In short
Subrogation is the transmission of the creditor’s rights to a third party, either by agreement between the two or by virtue of the law, and the credit is transferred to the subrogee with the rights annexed to it, whether against the debtor or against third parties, be they sureties or holders of the mortgages. That is: not only the right to collect passes, but the securities backing it. Yet the Code treats it with suspicion: subrogation of a third party in the creditor’s rights cannot be presumed outside the cases expressly mentioned in this Code, and in the other cases it must be clearly established to produce effect. It is presumed in three situations: in favour of a creditor who pays another preferred creditor; in favour of a third party not interested in the obligation who pays with the debtor’s express or tacit approval; and in favour of the person who pays because they have an interest in performance, save the effects of confusion as to the portion corresponding to them. And it operates by the sole ministry of the law in favour of whoever has made a loan to the debtor to pay, by public deed or private document signed by the interested parties stating that purpose, and in whose receipt the origin of the amount paid is expressed, besides the other cases established by law. If the payment was partial, the original creditor keeps preference for the remainder over the one who subrogated.
What is it?
It is Section Three of Chapter II of Title II of Book Four of the Civil Code of 2020, Articles 1139 to 1143. It governs when whoever pays another’s debt comes to occupy the creditor’s place, credit and securities included.
Who can do it?
Whoever pays another’s debt and fits one of the presumed cases in Article 1141, or the legal subrogation in Article 1142, or has agreed it with the creditor and can establish it clearly.

Step by step
Step 1: What is transmitted
Article 1139 defines it and measures its reach: subrogation is the transmission of the creditor’s rights to a third party, either by agreement between the two or by virtue of the law. And it adds what makes it valuable: the credit is transferred to the subrogee with the rights annexed to it, whether against the debtor or against third parties, be they sureties or holders of the mortgages.
Step 2: It is not presumed: it must be proven
Article 1140 is the warning: subrogation of a third party in the creditor’s rights cannot be presumed outside the cases expressly mentioned in this Code, and in the other cases it must be clearly established to produce effect. Paying, by itself, does not subrogate.
Step 3: The three cases where it is presumed
Article 1141 gives them. In favour of a creditor who pays another preferred creditor. In favour of a third party not interested in the obligation who pays with the debtor’s express or tacit approval. And in favour of the person who pays because they have an interest in performance, save the effects of confusion as to the portion corresponding to them.
Step 4: The loan taken out to pay a debt
Article 1142 is the most practical and the most demanding on paperwork: subrogation operates by the sole ministry of the law in favour of the person who has made a loan to the debtor to pay, by public deed or private document signed by the interested parties in which its purpose is stated, and in whose receipt the origin of the amount paid is expressed. Two documents and two concrete mentions: the purpose in the loan document, and the origin of the money in the receipt.
Step 5: And the other cases the law provides
The same article closes with an open subsection: and in the other cases established by law. Those "other cases" live in other statutes, not in the Code, and we did not read them for this guide: you will not find which they are here.
Step 6: If you only paid part
Article 1143 protects the original creditor: the creditor to whom a partial payment has been made may exercise their right for the remainder with preference over the one who subrogated in their place by virtue of the partial payment of the same credit. Whoever subrogates for a part collects after, not before.
Where to do it
Subrogation is agreed between creditor and third party, or granted by law; no counter concedes it. If its existence is disputed, the Court of First Instance decides. The public document in Article 1142 is executed before a notary, whose rules we did not read here.
How long it takes
What to do if something goes wrong
If you paid another’s debt and only want your money back, that is a different guide: the one on who may pay and who must be paid, which explains what a third party may claim depending on whether they paid with or without the debtor’s consent. If your figure is assignment of the credit rather than payment, this is not the section. This guide names none of the "other cases established by law" in Article 1142(b) because we did not read those statutes; nor do we explain the notarial requirements of a public deed or the mortgage legislation behind the "holders of the mortgages". The Code publishes no fee and no term for these articles. MiPRFácil does not represent anyone in court and gives no legal advice.
Common mistakes
- Assuming that paying another’s debt subrogates you: outside the Code’s cases it must be clearly established.
- Lending money to a debtor to pay without recording the purpose in the loan document.
- Forgetting that the receipt must express the origin of the amount paid.
- Believing subrogation transmits only the right to collect: the annexed rights also pass, against sureties and holders of the mortgages.
- Paying as an uninterested third party without the debtor’s express or tacit approval and expecting the presumption in Article 1141.
- Ignoring the confusion proviso in subsection (c) of Article 1141 as to your own portion.
- Paying part and expecting to collect ahead of the original creditor: they keep preference for the remainder.
- Looking in the Code for the full list of legal subrogations: Article 1142 refers out to other statutes.
Frequently asked questions
I paid another’s debt — do I keep the securities?
Only if there was subrogation. Where there is, the credit is transferred with the annexed rights, whether against the debtor or against third parties, be they sureties or holders of the mortgages. But outside the cases the Code expressly mentions, it must be clearly established.
In which cases is subrogation presumed?
In three, under Article 1141: the creditor who pays another preferred creditor; the uninterested third party who pays with the debtor’s express or tacit approval; and whoever pays because they have an interest in performance, save the effects of confusion as to their portion.
I lent someone money to pay their debt — am I subrogated?
It operates by the sole ministry of the law if the loan is recorded in a public deed or a private document signed by the interested parties stating that purpose, and if the receipt expresses the origin of the amount paid.
I paid only part — do I collect first?
No. Article 1143 gives the original creditor preference for the remainder over whoever subrogated by virtue of the partial payment of the same credit.

Paying for someone else, and paying the wrong person
Anyone may pay another’s debt, with or without permission. But paying someone unauthorized does not always release you.
The creditor will not take payment: releasing yourself by consignment
Four cases open consignment. If the court finds it well made after an unreasonable refusal, it sanctions the creditor up to 5%.
If you owe me and I owe you: when debts cancel themselves out
They are extinguished in the concurring amount, even if neither knows. But five requirements apply, and some debts are excluded.
What an obligation is and where it comes from
Six sources, and the list stays open. Whoever performs knowing they were not bound cannot demand it back.
Putting an asset up as security for a debt: the common rules
The creditor may not keep the asset outside an execution, and any agreement saying otherwise is null and treated as unwritten.
What the Civil Code says about the mortgage
Without recording in the Registry it is not validly constituted, unless the law recognizes it as tacit. The rest is governed by registry law.
