This book takes the Proposal on Formulating the Immovable Property Registration Law (No.229) and the proposed Draft Immovable Property Registration Law submitted by Professor Sun Xianzhong at the third session of the 14th National People's Congress as the core content, and systematically expounds the necessity of formulating a special immovable property registration law in China, and related legislative principles and institutional conceptions. The book analyzes in detail the transitional characteristics of the current Interim Regulations on Real Estate Registration and its shortcomings in implementing the real estate property right system of the Civil Code, and demonstrates the important role of improving the real estate registration rules through special legislation in safeguarding the market economy and people's rights. The book contains the legislative proposal, the proposed draft legislation and supporting explanations, as well as related research papers as theoretical reference, which provide systematic legislative suggestions and academic support for the improvement of China's real estate registration legal system.
