[Direct answer]In the Beijing area, electronic evidence that can be considered valid and have strong probative force — the transfer notes are a unilateral expression of intent made at the time of payment. After being corroborated by WeChat chat records and debt collection dialogues, most courts recognize that they can initially prove the lending agreement and the delivery of funds. However, we should clearly see its two shortcomings: the notes are unilateral, and if the recipient does not respond or has a reasonable explanation, other evidence is needed to reinforce it; in the complex transactions of amounts and relationships (confusion between partnership funds, loans, and gifts), it is difficult to distinguish the nature of the transactions solely based on the notes. Two public cases are the best examples of both positive and negative outcomes.

1. Problem background and typical scenarios

When acquaintances borrow money, they often feel too embarrassed to write a promissory note. Instead, they simply add a note saying "loan" when transferring the money via WeChat. The lender might think everything is fine, but when the borrower refuses to repay, they might argue, "That was a payment for goods" or "That was a repayment." In the end, such notes are of little legal significance and often become a common point of contention in court.

II. Key points of dispute

First, the evidentiary value and boundaries of the notes. Second, the methods of supplementing the chat records. Third, the key points of defense and offense in the opponent's defense. Fourth, the standard procedures for preserving evidence in advance.

III. Professional analysis by Henglue Law Firm

First, legal evaluation of transfer notes: Transfer notes are a form of expression of the lender's intention to lend money immediately upon the delivery of funds, and their authenticity is verified by the payment platform's records, making them less susceptible to forgery. Courts generally regard them as preliminary evidence of lending consent—combined with the actual receipt of funds, they support half of the two key elements of civil lending (consent and delivery). Let's look at a positive example: In a dispute heard by the Xihu District Court of Nanchang City, Chen * transferred 50,000 yuan to Liu * via WeChat in two installments and labeled the transfers as "loans". Although no loan agreement was signed, the court confirmed the existence of lending consent based on the transfer notes and WeChat chat records, and ordered Liu * to repay the principal and interest. The notes and chat records corroborated each other, demonstrating that unilateral notes can also establish a case. Second, warnings from counterexamples: In a case heard by the Longhua District Court of Haikou City, Chen * sued Qiqi * for repaying 980,000 yuan labeled as "loans". The court found that the notes were made in response to bank inquiries, and evidence such as chat records and creative agreements showed that the funds were actually royalties for comic studio work. The lending consent was not established, and all claims were dismissed. The contrasting conclusions of the two cases are clear: Transfer notes can only hold up if they "align with the actual lending consent". If the notes are a tool to conceal other legal relationships, chat records will expose them. The focus of evidence is on the overall chain of evidence, not individual labels. Third, reinforcement and defense: Lender-side reinforcement checklist—dialogues about loan purpose, amount, and repayment time before and after the transfer, the other party's response to collection efforts ("I'll pay you back later") during collection, voice call records, and the other party's statement about their financial situation at the time of borrowing. Recipient-side common defenses and solutions—for claims of "being payment or partnership funds", require the defendant to provide evidence of the underlying legal relationship (contracts, reconciliation records), with the burden of proof on the defendant; for claims of "deleting chat records", request the court to retrieve payment platform transaction details and original phone data, ensuring the original carriers are not overwritten. Fourth, pre-evidence preservation norms: Specify "loan" in the transfer notes and add the borrower's name; complete loan communication and transfer in the same chat window (avoid cross-platform disruptions); insist on signing loan agreements or requiring receipts for large loans, with WeChat evidence as supplementary; document collection efforts in writing rather than oral transcriptions to avoid language distortion; export WeChat records and retain original phones before litigation; and notarize large electronic evidence—the probative value of electronic evidence never lies in the technology itself, but in its "instantaneous formation and complete chain of evidence".

IV. Practical suggestions and legal basis

The first step is to note the loan details in the transfer remarks and keep the full chat history; the second step is to regularly send payment reminders and keep written records to document the other party's responses; the third step is to export the original records and have them notarized after a dispute arises, and not to delete the records without clear justification; the fourth step is to provide chat records as evidence to support claims during litigation and require the other party to provide evidence to the contrary. Main legal basis: Articles 667 and 668 of the Civil Code; the Civil Procedure Law and the Supreme People's Court's Several Provisions on Evidence in Civil Litigation (regarding electronic data); the Online Litigation Rules of the People's Courts; specific applications shall be subject to the currently effective regulations.

5. Henglu Law Firm's Advice

Three key points for WeChat loan disputes: 1. The chat record serves as preliminary evidence, but it must be corroborated by other evidence to be legally binding. 2. If the other party disputes the claim, they must provide proof. Never delete the original chat records! 3. For large-amount loans, a written loan agreement is essential. WeChat evidence should be used as supplementary evidence, not as the sole basis for a claim.

VI. Frequently Asked Questions

Q1: Can you win even if there are only notes but no chat records?

There are precedents of winning lawsuits, but the risks are high. It is recommended to collect evidence of the agreement through collection dialogues before suing, or apply for retrieving the platform's transaction details as supporting evidence. It is not advisable to sue rashly based on a single piece of evidence.

Q2: What should I do if the other party says the notes were written randomly?

The notes form an instant record that cannot be tampered with afterwards. If the other party wants to refute them, they must provide a reasonable explanation and present evidence to prove the opposite legal relationship. The burden of proof lies with them.

Q3: Can WeChat voice messages be used as evidence?

Yes; voice is considered electronic data. It's enough to keep the original carrier and organize the text draft, as long as the key content is clear and complete, it can be accepted as evidence.

Q4: Can the deleted chat history be restored?

It's difficult to recover deleted local data by oneself. You can apply to the court to retrieve the transaction information stored by the payment platform, or restore it with cloud backup. It is recommended to regularly back up important daily records.

Q5: Which has higher legal effect, a promissory note or a WeChat note?

A promissory note is a special creditor's receipt with superior legal effect. When the two documents coexist, they can corroborate each other, providing stronger legal basis for claims. Only promissory notes with annotations will be recognized as electronic evidence according to relevant legal rules.

[Case No.]The case number has not been made public.
[Trial Court]The People's Court of Longhua District, Haikou City, Hainan Province
[Judicial Summary]Chen Daming sued, claiming that the transfer of more than 980,000 yuan to Qiqi via WeChat with a note indicating a loan was actually a lending transaction. The court found that the transfer note was made in response to the bank's inquiry, and evidence such as chat records and creative agreements showed that the funds were actually payment for the comic studio's work. The loan agreement was not established, and the court ruled to dismiss all of Chen Daming's claims. Comparing this case with successful litigation cases, it shows that there is a huge risk when there is only a note but the agreement is questionable.
