Messenger Chats as Court Evidence

The Supreme Court’s Position

The Supreme Court of Russia confirmed: negotiations conducted via messaging apps (WhatsApp, Telegram, and others) may be recognised as a written agreement when three conditions are met:

  1. The parties are identifiable — it is clear from the chat who is negotiating (name, position, organisation, phone number, or other identifying information).
  2. The subject matter is defined — what exactly is being bought, sold, or performed, and in what scope.
  3. The terms are specific — price, deadline, and key parameters.

The legal basis is Article 434 of the Civil Code: a contract may be concluded “by exchanging documents” through any communication channel, including electronic ones.

What This Means in Practice

If you agreed with a contractor in WhatsApp to carry out renovation work for 300,000 rubles, discussed timelines and the list of works — this may be recognised as a contract. If the contractor fails to perform or performs inadequately, you may go to court with a printout of the chat as evidence of the existence of the agreement and its terms.

The Main Problem: Preservation

The Supreme Court specifically noted the storage risks associated with such correspondence. Unlike a paper contract:

  • the messenger may be hacked,
  • the account may be blocked or deleted,
  • the chat history may be cleared by the other party,
  • the app may be deleted from the device,
  • messages may be edited (in some messengers).

All of this creates a risk of losing the evidentiary record at the worst possible moment.

How to Properly Preserve Messenger Agreements

Notarial inspection of the chat. A notary inspects the correspondence on the device and draws up a record documenting its contents. This document has the force of notarially certified evidence and cannot be challenged.

Screenshots with metadata. For court use, a printout showing dates, times, and participant identifiers is acceptable. The clearer the identifiers — the better.

Follow up with a paper document. Best practice: after messenger negotiations, draw up and sign a brief paper agreement (an offer and acceptance, or a letter of intent). The messenger chat is the negotiation history; the paper document is the insurance.

Never delete the chat if there is any risk of a dispute. Deleting correspondence by a party who later files a claim may be treated as destruction of evidence.

Who This Matters Most For

Messenger chats as evidence are critically important for:

  • freelancers and contractors — if no contract was formalised, the chat may be the only evidence of the terms agreed,
  • entrepreneurs who negotiate informally,
  • consumers who arranged work or a purchase via a chat with a tradesperson or a shop,
  • employees who received a verbal or written promise from an employer via a messaging app.
