The document discusses tenancy exempt from registration (TXR) under Section 213(1) of the National Land Code. TXR refers to a letting of land for a period not exceeding 3 years that is not required to be registered. The document outlines different types of TXR and how a tenant can protect their interest in a TXR by endorsing it on the land title register before the landlord transfers the land. Failure to endorse means the tenant's interest is not binding on future owners.
