本文指出立法者在决定把约定财产制纳入《婚姻法》的同时应规定一系列配套制度使“约定”明晰,成为一项与不动产登记类似的制度。在交易中由第三人自由查阅,在法律上做合理推定,则可避免第三人与夫妻相互推诿责任时造成审判的困难和“不公”。 This article points out that legislators should stipulate a series of supporting systems to clarify “contract ” and become a system similar to the registration of real estate at the same time of deciding to include the agreed property in the “Marriage Law”. In the transaction, the third party freely consults and legally presumes that the third party and the couple can avoid the difficulty of trial and “injustice” when pushing each other’s responsibilities.
