Obligations: Joint vs. Solidary

Jul 24, 2025

Overview

This episode covers the distinctions between joint and solidary obligations under the law of obligations, focusing on their definitions, differences, examples, and rules on liability among multiple creditors and debtors.

Individual vs. Collective Obligations

  • Individual obligations involve only one creditor and one debtor with straightforward application of general rules.
  • Collective obligations involve two or more creditors or debtors, requiring special rules for allocation and liability.

Joint Obligations

  • When an obligation is joint, each debtor is liable only for their share, and each creditor may demand only their proportionate share.
  • The credit or debt is presumed to be divided into equal shares unless otherwise agreed.
  • Insolvency of one debtor does not increase liability of others, and demand by one creditor does not affect prescription as to others.
  • In joint indivisible obligations, though performance cannot be divided, each party is still liable or entitled only to their share, and all must act together for performance or collection.
  • Delivery to one creditor does not extinguish the obligation to others if they have not received their shares.

Solidary Obligations

  • A solidary obligation allows any creditor to demand, and any debtor to pay, the entire obligation.
  • Solidarity exists only if expressly declared, required by law, or the nature of the obligation demands it; otherwise, obligations are presumed joint.
  • Solidarity may exist even if parties are bound in different manners, periods, or conditions.

Active and Passive Solidarity

  • Active solidarity: Creditors act as mutual agents, and acts beneficial to the group bind all.
  • Assignment of rights or acts prejudicial to co-creditors requires their consent and may result in liability for damages.
  • Full payment by any debtor to any creditor extinguishes the obligation; the paid creditor must distribute shares to others.
  • Passive solidarity: Each debtor is responsible for the full debt and must claim reimbursement from co-debtors for their shares after payment.
  • If a debtor pays after prescription or illegality, no reimbursement is due from co-debtors.

Defenses in Solidary Obligations

  • Debtors can raise total defenses (payment, prescription) affecting the whole obligation.
  • Personal defenses (minority, insanity) can exempt a debtor entirely or partially.
  • Defenses relating to a debtor's share provide partial exemptions.
  • Defenses personal to others offer partial exemption tied to the co-debtor's share only.

Key Differences and Clarifications

  • Joint/solidary liability refers to the legal tie among parties, while divisibility/indivisibility concerns the nature of the obligation's performance.
  • Indivisibility does not imply solidarity, and vice versa.

Examples and Applications

  • Multiple practical scenarios examined, including allocation of payments, insolvency, and remedies in cases of non-performance or delivery errors.
  • Cases where obligations convert to damages when indivisible obligations cannot be performed.
