In short
The Code separates two questions. Who may pay: any person may make the payment, whether or not they have an interest in performance, and whether the debtor knows and approves of it or is unaware; whoever pays on another’s account may claim from the debtor what they paid, except where they did so without the debtor’s consent, and in that case, if the third party pays in good faith, they may require the debtor to restore what the payment was useful for. Whoever pays in the debtor’s name without the debtor’s knowledge cannot compel the creditor to subrogate them in their rights. In obligations to give, payment by someone lacking free disposal of the thing or capacity to alienate it is not valid, although if it was money or a fungible thing they cannot claim back what the creditor spent or consumed in good faith. And who must be paid: the person in whose favour the obligation was constituted, or another authorized by the creditor, the law or the court. Payment to the creditor is not valid if they are incapacitated to administer their property — except to the extent it was useful to them — nor if made after the debtor has been judicially ordered to suspend payment. By contrast, payment made in good faith to whoever appears to be the owner of the credit does release the debtor.
What is it?
They are Sections Three and Four of Chapter I of Title II of Book Four of the Civil Code of 2020, Articles 1120 to 1125. They answer the two identity questions of payment: whose hand it may come from and whose hand it must land in.
Who can do it?
Anyone paying their own or another’s debt, and any creditor or representative receiving a payment. In obligations to give, whoever pays also needs free disposal of the thing and capacity to alienate it.

Step by step
Step 1: Anyone may pay
Article 1120 opens wide: any person may make the payment, whether or not they have an interest in performance, and whether the debtor knows and approves of it or is unaware. The creditor cannot refuse a payment merely because it comes from a third party.
Step 2: What they may then claim from the debtor
The same article separates two cases. If they paid with the debtor’s consent, they may claim what they paid. If without it, they may not: only, and only if they paid in good faith, may they require the debtor to restore what the payment was useful for. The gap between what was paid and what was useful can be wide.
Step 3: Paying does not put you in the creditor’s place
Article 1121 cuts it off: whoever pays in the debtor’s name, without the debtor’s knowledge, cannot compel the creditor to subrogate them in their rights. Subrogation is agreed or granted by law; it is not earned by the bare act of paying behind someone’s back.
Step 4: You cannot pay with what is not yours
Article 1122 applies to obligations to give: payment made by someone lacking free disposal of the thing owed or capacity to alienate it is not valid. But it limits the clawback: if the payment consisted of a sum of money or a fungible thing, they cannot claim back from the creditor what the creditor spent or consumed in good faith.
Step 5: Who must be paid
Article 1123 sets the rule: for payment to be valid, it must be made to the person in whose favour the obligation was constituted or to another authorized by the creditor, the law or the court to receive it in their name. Three sources of authorization, and none is presumed.
Step 6: Two cases where paying the creditor is not enough
Article 1124 names them. Payment to the creditor is not valid if they are a person incapacitated to administer their property, except to the extent it was useful to them. Nor if it is made after the debtor has been judicially ordered to suspend payment. Paying against a court order does not release you.
Step 7: And one where paying the wrong person is enough
Article 1125 protects the diligent debtor: payment made in good faith to whoever appears to be the owner of the credit releases the debtor, even if it is later learned the credit did not belong to them. And it adds two more rescues: payment to a third party is also valid in so far as it was useful to the creditor, or where the creditor ratifies it.
Step 8: If the debt sits in a note or a cheque
The last paragraph of Article 1125 steps outside the Code: the validity and effects of payment of an obligation incorporated in a negotiable instrument are governed by the special legislation. We did not read that legislation for this guide, so you will not find those rules here.
Where to do it
These are rules between the parties and the third party who pays; where the validity of a payment is disputed, the Court of First Instance decides. The judicial order suspending payment that Article 1124 mentions also comes from the court. The Code names no agency here.
How long it takes
What to do if something goes wrong
If what you want is to step into the creditor’s place after paying, that is subrogation and it lives in the next chapter of the Code, with the substitutes for payment: this guide does not cover it. If your question is when or where to pay, see the guide on the term and place of payment; if it is whether instalments can be imposed on you, the one on the requirements of payment. This guide does not explain the negotiable-instruments legislation Article 1125 defers to, nor the procedural rules for the suspension order in Article 1124: we did not read them. 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
- Refusing a third party’s payment: any person may make it, with or without an interest in performance.
- Paying another’s debt without their consent and expecting everything back: you can only demand what it was useful for.
- Believing that paying subrogates you: whoever pays without the debtor’s knowledge cannot compel the creditor to subrogate them.
- Handing over in payment a thing you have neither free disposal of nor capacity to alienate.
- Paying an employee or relative of the creditor without authorization from the creditor, the law or the court.
- Paying after a judicial order suspending payment: that payment is not valid.
- Paying a person incapacitated to administer their property and assuming it counts: it is valid only to the extent it was useful to them.
- Looking in the Code for the effects of payment by negotiable instrument: it sends them to the special legislation.
Frequently asked questions
I paid a relative’s debt — can I collect it from them?
If you paid with their consent, you may claim what you paid. If it was without their consent and you paid in good faith, you may only require them to restore what the payment was useful for.
I paid someone who turned out not to own the debt — do I pay again?
If you paid in good faith to whoever appeared to be the owner of the credit, Article 1125 releases you even if it is later learned the credit did not belong to them.
Can a third party pay without the debtor knowing?
Yes. Article 1120 allows it even where the debtor is unaware. What that third party cannot do is compel the creditor to subrogate them in their rights.
Whom must I pay to be released?
To the person in whose favour the obligation was constituted, or to another authorized by the creditor, the law or the court to receive it in their name.

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.
No date and no place agreed: when and where performance is due
With no term, payment is due at once unless the deal implies a tacit one. With no place, the municipality where the debtor resides.
No one has to accept part payment or a different thing
The obligation is extinguished when what is owed is delivered in full. The creditor cannot be compelled to take part, or something else.
Several debts with one creditor: which one your payment goes to
You choose at the moment of paying, but interest comes first. And a receipt for principal with no reservation presumes interest paid.
Several debtors: when each pays a share and when one is charged the lot
Solidarity is not presumed: the obligation or the law must say so. Without it, the debt is presumed divided into equal parts.
Debt collection agencies: the 15 practices the law forbids them
Act 143-1968 licenses collection agencies and forbids fifteen practices, from threatening violence to charging additional fees never agreed to.
