Understanding the Nature of Obligations
Definition and Characteristics of Obligations
Obligations form the backbone of civil law, representing the legal duty of a person (the
debtor) to give, to do, or not to do something for the benefit of another (the creditor).
According to Hector de Leon, obligations are essentially juridical bonds that link two or
more parties, where one or more are bound to act or refrain from acting in a certain
manner. The main characteristics include:
Legal Bond: Obligations are founded on law, contracts, or other juridical acts.
Mutuality: They involve at least two parties with reciprocal duties.
Enforceability: They are enforceable by law, allowing the creditor to seek judicial
remedy if breached.
Unilateral or Bilateral: Obligations can be unilateral (one party's duty) or bilateral
(mutual duties).
Sources of Obligations
Hector de Leon categorizes the sources of obligations into several key areas:
Law: Obligations arising from legal provisions or statutes.1.
Contracts: Agreements voluntarily entered into by parties that create obligations.2.
Delicts or Torts: Obligations resulting from unlawful acts causing damage to3.
others.
Quasi-contracts: Obligations arising not from agreement but from certain acts that4.
give rise to legal duties, such as negotiorum gestio or solutio indebiti.

Elements of a Valid Contract
Essential Elements
Hector de Leon emphasizes that for a contract to be valid and enforceable, it must
possess certain essential elements:
Consent: The genuine agreement of the parties, free from vices such as violence,
intimidation, fraud, or mistake.
Object: The subject matter of the contract must be lawful, certain, and possible.
Cause: The reason or purpose which justifies the obligation, also lawful and not
immoral.
Formal and Formalities
While most contracts are valid even in informal forms, certain types require specific
formalities under law, such as:
Writing
Notarization
Registration
Hector de Leon discusses how the absence of required formalities can invalidate specific
contracts, such as real estate agreements.
Classification of Contracts
Based on Formation
Contracts can be classified into:
Consensual: Valid upon the mere consent of the parties (e.g., sale, lease).
Real: Require delivery of the object to be perfected (e.g., loan, deposit).
Formal: Require compliance with legal formalities (e.g., authentic act for sale of
real property).
Based on Nature and Effect
Hector de Leon also discusses contracts based on their effect:
Unilateral: Only one party assumes an obligation.
Bilateral: Both parties assume mutual obligations.
Commutative: The value of the prestation is equivalent to the other.
Aleatory: The performance depends on an uncertain event (e.g., insurance).
