QUASI-CONTRACTS

CIVIL LAW: QUASI-CONTRACTS (Philippines)

Quasi-contracts fall under Chapter 1, Title XVII, Book IV of the Civil Code of the Philippines. They are juridical relations that arise not from agreements (contracts) but by virtue of lawful, voluntary, and unilateral acts that bind the parties to obligations to each other. Their legal basis is Articles 2142 to 2175 of the Civil Code. Below is a meticulous breakdown of everything relevant to quasi-contracts.


1. Definition

  • Article 2142: Quasi-contracts are those juridical relations that arise when a person, without any agreement, becomes obligated to another because of a lawful and voluntary act, and thereby binds the former to the latter.

2. Basis

Quasi-contracts are founded on the principle of equity and justice: "No one shall unjustly enrich himself at the expense of another." This principle ensures that benefits conferred without proper cause do not result in one party's unjust enrichment.


3. Kinds of Quasi-Contracts

The Civil Code identifies two primary kinds of quasi-contracts:

a. Negotiorum Gestio (Management of the Affairs of Another)

  • Articles 2144 to 2153.
  • Occurs when a person voluntarily takes charge of the agency or management of another's business or property without the latter's authority.
  • Key Points:
    • The gestor (manager) must act with the diligence of a good father of a family.
    • The gestor may recover necessary and useful expenses incurred in good faith.
    • The owner must indemnify the gestor for obligations he may have incurred in good faith.
    • Gestor is liable for damages if negligence or fraud occurs.

b. Solutio Indebiti (Payment by Mistake)

  • Articles 2154 to 2160.
  • Occurs when someone receives something not due to them and is obligated to return it.
  • Key Points:
    • A person who has unduly received payment is obliged to return it.
    • If the recipient acted in bad faith (i.e., knew the payment was not due), they must return the payment and indemnify for damages.
    • If the thing unduly paid is consumed or lost, the recipient in good faith is liable only for its value.
    • The payer must prove that payment was made by mistake.

4. Other Quasi-Contracts

The Civil Code also recognizes other obligations arising from quasi-contracts, not expressly categorized as negotiorum gestio or solutio indebiti. For instance:

a. Obligations Related to Common Property

  • Article 2158: Co-owners or common possessors are bound to contribute proportionately to necessary expenses.

b. Unjust Enrichment

  • The general principle prohibiting unjust enrichment (Article 22 of the Civil Code) supplements quasi-contracts:
    • "Every person who, through an act of 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."

5. Characteristics of Quasi-Contracts

  • Lawful Act: The act giving rise to the quasi-contract is lawful, unlike acts giving rise to delicts or quasi-delicts.
  • Voluntary Act: The obligation arises from a voluntary action, but no formal agreement exists between the parties.
  • Unilateral: It imposes an obligation on one party without the need for mutual consent.

6. Comparison with Related Concepts

  • Quasi-Contract vs. Contract:
    • Contracts arise from mutual consent; quasi-contracts arise from lawful, unilateral acts.
  • Quasi-Contract vs. Delict/Quasi-Delict:
    • Delicts and quasi-delicts involve unlawful or wrongful acts; quasi-contracts are based on lawful acts.
  • Quasi-Contract vs. Natural Obligations:
    • Natural obligations do not grant a right of action to enforce performance, while quasi-contracts create enforceable rights and obligations.

7. Duties and Rights of Parties in Quasi-Contracts

Duties of the Party Conferring a Benefit:

  • Act in good faith.
  • Exercise diligence in the act, especially in negotiorum gestio.

Duties of the Recipient:

  • Return the benefit or compensate for its value.
  • Reimburse necessary and useful expenses incurred in good faith.
  • Indemnify for damages caused by wrongful retention of benefits.

8. Liability Under Quasi-Contracts

Liability depends on the presence of good faith or bad faith:

  • Good Faith:
    • Obligation limited to what was received or its equivalent value.
    • No indemnity for incidental losses.
  • Bad Faith:
    • Liability extends to restitution, interest, damages, and any resulting losses.

9. Examples of Quasi-Contracts in Philippine Jurisprudence

a. Negotiorum Gestio

  • Case: A neighbor voluntarily repairs the leaking roof of a property owner's house to prevent water damage. The owner must reimburse the expenses incurred if the gestor acted in good faith.

b. Solutio Indebiti

  • Case: A company accidentally pays an employee twice for the same period. The employee is obligated to return the excess payment.

c. Unjust Enrichment

  • Case: A property owner constructs a fence that inadvertently improves the neighboring lot. The neighbor benefits and must compensate if the improvement was substantial.

10. Key Doctrines and Principles

  • Equity: Quasi-contracts emphasize fairness, ensuring that no one benefits at the expense of another without justification.
  • Prevention of Unjust Enrichment: Quasi-contracts prevent one party from profiting unfairly to the detriment of another.
  • Restitution and Indemnification: The obligation primarily aims to restore the balance by requiring restitution or indemnification.

11. Key Articles in the Civil Code

  • Article 2142: General definition.
  • Articles 2144-2153: Negotiorum gestio.
  • Articles 2154-2160: Solutio indebiti.
  • Article 22: General principle against unjust enrichment.

12. Conclusion

Quasi-contracts serve as a mechanism for ensuring justice and equity in situations where no formal agreements exist but obligations arise due to lawful and voluntary acts. Understanding their nuances is critical for resolving disputes and maintaining fairness in the absence of explicit contracts.
