In short
Where someone buys a credit that is already in litigation, the Code gives the debtor a way out that almost nobody knows about: if a litigious credit is assigned, the debtor has the right to extinguish it by reimbursing the assignee what the assignee paid, the costs incurred, and the interest on the payment from the day it was made. They do not pay the whole debt: they pay what it cost to buy it, plus costs and interest. Two more things must be known for that. When a credit counts as litigious: from the moment the complaint is answered, not from when it is filed. And how much time there is: the debtor may invoke their right within the caducidad period of thirty days, counted from when the assignee claims payment from them. That it is a caducidad term matters, because in this same Code caducidad terms are not interrupted or suspended by the parties’ acts. Article 1221 excepts three assignments: one made to a co-heir or co-owner of the assigned right, one made to a creditor in payment of their credit, and one made to the possessor of a property subject to the litigious right being assigned.
What is it?
They are Articles 1220 and 1221 of the Civil Code of 2020, closing the title on the transmission of obligations. They give the debtor of a credit in litigation the right to extinguish it by paying the buyer what it cost them, and set a short period to exercise it.
Who can do it?
The debtor of a credit assigned while litigious, that is, after the complaint was answered. It does not apply to the three assignments Article 1221 excepts.

Step by step
Step 1: The right, in one sentence
Article 1220 grants it thus: if a litigious credit is assigned, the debtor has the right to extinguish it by reimbursing the assignee what the assignee paid, the costs incurred, and the interest on the payment from the day it was made. Note the measure: what the buyer paid, not what they are claiming.
Step 2: Three items, not one
Returning the price is not enough. The article requires what was paid, the costs incurred and the interest on the payment from the day it was made. How much that interest is, this article does not say, and this guide does not invent it.
Step 3: When a credit is litigious
The second paragraph fixes it without margin: a credit is held litigious from the moment the complaint is answered. Filing the complaint is not enough; the answer is needed. If the assignment happened before that moment, this right does not arise.
Step 4: Thirty days, and they are caducidad
The third paragraph sets the clock: the debtor may invoke their right within the caducidad period of thirty days, counted from when the assignee claims payment from them. The Code calling it caducidad is not a detail: in its Articles 1206 to 1209, caducidad terms begin when the law determines and only the law may provide for their interruption or suspension; the parties’ acts do not affect their running.
Step 5: From when they are counted
Not from the assignment nor from when you learned of it: from when the assignee claims payment from you. That is the fact that starts the thirty days, and it is worth having a record of its date.
Step 6: The three excepted assignments
Article 1221 names them: excepted is the assignment made to a co-heir or co-owner of the assigned right; the one made to a creditor in payment of their credit; and the one made to the possessor of a property subject to the litigious right being assigned. In those three cases the debtor cannot extinguish the credit for the assignment price.
Where to do it
The right is invoked against the assignee claiming payment, and if there is a case, before the Court of First Instance hearing it. When a complaint is deemed answered and how costs are taxed is governed by the Rules of Civil Procedure, which we did not read for this guide. The Code names no agency here.

What to do if something goes wrong
If your debt was assigned before the complaint was answered, it is not a litigious credit for these purposes and this right does not apply; the guide for you is the one on the assignment of credits. If what you want to know is whether the debt can still be claimed, see the one on prescription, which also explains the general regime of caducidad. This guide does not say what interest is paid on what the assignee disbursed, because the article does not fix it, nor does it explain the Rules of Civil Procedure behind answering a complaint and taxing costs: we did not read them. The Code publishes no fee and no service term for these articles; the thirty days are a statutory caducidad period. MiPRFácil does not represent anyone in court and gives no legal advice.
Common mistakes
- Counting the thirty days from the assignment: they run from when the assignee claims payment.
- Believing the period can be interrupted by talking to the assignee: it is caducidad, and the parties’ acts do not affect its running.
- Reimbursing only the price: the costs incurred and the interest on the payment from the day it was made must be added.
- Invoking the right for a credit assigned before the complaint was answered: it was not yet litigious.
- Counting from the filing of the complaint instead of from its answer.
- Trying it against a co-heir or co-owner of the assigned right.
- Trying it where the assignment was made to a creditor in payment of their own credit.
- Trying it against the possessor of a property subject to the assigned litigious right.
Frequently asked questions
They bought my debt cheap — can I pay only that?
If the credit was litigious when assigned, yes: Article 1220 lets you extinguish it by reimbursing the assignee what they paid, the costs incurred, and the interest on the payment from the day it was made.
From when is a credit considered litigious?
From the moment the complaint is answered. Not from when it is filed.
How much time do I have?
Thirty days, counted from when the assignee claims payment from you. And they are caducidad: they are not interrupted or suspended by the parties’ acts.
Are there cases where I cannot do it?
Three, under Article 1221: where the assignment was made to a co-heir or co-owner of the assigned right, to a creditor in payment of their credit, or to the possessor of a property subject to the litigious right being assigned.

If you paid the old creditor before learning of the assignment, you are released. And the assignment carries all accessory rights.
Prescription: how long they can collect from you or sue you
Personal actions prescribe in 4 years and damages in 1 year from learning who caused them. Acknowledging the debt restarts the clock.

Keeping the thing until you are paid: the right of retention
No court permission is needed to retain, but the retainer may not use the thing or keep it: any agreement otherwise is void.
