Under the background of rural revitalisation, the residential land is gradually changing from “separation of two rights” to “separation of three rights”, and the qualification right has become the key to the “separation of three rights”. By analysing the real situation and regional characteristics of the model, the application of the system of qualification right of the residential base has the dilemma of unclear identification of the subject, incomplete content of the right and registration system, exercise system and relief system. It is necessary to improve the subject of the system from the level of system and practice, improve the content of the right and registration system, and make clear the exercise system and relief system, with a view to promoting the improvement of China’s legal system of the residential base and regulating the legal system of the residential base. In order to promote the improvement of China’s legal system of the residential base, regulate the work of “three rights of separation”, and promote the implementation of the strategy of rural revitalisation.
