根据我国《继承法》相关规定,继父母子女之间若形成扶养关系,其相互间即有法定继承权,该规定突破了世界通行的传统基础,将继承权范围拓宽到血亲及配偶之外,除造成对传统继承习俗的背离,在实务中也缺乏一定的可操作性。本文通过分析继父母子女关系的性质,从姻亲关系的角度探讨二者间存在法定继承权的不合理性,主张以适当分得遗产份额代替之。 According to the relevant provisions of China’s “Inheritance Law”, if the relationship between step-parents and children forms an uprooted relationship, they have the legal right of inheritance with each other. This provision has broken through the traditional basis of world access and broadened the scope of inheritance beyond those of blood relatives and spouses. Deviation from traditional inheritance practices lacks certain maneuverability in practice. By analyzing the nature of the relationship between the stepfather and the child, this article explores the irrationality of the statutory succession right between the two in terms of the relationship between the two parents and advocates replacing it with the appropriate share of the inheritance.
