Short answer. Yes. Under Article 2154 of the Civil Code, when something is received where there was no right to demand it and it was delivered through mistake, the obligation to return it arises. This is the principle of solutio indebiti — the recipient has no right to keep what you never owed.
What the law says
If something is received when there is no right to demand it, and it was unduly delivered through mistake, the obligation to return it arises.

The two conditions: no right to demand, and mistake
Article 2154 requires two things to be present. First, the recipient must have had no right to demand the payment — meaning no valid debt, no court judgment, no contractual obligation, and no legal basis for claiming that money from you. Second, you must have paid through mistake — you genuinely believed the obligation existed when it did not. Both conditions must be established. If the recipient actually had a valid claim and you simply paid it, there is nothing to recover. If you paid knowing you did not owe it — as a gift, or under pressure but without any mistake — recovery under this article is also unavailable.
What the obligation to return means
Once both conditions are met, Article 2154 says the obligation to return it arises. This is automatic — the recipient does not get to choose whether to return the money. They are obligated by law to give it back. This obligation arises from what the law calls a quasi-contract: not from a formal agreement between the parties, but from the law itself, because allowing the recipient to keep the payment would unjustly enrich them at your expense. The recipient who keeps the money is in effect holding it for you.
Proving your case
To recover under Article 2154, you need to establish that you paid, that no valid obligation existed, and that the payment was made by mistake. Documentary evidence is critical: keep your receipts, bank transfer records, or any confirmation of payment. Then show that no debt was ever owed — no valid contract was signed, no judgment existed, or the amount collected exceeded what was legitimately due. The burden of proving the mistake falls on you as the party claiming recovery, so the stronger and more complete your documentation, the better your position.
What to do when the recipient refuses to return the money
Start with a written demand — clearly identify the payment, the date, the amount, and the reason you believe no obligation existed. Give the recipient a reasonable time to respond and return the funds. If the demand is ignored or refused, you may file a civil action for collection of a sum of money based on solutio indebiti. The prescriptive period for this kind of action is relevant — the right to recover does not last forever, and unreasonable delay in making your claim can result in losing it. Addressing the matter promptly after discovering the error protects your rights.
