[Direct answer]In the Beijing area, if the IOU is torn up by the debtor, it does not necessarily lead to a loss of the case. The lender can first fix the fact of tearing up the IOU, and then collect transfer vouchers, chat records, collection records, witness statements, etc. to form a complete chain of evidence. If the original is lost, destroyed or damaged, the lender can submit a copy in accordance with Article 111 of the Interpretation of the Supreme People's Court on the Application of the Civil Procedure Law of the People's Republic of China (amended in 2022) and combine it with other evidence to determine the facts. If the debtor intentionally destroys the documentary evidence unfavorable to himself, it can be presumed that the facts claimed by him do not exist. The statute of limitations is three years. It is recommended to sue as soon as possible and apply for property preservation if necessary.

I. Problem Background and Typical Scenarios

When collecting debts, the borrower's note is snatched and torn up by the other party; during the account reconciliation, the documentary evidence is destroyed on the spot; or the borrower's note is damaged together with the fire or water stains. These are not uncommon scenes in private lending. Many people's first reaction is that the borrower's note is gone and the money can't be recovered, so they just give up. In fact, the court always assesses the lending relationship based on more than just a piece of paper. It reviews whether the lending agreement and the payment of the funds can be proven by evidence. Transfer records, chat records, call recordings, witness testimonies, and repayment agreements signed afterwards can all serve as alternative proofs. What people really need to be vigilant about is not fixing any evidence in time after a conflict occurs, resulting in the creditor's claim being left hanging. The relevant evidence-gathering approach can be referred to for reference.Legal services for creditor-debtor disputes and enforcement cases.

II. Key points of contention

The controversy focuses on four points. First, whether a lending relationship exists: the lender needs to prove the lending agreement and the delivery of funds. After the original documents are lost, the lender can use a combination of transfer records, chat records, and collection records to complete the proof. Second, the debtor's common defenses: the funds have been repaid, the transfer was a loan or a gift, or the loan has been repaid by a third party, etc. The debtor needs to provide evidence for these defenses. Third, the legal significance of the act of destroying evidence: if the lender can prove that the other party controls the documentary evidence and refuses to submit it without a legitimate reason or maliciously destroys it, the lender can claim that the content of their claim is untrue, and the court can also take compulsory measures against the act of destroying evidence according to law. Fourth, the standard of proof: if the lender's evidence can make the facts to be proved highly probable, the court shall recognize it in accordance with Article 108 of the Interpretation of the Supreme People's Court on the Application of the Civil Procedure Law of the People's Republic of China (amended in 2022). In the judicial practice of Beijing, cases with a complete chain of evidence will not result in a loss of the case just because the original documents are lost.

III. Professional analysis by Henglue Law Firm

A case handled by Attorney He Ningning demonstrated the value of a complete chain of evidence. The client, Liu **, and Zhang ** were friends. Around 2022, Zhang ** asked Liu ** to borrow money from a bank in her own name and then lend the funds to herself for use. Liu ** agreed and signed a "Personal Loan Contract" with the bank. After the bank disbursed the loan, Liu ** transferred the full amount to Zhang **. When Zhang ** failed to repay the loan on time, the bank sued Liu ** multiple times without success, demanding repayment of the principal, interest, penalty interest, and compound interest. Liu ** found herself in a dilemma of acting as a guarantor for others' loans and bearing the debt herself. After accepting the case, Attorney He Ningning immediately sorted out the bank loan contract, disbursement records, transfer records, chat records between the parties, and overdue collection documents to form a complete chain of evidence. He then determined a step-by-step plan: first, mediate with the bank to stop losses, and then seek recovery of rights from the actual borrower. On June 12, 2026, Liu ** and Zhang ** reached a mediation agreement: Zhang ** agreed to repay the principal of 170,000 yuan and the funding occupation loss of 10,000 yuan in installments. If any installment was overdue, the remaining principal would be subject to a 3% annual interest rate starting from June 25, 2026. The parties jointly applied for judicial confirmation to the Beijing Fengtai District People's Court, which issued a civil ruling confirming the legality and validity of the mediation agreement. However, Zhang ** failed to make any payment on the first installment. Attorney He Ningning immediately initiated enforcement proceedings, submitting enforcement applications and online investigation requests to query the debtor's bank accounts, WeChat, Alipay, vehicles, and real estate and take freezing and seizure measures, ultimately recovering the full amount. This case highlights that when there are flaws in written evidence, timely supplementing other evidence and securing creditor's rights remains the fundamental basis for protecting rights. The case was handled by Beijing Henglu Law Firm.He NingningAttorney (Practice Certificate No.: 11101202511925103, subject to the certificate issued by the judicial administrative organ) acting as an agent.

IV. Practical suggestions and legal basis

The legal basis includes Article 667 of the Civil Code of the People's Republic of China (effective from January 1, 2021) (definition of loan contracts), Article 679 (loan contracts between natural persons are established when the lender provides the loan), and Article 188 (three-year statute of limitations); the provisions of the Civil Procedure Law of the People's Republic of China (amended on September 1, 2023 and effective from January 1, 2024) regarding the submission of original documentary evidence and coercive measures to obstruct civil litigation; Article 111 (circumstances where it is difficult to submit original documents) and Article 108 (standard of proof with a high degree of probability) of the Interpretation of the Civil Procedure Law of the People's Republic of China (amended in 2022); and Article 90 (copies that cannot be verified with the originals cannot be used as the sole basis for determining the facts of the case) of the Several Provisions of the Supreme People's Court on Evidence in Civil Procedure (amended on December 25, 2019 and effective from May 1, 2020).

5. Henglu Law Firm's Reminder

The act of tearing up documents often occurs during conflicts over debt collection. The more intense the emotions are, the more important it is to be aware of the need for evidence: first record the scene with your phone, then discuss the matter. After the original documents are lost, the preservation window for electronic data is very short. Deleting chat records by mistake or replacing old phones will all lead to the loss of opportunities to supplement evidence. Also, don't believe the argument that if the other party tears up the documents, you don't need to repay them. Destroying evidence not only doesn't exempt you from your debt obligations, but may also result in unfavorable consequences for you.

VI. Frequently Asked Questions

Q1: If the IOU has been torn up, can I still win the lawsuit?

There is a possibility of winning the case, but it all depends on whether the chain of evidence is complete. Transfer records can prove the delivery of funds, chat records and call recordings can prove the agreement on the loan, and collection records and witnesses can corroborate that the debt has not been repaid. Together, these pieces of evidence are enough to make the facts to be proven highly probable. If the other party maliciously tears up the IOU, the court can also make them bear the adverse consequences according to law. Conversely, if there are only oral statements and no delivery receipts, the risk will obviously increase. The outcome of the case depends on the evidence and the court's determination, and no lawyer can guarantee victory or defeat on their own.

Q2: After the IOU has been torn up, what evidence should be provided to supplement it?

They can be divided into four categories according to their priority: 1. Evidence of delivery, such as bank transfer receipts, WeChat or Alipay transaction records, and cash withdrawal receipts. 2. Evidence of agreement, including chat records mentioning the loan amount and repayment period, call recordings, and messages from the other party acknowledging the debt. 3. Evidence of the act of repayment, such as on-site photos and videos, police reports, and contact information of witnesses present at the scene. 4. Evidence of post-event confirmation, including repayment agreements signed retroactively, reconciliation statements, and installment repayment commitments. The evidence should be organized chronologically, and electronic data should retain their original carriers with screenshots indicating their sources.

Q3: How much does it cost to file a lawsuit?

The litigation fees shall be paid in accordance with the "Measures for the Payment of Litigation Fees" (State Council Decree No. 481, implemented on April 1, 2007), calculated cumulatively by the litigation subject amount. For cases applying the summary procedure, the fees shall be reduced by half. The losing party shall ultimately bear the fees, and the party partially successful shall share the fees proportionally. For applications for property preservation, an additional preservation application fee shall be paid, subject to a maximum limit. Lawyer's fees shall be determined through consultation between the law firm and the client. Commonly, fees are charged based on the litigation subject amount or on a per-case basis. There is no unified government pricing for legal fees. Before entrusting a lawyer, the client should clarify the fee stages and refund rules in advance.

Q4: How long does it usually take to handle cases like this?

When the evidence is complete and the defendant cooperates, the case can be concluded through a summary procedure within three months and through a regular procedure within six months. However, if the defendant's whereabouts are unknown and service needs to be effected by public notice, the service process alone may take several months. For applications for property preservation before or during litigation, the preservation ruling is generally issued relatively quickly. If the case enters the stage of enforcement, it will take additional time to investigate and dispose of the property. In the cases handled by Attorney He Ningning, after the mediation agreement was judicially confirmed, the other party could skip litigation and proceed directly to enforcement if it breached the contract, which significantly shortened the recovery period. The overall timeframe varies greatly depending on the completeness of the evidence and the defendant's cooperation.

Q5: If I find that the IOU has been torn up, what should I do first?

There are four steps to take: First, stay calm and first fix the fact of the destruction. Take photos and videos, find witnesses on the scene, and call the police if necessary; Second, within three days, export all transfer records, take screenshots to preserve chat records, and make a data backup if you change your phone; Third, use traceable methods such as WeChat and text messages to collect payments from the other party and require them to confirm the amount of the loan; Fourth, entrust a lawyer to evaluate the evidence chain. If no agreement can be reached, promptly sue and apply for property preservation to prevent the other party from transferring assets. Try to complete all fixed actions within one week, and the earlier you do it, the more proactive you will be.
