Private Lending in China: How to Prove and Enforce a Loan to a Chinese Borrower

You lent money to a Chinese business partner, friend, or relative. There is no formal loan agreement. Can you get your money back? Yes — if your evidence chain is complete. Here is how Chinese courts evaluate private lending claims, based on a real RMB 6.35 million case.

The RMB 6.35 Million Debt That Lived in a WeChat Conversation

Two businessmen had co-invested for over 20 years. After a major asset sale, one partner was owed RMB 6.5 million. The debtor made three partial payments totaling RMB 150,000. The remaining RMB 6.35 million went unpaid for years. There was no formal loan agreement — only a debt acknowledgment signed by the debtor, bank transfer records of the partial repayments, hundreds of WeChat messages in which the debtor repeatedly admitted the debt and discussed repayment plans, and voice recordings of telephone conversations. When the creditor finally sued in the Haikou Meilan District Court, the evidence — taken together — was sufficient to win. But the case illustrates a critical point: in Chinese private lending litigation, no single piece of evidence is enough. It is the chain that wins.

The Legal Framework

Private lending between individuals is legal in China and governed by the Civil Code (Book III, Contracts) and the Supreme People’s Court’s 2020 Provisions on Private Lending Cases. The key legal requirements:

The plaintiff bears the burden of proving the existence, amount, and terms of the loan. A court will find a private lending relationship exists if the plaintiff can produce an IOU, a receipt, a promissory note, or other debt instrument — plus proof that the funds were actually delivered.

An IOU proves the existence of a promise to lend. It does not, by itself, prove that the funds were actually transferred. The plaintiff must also prove delivery — through bank transfer records, cash withdrawal receipts, witness testimony, or contemporaneous documentary evidence. This is the most common point of failure in private lending cases.

Under the 2020 SPC Provisions, the maximum enforceable interest rate is four times the one-year Loan Prime Rate (LPR) — currently approximately 14.6% per annum. Any interest rate exceeding this cap is unenforceable.

The statute of limitations is three years under Article 188 of the Civil Code. A partial payment or a written acknowledgment of the debt interrupts the period and resets the clock. In the RMB 6.35 million case, the debtor’s repeated partial payments and WeChat admissions kept the claim alive for years.

The Five Elements of a Winning Evidence Chain

1. The Debt Instrument. An IOU handwritten by the debtor, dated, and bearing the debtor’s signature or seal is the strongest form. An IOU that states the amount, debtor’s name, repayment date, interest rate, and purpose of the loan is ideal. A typed IOU signed by the debtor is acceptable but slightly weaker — handwriting can be authenticated; a typed document with a signature alone cannot.

2. Proof of Fund Delivery. Bank transfer records are the strongest form. Cash delivery is substantially harder to prove. If you must deliver cash: do it in the presence of a witness who can testify, withdraw the funds from your bank account on the same day to create a contemporaneous record, and have the debtor sign a receipt.

3. Electronic Communications. WeChat messages, SMS messages, and emails in which the debtor acknowledges the debt, discusses repayment terms, or admits to being in default are highly valuable. They must be authenticated: the original device must be available, the debtor’s identity must be verified (ideally through WeChat Pay real-name records), and the conversation must be complete and unedited.

4. Audio Recordings. Secretly recorded telephone conversations are admissible in Chinese civil litigation provided: the recording was not obtained through coercion, fraud, or illegal means; the recording is complete and unedited; and the recording is transcribed and verified by the court. A telephone conversation in which you raise the debt and the debtor does not deny it — but instead discusses repayment — is a powerful form of tacit admission.

5. Witness Testimony. A neutral third party who witnessed the loan agreement, the delivery of funds, or the debtor’s subsequent acknowledgments can provide corroborating testimony. The witness must appear in court — written statements without in-person testimony have limited evidentiary value.

No single element is sufficient. The combination of an IOU, bank records, WeChat acknowledgments, and a consistent witness is close to unassailable. The chain is the case.

From Judgment to Recovery: The Enforcement Path

Apply for asset preservation simultaneously with filing the complaint — before the debtor is served — to preserve the element of surprise. Use an insurance guarantee rather than a cash deposit. Investigate the debtor’s assets before filing: real estate holdings, vehicle registrations, equity, accounts receivable. A judgment against a debtor with no known assets is a hollow victory.

Practical Protocol: Before You Lend

Execute a written IOU, handwritten by the debtor, with ink on paper. State: debtor’s full name and national ID number, creditor’s full name, loan amount in both digits and Chinese characters, repayment date, interest rate, and purpose. Debtor signs and dates.
Transfer the funds by bank wire, not cash. The bank record is your proof of delivery.
Verify the debtor’s WeChat identity by sending a small payment. A RMB 0.01 transfer through WeChat Pay establishes the debtor’s real-name identity permanently.
If the debtor misses a repayment, send a written demand through WeChat or SMS within 30 days. The response becomes evidence that can reset the statute of limitations.
If the debt approaches the three-year limitation period, obtain a written acknowledgment or a partial payment. Either will reset the clock.

Conclusion

Private lending to a Chinese borrower is enforceable — but only if you build your evidence chain before the dispute arises. The five elements — debt instrument, proof of delivery, electronic communications, audio recordings, and witness testimony — reinforce each other. The creditors who recover are not those with the most favorable IOU. They are those who treated the loan like a litigated dispute from the day the money left their account.
