主债权诉讼时效届满对担保物权的影响研究

The Impact of the Expiration of the Statute of Limitations for the Principal Claim on Security Interests

摘要: 我国立法在主债权诉讼时效对担保物权的影响问题上历经演变，《民法典》及相关司法解释虽有所规定，但目前仍存在不足，如“人民法院不予保护”的法律后果不明、非典型担保物权制度空白、动产质权规则存在体系冲突等。“人民法院不予保护”应理解为主债权诉讼时效届满后抵押人获得抗辩权，但抵押权本身并不消灭，这种理解方式更符合诉讼时效的制度设计和担保物权的从属性原则。《民法典担保制度解释》第44条以公示方式为标准，将担保物权分为登记型和非登记型，前者受主债权诉讼时效影响后者则不受，这一分类处理方式引发诸多争议。基于担保物权的从属性、物权公示方法的价值中立性以及权利质权规则的一致性，《民法典》第419条应当类推适用于其他担保物权，统一各类担保物权的时效规则，以确保担保物权体系的逻辑统一。

Abstract: The legislation of China has undergone an evolutionary process regarding the impact of the expiration of the statute of limitations for the principal claim on security interests. Although the Civil Code and relevant judicial interpretations have made corresponding provisions, there are still deficiencies, such as unclear legal consequences of not protected by the people’s court, gaps in the system of non-typical security interests, and systemic conflicts in the rules of chattel pledge rights. The phrase “not protected by the people’s court” should be interpreted as that the mortgagor acquires the right of defense after the expiration of the statute of limitations for the principal claim, while the mortgage right itself does not extinguish. This interpretation is more in line with the institutional design of the statute of limitations and the principle of accessory nature of security interests. Article 44 of the Judicial Interpretation on the Security System of the Civil Code classifies security interests into registered and non-registered types based on the method of public notice, with the former being subject to the statute of limitations for the principal claim and the latter not. This classified approach has aroused considerable controversy. Based on the accessory nature of security interests, the value neutrality of real right public notice methods, and the consistency of pledge right rules, Article 419 of the Civil Code should be analogically applied to other security interests to unify the limitation rules of various security interests and ensure the logical consistency of the security interest system.
