The developer's handling of the property ownership certificate is mainly divided into two links. The first is to handle the "big certificate", that is, initial registration, and the second is to handle the "small certificate", that is, transfer registration.
 The initial registration of ownership is usually completed by the developer first, and then each buyer separately handles the registration of commercial housing sales. The developer must apply for the initial registration unilaterally. When the commercial housing is completed, the developer needs to prepare the registration application, the applicant's identity certificate, the certificate of construction land use right, the certificate that the construction project conforms to the planning, the certificate that the housing has been completed, the housing surveying and mapping report and other materials, and submit them to the ownership registration department, After obtaining the receipt from the housing ownership registration department, the obligation of initial registration and certificate handling is deemed to be completed.
 After the initial registration is completed, the developer and the owner need to jointly submit the transfer registration application, and submit the registration application, the applicant's identity certificate, the housing ownership certificate, the housing sales contract and other materials. The transfer registration for the owner is the registration link after the developer completes the initial registration. In addition, the owner shall pay the deed tax, maintenance fund and other related taxes before handling the transfer registration according to relevant regulations. Finally, get the property ownership certificate as required.
