Within thirty days from the abandonment of a lease or concession or from the expiry of a lease, the lessee or grantee shall have priority of registration, by notice of map designation, of a claim in respect of all or part of the land that was subject to the abandoned or expired title. In that case, a claim may be obtained on each part of a lot if the lease or concession covers part of a lot and the holder or grantee does not hold a claim on the other part of the lot.
Within thirty days from the expiry of the time prescribed in the first paragraph, registration under the first paragraph may be applied for by any interested person in respect of any part of the land that has not become subject to a claim pursuant to the first paragraph.
Claims shall subsequently be obtained by staking or map designation according to the territory where the land is situated.
