摘要
民事法律行为效力瑕疵的认定与处理是民法理论与实践中至关重要的议题，随着市场经济的发展和交易活动的日益复杂，各类民事法律行为不断涌现，其中存在的效力瑕疵问题也愈发凸显，准确地认定与处理民事法律行为效力瑕疵成为维护交易安全、保障当事人权益的关键。本研究旨在深入剖析民事法律行为效力瑕疵的类型、成因及其认定标准，并探索有效的处理方式。通过文献研究法梳理国内外相关研究成果，归纳总结既有理论；运用案例分析法对大量司法实践中的典型案例进行剖析，提炼出不同类型效力瑕疵的表现形式及裁判规则；同时借助比较研究法借鉴国外先进立法经验。研究发现民事法律行为效力瑕疵主要包括意思表示不真实、违反法律法规强制性规定等类型，其背后存在多种复杂的成因，如信息不对称、制度漏洞等。在认定方面应构建多元化的考量因素体系，包括当事人的主观状态、行为的社会影响等，在处理上要遵循平衡保护原则，既要保护善意相对人又要兼顾过错方利益。本研究创新性地提出从多维度构建认定标准以及强调平衡保护的处理原则，为完善我国民事法律行为效力瑕疵相关制度提供了新的思路，有助于提高司法裁判的公正性和准确性，促进民事法律关系的稳定和谐发展。

Abstract
The identification and handling of defects in the validity of civil legal acts are crucial issues in both civil law theory and practice. As the market economy develops and transaction activities become increasingly complex, various types of civil legal acts continue to emerge, highlighting the issue of validity defects. Accurately identifying and addressing these defects is essential for maintaining transactional security and protecting the rights and interests of parties involved. This study aims to thoroughly analyze the types, causes, and criteria for identifying validity defects in civil legal acts, while exploring effective methods for their resolution. By employing literature review, it systematically examines relevant research findings both domestically and internationally, summarizing existing theories. Through case analysis, it dissects numerous typical cases from judicial practices, extracting manifestations and adjudication rules of different types of validity defects. Comparative studies are also utilized to draw upon advanced legislative experiences from abroad. The research finds that validity defects in civil legal acts primarily include issues such as lack of genuine ex pression of intent and violations of mandatory legal provisions, with underlying causes being multifaceted, including information asymmetry and institutional loopholes. In terms of identification, a diversified evaluation system should be established, considering factors such as the subjective state of the parties and the social impact of the act. For handling, the principle of balanced protection should be followed, safeguarding both the interests of innocent third parties and those at fault. Innovatively, this study proposes a multidimensional approach to establishing identification criteria and emphasizes the principle of balanced protection, offering new perspectives for improving China’s legal fr amework concerning validity defects in civil legal acts. This contributes to enhancing the fairness and accuracy of judicial decisions and promotes the stable and harmonious development of civil legal relationships.
