The acquisition and change of marital equity have different legal effects due to the application of commercial law and family law, where the former stipulates that the equity is exercised by by the party disclosed in public records and the latter stipulates that both spouses have equal rights to manage common property, and the main difference lies in the judge's verification of the joint ownership subject of the marital equity. From the perspective of adhering to the separation of equity rights and interests, it is clear that both husband and wife share equity property rights and benefits based on the joint property system of husband and wife, and define the time nodes for the changes in personal and property rights contained in equity. This clarifies the exercise and transfer of marital equity, as well as the division of equity in the context of impaired spouse rights, thereby bridging the joint property regime of spouses with the applicable rules of corporate equity systems.
