Can WeChat chat records be used as evidence of cheating?

Theoretically, you can, but you need to provide original evidence that can verify the identity of both parties before you can use it as evidence.

The Civil Procedure Law of People's Republic of China (PRC), which was implemented on 20 12, made it clear that electronic data is the legal type of evidence. The judicial interpretation of the Civil Procedure Law further clarifies that audio-visual materials include audio-visual materials and video materials, and electronic data refers to information formed or stored in electronic media by means of e-mail, electronic data exchange, online chat records, blogs, Weibo, mobile phone short messages, electronic signatures and domain names. The information on WeChat platform exists in the form of electronic data, which belongs to the category of evidence stipulated by the Civil Procedure Law.
