Because there is no house property certificate, only the house purchase contract cannot be renamed, because it has been filed with the Housing Authority, and the house property certificate will still be issued in the name of the original owner.
 In general, the renaming of the property ownership certificate is mainly divided into direct addition and donation:
 1. Add directly:
 The spouse's name can be added directly during the marriage. If the property belongs to the joint property of the husband and wife during the marriage, even if only one person's name is written on the property certificate, it is also the joint property of two people.
 Therefore, during the marriage period, if such cases need to go through the procedures for adding the name of the property certificate, just bring the marriage certificate, the two housing certificates, the original and copy of the ID card to the "change registration" window of the property transaction center.
 2. Gift:
 The scope of gift includes non marital period, relatives and friends. That is, children, parents and other relatives or friends can be given as gifts on the property certificate.
