[Direct answer]In the Beijing area, if a lawsuit is filed, the creditor's rights will not be extinguished due to the loss of the IOU—the IOU is just evidence, not the creditor's rights themselves. The approach to supplementing evidence is to reconstruct the "borrowing agreement plus payment of funds plus collection facts" with other materials: transfer records and bank statements to prove payment, chat and call records to prove the agreement and collection, and witness statements to reinforce the process. The party who snatched the IOU may think they're being clever, but their act of grabbing it actually leaves traces (surveillance footage, police reports, and admissions made during the grabbing). Properly using these traces can turn them into favorable evidence. Before filing a lawsuit, it's advisable to report the grabbing incident to the police first to secure the evidence and potentially lay the groundwork for public security or criminal accountability.

I. Problem Background and Typical Scenarios

When collecting debts, if the other party snatches the IOU and tears it up or takes it away, the creditor might say, "Without the IOU, how can you sue them?" The lender instantly loses the core evidence and panics. In fact, the party who snatches the IOU overestimates the importance of the IOU and underestimates the rebuildability of the evidence system.

II. Key points of contention

First, the path of evidence reconstruction after the loss of the IOU. Second, the transformation of evidence of the act of robbery. Third, the litigation strategy when there is no IOU. Fourth, the prevention of similar risks.

III. Professional analysis by Henglue Lawyers

The first layer involves three lines of evidence reconstruction: 1. **Delivery Line**: Bank transfer records, WeChat/Alipay payment statements (with electronic receipts), cash withdrawal records, and eyewitnesses at the scene. 2. **Agreement Line**: Chat records before and after the loan, call recordings (with conversations mentioning amounts, purposes, and repayment timelines being most valuable), draft promissory notes or photos of memoranda (many people take photos and store them in their phones, with checking the photo album being the first step). 3. **Recovery Line**: Chat records about debt collection, responses from the debtor acknowledging the loan and promising repayment ("I will pay you back in a few days" constitutes an admission), and recovery records that also interrupt the statute of limitations. These three lines intertwine to form a closed loop, with courts placing high credibility on "multi-source consistent" evidence combinations. The second layer involves dual utilization of the act of robbery: - **Immediate Reporting**: Administrative penalties or criminal charges (e.g., for extortion or robbery of large sums). The police report and response records confirm the fact that the debt note was taken away by the other party. - **Surveillance, Recordings, and Eyewitness Testimony at the Scene of the Robbery**: Proving the existence of the debt note and its control by the other party—this itself serves as strong circumstantial evidence of the debt note's existence. - **Recorded Remarks During or After the Robbery**: Equivalent to an admission of the loan. The third layer focuses on litigation strategies and details: - Filing a lawsuit regardless of the missing debt note, with the complaint stating the circumstances of the debt note being stolen and attaching the police report. - During trial, focus on evidence chains. If the defendant claims "they repaid the debt and retrieved the note," the burden of proof lies with them (proof of repayment should be provided through receipts or invoices). - For large loans lacking direct evidence, recommend obtaining evidence notarization and preparing witnesses before litigation. - Check the statute of limitations: The three-year statute of limitations begins from the expiration of the agreed repayment period or the refusal to repay. Robbing the debt note often occurs during collection efforts, and police reports can prove the statute of limitations was interrupted. The fourth layer emphasizes prevention: - Provide two copies of the promissory note during lending and store them in the cloud simultaneously. - Use transfers instead of cash for large payments. - Store the promissory note in a safe location, presenting only copies during collection while keeping the original under control. - Record all collection efforts and have witnesses present during the process—evidential habits determine the upper limit of legal protection.

IV. Practical suggestions and legal basis

The first step is to immediately report the theft of the IOU to the police and keep the receipt and on-site evidence. The second step is to comprehensively organize the three types of evidence for reconstruction: transfer records, chat logs, and witness statements. The third step is to state the process of the IOU's loss in the lawsuit and require the other party to provide evidence of "already repaid the debt". The fourth step is to check the statute of limitations and interrupt the renewal period with collection records. The main legal basis includes Articles 667 to 668 and Article 188 of the Civil Code, the Civil Procedure Law and the provisions on civil litigation evidence, Article 49 of the Public Security Administration Punishment Law; the specific application shall be subject to the currently effective regulations.

5. Henglue Law Firm's Reminder

Three key points about a lost IOU: Even if the IOU is lost, the creditor's claim still exists, and the evidence chain can be rebuilt; Reporting the case to the police achieves two goals at once—it not only holds the perpetrator accountable but also serves as circumstantial evidence; If the other party claims they have already repaid the money, ask them to provide proof. The burden of proof lies with them, not you.

VI. Frequently Asked Questions

Q1: Will the lawsuit be accepted if there is no promissory note?

Yes; the filing of a case does not require a promissory note as a prerequisite. Transfer records and chat records, among other things, can form an evidence chain and be used to initiate a lawsuit. After the case is accepted, the court will make a comprehensive determination of the facts.

Q2: What should I do if there's no transfer record for the cash loan?

The evidence can be supplemented with cash withdrawal records, witnesses present at the time of delivery, and chat records or audio recordings in which the other party admits the loan; it's difficult to prove cases involving only cash without any supporting evidence. Therefore, it's better to use bank transfers when lending money.

Q3: Does forcibly taking a promissory note constitute a crime?

Taking or grabbing something by force or coercion that meets the statutory circumstances can constitute a crime, and in general cases, it can also be subject to public security punishment; reporting the case to the police and keeping records can serve both the purposes of holding those responsible accountable and providing evidence.

Q4: Is the video of the other party tearing up the IOU and taking a photo of it on the spot useful?

It's very useful. The act of tearing up the IOU itself proves the existence of the IOU and the borrower's intention to refuse to repay the loan. The video combined with the police report is the most powerful combination.

Q5: Can a copy of the IOU be used as evidence?

The copy cannot be used as the sole basis for making a decision, but it can be admitted as evidence after being corroborated by transfer records, chat logs, etc. If there is a copy, it should be submitted simultaneously and an explanation should be provided regarding the loss of the original document.
