P.R. Laws tit. 31, § 1681
Servitudes are extinguished:
(1) By merger in the same person of the ownership of the servient and dominant tenements.
(2) By nonuse for twenty years.
In discontinuous servitudes, this period shall begin to be reckoned from the day on which they have ceased to be used; and with regard to continuous servitudes, from the day on which an act in contravention thereof may have taken place.
(3) When the tenements become in such condition that the servitude cannot be made use of; but the same shall revive if subsequently the condition of the tenements permits it to be used, unless when the use becomes possible, sufficient time for prescription has elapsed, in accordance with the provisions of the preceding number.
(4) When the day matures, or when the condition is fulfilled, if the servitudes be temporary or conditional.
(5) By the renunciation of the owner of the dominant tenement.
(6) By the redemption agreed upon between the owners of the dominant and servient tenements.
