摘要：同居行为在我国已经普遍出现，特别是在年轻人群体中，未婚同居受到年轻人的欢迎。但是同居行为同时也给社会带来了很多伦理问题，特别是挑战了传统的婚姻家庭观念。因此很多学者纷纷呼吁国家应该加强对同居行为的民事立法。由于同居行为确实可能会造成一些社会问题，但是同居行为本身属于私生活范畴，因此国家不能过度干预。同居的双方之间彼此都是独立的、平等的，不存在人身关系，但是同居行为可能会产生双方在财产方面的一些联系，此外，同居关系也会产生亲子关系。本文的观点是，国家可以对同居行为进行立法规范，但是要把握好度，不能侵犯了人们对生活方式的选择。所规范的内容主要是同居双方的财产关系以及由同居而产生的亲子关系，我国可以考虑在婚姻法中补充相关条文的立法方式，吸纳对同居的立法规范。关键词：同居 立法 财产关系 亲子关系Abstract: Unmarried cohabitation is popular in China these years, especially in the young group.
