Short answer. Yes. Article 2163 presumes a mistake when something already paid, or never due at all, is delivered again. The presumption favors you as the payer, but the recipient can still overcome it by proving the second delivery was actually a gift, out of liberality, or made for some other genuine reason.

What the law says

It is presumed that there was a mistake in the payment if something which had never been due or had already been paid was delivered; but he from whom the return is claimed may prove that the delivery was made out of liberality or for any other just cause.

A second payment is presumed to be a mistake

Article 2163 puts the burden in your favor once you can show the debt was already settled. It states: It is presumed that there was a mistake in the payment if something which had never been due or had already been paid was delivered. You do not need to separately prove you were confused, forgot the earlier payment, or acted carelessly; the law starts from the assumption that paying something already paid, or paying something that was never owed at all, happened by mistake, once you establish that the debt had, in fact, already been paid or never existed.

The presumption can be overcome

The recipient of the second payment is not without a defense. The same article allows that he from whom the return is claimed may prove that the delivery was made out of liberality or for any other just cause. If the person who received your second payment can show you actually intended it as a gift, or that there was some other genuine reason for making that payment despite the debt already being settled, the presumption of mistake is rebutted, and you would not be entitled to recover it as an undue payment.

Why the presumption favors the payer

Ordinarily, someone claiming they paid by mistake would have to prove that mistake affirmatively. Article 2163 shifts that burden because paying a debt that is already extinguished, or that never existed, is not something a person ordinarily does on purpose without a special reason. The law treats that pattern of facts as inherently suggestive of error, so it is fairer to make the recipient explain why the payment was not a mistake, rather than forcing the payer to prove a negative.

What this means for recovering your second payment

If you can establish that the debt had already been paid before you paid it again, you are in a strong position to claim the second payment back, because Article 2163's presumption of mistake is already working in your favor. The recipient would then need to come forward with proof that the payment was meant as a gift or was justified for some other genuine reason, rather than you having to prove your own mistake from scratch.
