" Electronic data refers to information formed or stored in electronic media by means of e-mail, electronic data exchange, online chat records, blogs, Weibo, SMS, electronic signature and domain name. To sum up, chat records belong to one kind of electronic data. In order for the court to recognize and support WeChat as evidence, the following proofs must be completed: (1) It must be confirmed that the users of WeChat are both parties. The parties submit WeChat evidence to the court, but it cannot prove that the party using WeChat is a party to this case, which does not meet the subject conditions in principle. (2) Ensure the legality of ways and means to obtain WeChat chat records. Obtaining evidence by illegal means such as illegal search and illegal seizure cannot be supported by the court. (3) True and complete WeChat evidence must be provided, the relevance between WeChat evidence and other evidence must be guaranteed, and a complete evidence chain must be formed. In litigation cases, if you want to get the judge's approval and support for the evidence, you must ensure that the evidence is true, legal and relevant.
