当前学理上对无权处分行为的分类存在不严密之处。以处分人对标的物是否享有所有权及其状态如何为标准,可将无权处分行为分为不享有所有权、不享有完整所有权和所有权中的处分权受到限制等几种情形。部分共有人擅自处分共有财产是无权处分行为,抵押人擅自处分抵押财产不属于无权处分行为。 At present, the academic classification of the right to disposition is not tight. To punish the subject matter of the subject matter of ownership and status as a standard, can be dismissed as non-right to non-ownership of property rights, is not entitled to full ownership and ownership of the disqualification in several cases. Some of the joint owners have no right to dispose of joint property without authorization, and the mortgagor’s unauthorized disposition of the mortgaged property does not belong to no right to dispose of.
