quieting of titl​e is essentially a common law remedy grounded on equity. The competent court is tasked to determine the respective rights of the complainant and other claimants, not only to put things in their proper place, to make the one who has no rights to said immovable respect and not disturb the other, but also for the benefit of both, so that he who has the right would see every cloud of doubt over the property dissipated, and he could afterwards without fear introduce the improvements he may desire, to use, and even to abuse the property as he deems best. But "for an action to quiet title to prosper, two indispensable requisites must concur, namely: (1) the plaintiff or complainant has a legal or an equitable title to or interest in the real property subject of the action; and (2) the deed, claim, encumbrance, or proceeding claimed to be casting cloud on his title must be shown to be in fact invalid or inoperative despite its prima faci​e appearance of validity or legal efficacy."
