Distinction from Accion in Rem Verso | Solutio Indebiti | Kinds | QUASI-CONTRACTS

CIVIL LAW > X. QUASI-CONTRACTS > B. KINDS > 2. SOLUTIO INDEBITI > a. DISTINCTION FROM ACCION IN REM VERSO

In Philippine civil law, quasi-contracts are juridical relations arising from lawful, voluntary, and unilateral acts which bind the parties in the absence of a contract, to avoid unjust enrichment. Among the quasi-contracts, solutio indebiti and accion in rem verso are two distinct doctrines, often confused due to their common goal of preventing unjust enrichment. Below is a meticulous analysis of the concepts and their distinctions.


SOLUTIO INDEBITI

Definition:
Under Article 2154 of the Civil Code of the Philippines, solutio indebiti arises when a person, through mistake, pays or delivers something not due, creating an obligation on the part of the recipient to return what has been unduly received.

Essential Elements:

  1. Payment or delivery was made: There must be a transfer of money, property, or value.
  2. The payment or delivery was not due: The obligation did not exist, or if it did, it was not owed to the recipient.
  3. The payment or delivery was made through mistake: The payer must not have intended to make a gratuitous transfer; the transfer must have been unintentional.

Legal Basis and Effects:

  • The recipient of the undue payment is obliged to return what was received (Article 2155).
  • If what was delivered cannot be returned, the recipient must pay its value or compensate for damages.

Illustrative Case Example:
Person A pays Person B a debt, mistakenly believing it is due, when in fact, it has already been paid. Person B has no right to retain the payment and is obliged to return it.


ACCION IN REM VERSO

Definition:
Accion in rem verso is a subsidiary remedy based on the principle of unjust enrichment, whereby a person who enriches themselves to the detriment of another without just or legal ground must indemnify the latter.

Legal Basis:
Derived from the general principle of unjust enrichment codified in Article 22 of the Civil Code, which states:
"Every person who, through an act or performance by another, or any other means, acquires or comes into possession of something at the expense of the latter without just or legal ground, shall return the same to him."

Essential Elements:

  1. Enrichment of one party: A benefit or gain was received.
  2. Impoverishment of another party: A corresponding loss or detriment occurred.
  3. There is no just or legal ground for the enrichment.
  4. There is no other available remedy under the law: It is a remedy of last resort, applicable only when no contractual, quasi-contractual, or other specific remedies are available.
  5. The enrichment and impoverishment must be correlative: The gain must result from the loss of the other.

Illustrative Case Example:
Person A builds a structure on Person B’s land, believing in good faith that the land is theirs. Person B, who becomes enriched by the structure, must compensate Person A under accion in rem verso if no other remedy exists.


DISTINCTIONS BETWEEN SOLUTIO INDEBITI AND ACCION IN REM VERSO

Basis Solutio Indebiti Accion in Rem Verso
Source of Obligation Mistaken payment or delivery of something not due. Unjust enrichment without just or legal ground.
Existence of Mistake Mistake is an essential element. Mistake is not required; enrichment may occur through any means.
Nature of Obligation Specific to the undue delivery of money or goods. Broader application to any instance of unjust enrichment.
Scope Limited to quasi-contractual situations of undue payment. Subsidiary remedy applicable only when no other remedies exist.
Objective To return what was unduly delivered. To recover or compensate for unjust enrichment.
Applicability Arises only from an error in payment or delivery. Applies in all cases of unjust enrichment without other remedies.

JURISPRUDENTIAL GUIDANCE

  1. Solutio indebiti vs. Accion in rem verso as exclusive remedies:

    • Solutio indebiti applies specifically where mistaken payments or deliveries have been made.
    • Accion in rem verso applies only when no other specific remedy, including solutio indebiti, can address the situation.
  2. Requirement of Subsidiarity for Accion in Rem Verso:
    In Central Bank of the Philippines v. CA, the Supreme Court emphasized that accion in rem verso is a remedy of last resort. It cannot be invoked if an alternative remedy is available, such as solutio indebiti, breach of contract, or tort.

  3. Mistake as a Key Element in Solutio Indebiti:
    In Garcia v. Llamas, the Court held that solutio indebiti requires proof that the payment or delivery was made due to error. Without mistake, solutio indebiti does not apply.


CONCLUSION

While both solutio indebiti and accion in rem verso aim to prevent unjust enrichment, they differ in scope, elements, and applicability. Solutio indebiti is narrowly tailored for cases of mistaken payment or delivery, whereas accion in rem verso is a broader subsidiary remedy for any unjust enrichment where no other legal recourse exists. Understanding these distinctions is crucial in determining the appropriate legal remedy in quasi-contractual disputes.
