For commercial housing projects developed and built by real estate development enterprises, the house owner may entrust the original development and construction unit to apply for real estate registration with the real estate registration agency. If the original real estate development enterprise has its business license revoked, or it has been cancelled and there is no successor unit, the house owner or the owners' committee may apply for real estate certificate registration.

The certificate of real estate ownership is the proof that the obligee enjoys the real right of real estate. After the real estate registration agency completes the registration, it will issue the certificate of real estate ownership to the applicant according to law. A party holding a real estate ownership certificate can prove that he is the owner of the property right registered in the real estate ownership certificate. Ownership certificate is a certificate to prove property rights. Ownership certificate can also be used as evidence of the existence of rights, but it is not the main basis for confirming rights. Even if the ownership certificate is transferred to others for possession, if the registered contents have not changed, the property right itself will not change.
