《婚姻法》上的收益以“社会财富的增加”为其基本内涵。夫妻一方个人财产婚后的收益具有如下类型——即孳息收益、投资收益、增值收益、生产经营收益。这四类收益具有不同的概念内涵且存在着交叉重叠的关系。而矿山矿石、股票收益、债券收益、知识产权收益的具体性质则需要做具体讨论。本文作者认为,《婚姻法司法解释(三)》第5条将孳息归于个人违背法理且有失公平,应将其限缩解释为“自然孳息”以得出相对合理的裁判结论。 The “Marriage Law” on the proceeds to “social wealth increase ” as its basic connotation. The marital income of a spouse’s husband and wife has the following types of income - that is, yield, investment income, value-added income, production and operation income. These four types of proceeds have different connotations and have overlapping relations. The specific properties of mine ores, stock returns, bond yields, and intellectual property returns need to be discussed in detail. According to the author of this article, Article 5 of the Judicial Interpretation of Marriage Law (III) attributed the fruits of the fruits to the individual’s violation of the law and is unfair and should be narrowed down to be a “natural fruit” to draw a relatively reasonable conclusion.
