Why we must publish the lease?

Publication by the lessee of the lease in the land register against the building will turn out to be particularly useful if there is a sale of the property. An unpublished lease cannot be opposable against the new owner and if such was the case, the latter could terminate the lease and so ensure the eviction of the lessee. Every lessee has thus an interest to publish his lease not to be unduly dispossessed of the leased premises especially if leasehold improvements were made.
