随着“婚外情”现象在社会生活中的出现和增多，婚外赠与“第三者”财产纠纷也越来越复杂，我国现行法律和司法解释对此类纠纷如何处理的相关规定尚不明确，各裁判路径的不够规范和完善也导致对无过错方配偶、善意“第三者”等主体的权益保护和救济出现不足。本文希望通过对婚外赠与“第三者”财产纠纷的裁判路径进行研究和完善。

本文第一部分从国内关于婚外赠与“第三者”财产纠纷处理的司法实践入手，对国内有关这一问题的法律法规、司法解释、审判现状等进行了梳理。第二部分在司法现状的基础上，对现有裁判路径中每一环节存在的争议问题进行分析：首先是赠与“第三者”财产行为是否构成对公序良俗原则的违反，其次是在赠与“第三者”财产行为被认定无效后请求财产返还的请求权基础，最后是财产返还的份额问题。第三部分在现有法律框架下,结合国外的立法与实践，提出了对现有裁判路径具有针对性的处理或完善意见并予以详细分析：第一，在整个裁判路径中要贯彻对赠与财产的性质进行区分、保护无过错配偶、保护善意“第三者”等裁判理念；第二，针对公序良俗原则的适用建议以无权处分等规则适用为优先，从赠与行为的内容、条件、动机出发，逐步建立合适的判断顺序；第三，明确无效法律行为和不当得利的返还请求权基础为《民法典》第157条和第122条；第四，通过完善婚内对夫妻共同财产的分割、适用“不法原因给付不得返还”，在财产返还份额方面注重对善意“第三者”的保护，通过明确财产权方面的婚内侵权损害赔偿，为无过错配偶提供更全面的救济。

With the emergence and increase of the phenomenon of "extramarital affairs" in social life, the disputes over the gift of "third party" property outside of marriage are becoming more and more complicated.
