505. A servitude ceases when the things subject thereto are in such a condition that it can no longer be exercised.
506. It revives if the things be restored in such a manner that it may be used again, even after the time of prescription.
507. Every servitude is extinguished, when the land to which it is due and that which owes it are united in the same person by right of ownership.
508. Servitudes are extinguished by non-user during 30 years, between persons of full age and not privileged.
509. The 30 years commence to run for discontinuous servitudes from the day on which they cease to be used, and for continuous servitudes from the day on which any act is done preventing their exercise.
510. The manner of exercising a servitude may be prescribed like the servitude itself and in the same way.
511. If the land in favour of which the servitude is established belong to several persons in undivided shares, the enjoyment by one hinders the prescription with regard to the others.
512. If among the co-proprietors there be one against whom prescription cannot run, such as a minor, he preserves the right for all the others.
