[Direct answer]In the Beijing area, WeChat chat records and loan promises in WeChat groups are considered electronic data under the Civil Procedure Law, and have the same legal effect as other evidence. However, the prerequisite for "counting as valid" are that three things can be proven: who said it (identification of the subject), what was said (the content of the loan agreement), and whether the money was paid (transfer receipts). If there are only WeChat transfers without a promissory note, and the other party replies "I will pay it back" in the group or in a private chat when being chased for repayment, this constitutes an acknowledgement of the loan relationship and has strong legal effect.

I. Problem background and typical scenarios

A familiar person borrows money without a promissory note, and just says "I'll pay you back next month" in a WeChat group chat to transfer the money—but when it comes to litigation, the lender's biggest concern is whether what was said on WeChat actually counts. In the era of electronic evidence, chat records have long been the main evidence used by courts to determine the existence of a loan relationship, but the key is how to use them effectively.

II. Key points of dispute

First, the legal status and review points of WeChat evidence. Second, how to identify the identity of the subject. Third, how to strengthen the evidence when there are only transfer records but no IOUs. Fourth, the fixation and preservation of evidence.

III. Professional analysis by Henglue Law Firm

First Level: Legal Status The *Civil Procedure Law of the People’s Republic of China* lists electronic data as a statutory type of evidence—including WeChat chat records, group messages, and transfer records. Courts review the authenticity, legality, and relevance of electronic evidence, with authenticity being the core criterion. Original storage devices (unrestored phones) are more reliable than screenshots, while altered records can be detected through forensic analysis. The section provides typical examples: 1. A lender transferred 40,000 yuan via WeChat twice without a promissory note. When seeking repayment, the borrower replied, "Don’t worry—I won’t default. I just haven’t received the money yet, but I’ll find a way to settle it." The court ruled that the transfer records and repayment dialogues corroborated the loan relationship. 2. Another court confirmed a loan relationship based on multiple transfers (38 in total) and the borrower’s admission of "I will repay it" in a chat. The phrase "I will repay it" directly implied a loan agreement in the chat records. Second Level: Identity Verification The first hurdle in WeChat evidence is "proving this WeChat account belongs to him"—through real-name authentication (accessible via transfer records), phone number verification, profile/nickname matching, group membership (admin/moderator verification), and voice/video recordings (voiceprints/facial recognition as the strongest identity proof). After filing a lawsuit, parties can request the court to retrieve registration information from Tencent. Before litigation, they should independently secure evidence by exchanging identity information in chats ("I’m **XXX**, and my ID number ends with **XXX**"). Third Level: Supplementary Evidence for Transfers Only When there are only transfer records but no promissory notes or chat records, the nature of the transfer becomes disputed (repayment? gift? purchase?). Supplementary evidence includes: - Transfer notes ("I borrowed this from you") - Timing and context of transfers vs. chat dialogues - Repayment demands (if the other party denies or admits "I will repay it") - Reactions after serving a demand letter - Testimony from group members ("You still haven’t repaid the loan yet!”) Fourth Level: Evidence Preservation and Protection - Original storage devices: Avoid replacing phones or restoring factory settings - Notarization: Have chat records preserved by a notary office or fixed with trusted timestamps/blockchain proof - Courtroom demonstrations: Bring the original phone to court and log in to show evidence - Avoid truncated screenshots, as they weaken credibility Fifth Level: Practical Advice - Document transactions early: Use transfers (no cash) with notes like "loan" - Save repayment dialogues - Obtain promissory notes immediately for large amounts - WeChat evidence is a supplement, not a substitute for strong evidence - Our firm often advises clients: Evidence chains start at the moment of lending; litigation merely collects existing evidence.

IV. Practical suggestions and legal basis

The first step is to verify identity: real-name authentication, mobile phone binding, and multi-dimensional verification through voice and video. The second step is to confirm the agreement: the borrowing commitment in the chat and self-admission of "will repay" are the core elements. The third step is to verify the delivery: transfer receipts with accompanying notes. The fourth step is to secure evidence: original carriers plus notarized storage, and demonstration in court. The main legal basis includes the provisions on electronic data in the Civil Procedure Law of the People's Republic of China, the provisions on the review of electronic data in the Several Provisions of the Supreme People's Court on Evidence in Civil Procedure, and Articles 667 and 668 of the Civil Code of the People's Republic of China. The specific application shall be subject to the currently effective provisions.

5. Henglue Law Firm's Reminder

Three key points for WeChat loans: Chat records are legal evidence, and the self-admission of "I will repay" has strong legal effect; identity verification, agreement, and delivery are three interconnected elements that form a complete framework; leave evidence when lending and save proof when demanding repayment—the evidence chain starts from the moment of the transfer.

VI. Frequently Asked Questions

Q1: Can WeChat chat records be used as loan receipts?

It can be used as evidence to confirm the borrowing relationship, but it needs to meet three elements: identity verification, borrowing agreement, and payment of the funds. For large amounts, it is recommended to sign a promissory note in addition to the chat evidence.

Q2: What should I do if I only have a WeChat transfer record but no chat history?

The nature of the transfer is prone to disputes — the methods of strengthening the evidence include adding notes to the transfer, obtaining the other party's response after issuing a reminder, and having a third party witness the transfer in a shared WeChat group. After filing a lawsuit, one can also apply to retrieve the other party's real-name information.

Q3: What should I do if the other party describes the transfer as a repayment?

The other party shall provide evidence to support their claim of "repayment". Since it's a repayment, there must have been a loan beforehand. The other party should explain the time, amount, and evidence of the original loan. If they cannot provide such information, their claim will not be validated.

Q4: Are screenshots of chat records valid as evidence?

Screenshots are just a supplementary tool. The original evidence is the key—you need to bring your original phone to the court to log in and present it; it's more reliable to have important records notarized or stored on the blockchain in advance.

Q5: Can the deleted chat history be restored?

There is uncertainty in the recovery process, so please do not rely on it. It is important to export and back up important conversations in a timely manner. In cases involving large-scale disputes, you can apply to retrieve the platform records or request an appraisal during the litigation process.
