Short answer. Yes. Article 1434 provides that when someone who is not yet the owner sells and delivers a thing, and later acquires title to it, that title passes by operation of law to the buyer. You do not need a new sale or a fresh delivery; ownership automatically completes in your favor.
What the law says
When a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee.

Title automatically completes in the buyer's favor
Article 1434 covers a situation that comes up more often than people expect: someone sells and delivers property they do not yet actually own, then later becomes the true owner. The article resolves it cleanly: When a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee. You do not need to go back and redo the sale, or ask the seller to formally re-transfer the property once they finally acquire ownership; the law makes the transfer happen automatically the moment the seller's title is perfected.
Why the delivery already made matters
The rule presupposes that the seller already sold and delivered the thing to you, even without having title at that time. That earlier delivery is what the later-acquired title attaches to. Because you already have the thing, and the seller has now become owner, the law simply lets that ownership flow through to complete what the parties clearly intended from the start, rather than treating the original sale as void or requiring the transaction to be repeated once the seller's title is in order.
Why the law fills this gap automatically
Without this rule, a buyer in your position could be left in an awkward limbo: having paid for and taken possession of the thing, yet technically without valid title, even after the seller becomes the rightful owner, unless the seller voluntarily executed a new transfer. Article 1434 avoids that unfairness and the extra step it would require, by treating the seller's later acquisition of title as automatically curing the earlier defect in ownership, so the sale you already relied on is given its intended legal effect.
What this means for you as the buyer
If you can show that the seller sold and delivered the property to you before actually owning it, and that the seller has since genuinely acquired title, you have a basis to claim that ownership passed to you by operation of law under Article 1434, without needing a fresh deed or a second delivery from the seller to make it complete.
