Registration/备案 is not ownership transfer — it is an admin perfection step that local practice may expect.
Many cities expect residential or commercial lease filing/registration with housing authorities. Effects against bona fide third parties and for school/permit workflows can depend on filing. This wiki orients registration. It does not replace title registration for sales. Commercial and residential lease pages explain the underlying contract. Deposits remain a contract money issue.
