In this article, the authors analyzed the problem of using correspondence on social networks to provide it as evidence in court proceedings in the context of fulfilling obligations under the concluded contract. The study of scientific views and judicial practice has shown different points of view on the definition of signs of compliance with the contract in electronic interaction, sometimes contradicting each other. The problems and difficulties that have to be faced when confirming facts using correspondence on social networks as evidence have been identified. As a result, the authors concluded that it is necessary to amend the civil legislation of the Russian Federation in order to more accurately solve this problem in the courts, and also proposed recommendations for consolidating these legal norms.
