Using WeChat Chat Records as Evidence in Chinese Courts: A Practical Guide

WeChat has become an integral part of business and personal communication in China, with billions of messages exchanged daily. As a result, WeChat chat records have become an increasingly important form of evidence in Chinese litigation. Understanding when and how WeChat records can be used as evidence is essential for foreign businesses and individuals involved in legal disputes in China. This article explains the legal requirements and practical considerations for using WeChat evidence in Chinese courts.

The Legal Basis for Electronic Evidence

Under Article 66 of the Chinese Civil Procedure Law, electronic data (electronic data) is explicitly recognized as a category of evidence along with traditional forms such as documentary evidence, physical evidence, and witness testimony. The Supreme People's Court has issued specific judicial interpretations on the authentication and admissibility of electronic evidence, including detailed guidance on messaging app records.

WeChat chat records, including text messages, voice messages, images, videos, file transfers, and transaction records, are all potentially admissible as electronic evidence. However, the court must be satisfied that the evidence is authentic, complete, and relevant to the disputed facts before it can be admitted and relied upon.

Three Essential Requirements for Admissibility

To successfully introduce WeChat chat records as evidence in Chinese court proceedings, three requirements must be satisfied. First, the party presenting the evidence must provide the original device containing the WeChat records. Screenshots alone, without the ability to access the original messages on the device, may not be sufficient. The original device allows the court or opposing party to verify that the messages have not been altered or fabricated.

Second, the party must prove that the WeChat account used in the communication belongs to the opposing party or the person whose statements are being offered as evidence. This can be accomplished through various means: demonstrating that the phone number associated with the WeChat account belongs to that person, showing that the person's name or photograph appears in the WeChat profile, presenting evidence of previous communications through the same account, or obtaining an admission from the person that they use the account.

Third, the chat records must be complete and unaltered. Selective presentation of only favorable messages while omitting unfavorable context may result in the court excluding the evidence or drawing adverse inferences. The court may inspect the full chat history on the original device to verify that no messages have been deleted or edited.

Practical Preservation Tips

To preserve WeChat chat records for potential use as evidence, users should avoid deleting any messages from the chat history, as deletion raises questions about the completeness and integrity of the remaining records. Regular backups of important chat histories should be made to a second device or cloud storage. Screenshots of key messages should be taken promptly, ideally with visible timestamps and the full conversation context.

For critical business communications, parties should consider confirming important agreements or decisions through a format that is easier to authenticate, such as a signed written contract, a formal email with delivery confirmation, or a WeChat message that includes a clear statement of agreement that can be independently verified.

### Notarization of WeChat Evidence

In practice, many parties choose to notarize their WeChat chat records to enhance their evidentiary value. A notary public can record the process of accessing the WeChat account on the device, navigating to the relevant chat history, and capturing the messages in a legally verifiable manner. Notarized electronic evidence is given greater weight by courts and is more difficult for the opposing party to challenge on authenticity grounds. The notarization process should be completed as soon as possible after the relevant communications occur to minimize any suggestion of evidence tampering.

Mr. Kaihong Xiao of Shenzhen has extensive experience with electronic evidence issues in litigation. He advises clients on proper evidence preservation techniques and represents parties in cases where WeChat chat records and other electronic evidence play a central role. His familiarity with the Supreme People's Court's evidentiary standards and local court practices in Shenzhen allows him to effectively present electronic evidence in support of his clients' claims or defenses.

Common Challenges in WeChat Evidence Authentication

Despite the widespread use of WeChat in Chinese business and personal communications, challenges frequently arise when parties attempt to introduce chat records as evidence. One common issue is the difficulty of proving that a WeChat account belongs to a specific individual. Unlike some messaging platforms that require real-name registration, WeChat accounts can be registered using virtual phone numbers or through linked QQ accounts, making identification more challenging. Courts will consider multiple factors including the account registration information, the profile photo and nickname, the phone number linked to the account, the content of the communications themselves, and corroborating evidence such as bank transfer records or contract documents referencing the same WeChat account.

Another significant challenge is the vulnerability of digital evidence to alteration. Sophisticated parties may attempt to fabricate or selectively edit chat records. Chinese courts have developed various techniques to detect falsified evidence, including examination of the chat record's metadata, comparison with server-side records if available, and cross-examination of witnesses about the authenticity of specific messages. Parties who submit falsified evidence may face adverse evidentiary rulings, monetary sanctions, or referral for criminal prosecution for obstruction of justice.

Best Practices for Businesses Using WeChat

Businesses operating in China should establish clear policies for the use of WeChat in commercial communications. Important contractual terms, price quotations, and transaction confirmations should be documented in formal written agreements whenever possible. When WeChat is used for business communications, employees should be trained to maintain complete chat histories and to avoid deleting messages that may later be relevant to disputes. Companies should implement regular backup procedures for business-related WeChat accounts and consider using WeChat's official business communication tools when available. In litigation contexts, companies should work with legal counsel to ensure that WeChat evidence is properly preserved, documented, and presented in compliance with the Supreme People's Court's evidentiary guidelines to maximize its admissibility and weight.
