Short answer. Yes. Unless the contract shows a contrary intention, the law reads into every sale an implied warranty that the thing is free from hidden faults or defects, or any undeclared charge or encumbrance — alongside an implied warranty that the seller actually has the right to sell it.

What the law says

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.

The warranty exists without being written down

Article 1547 states that in a contract of sale, "unless a contrary intention appears," the law implies certain warranties automatically. Among them is the one this question asks about: "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." A seller does not need to promise this in writing, or say it out loud, for it to apply — the law supplies it as part of the sale unless the parties have shown they intended otherwise.

It is paired with a warranty of the right to sell

The same article also implies a separate warranty that the seller "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." So the buyer gets two automatic protections in the same sale: that the seller actually had the right to sell, and that the thing itself is free from hidden faults, defects, or undeclared burdens.

The warranty covers what was hidden, not what was disclosed

The wording specifically protects against faults, defects, charges, or encumbrances that were "not declared or known to the buyer." A defect the seller openly disclosed, or one the buyer already knew about before the sale, falls outside what this warranty is meant to cover — the article is built around the idea of something hidden from the buyer at the time of the transaction, not every imperfection a thing might have.

Who this warranty does not bind

The article carves out a specific exception: it will not 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." These sellers act under legal authority rather than as the thing's own owner, and the article does not extend the same implied warranty to a sale made in that capacity.
