Short answer. Not automatically. Legal subrogation is not presumed — the Civil Code allows it only in cases expressly provided by law. Without a specific legal basis or a clear conventional agreement, a third party's payment does not automatically transfer the creditor's rights to that person.
What the law says
Subrogation of a third person in the rights of the creditor is either legal or conventional. The former is not presumed, except in cases expressly mentioned in this Code; the latter must be clearly established in order that it may take effect.

Two kinds of subrogation
Article 1300 of the Civil Code draws a clear line between two types of subrogation: legal and conventional. Legal subrogation arises by operation of law — no agreement is needed, but only where the Code expressly creates it. Conventional subrogation arises from an agreement between the parties, but the article requires that it be clearly established before it takes effect. Both types require more than the bare fact that a third person paid another's debt.
Legal subrogation is not presumed
The article's key phrase is that legal subrogation "is not presumed, except in cases expressly mentioned in this Code." If a stranger walks up and pays your debt out of generosity or in exchange for some private understanding, that act of payment alone does not automatically place the payor in the creditor's position. The Code must specifically say so. This rule prevents third parties from unilaterally acquiring rights against a debtor simply by discharging the obligation — the debtor has an interest in knowing who holds rights against him.
Conventional subrogation must be clearly established
If the parties — the original creditor, the third-party payor, and ideally the debtor — reach an express agreement that the payor will step into the creditor's rights, that is conventional subrogation. But it must be clearly established; no vague understanding or implied arrangement will suffice. In practice, this means the agreement should be documented in a way that leaves no doubt about the parties' intentions. An oral side deal or an informal understanding is likely to fall short of this standard.
What a debtor should know
If someone paid your debt without your involvement and now claims to hold the creditor's rights against you, you can reasonably ask: where does the law expressly create that subrogation, or where is the clear conventional agreement? If neither exists, the payor may have a separate claim — perhaps for reimbursement under rules on payment by a third party — but not necessarily all the remedies and rights of the original creditor. The distinction can affect the remedies available against you, the applicable prescription period, and whether special securities (mortgages, pledges) travel with the transferred rights.
