[Direct answer]In the Beijing area, the establishment of a right of retention requires the simultaneous fulfillment of four conditions, all of which are indispensable. First, lawful possession: The creditor must lawfully possess the debtor's movable property, and the acquisition of possession must have a legal basis. If the possession itself is illegal, the right of retention will not be established. Second, the same legal relationship: The movable property subject to retention and the creditor's claim must be based on the same legal relationship, such as a contractor retaining the contracted goods, a repairer retaining the repaired items, or a transporter retaining the consigned goods. Third, the debt has reached the repayment period: If the creditor's claim has reached the performance deadline but the debtor has still not repaid the debt, the debtor may raise a defense of repayment and the right of retention will not be established. Fourth, the movable property belongs to the scope of retention: According to Article 453 of the Civil Code of the People's Republic of China (effective January 1, 2021), the movable property subject to retention shall belong to the creditor's property, unless otherwise provided by law. Therefore, ownership attribution is an important criterion for judgment. In terms of exercise, the creditor shall notify the debtor and grant the debtor a reasonable period of time. If the debtor still fails to perform within the time limit, the creditor may agree with the debtor on a discounted payment or may prioritize compensation from the proceeds of the auction or sale of the retained movable property. It should be noted that the right of retention is a statutory guarantee right. If other guarantee methods exist simultaneously, the order of priority of compensation and the method of realization will be affected.Creditor's rights and debts, and enforcementThe column provides a detailed explanation of the realization of security rights and creditor's rights.

1. Problem background and typical scenarios

The parties who consult on such issues are often in a state where they have legally detained the other party's property, but are unsure whether they can claim priority compensation based on this. There are four common scenarios: the processing party detains the items entrusted for processing; the repair party detains the equipment sent for repair; the transportation party detains the goods for which the freight has not been paid; and the construction party detains the project materials or retained components. Common confusions include: whether the items in hand can be considered retention, how long a deadline is needed to sell them, and how to respond when the other party defends on the grounds that the ownership does not belong to them. The most common reasons for failure in practice are illegal possession, such as substituting seizure for retention, forcibly occupying or possessing based on a revoked basis; secondly, the lack of establishment of the same legal relationship, such as the detained items having no connection with the claimed debt; thirdly, claiming retention before the debt has matured. In addition, there is a common misconception that as long as you detain something, you can claim priority compensation. In fact, you must also go through the procedures of notification and reasonable time limit. Procedural defects may lead to insufficient protection.

II. Key points of dispute

The first focus is the source and method of obtaining the legality of the creditor's possession. The second focus is whether the pledged movable property and the creditor's claim stem from the same legal relationship. The third focus is whether the debt has reached the repayment period. The fourth focus is whether the pledged movable property belongs to the debtor's property. The fifth focus is the calculation of the notice and reasonable time period. The sixth focus is the order of compensation when the pledged items and the collateral coexist. The seventh focus is the procedural requirements for discounting, auction, and sale. The eighth focus is the connection between the right of retention and litigation and enforcement. In addition, attention should also be paid to the risk allocation of the pledged movable property being damaged or lost during the retention period, the legal consequences of claiming retention before the creditor's claim matures, and the appropriateness requirements when the value of the pledged items significantly exceeds the amount of the creditor's claim.

III. Professional analysis by Henglue Lawyers

From the perspective of guarantee rights practice, the effectiveness of exercising the right of retention highly depends on the grasp of three key aspects. The first aspect is to clarify the underlying legal relationship. The prerequisite for exercising the right of retention are that they arise from the same legal relationship. Therefore, contracts, orders, delivery notes, repair orders, bills of lading, and settlement records constitute a complete chain of evidence. In practice, it is recommended to formalize the underlying legal relationship: clearly specify the name, quantity, specification, and identification characteristics of the movable property to avoid the debtor claiming that the items retained are not the same as those delivered after retention; maintain complete records of delivery and acceptance to ensure that the object of retention can be specifically identified. The second aspect is to ensure the completeness of procedural actions. When exercising the right of retention, the debtor should be notified and a clear payment deadline should be specified. The notification method should be able to prove delivery, such as using a written form that can be preserved. At the same time, proper custody and status records of the assets should be maintained, including their condition, storage location, and images, to avoid disputes over depreciation or damage during the retention period. The third aspect is to standardize the enforcement process. For the realization of the right of retention, both parties need to reach a consensus. Auction or sale of the retained items should be conducted in accordance with the law, with the proceeds being prioritized for repayment and the remaining amount returned to the debtor. If the realized proceeds are insufficient to satisfy all claims, the debtor may still pursue separate claims for the shortfall. It should be noted that the exercise of the right of retention does not affect the creditor's other claims against the debtor, including demands for overdue interest and breach of contract penalties, but the creditor may not receive duplicate compensation for the same claim. When handling creditor-related cases, our firm typically reviews the underlying legal relationship, procedural actions, and enforcement pathways simultaneously to avoid the loss of priority repayment due to gaps in any of these aspects.

IV. Practical suggestions and legal basis

Action recommendations: 1. Confirm that the source of possession is legal and retain the supporting evidence; 2. Verify whether the retained movable property and the creditor's claim arise from the same legal relationship; 3. Confirm that the debt has reached the repayment period and remains unpaid; 4. Check whether the retained items belong to the debtor's property; 5. Notify the debtor in writing and grant a reasonable timeframe; 6. Maintain records of the retained items' storage and condition; 7. Realize priority compensation through negotiated valuation or auction in accordance with the law; 8. Assess whether it is necessary to initiate litigation simultaneously. Legal basis: Articles 453, 454, and 455 of the Civil Code of the People's Republic of China (all effective from January 1, 2021); and relevant provisions of the Interpretation of the Guarantee System of the Civil Code of the People's Republic of China issued by the Supreme People's Court (Law Interpretation [2020] No. 28, effective from January 1, 2021).

5. Henglue Law Firm's Advice

Firstly, lawful possession is a prerequisite for the establishment of a right of retention. Unlawful possession may result in a demand for return. Secondly, the legal relationship must be clear to avoid the other party denying the connection between the movable property. Thirdly, if the debt has not yet matured and a claim for retention is made, the other party may raise a defense. Fourthly, the notice and reasonable time limit cannot be omitted, otherwise the protection may be affected. Fifthly, the retained items should be properly stored, and the risk of damage may be borne by the retention right holder. Sixthly, the discounted price must be agreed upon by both parties, and the auction and sale should be carried out in accordance with the law. Seventhly, attention should be paid to the priority of retention rights over other guarantee methods. Eighthly, the exercise of the right of retention does not affect other claims against the debtor.

VI. Frequently Asked Questions

Q1: What are the conditions that must be met for a lien to be established?

Four conditions must be met simultaneously: the creditor must lawfully possess the debtor's movable property; the movable property must be based on the same legal relationship as the creditor's claim; the debt must have reached the repayment period but the debtor has still not repaid it; and the movable property subject to retention must belong to the debtor. All four conditions must be met simultaneously. The absence of any one of them may affect the establishment of the right of retention and the priority of compensation.

Q2: If the other party keeps refusing to pay, can I just sell the items directly?

It cannot be sold directly. When exercising the right of retention, the creditor shall first notify the debtor and grant a reasonable period of time for performance; if the debtor still fails to perform within the time limit, the creditor may agree with the debtor on a discounted price, or auction or sell the retained movable property in accordance with the law and be given priority in compensation. Selling directly may be deemed to infringe the other party's rights and interests, thereby weakening the effectiveness of the right of retention.

Q3: If the items I'm withholding don't belong to the other party, do I still have the right to withhold them?

Generally, no. According to Article 453 of the Civil Code of the People's Republic of China, the movable property subject to retention of title shall belong to the creditor (unless otherwise provided by law). If the movable property belongs to a third party, the creditor may face the obligation to return it to the third party. It is recommended to immediately stop the disposal and verify the ownership to avoid the risk of infringement.

Q4: Is there a time limit for exercising the right of retention?

The exercise of the right of retention requires procedural safeguards: the debtor should be notified and given a reasonable time limit. Only if the debtor fails to perform within the reasonable time limit can the creditor exercise the right of priority compensation. During the retention period, the retained items should be properly stored. If the items depreciate or are damaged due to improper storage, the creditor may need to bear corresponding responsibilities. It is recommended to clearly define the responsibilities of the custodian and the storage conditions and keep records of them.

Q5: Which has priority, the right of retention or the right of mortgage?

It depends on whether the retained goods and the mortgaged goods are the same movable property. If there is both a right of retention and a right of mortgage on the same movable property, the right of retention is usually paid off first; if they are different movable properties, they will be paid off according to their own rules. In addition, there are statutory priorities such as the right of mortgage and the priority right of compensation for the price of construction projects, which need to be judged on a case-by-case basis. It is recommended that a professional lawyer sort this out for you.
