Adopting registration as one way to acquire, and publicize, a residential tenant's priority against third parties and right to preferential repayment would bring further benefits. First, it would lighten the burden on the parties concerned with those rights. Registration would not reduce what the tenant has to spend compared with the current method, but it would let the tenant avoid the risk of getting no protection at all when the house is sold or auctioned because of a wrong lot number or some small mistake. Potential interested persons, such as someone buying the house, currently have to check who occupies it, inspect the resident registration, check the fixed-date records at the issuing office and, if needed, compare the land register with the resident registration to reach a legal judgment. A registration system would spare them this effort and risk.

It would also sharply reduce the social costs surrounding residential leases. Clear publicity of tenants' priority and preferential repayment rights would prevent needless disputes in advance. If the same registration method were adopted for commercial leases, disputed cases could be resolved without difficulty, for example a building in which a tenant gained protection under the Housing Lease Protection Act and then, with the landlord's consent, converted it for business use and tried to register a business, or an officetel listed in public records as an office or neighborhood facility but used as a home.

In principle, a lease right is a personal claim and cannot be asserted against anyone other than the landlord. But because the lease right serves to secure housing for ordinary people, the Civil Code and the Housing Lease Protection Act give it property-like effect under certain conditions to protect the tenant. The ways to give it that effect include using a registered jeonse right or a mortgage under the Civil Code, and securing priority and preferential repayment under the Housing Lease Protection Act by registering a move-in and obtaining a fixed-date stamp.

To add: the guaranteed lease term, left as a heading only in the paper, is set by Article 4 of the Housing Lease Protection Act. A lease with no term or a term under two years is treated as two years, and since July 31, 2020 Article 6-3 lets the tenant request one renewal for two more years, with rent increases capped at 5%. A tenant who must move out without getting the deposit back can ask the court for a lease registration order after the lease ends and keep priority and preferential repayment (Article 3-3). For commercial leases, the renewal request can be used for up to ten years.
