1. Computer enquiry in the lobby of the Housing Authority. All parties to the house property right can bring their own identification information (notarized power of attorney is required for others to inquire) and apply for inquiry in the lobby of the Housing Authority by using the microcomputer system. At present, housing property rights are basically registered by electronic files.
2. Check the archives of the Housing Authority. All parties to the property right can bring their own identification materials (notarized power of attorney is required for others to inquire) to the archives of the Housing Authority. In recent years, due to the replacement process of real estate licenses, some old real estate licenses need to find the original registration files.
