[Direct answer]In the Beijing area, individuals cannot access bank account statements before filing a lawsuit—this is due to personal information protection and bank confidentiality obligations, which restrict individuals from retrieving their own records. Lawyers also cannot directly retrieve these records before the case is filed. All legal procedures must be conducted within the litigation process: after the case is filed, applying for court investigation and evidence collection or a lawyer's investigation order; applying for property preservation to freeze the other party's account (providing account clues is sufficient, no need to know the balance); and after entering the enforcement process, the court will conduct a comprehensive inquiry through the online investigation and control system. Before filing a lawsuit, individuals can only do two things: organize the transaction records in their possession and seize the opportunity to apply for pre-litigation preservation.

1. Problem background and typical scenarios

"There's clearly money in his account. Could I first verify it and then file a lawsuit?" — Almost all creditors have asked this question. Their feelings are understandable, but there's no legal way for individuals to retrieve others' bank transaction records: these records belong to personal financial information, and banks are legally obligated to keep client information confidential. Without court orders, no one (including lawyers) can access them. There are also unofficial channels for "finding someone to check bank transaction records", but not only is the information source illegal and the evidence invalid, but both the client and the provider may also violate the crime of infringing on citizens' personal information — this shortcut is a minefield.

II. Key points of contention

Firstly, why can't the court investigate and collect evidence of substitute actions before the lawsuit is filed? Secondly, what is the application process for investigation and evidence collection after the case is filed? Thirdly, how to ensure the seamless connection between preservation freezing and account inquiry? Fourthly, what is the coverage of online investigation and control in the execution stage?

III. Professional analysis by Henglue Lawyers

The first layer concerns pre-litigation boundaries and alternative actions: Bank transaction records belong to personal financial account information. The Personal Information Protection Law and banking regulatory rules stipulate that their retrieval must have a legal basis. In the pre-litigation stage, there are no case acceptance procedures, and the court will not issue investigation orders. At this time, what can be done is to organize the transaction records between oneself and the other party in one's own account (one's own transaction records can be retrieved at any time, which itself is a key evidence to prove the loan and payment relationship); collect clues to the other party's account (account numbers and opening banks in historical transfer records); and assess the risk of property transfer to decide whether to apply for pre-litigation preservation. The second layer concerns investigation paths after case filing: Lawyer's investigation orders - After the case is filed, the attorney can apply to the court for investigation orders and use the orders to retrieve the other party's designated account transaction records, which are related to the disputed facts of the case; Court-initiated investigation - Evidence that the parties cannot collect on their own can be applied to the court for retrieval; when applying, it is necessary to explain the relevance of the account clues to the facts to be proven. A general application for "retrieving all accounts" is usually not permitted; common effective scenarios include checking the other party's receiving account transaction records to prove the regularity of fund flows and checking the repayment account transaction records to prove the facts of repayment or misappropriation. The third layer concerns the connection between preservation and inquiry: When applying for litigation preservation, provide account clues (account numbers or opening banks), and the court will freeze the account through the online inquiry and control system, with the freezing amount limited to the creditor's claim; the account information (balance, opening bank) retrieved by the court during the preservation stage itself can reflect the other party's property status, which is of great reference value for subsequent litigation strategies; it is necessary to remember the requirement of suing within 30 days after pre-litigation preservation. Preservation is not a tool for delaying, but an action to cooperate with litigation. The fourth layer concerns inquiry and control during the enforcement stage: After the judgment takes effect and enters the enforcement stage, the court conducts batch inquiries into bank, third-party payment (WeChat, Alipay), securities, vehicles, real estate, etc. information through the online enforcement inquiry and control system, with the coverage far exceeding that during the litigation stage; directly freezing and deducting the discovered property; the defaulter who conceals and transfers property faces fines, detention, and even prosecution for refusing to execute the judgment - the inquiry and control intensity during the enforcement stage has actually solved the vast majority of the needs for "retrieving transaction records". The fifth layer concerns the strategy of evidence application: Organize the transaction records in one's own account according to the timeline, mark the corresponding contracts or facts of each payment, and form a comparison table of income and expenditure; the part of the transaction records (received in one's own account) that the other party has transferred for repayment can be inferred from it; calculate the interest and overdue losses in the litigation request, and the evidence of the transaction records supports which part, and the claim covers which part. In Beijing area courts, the issuance of investigation orders is strictly controlled, but the path is smooth. When applying, it is necessary to write down the account clues, the facts to be proven, and the explanation of the inability to collect evidence on one's own in a solid manner, and the pass rate is not low.

IV. Practical suggestions and legal basis

The first step is to review old accounts: immediately print and archive your transaction records to create a comparison table of income and expenditure. The second step is to collect clues: register all account numbers and bank branch information from historical transfers. The third step is to follow procedures: after filing a case, apply for an investigation order or court evidence collection, and cooperate with the preservation and freezing of assets. The fourth step is to rely on enforcement: after the judgment takes effect, apply for forced execution, and conduct comprehensive online investigations and controls. Main legal basis: Articles 67, 103 to 108 of the Civil Procedure Law of the People's Republic of China, and relevant rules of Article 20 and Article 41 of the Supreme People's Court's Interpretation on Evidence in Civil Procedure; specific application shall be subject to the currently effective provisions.

VI. Frequently Asked Questions

Q1: Is it illegal to pay someone to check one's transaction records?

Illegal. Illegally obtaining others' bank transaction records is suspected of violating the crime of infringing citizens' personal information, and the evidence obtained illegally cannot be used in litigation.

Q2: At what stage can an investigation order be applied for?

After the case is accepted, the applicant can apply for it, and the court will review and issue the order. The lawyer can then use the order to retrieve the transaction records of the designated account from the bank.

Q3: What should I do if I don't know the other party's account information during the preservation process?

You only need to provide the clues of the opening bank or the account number. The court will query and freeze the account through the online investigation and control system, so you don't need to know the balance of the account.

Q4: How long ago can I check the other party's transaction records?

Applications can be submitted during the period related to the disputed facts of the case, which usually covers the period before and after the transaction and the period during which the dispute arose.

Yes. The online enforcement and control system covers the balance and transaction records of third-party payment accounts, and the freezing and deduction can be completed in one go.
