Short answer. Generally, yes, unless the facts trigger the good-faith exception. Payment by someone lacking capacity to give away what's due is invalid under Article 1239 and can normally be set aside. But Article 1427 carves out natural obligations: if the person voluntarily paid money and the recipient already spent it in good faith, it cannot be recovered.

The General Rule: Capacity Matters
Article 1239 protects the integrity of an obligation to give: payment is only valid if the person paying actually has free disposal of the thing being given and the legal capacity to alienate it. Someone who pays with property they have no right to give away, because they lack capacity, or the thing isn't truly theirs to dispose of, has not made a valid, binding payment under the ordinary rules.
The Natural Obligations Carve-Out
The same article immediately qualifies itself: this invalidity rule applies without prejudice to Article 1427, which governs natural obligations. Natural obligations aren't enforceable through court action, but they authorize the recipient to keep what was voluntarily delivered. Where that carve-out applies, the payment isn't simply undone the way an ordinary invalid payment would be; the law treats the underlying transfer differently because of who received it and what they did with it.
Why the Recipient's Good Faith Matters
The protection under the exception is not automatic, it depends on what happened to what was paid. If the recipient already spent or consumed the money or fungible thing in good faith, believing the payment was theirs to keep, the law will not force them to return it or make them account for something no longer in their hands. The rule protects reasonable reliance on a completed transaction, not a later change of mind by the person who made the payment.
What This Means Practically
If you paid something you technically lacked the capacity to give away, don't assume you can automatically demand it back. Whether recovery is available depends on whether the exception under Article 1427 applies, and on concrete facts: what exactly was paid, whether it was money or a consumable, and whether the other side still has it or already used it up in good faith. Courts will also look at whether the recipient had reason to know the payer lacked capacity, since a recipient who knowingly accepted payment from someone incapable of giving may be held to a stricter standard than one who reasonably believed the transaction was valid. Keeping records of when the payment was made and what became of it afterward can make the difference between recovering the money and being told the exception already closed that door.
