In short
Where there is more than one debtor or more than one creditor, the Code offers two regimes. In the mancomunada obligation, each debtor is bound only to their part or share in the debt, and each creditor may demand only their part or share in the credit; and the credit or debt is presumed divided into as many parts as there are creditors or debtors. In the solidary obligation the whole performance may be demanded of each debtor, or by each creditor, but only by virtue of what is expressly provided in the obligation or in the law. The solidary creditor may proceed against any of the debtors or against all of them simultaneously, and they cannot raise the benefit of division; claims against one do not bar claims later directed against the others while the debt is not fully collected — though the judgment is enforceable only against the debtor or debtors sued. Whoever performs in full extinguishes the obligation and may claim from the co-debtors only each one’s share, with the interest on the advance, and the insolvency of one is made up by the others pro rata. The creditor may waive solidarity, even tacitly, by demanding or acknowledging payment of one debtor’s share without reservation.
What is it?
It is Section Three of Chapter II of Title I of Book Four of the Civil Code of 2020, Articles 1092 to 1107. It says what happens where the same obligation has several debtors or several creditors: whether each answers for their share or whether any of them can be required to pay the whole.
Who can do it?
Any obligation with more than one debtor or more than one creditor. The solidary regime applies only by virtue of what is expressly provided in the obligation or in the law; failing that, mancomunidad governs.

Step by step
Step 1: The default regime: each one their share
Article 1092 defines mancomunidad: each debtor is bound only to their part or share in the debt, and each creditor may demand only their part or share in the credit. And Article 1093 fills the silence: the credit or the debt is presumed divided into as many parts as there are creditors or debtors.
Step 2: When the debt cannot be split
Article 1094 provides for it: if division is impossible, only the creditors’ collective acts prejudice their right, and the debt can only be made effective by proceeding against all the debtors. And it adds a rule that separates mancomunidad from solidarity: if one of the debtors turns out insolvent, the others are not bound to make up their share.
Step 3: Where solidarity comes from
Article 1096 says it without leaving a gap: by virtue of what is expressly provided in the obligation or in the law, the whole performance may be demanded of each debtor, or by each creditor. Those are the two sources. And Article 1097 clarifies that solidarity may exist even though the creditors and debtors are not bound in the same way nor by the same terms and conditions.
Step 4: Who can be charged, and for how much
Article 1102 is the one that weighs most in practice: the creditor may proceed against any of the solidary debtors or against all of them simultaneously, and they cannot raise the benefit of division. Claims brought against one debtor do not bar those later directed against the others, while the debt is not fully collected. And with an express limit: the judgment entered is enforceable only against the debtor or debtors sued.
Step 5: I paid it all: what can I claim from them
Article 1103 orders it. Full performance by one of the solidary debtors extinguishes the obligation. The one who performs may claim from the co-debtors only each one’s share, with the interest on the advance. And if one of them cannot pay, the default through a solidary debtor’s insolvency is made up by the co-debtors pro rata to each one’s debt. Here insolvency is shared out — the opposite of mancomunidad.
Step 6: Paying one of several creditors
Article 1098 allows it: the debtor may pay any of the solidary creditors, even where sued by only one. But Article 1099 sets the limit on their side: each solidary creditor may do what is useful to the others, but not what is prejudicial, and solidarity does not by itself imply that a solidary co-debtor or co-creditor represents the others.
Step 7: If one settles on their own
Article 1100 reaches it: novation, set-off, remission or compromise of the debt with any of the solidary creditors, or with any of the debtors of that class, extinguishes the obligation totally or partially as to the others; and whoever carried out any of those acts, as well as whoever collects the debt, answers to the others for the share corresponding to them. Article 1101 then details how the co-debtors stand between themselves in each of the four cases, and clarifies that if the acts were limited to one debtor’s share, the others are released only as to that share.
Step 8: Solidarity can be let go
Article 1105 allows it: the creditor may waive solidarity, expressly or tacitly, as to one solidary debtor or as to all. Waiver in favour of one is tacit where the creditor demands or acknowledges payment of their share in the debt without reservation. Waiving as to one does not extinguish the solidary action against the others for the remaining payment; but if the creditor consents to the division of the debt, the waiver benefits all the solidary debtors.
Step 9: If the performance becomes impossible
Article 1106 separates two things. If the performance becomes impossible without the solidary debtors’ fault, the obligation is extinguished. If any of them was at fault, all are solidarily bound for the price; but the damages action arising from the fault may only be directed by the creditor against the debtor at fault. The price is shared; the damages are not.
Step 10: What defences each debtor may use
Article 1107 classifies them: the solidary debtor may use against the creditor’s claims all defences deriving from the nature of the obligation and those personal to them; and of those personal to the others, only as to the part of the debt for which those others are liable.
Step 11: And what happens to prescription
There are two rules and they should not be mixed. Article 1104 says that interruption of the prescription of actions in solidary obligations benefits or prejudices all creditors and debtors equally, except in non-contractual obligations where several caused one damage. And Article 1095 says that in mancomunadas obligations, and in solidary ones arising from co-causation of damage, where the creditor claims from one debtor only the part corresponding to them, prescription is not thereby interrupted as to the other co-debtors.
Where to do it
These rules operate between creditors and debtors; the claim against one, several or all is filed before the Court of First Instance, and the judgment is enforceable only against the debtor or debtors sued. The Code names no agency here.

What to do if something goes wrong
If your question is whether the debt can still be claimed, the guide on the limitation of debts carries the periods. If what you share with others is not a debt but ownership of a thing, see the guide on co-ownership. This guide does not explain what novation, set-off, remission and compromise consist of, which Articles 1100 and 1101 presuppose; nor the general rules on prescription and its interruption; nor the procedural rules for suing one or several debtors: we did not read them here. It also does not cover Articles 1108 to 1113, on divisible and indivisible obligations, which close this chapter. 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
- Taking solidarity for granted: it arises only from what the obligation or the law expressly provides.
- Raising the benefit of division against a solidary creditor: Article 1102 says it does not lie.
- Believing that suing one co-debtor closes the door on suing the others later: it does not, while the debt is not fully collected.
- Enforcing a judgment against a co-debtor who was not sued: it is enforceable only against those sued.
- Claiming the whole from the co-debtors after paying: only each one’s share, with the interest on the advance.
- Applying the solidary insolvency rule to mancomunidad: there the others are not bound to make up the insolvent one’s share.
- Accepting payment of one debtor’s share without reservation: that is a tacit waiver of solidarity as to them.
- Claiming damages from a co-debtor who was not at fault: all answer for the price, but damages are directed only at the one at fault.
Frequently asked questions
Several of us signed — can the whole debt be charged to me alone?
Only if the obligation is solidary, and for that the obligation or the law must say so expressly. If it is, the creditor may proceed against any of the debtors and they cannot raise the benefit of division. If it is not, each answers for their own share.
I paid the whole debt — what can I charge the others?
Each one’s share, with the interest on the advance. And if one turns out insolvent, their default is made up by the co-debtors pro rata to each one’s debt.
What is a mancomunada obligation?
One where each debtor is bound only to their part or share in the debt, and each creditor may demand only their part in the credit. Failing anything else, the credit or debt is presumed divided into as many parts as there are creditors or debtors.
The creditor took my share and said nothing else — do I still answer for the rest?
Under Article 1105, waiver of solidarity in favour of one is tacit where the creditor demands or acknowledges payment of their share in the debt without reservation. That waiver as to one does not extinguish the solidary action against the others for the remaining payment.

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.
Delivering a thing: accessories, expenses and who bears the loss
Whoever must deliver must also preserve, hand over the accessories and pay the delivery expenses. Receiving costs fall on the creditor.
Money debts: what they are paid in and when interest runs
The Code requires payment in the specie agreed and, failing that, in legal tender. It says "legal interest" but sets no rate.
One thing or another is owed: who chooses and when it is fixed
The choice is the debtor’s unless given to someone else, and it only takes effect once notified. Once notified, it stops being alternative.
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.
Co-owned property: how it is managed and how it is divided
A co-owner is not required to remain in the community: they may demand division at any time. And management is decided by quota value, not by headcount.
