[Direct answer]In the Beijing area, if the money has been repaid but the IOU cannot be recovered, the greatest risk is that the other party may use the original document to "secondary claim the debt". Three remedial measures: When transferring the repayment, note "Repayment of the loan on XX date"; Request the IOU in writing or ask the other party to mark "The full amount has been paid" on the IOU and sign it; Keep the chat records throughout the process. For cash repayments without IOUs, confirm the repayment facts as soon as possible through conversations, witnesses, and on-site monitoring - don't wait until the other party sues before looking for evidence.

I. Problem background and typical scenarios

After repaying the money, not retrieving the IOU is the most dangerous step in private lending. Typical scenarios include: after repaying in cash, the other party claims that the IOU is not with them; after repaying via WeChat transfer, neither party mentions the IOU; and the IOU has been in the other party's hands for years without anyone checking on it. Once the relationship deteriorates, the other party sues with the IOU in hand. If the transfer records are not annotated and the chat records are deleted, "repaying the money" becomes a matter of differing opinions. In such cases of "one debt, two lawsuits" accepted by courts in Beijing, those who suffer most are often the repayers who neglect to leave evidence.

II. Key points of contention

First, the burden of proof for the facts of repayment and the order of the validity of vouchers. Second, the writing requirements for receipts. Third, risk prevention in the case of uncollected IOUs. Fourth, defense strategies when facing a second lawsuit.

III. Professional analysis by Henglue Lawyers

First, the order of effectiveness of repayment receipts: Bank transfers with repayment details noted have the highest effectiveness - all four elements of the transfer subject, time, amount, and purpose must be complete; WeChat and Alipay transfers come next, preferably accompanied by repayment confirmation in chat records; Cash repayments with receipts rank third, with the quality of the receipt determining its effectiveness; Pure cash without any receipts relies entirely on the other party's self-admission and witnesses, with extremely high risks. Second, the writing requirements of receipts: The borrower's name must match the lender's name; Amounts in both numeric and written form must be listed; Specify which loan this repayment corresponds to (loan date, original receipt date, or number); The conclusion sentence "This loan has been fully repaid, and the creditor-debtor relationship is settled" is essential; Signature, fingerprint, and date must be included; Add a statement such as "The receipt has been recovered and is invalid" or "The receipt was returned on [date]" to complete the closed-loop process. Third, standard practices for handling receipts: Most secure - Have the other party write "The full amount has been repaid" on the original receipt and sign it during repayment, keeping the receipt for yourself; Secondly - Recover the original receipt and destroy it in person while recording the process; Thirdly - Request the receipt and proof of its disposition; Least advisable - Do nothing and rely solely on trust. Fourth, defenses against secondary litigation: First, organize repayment records and provide supplementary explanations for missing details regarding the background of fund transfers; Second, retrieve chat records - direct evidence of the parties' conversations about "money has been repaid, receipt to be processed" before and after repayment; Third, locate witnesses and on-site evidence - surveillance footage of the cash repayment location and present witnesses; Fourth, exploit the other party's self-admission - promptly alert the court to inconsistencies in the other party's statements about repayment time and method during trial. Beijing-area courts prioritize reviewing the completeness of repayment evidence and logical consistency, with evidence arranged chronologically to enhance persuasiveness. Fifth, prevention is better than remedy: Always use bank transfers with purpose notes for loan transactions; Conduct on-site settlement and handle receipts immediately during repayment; Use third-party witnesses for large-scale repayments; Regularly reconcile accounts and retain written confirmations. Loan receipt issues are never about trust, but rather about evidence management.

IV. Practical suggestions and legal basis

The first step is to supplement the supporting documents: transfer notes, chat confirmations, and receipts. Supplement all the documents that can be provided immediately. The second step is to send a written reminder: request the original promissory note from the other party or require them to mark it as invalid, and keep a record of the reminder. The third step is to prevent secondary debt: if the other party refuses to cooperate, keep all the evidence of repayment and consider obtaining a notarized backup copy. The fourth step is to respond to litigation: after receiving the lawsuit, sort out the timeline and prepare a defense, rather than responding on the spot. Main legal basis: Articles 557 and 679 of the Civil Code of the People's Republic of China, Articles 15 and 16 of the Supreme People's Court's Interpretation on the Application of Law in Civil Lending Cases; the specific application shall be subject to the currently effective provisions.

VI. Frequently Asked Questions

Q1: What should I do if the other party refuses to return the IOU after repayment?

Require them to issue a receipt or indicate on the IOU that the debt has been repaid and sign it; if they refuse to cooperate, save the repayment records and chat logs for future litigation.

Q2: What should I do if I don't have a receipt for a cash repayment?

As soon as possible, confirm the repayment fact with the other party in the chat, find witnesses who were present and the on-site surveillance footage, and form an evidence chain as soon as possible.

Q3: What should I do if the other party uses the old promissory note to sue me again?

Use repayment records, chat logs, and receipts to refute the fact of repayment; organize the timeline clearly, and the success rate of the defense will be very high.

Q4: What should I pay attention to when repaying a loan via WeChat transfer?

When transferring money, please note in the remarks column "Repaying the loan from year/month", and keep the record of the other party confirming the receipt of the money in the chat history.

Q5: Is it necessary to put a thumbprint on the receipt?

The signature is enough to take effect, but adding a thumbprint and writing the ID card number can further enhance the evidentiary value. It is recommended to add a thumbprint for large sums of money.
