摘要:2001年《婚姻法》明确规定了夫妻应该互相忠实的基本原则。“夫妻忠实义务”几乎作为一条倡导性条款订入新婚姻法中，在总则中予以体现，反映了主流民意和法学界的共识。但是在实践性上看，基本无可操作性，既没有具体的法律条例也没有确定夫妻忠实义务中关于人身财产关系的规定，更没有违反忠实义务后的损害赔偿制度，导致原则形同虚设。笔者将在现行已有的相关规定外，探讨完善相应的法律规定，主要从夫妻忠实义务的内涵，违背夫妻忠实义务的类型，实践中运行的障碍，借鉴夫妻忠实义务在国外的立法经验，对我国构建明确完善的夫妻忠实义务制度提出具体的若干建议。

Abstract:In 2001, the Law of Marriage explicitly points out the basic principle that the husband and wife should be faithful to each other. “The duty of loyalty by husband and wife” was put into the new marriage law as an advocate provision, which reflects the consensus of the mainstream of public opinion and the legal community. However, in practical point of view, it is not operational. It does not have not specific legal rules nor does it determine the couple’s duty of loyalty on the personal and property relations. And it has no systems of damages for breaching the duty of loyalty, resulting in vain. The author explores the existing provisions to improve relevant legal requirements, and gives recommendations to improve the system of couples’ duty of loyalty in China, from the connotation of the matrimonial duty of loyalty, the modes of breaching the duty of loyalty, the obstacle in the practice, and the legislative experience in foreign countries.

男女因结婚而成为夫妻，双方之间基于婚姻的法律效力，便产生了权利与义务的关系。婚姻法中关于夫妻之间的忠实义务并无详细规定，只有原则性条款，也基本无实际可操作性，这不仅关系到婚姻法上关于这一篇章的缺失，也时刻影响着现代婚姻家庭的和谐稳定。夫妻忠实义务在学界有广义与狭义之分，狭义的忠实义务也称为贞操义务、不为婚外性生活义务，它通常指夫妻不为婚姻外之性交，在性生活上互守贞操，保持专一。广义上的忠实义务还包括不得恶意遗弃配偶对方，以及不得为第三人的利益而牺牲、损害配偶他方的利益。笔者认为夫妻忠实义务不能只关乎于两性之间，更要贴合当代社会的状况，考虑到第三人介入损害配偶利益的状况日益增多，为了更好的维护被违反忠实义务方的利益，因此要从广义上来看待夫妻的忠实义务。
