Are WhatsApp messages admissible in court?

Often yes. None of the seven countries below bars a message just because it came through WhatsApp. You have to be able to show who sent it and that nothing has been changed. Getting a message accepted also doesn’t mean the court will believe it, because the judge still decides how much it proves.

This is general information and it isn’t legal advice. The rules depend on your country, your court and the type of case, so if a lot is at stake, ask a lawyer. If your question is about screenshots or whether a message can bind you to a deal, we cover those separately.

What every court wants to know

The wording changes from country to country, but the questions are much the same:

Who sent it. A phone number helps, and so do details in the messages that only that person would know.
Whether it has been changed. This covers editing, and also leaving out messages that change the meaning.
Whether it matters to the case. A real message about something else won’t help you.

Courts accept many kinds of proof for the first two questions. Your own evidence as someone in the chat is often a good start.

The rules by country

United States

Under federal Rule 901, you need evidence “sufficient to support a finding that the item is what the proponent claims it is”. A person who took part in the chat can give that evidence, and the contents of the messages can help too.

In United States v. Espanola (7th Circuit, 2026), the appeal court said a WhatsApp log could be authenticated by what it said and by matching bank records, leaving aside the fact that the defendant had produced it. No one from the chat had to testify. The court said: “The authenticity requirement does not demand certainty.”

An accurate printout counts as an original under Rule 1001. State courts have their own rules, so check the rules where your case is.

England and Wales

In civil cases, a copy of a document can be used if it’s “authenticated in such manner as the court may approve”, under section 8 of the Civil Evidence Act 1995.

A document you disclose is treated as genuine unless the other side serves a notice asking you to prove it, under rule 32.19. In Skywind Holdings v Wilson (2025), one side denied that WhatsApp messages were genuine and later served that kind of notice, and the judge said authenticity would be decided at trial. Criminal cases follow different rules.

India

India is the only country on this list where we found a certificate requirement. Section 63 of the Bharatiya Sakshya Adhiniyam replaced section 65B of the old Evidence Act from 1 July 2024. It requires a certificate each time an electronic record is submitted, signed by the person in charge of the device and an expert. Cases already under way on that date stay under the old Act.

The courts take this seriously:

In Arjun Panditrao Khotkar (2020), the Supreme Court said the certificate is a condition of admissibility and that oral evidence can’t replace it. It also said no certificate is needed if the owner produces the phone in the witness box.
In Jyoti Rani v Nishant Kumar (2026), the Patna High Court called WhatsApp messages without a certificate “wholly inadmissible”.
In a 2026 order, the Andhra Pradesh High Court said a person may certify messages on their own phone, if the certificate meets the law’s requirements.

South Africa

Section 15 of the ECT Act says the rules of evidence “must not be applied so as to deny the admissibility of a data message” just because it’s electronic. How much weight it gets depends on how reliable it is and how the sender was identified.

In Ackerman v Amaning (2026), the Supreme Court of Appeal said a WhatsApp message “constitutes a document and may be tendered as documentary evidence”. No IT expert was needed there. The person who received the messages gave evidence and had the phone in court. Acceptance still isn’t automatic. S v Brown said the Act doesn’t make a data message admissible “without further ado”, although the phone photos in that case were admitted.

Canada

Section 31.1 of the Canada Evidence Act asks for “evidence capable of supporting a finding” that the document is what it claims to be. The Ontario Court of Appeal says this threshold is low. It has also warned that judges “need to be very careful” with this kind of evidence. Each province also has its own Act, such as Ontario’s.

Singapore

The Evidence Act 1893 covers records stored or sent electronically. Unless there’s evidence raising doubt, the courts presume that a device that normally works properly communicated a record accurately, as explained in Baizanis v Snap Innovations. That presumption doesn’t reach the words themselves: “there is no presumption as to the truth of the content of the record”, the Court of Appeal said in GIL v Public Prosecutor.

Australia

The Evidence Act 1995 applies in federal courts, and most states have a similar Act. South Australia and Queensland don’t. A document produced by a device can prove what the record says (section 48). A message is presumed to come from the person it appears to come from, unless there’s evidence raising doubt (section 161).

What to do before you need it

Keep the phone and the chat. In England, a court may treat a copy as worthless if you could easily have produced the original and didn’t.
Export the whole chat, with media. Keep the file exactly as WhatsApp made it. Our guide to preserving messages as evidence covers each step.
Write down who is who. Note each person’s full name and phone number.
Make a copy people can read. A judge won’t want to scroll through your phone or a raw text file.
Ask what your court needs. Local rules may require a certificate or a particular format.

For step 4, you can open your export on Chatonfile.com and read it for free on your device. If you need a copy on paper, you can order a dated PDF with every message numbered and each voice note written out. It’s a readable copy of your export. It isn’t certified, and each court decides what it accepts.
