The manner of acquiring property by a long, honest, and uninterrupted possession or use during the time required by law. The possession must have been possessio longa, continua, et pacifica, nec sit ligitima interruptio - long, continued, peaceable, and without lawful interruption.
The law presumes a grant before the time of legal memory when the party claiming by prescription, or those from whom he holds, have had adverse or uninterrupted possession of the property or rights claimed by prescription. This presumption may be a mere fiction, the commencement of the user being tor-tious; no prescription can, however, be sustained, which is not consistent with such a presumption.
Twenty years uninterrupted user of a way is prima facie evidence of a prescriptive right.The Civil Code Louisiana defines a prescription to be a manner of acquiring property, or of discharging debts, by the effect of time, and under the conditions regulated by law.
The prescription which has the effect to liberate a creditor, is a mere bar which the debtor may oppose to the creditor, who has neglected to exercise his rights, or procured them to be acknowledged during the time prescribed by law. The debtor acquires this right without any act on his part, it resalts entirely from the negligence of the creditor. The prescription does not extinguish the debt, it merely places a bar in the hands of the debtor, which he may use or not at his choice against the creditor. The debtor may therefore abandon this defence, which has been acquired by mere lapse of time, either by paying the debt, or acknowledging it. If he pay it, he cannot recover back the money so paid, and if he acknowledge it, he may be constrained to pay it.
