1. Where is the property mortgage registration? The legal procedures for real estate transfer or change are stipulated, that is, first apply for real estate change registration, and then apply for land use right change registration with the changed house ownership certificate; The Urban Real Estate Management Law stipulates that a written mortgage contract shall be signed for real estate mortgage and mortgage registration shall be handled. According to the Property Law, the mortgage is established at the time of registration. If the real estate mortgage is not registered, the mortgage right will not take effect; As mortgage is another right set in the subordinate property right-security property right, that is, restricted property right, its main function is to restrict the mortgagor's right to dispose of mortgaged real estate. Without the consent of the mortgagee, the mortgaged property shall not be transferred or leased, so as to avoid the guarantee. Therefore, the registration authority can only appoint from the real estate transaction ownership registration authority and cannot entrust other departments. Collateral has no right of priority. In view of the great differences in land and real estate management systems and diverse management modes in different parts of China, if the law stipulates that buildings such as urban real estate or factories of township (town) and village enterprises are mortgaged, the registration authority shall be stipulated by the people's government at or above the county level.
2. Does the mortgage right disappear when the mortgage registration period expires? In fact, the mortgage registration is still valid after the performance period of the secured debt, which does not affect the validity of the mortgage right. The bank still enjoys the mortgage right to the collateral, and can enjoy the priority of compensation for the auction and sale of the discounted amount of the collateral. According to Article 12 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of the Guarantee Law of People's Republic of China (PRC), "the guarantee period agreed by the parties or required by the registration department is not legally binding on the existence of the security interest. After the limitation of action for creditor's rights secured by security interests ends, the people's court shall support the guarantor's exercise of security interests within two years after the limitation of action ends.
