Property certificate refers to the temporary property certificate in which the ownership of the house has not been determined during the demolition process. As the property right of the house has not been determined, the room type and floor should be determined by lottery when trading. In order to ensure fairness and avoid favoring any party, the relevant departments have stipulated a free transfer policy. There is no need to pay extra fees such as handling fees or taxes when transferring the equity certificate. This design aims to ensure fair and reasonable transactions, reduce the burden on buyers and promote market liquidity and development.
