Benevolent Acquisition is a means of judging the ownership of moveable property. When applied, it is able to judge the proprietary rights of the third party acting in good faith. The real possessor has no right to recover originals from the third party but to claim for damages on the defaulter one. Therefore, gains and losses concerned with the real possessor and the third party are decided on the application of Benevolent Acquisition. One needs to have a good command of its requisites in order to judge when and what requisites it is applied on. It is obviously a good way to apply Benevolent Acquisition to inducing its requisites into a logically judged chain through analyzing and summarizing the cases in judicial tests and other typical cases.
