After the real estate development project has obtained the pre-sale permit and advance notice registration of commercial housing, the real estate development enterprise shall, within 30 days from the date of signing the commercial housing sales contract with the winning bidder, apply to the real estate transaction management department within the project area for filing the pre-sale contract of commercial housing;

The real estate registration department can handle the house registration formalities within 7 working days according to the complete information provided by the buyers. For those who meet the conditions for contract filing, the real estate registration department shall affix a "special seal for the filing of pre-sale contract of commercial housing" on the commercial housing sales contract (including a full set of electronic versions) to indicate it. Property buyers can check the publicity in the city real estate market information network.
