Article 1547
ART. 1547. In a contract of sale, unless a contrary intention appears, there is: (1) An implied warranty on the part of the seller that he has a right to sell the thing at the time when the ownership is to pass, and that the buyer shall from that time have and enjoy the legal and peaceful possession of the thing; (2) An implied warranty that the thing shall be free from any hidden faults or defects, or any charge or encumbrance not declared or known to the buyer. This article shall not, however, be held to render liable a sheriff, auctioneer, mortgagee, pledgee, or other person professing to sell by virtue of authority in fact or law, for the sale of a thing in which a third person has a legal or equitable interest.
