善意取得是近现代民法物权的一项重要制度,适用善意取得制度须以财产已经交付为要件,占有改定作为一项特殊的动产交付方式是否适用善意取得制度,是理论界争论的问题之一。从善意取得的渊源及构成要件出发可判定占有改定不可以适用善意取得制度。 Since the acquisition of goodwill is an important system of real rights in modern civil law, the application of goodwill acquisition system requires that property has been delivered as an essential part and whether the acquisition of goodwill acquisition system as a special movable property delivery mode is one of the issues debated by theorists . Judging from the origin and components of bona fide acquisition, the system of goodwill acquisition can not be applied to determine the possession of a change of ownership.
