[Direct answer]In the Beijing area, enterprises collecting overdue payments should organize materials based on the legal relationship and the facts of the overdue payments, which typically include: contracts or orders signed by both parties; delivery notes, acceptance notes, and receipt certificates; reconciliation statements and settlement documents; invoices and payment records; communication records of collection such as letters, WeChat messages, and emails; guarantee contracts, materials of guarantors or mortgages; the other party's industrial and commercial registration and basic information; and evidence related to the statute of limitations. Article 577 of the Civil Code of the People's Republic of China (effective January 1, 2021) stipulates that if a party fails to perform its contractual obligations or performs them in a manner inconsistent with the contract, it shall bear contractual liabilities such as continuing to perform, taking remedial measures, or compensating for losses. The more complete the materials are, the more solid the foundation for negotiation and litigation will be.

1. Problem background and typical scenarios

The outcome of debt disputes often hinges on evidence. Typical scenarios include: only verbal agreements without written contracts; delivery notes lacking the signatures of the other party's personnel; unconfirmed account statements; invoices issued but no payment receipts; long-term WeChat communication but no formal account settlement; and the other party's defense that the payment has been settled or that the funds belong to others. When handling such matters in the Beijing area, lawyers usually first sort out the evidence chain and statute of limitations.Creditor's rights and debts, and enforcementIn business, the consistency of evidence is more important than the quantity of individual materials.

Focus One: Whether a contractual relationship exists and whether the parties involved are qualified. Focus Two: The calculation of the outstanding debt amount and the payments already made. Focus Three: The validity of receipt and acceptance certificates. Focus Four: The binding force of account statements and settlement agreements. Focus Five: The calculation and interruption of the statute of limitations. Focus Six: The scope of the guarantor's liability. Focus Seven: How to respond when the other party defends against claims by arguing that the funds belong to others or that the payment has already been settled.

III. Professional analysis by Henglue Lawyers

Henglue Law Firm advises that the best weapon against a defense is a complete chain of evidence. Taking a machinery equipment leasing contract dispute handled by Attorney Zhu Guiying of our firm as an example: The company provided equipment leasing services to another company, with total fees amounting to over 2.5 million yuan. However, the other party only paid 1.2 million yuan, leaving a balance of over 1.3 million yuan unpaid. The other party refused to pay on the grounds that a closed agreement had been signed and the payments had been finally settled, and claimed that over 1.01 million yuan of the total amount belonged to the project funds of a third party. The attorney used the evidence of account reconciliation to break through the barrier of the closed agreement: Although the closed agreement stated the so-called total final settlement price, the two parties subsequently conducted multiple account reconciliations, confirming the addition of new fees and unpaid accounts. At the same time, based on the principle of contractual relativity, the attorney pointed out that the payments should belong to the parties to the case and have nothing to do with the third party. The first-instance court fully supported the claim and ordered the payment of the arrears and interest. After the other party appealed, the second-instance court upheld the original judgment.

VI. Frequently Asked Questions

Q1: If there's only a delivery note but no contract, can I get my money back?

This can be claimed, but a complete chain of evidence is required. The delivery note must be signed by the other party's staff, and it is best to combine it with the order, communication records, invoices, and partial payment records to corroborate each other, demonstrating the existence of a genuine transaction relationship and the fact of the debt between the two parties. If the identity of the signatory is in doubt, it can also be corroborated by their position, communication records, and other means to prove that they represent the other party in receiving the goods.

Q2: Do account statements have legal validity?

Yes, they usually have strong evidentiary value. A reconciliation statement signed and confirmed by the other party can be regarded as a settlement confirmation of the funds that have been paid; even if the reconciliation content in the emails or WeChat messages between the two parties can reflect the other party's acknowledgment of the amount of the debt, it can also be used as evidence. Therefore, it is recommended to conduct regular reconciliations and try to obtain the other party's written or electronic confirmation as much as possible.

Q3: What should I do if the other party says the payment has been settled?

There are two ways to address this: First, verify the true meaning and scope of the so-called settlement documents. If there are subsequent transactions or reconciliations between the parties, the previous settlement may not cover all the payments. Second, based on the principle of contractual relativity, argue that the payments should belong to the parties to the case and have nothing to do with third parties. It is recommended to keep the vouchers of subsequent reconciliations and new transactions.

Q4: Can I still sue someone if the debt has been outstanding for more than three years?

You can file a lawsuit, but you may face a statute of limitations defense. The general statute of limitations period is three years, calculated from the date when the right holder knows or should have known that their rights have been infringed and the date when the obligee becomes aware of the infringement. If there are circumstances such as debt collection, account reconciliation, or partial performance by the other party during this period, it may constitute an interruption of the statute of limitations. It is recommended to sort out the transaction records as soon as possible and have a lawyer evaluate the statute of limitations situation.

Q5: Should I apply for preservation of evidence before filing a lawsuit?

It depends on the circumstances. If there are signs of the other party transferring assets or experiencing a deterioration in their business operations, applying for property preservation can help ensure the enforcement of future judgments; preservation usually requires providing a guarantee. Whether to apply for it should be determined based on a comprehensive assessment of the case amount, the other party's repayment ability, and the associated costs. It is recommended to evaluate and arrange this together with the lawsuit.

The above answer is based on the judicial practice in Beijing. The adjudicative guidelines in other provinces or cities may differ. For specific cases, please refer to the local rules and evidence situation.

If you are facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with the evidence materials, to avoid missing the statutory time limit. →Legal services for creditor-debtor disputes·Attorney Zhu Guiyin·Beijing Henglu Law Firm
