ticks and delivery — read receipts can support knowledge or receipt of a message, but courts treat them as circumstantial, not conclusive; settings can disable them.

Step-by-Step: Preparing WhatsApp Evidence for an Indian Court

Step 1 — Export the complete chat

On iPhone: open the chat, tap the contact or group name, scroll down, tap Export Chat, choose Attach Media if images or voice notes matter, and save via the share sheet to Files. On Android: open the chat, tap the three-dot menu, More, Export chat, choose with or without media, and save the .zip or .txt file directly. Export the entire conversation for the relevant period and keep the original export file untouched — it is your reference copy if integrity is contested.

Step 2 — Convert to a paginated PDF with a SHA-256 hash

A raw .txt export is editable and hard to read. Converting it into a formatted PDF restores the conversation layout with senders and timestamps, adds page numbers a judge can cite, and generates a SHA-256 hash you can quote in the Section 63 certificate — the same hash the BSA Schedule expects to see disclosed. The certificate, the PDF, and the hash together form a coherent package: the certificate says what the record is, the PDF is the record, the hash proves it has not changed.

Step 3 — Prepare the certificate

The person who controls the device and performed the export signs the certificate, identifying the phone, the export process, the working-condition statements, and the hash. In contested matters an expert's co-certification of the hash and extraction procedure adds weight and is contemplated by the BSA Schedule. Our separate guide walks through every field.

Step 4 — Preserve the device

Keep the phone with the original chat intact until the matter concludes. If admissibility is fought, producing the original device converts your evidence from secondary to primary and sidesteps the certificate battle entirely — Arjun Panditrao expressly preserves that route. Deleting the app, wiping the phone, or losing it mid-litigation hands the other side an integrity argument.

Common Mistakes in Indian Proceedings

• No certificate — the single most common and most fatal error since Anvar and Arjun Panditrao.
• Screenshots instead of exports — fragments with no metadata, no pagination, and no integrity trail.
• Editing the export 'to remove irrelevant messages' — any modification changes the hash and can be characterised as tampering; let your advocate handle relevance through submissions.
• Relying on forwarded chats — the forwarding chain severs the connection to the original record.
• Producing chats obtained from someone else's phone without lawful access — creates admissibility and legal-exposure problems simultaneously.
• Ignoring group-chat authorship — establish who sent each relied-upon message, not merely that the group contains it.

Key Takeaways

• WhatsApp chats are admissible in Indian courts, but secondary production requires the statutory certificate — 65B historically, Section 63(4) BSA since July 2024.
• Arjun Panditrao (2020) made the certificate non-negotiable; producing the original device is the only alternative.
• The BSA adds a hash-disclosure requirement — generate a SHA-256 hash when you prepare the PDF.
• Export complete conversations, preserve the original file and device, never edit.
• Forwarded messages and screenshots are the weakest formats; a certified, hash-verified PDF of the full export is the strongest.
