If a sale of land was never registered, can it still be enforced against a buyer who later purchases the same land in good faith?

Registration is what makes a title effective against outsiders

Article 709 draws a line between the parties to a sale and everyone else. As between the seller and the buyer, an unregistered deed is perfectly valid and binding — the buyer owns the land as far as the seller is concerned. The problem arises with third persons, people who were not part of that original transaction. Because the title was never inscribed or annotated in the Registry of Property, the law says it shall not prejudice them: a stranger to the sale is not bound by a transfer they had no way of discovering.

Why a later buyer in good faith wins

A buyer who checks the registry, finds no annotation of the earlier sale, and pays for the land without knowledge of it is exactly the kind of third person Article 709 protects. That buyer relied on what the public record actually showed, and the earlier, unregistered transaction cannot be used to override that reliance. The first buyer's failure to register is what exposes them to this outcome — the registry exists precisely so that later purchasers can trust it, and an unrecorded sale sitting outside that system does not bind someone who had no reason to know of it.

What this means if you are the earlier, unregistered buyer

If your own purchase was never registered, the risk described by Article 709 runs against you: a later buyer who checks the registry, sees nothing recorded, and buys in good faith can end up with a claim that prevails over yours. Whether that later buyer truly qualifies as acting in good faith is itself a factual question — awareness of your prior claim, obvious signs of someone already occupying the land, and similar circumstances can all affect it. But the safest position is not to rely on an unregistered deed at all and to have the transfer properly recorded.
