In the architecture of the Philippine Civil Code, a contract is defined by the meeting of minds between two persons whereby one binds himself, with respect to the other, to give something or to render some service. However, for a contract to be fully enforceable and beyond reproach, the "meeting of minds" must be free, conscious, and spontaneous.
When consent is obtained through illicit means, the contract is not void ab initio (from the beginning), but is classified as voidable. These contracts are binding unless they are annulled by a proper action in court.
I. The Nature of Voidable Contracts
Under Article 1390 of the Civil Code, voidable contracts are those which possess all the essential requisites of a contract (consent, object, and cause) but suffer from a defect that vitiates the consent of one of the parties.
Key Characteristics:
- Valid until annulled: They produce legal effects until a court decrees their annulment.
- Ratifiable: The defect can be cured through "ratification," which cleanses the contract of its defects from the moment it was constituted.
- Prescription: The action for annulment must be brought within four years.
II. Grounds for Annulment
The law provides two primary categories of voidable contracts:
- Those where one of the parties is incapable of giving consent (Legal Incapacity).
- Those where the consent is vitiated by vices of consent.
1. Legal Incapacity
Consent is invalid if given by individuals who the law deems unable to fully understand the consequences of their actions. This includes:
- Unemancipated minors.
- Insane or demented persons (unless the contract was entered into during a lucid interval).
- Deaf-mutes who do not know how to write.
2. Vices of Consent (MISTIV)
The integrity of consent is the bedrock of contract law. Under Article 1330, consent is vitiated—and the contract becomes voidable—when it is given through:
- Mistake
- Intimidation
- Violence
- Undue Influence
- Fraud
III. Deep Dive: The Vices of Consent
A. Mistake (Error)
Not every mistake justifies an annulment. To vitiate consent, the mistake must be substantial. It must refer to:
- The substance of the thing which is the object of the contract.
- The conditions which principally moved one or both parties to enter into the contract.
- The identity or qualifications of one of the parties, but only if such identity was the principal cause of the contract.
Note: Simple errors of account (mathematical errors) do not lead to annulment; they only give rise to correction.
B. Violence
Violence exists when, in order to wrest consent, irresistible physical force is employed. The force must be of such a degree that the victim has no choice but to submit.
C. Intimidation (Moral Coercion)
Intimidation occurs when one of the parties is compelled by a reasonable and well-grounded fear of an imminent and grave evil upon his person or property, or upon the person or property of his spouse, descendants, or ancestors.
- Factors to consider: Age, sex, and condition of the person must be taken into account to determine the degree of intimidation.
- What it is not: A threat to enforce one's claim through competent authority (e.g., "I will sue you if you don't pay") does not vitiate consent if the claim is just or legal.
D. Undue Influence
This occurs when a person takes improper advantage of his power over the will of another, depriving the latter of a reasonable freedom of choice. This often arises in relationships of trust (e.g., teacher-student, doctor-patient) or when the victim is suffering from mental weakness, ignorance, or financial distress.
E. Fraud (Causal Fraud / Dolo Causante)
Under Article 1338, fraud occurs when, through insidious words or machinations of one of the contracting parties, the other is induced to enter into a contract which, without them, he would not have agreed to.
- Causal Fraud vs. Incidental Fraud: Only Dolo Causante (causal fraud) makes a contract voidable. Dolo Incidente (incidental fraud) only obliges the person employing it to pay damages.
- Dealer's Talk: Usual exaggerations in trade (e.g., "the best coffee in town") are not fraudulent when the other party had an opportunity to know the facts.
IV. Prescription Periods
The four-year period to file for annulment begins at different times depending on the ground:
| Ground | Start of Prescription Period |
|---|---|
| Intimidation, Violence, Undue Influence | From the time the defect/force ceases. |
| Mistake or Fraud | From the time of the discovery of the same. |
| Incapacity | From the time the guardianship ceases (e.g., reaching the age of majority). |
V. Effects of Annulment
Once a contract is annulled, the parties are generally required to restore to each other the things which have been the subject matter of the contract, with their fruits, and the price with its interest. The goal is to return the parties to their status quo ante—the condition they were in before the contract was executed.
If the ground for annulment is the incapacity of one party, the incapacitated person is only obliged to restore the thing or price to the extent that he was benefited by it.
