However, according to the process or state of the purchase contract, the procedure or complexity of renaming is different. For example,

1. Only signed the initial contract of the house purchase contract with the real estate developer, and only needed to communicate and negotiate with the developer to sign a separate house purchase contract;

2. If you have gone through the online signing procedures and filed with the Housing Authority, you should go to the Housing Authority to cancel the original contract for filing, and then re-sign the contract with the developer.
