The audit of the real estate administrative department will review the marital status of family members at the time of their own property rights housing, house transfer, household registration and house purchase registration (if the husband and wife are divorced, the divorce period should also be verified). After examination, those who have the priority to choose houses by lottery can only import the information of buyers who need to register into the lottery system.
After the qualification examination of the general process of purchasing a house, the database of eligible purchasing families shall be engraved and sealed. Before the lottery: the development enterprise randomly informs some families who buy houses as representatives to supervise the lottery. When shaking the number: the notary checks the sealed state of the special computer and CD-ROM, draws lots to select 6 people from the family representatives who buy the house, draws the seed number publicly, inputs it into the computer, and starts to shake the number. The completion of the lottery: the notary publicized the lottery results on the spot, burned the CD, read the notarial certificate, and sealed the computer and the result CD.
