33.2 Defective Contracts

Key Takeaways

  • Philippine civil law establishes four distinct classes of defective contracts in ascending order of defectiveness: Rescissible, Voidable, Unenforceable, and Void/Inexistent.

  • Rescissible contracts under Article 1381 are valid and enforceable until judicially rescinded; they are grounded in economic damage or lesion (such as ward contracts with lesion exceeding 25% or alienations in fraud of creditors via accion pauliana), serve as a subsidiary remedy, and prescribe in four years.

  • Voidable contracts under Article 1390 are valid until annulled; they arise from legal incapacity of one party or vices of consent, and may be cured through ratification, which retroactively cleanses the contract from its inception.

  • Unenforceable contracts under Article 1403 are valid agreements that cannot be sued upon in court unless ratified; they encompass unauthorized agency, contracts violating the Statute of Frauds (six categories), and contracts where both parties lack capacity; partial performance removes an oral agreement from the Statute of Frauds.

  • Void contracts under Article 1409 are null ab initio, produce no legal effect, cannot be ratified, and the defense of nullity is imprescriptible; under the in pari delicto doctrine, neither guilty party can recover or enforce performance, subject to narrow statutory exceptions for public policy, labor standards, and usurious interest.

Defective Contracts

Under the Civil Code of the Philippines, defective contracts are classified into four distinct, non-overlapping categories based on the gravity of their flaw, the nature of the damage caused, and the legal remedy provided. Governed by Book IV, Title II, Chapters 5 through 9 (Articles 1380 to 1422), mastering the hierarchy and nuances of defective contracts is among the most heavily tested areas in the CPALE Regulatory Framework for Business Transactions.

1. Rescissible Contracts (Articles 1380 to 1389)

Legal Status and Concept

A rescissible contract is a contract that has all the essential requisites of a valid contract (consent, object, cause) and is completely valid and legally binding until rescinded by a competent court. The defect is not intrinsic to the formation of the agreement; rather, it causes economic lesion, financial damage, or prejudice to one of the contracting parties or to a third person.

Statutory Causes under Article 1381

Under Article 1381, the following contracts are rescissible:

  1. Contracts Entered into by Guardians with Lesion: Contracts entered into by guardians whenever the wards whom they represent suffer lesion by more than one-fourth (more than 25%) of the value of the things which are the object thereof.
    • Exception (Article 1386): Contracts approved by courts of justice are NOT rescissible, regardless of the lesion suffered.
  2. Contracts Agreed upon in Representation of Absentees with Lesion: Contracts undertaken on behalf of absentees if the latter suffer lesion by more than one-fourth (more than 25%) of the value of the things.
  3. Contracts in Fraud of Creditors (Accion Pauliana): Contracts undertaken in fraud of creditors when the latter cannot in any other manner collect the claims due them.
  4. Contracts Involving Things under Litigation: Contracts which refer to things under litigation, entered into by the defendant without the knowledge and approval of the litigants or of competent judicial authority.
  5. Other Contracts Specially Declared by Law: All other contracts specially declared by law to be subject to rescission (such as payments made in a state of insolvency under Article 1382 for obligations to whose fulfillment the debtor could not be compelled at the time they were effected).

Cardinal Principles Governing Rescission

  • Subsidiary Remedy (Article 1383): The action for rescission is strictly subsidiary; it cannot be instituted except when the party suffering damage has no other legal means to obtain reparation for the same.
  • Mutual Restitution (Article 1385): Rescission creates the obligation to return the things which were the object of the contract, together with their fruits, and the price with its interest. Consequently, rescission can only be carried out when the person demanding rescission is in a position to restore whatever he may be obliged to return.
  • Bar to Rescission (Article 1385 par. 2): Rescission cannot take place when the things which are the object of the contract are legally in the possession of third persons who did not act in bad faith. In such case, the remedy is an action for damages against the person who caused the loss.
  • Prescriptive Period (Article 1389): The action to claim rescission must be commenced within four (4) years. The prescriptive period begins:
    • For persons under guardianship: from the termination of the ward's incapacity;
    • For absentees: from the time the domicile or whereabouts of the absentee become known;
    • For contracts in fraud of creditors (accion pauliana): from the time of discovery of the fraud.

2. Voidable Contracts (Articles 1390 to 1402)

Legal Status and Concept

A voidable contract (also termed an annullable contract) is valid, binding, and effective between the parties until annulled by a proper action in court. Once annulled, it is rendered void from the beginning (retroactive effect).

Statutory Causes under Article 1390

Under Article 1390, the following contracts are voidable, even though there may have been no damage to the contracting parties:

  1. Those where one of the parties is incapable of giving consent to a contract (minors, insane or demented persons, deaf-mutes who do not know how to write);
  2. Those where the consent is vitiated by mistake, violence, intimidation, undue influence, or fraud.

Prescriptive Period for Annulment (Article 1391)

The action for annulment must be brought within four (4) years. The counting of the 4-year period begins:

  • In cases of intimidation, violence, or undue influence: from the time the defect of the consent ceases;
  • In cases of mistake or fraud: from the time of the discovery of the same;
  • In cases of contracts entered into by incapacitated persons: from the time guardianship ceases (e.g., when the minor attains 18 years of age).

Ratification (Confirmacion, Articles 1392 to 1396)

Ratification is the voluntary act by which the injured party or their legal representative cleanses the contract of its defects, thereby waiving the right to file an action for annulment.

  • Forms of Ratification (Article 1393): May be express (written or oral declaration) or tacit (implied by acts implying a necessary intention to waive the right, such as accepting benefits or executing obligations under the contract after the vice has ceased).
  • Unilateral Nature (Article 1395): Ratification does not require the conformity of the other contracting party who caused the defect.
  • Retroactive Cleansing Effect (Article 1396): Ratification cleanses the contract from all its defects from the moment it was constituted, validating it retroactively ab initio.

Mutual Restitution upon Annulment (Articles 1398 and 1399)

  • General Rule (Article 1398): Contracting parties must restore to each other the subject matter of the contract with its fruits, and the price paid with legal interest.
  • Exception for Incapacitated Persons (Article 1399): When the defect of the contract consists in the incapacity of one of the parties, the incapacitated person is not obliged to make any restitution except insofar as he has been benefited by the thing or price received by him.

3. Unenforceable Contracts (Articles 1403 to 1408)

Legal Status and Concept

An unenforceable contract is a valid agreement, but it cannot be enforced by action or sued upon in a court of justice unless it is ratified in accordance with law. Third persons cannot assail an unenforceable contract (Article 1408).

The Three Distinct Classes under Article 1403

Under Article 1403, three classes of contracts are unenforceable:

The Statute of Frauds (Article 1403 No. 2)

The Statute of Frauds requires that certain agreements must be evidenced by some note or memorandum in writing, subscribed by the party charged or by their agent; otherwise, the agreement cannot be proved in court without the consent of the other party.

The Six Contracts Covered by the Statute of Frauds

  1. Agreement not to be performed within a year: An agreement that by its terms is not to be performed within one (1) year from the making thereof;
  2. Special promise to answer for the debt, default, or miscarriage of another: Collateral promises of guaranty or suretyship (an original promise where the promisor assumes primary liability is outside the statute and enforceable orally);
  3. Agreement in consideration of marriage: Agreements made in consideration of marriage, other than a mutual promise to marry (e.g., pre-nuptial property settlements or marriage settlements);
  4. Sale of goods, chattels, or things in action at PHP 500 or more: Agreement for the sale of goods, chattels, or things in action, at a price not less than PHP 500, unless the buyer accepts and receives part of such goods and chattels, or pays at the time some part of the purchase money;
  5. Lease for more than one year, or sale of real property: An agreement for the leasing for a longer period than one (1) year, or for the sale of real property or of an interest therein;
  6. Representation as to the credit of a third person: A representation as to the credit of a third person.

The Doctrine of Part Performance

CPALE Rule: The Statute of Frauds applies EXCLUSIVELY to wholly executory contracts (contracts where neither party has performed). If there has been partial or total execution (such as partial delivery, partial payment, or possession accompanied by improvements), the contract is taken completely out of the Statute of Frauds, and oral evidence is fully admissible to prove the contract!

Waiver of the Statute of Frauds (Article 1405)

Contracts infringing the Statute of Frauds are ratified and become enforceable:

  1. By the failure to object to the presentation of oral evidence to prove the contract during trial; or
  2. By the acceptance of benefits under the contract.

4. Void and Inexistent Contracts (Articles 1409 to 1422)

Legal Status and Concept

A void contract is an absolute nullity (null and void ab initio). It has no legal existence, produces no legal effect whatsoever, and creates no rights or obligations. It cannot be confirmed, validated, or cured by ratification.

Statutory Causes under Article 1409

Under Article 1409, the following contracts are inexistent and void from the beginning:

  1. Those whose cause, object, or purpose is contrary to law, morals, good customs, public order, or public policy;
  2. Those which are absolutely simulated or fictitious;
  3. Those whose cause or object did not exist at the time of the transaction;
  4. Those whose object is outside the commerce of men;
  5. Those which contemplate an impossible service;
  6. Those where the intention of the parties relative to the principal object cannot be ascertained;
  7. Those expressly prohibited or declared void by law (e.g., sale between spouses under Article 1490; purchase of property under administration by guardians, agents, or executors under Article 1491).

Key Principles Governing Void Contracts

  • Imprescriptibility (Article 1410): The action or defense for the declaration of the inexistence of a contract does not prescribe. A party may raise the defense of absolute nullity at any time.
  • Cannot be Ratified (Article 1409 par. 2): A void contract cannot be validated by ratification or by the passage of time.
  • Standing of Third Persons (Article 1421): The defense of illegality of contracts is available to third persons whose interests are directly affected.

The Doctrine of In Pari Delicto (Articles 1411 and 1412)

The principle of in pari delicto (in pari delicto potior est conditio defendentis) dictates that when both contracting parties are in equal fault in an illegal contract, the law leaves them where it finds them. Neither party may maintain an action against the other to enforce the contract or recover what was delivered.

Classification of Illegal ActBoth Parties at Fault (In Pari Delicto)Only One Party at Fault
Act Constitutes a Criminal Offense (Article 1411)Neither party can recover; both are subject to criminal prosecution; instruments of the crime are forfeited to the StateInnocent party may recover what he has given, and is not bound to comply with his promise
Act Does Not Constitute a Crime (Article 1412)Neither party can recover what he has given or demand performance of the other's undertakingGuilty party cannot recover or demand performance; innocent party may recover what he gave without obligation to comply

Statutory Exceptions to In Pari Delicto (Where Recovery is Permitted)

To prevent injustice and advance public policy, the Civil Code explicitly permits recovery despite the illegal agreement in the following cases:

  1. Article 1414 (Repudiation before Illegal Purpose Achieved): When money is paid or property delivered for an illegal purpose, the person who paid or delivered may recover it from the other if he repudiates the agreement before the purpose has been accomplished, or before any damage has been caused to a third person, if public interest will be subserved.
  2. Article 1415 (Incapacitated Party): Where one of the parties to an illegal contract is incapable of giving consent, the courts may, if the interest of justice so demands, allow recovery of money or property.
  3. Article 1416 (Prohibition for Protection of Plaintiff): When the agreement is not illegal per se but is merely prohibited, and the prohibition by law is designed for the protection of the plaintiff, he may recover what he has paid or delivered.
  4. Article 1417 (Excess of Price Ceilings): When the price of any article or commodity is determined by statute or law (price control laws), any person paying any amount in excess of the maximum price may recover such excess.
  5. Articles 1418 and 1419 (Labor Standards): An employee who works beyond the statutory maximum hours or accepts compensation below the statutory minimum wage may recover overtime pay or the wage deficiency, despite any contrary agreement.
  6. Usurious Interest (Article 1413): Any person who pays interest in excess of that allowed by usury laws may recover the whole interest paid with legal interest thereon.

6. Comprehensive Worked Problem Scenarios

Problem 1: Guardian Contract with Lesion and Court Approval Trap

Scenario: Mario is the legal guardian of Mateo, a 16-year-old orphan. Mateo inherited a prime commercial parcel of land in Davao City with a prevailing fair market value of PHP 12,000,000. Mario, acting as guardian on behalf of Mateo, entered into a contract of sale selling the land to Oscar for PHP 8,500,000. Mario obtained express judicial approval from the Regional Trial Court having jurisdiction over the guardianship proceedings before executing the deed of sale. Upon reaching the age of 18, Mateo discovers that the land was sold for PHP 8,500,000 when it was worth PHP 12,000,000 (a lesion of PHP 3,500,000, which is approximately 29.17% of the value). Within two years of reaching majority, Mateo files an action to rescind the contract of sale under Article 1381(1). Will the action for rescission prosper?

Analysis:

  1. Computation of Lesion:
Lesion Amount=PHP 12,000,000−PHP 8,500,000=PHP 3,500,000Percentage of Lesion=PHP 3,500,000PHP 12,000,000=29.17%\begin{aligned} \text{Lesion Amount} &= \text{PHP }12{,}000{,}000 - \text{PHP }8{,}500{,}000 = \text{PHP }3{,}500{,}000 \\ \text{Percentage of Lesion} &= \frac{\text{PHP }3{,}500{,}000}{\text{PHP }12{,}000{,}000} = 29.17\% \end{aligned}

Because 29.17%>25%29.17\% > 25\% (more than one-fourth), the lesion threshold under Article 1381(1) is met. 2. The Judicial Approval Exception (Article 1386): Under Article 1386 of the Civil Code: "Rescission referred to in Nos. 1 and 2 of Article 1381 shall not take place with respect to contracts approved by the courts." 3. Conclusion: Because the sale was approved by a competent court of justice prior to execution, the contract cannot be rescinded under Article 1381(1). Mateo's action for rescission will NOT prosper.

Problem 2: Statute of Frauds and Doctrine of Part Performance

Scenario: Fernando orally agreed to sell a residential house and lot in Iloilo City to Graciela for PHP 3,000,000. Graciela paid Fernando an initial down payment of PHP 300,000 in cash, and Fernando handed over the keys to the property. Graciela immediately took physical possession of the house and expended PHP 200,000 on roof repairs and painting. Two months later, Fernando received a higher offer of PHP 4,500,000 from another buyer. Fernando tendered the return of the PHP 300,000 down payment to Graciela and refused to execute a deed of absolute sale, contending that under Article 1403 No. 2(e) (Statute of Frauds), an oral agreement for the sale of real property is unenforceable. Can Graciela compel Fernando to execute the formal deed of sale?

Analysis:

  1. Statute of Frauds Scope: Article 1403 No. 2(e) requires contracts for the sale of real property to be in writing to be enforceable.
  2. Application of the Doctrine of Part Performance: The Statute of Frauds applies exclusively to wholly executory contracts. Where an oral contract has been partially performed, equity intervenes to prevent the statute from being used as a shield for fraud.
  3. Acts of Partial Performance: Graciela made partial payment of PHP 300,000, took physical possession of the property with the seller's consent, and made valuable capital improvements (PHP 200,000 repairs). These acts take the oral contract completely out of the Statute of Frauds.
  4. Right to Compel Execution (Article 1357): Because the oral contract is valid and taken out of the Statute of Frauds, Graciela has the legal right under Article 1357 to compel Fernando to execute a public instrument of sale.
  5. Conclusion: Graciela can legally compel Fernando to execute the deed of absolute sale. Fernando's defense under the Statute of Frauds must fail.
Test Your Knowledge

A contract was entered into between Juan, a 16-year-old high school student, and Pedro, a 17-year-old freshman college student, whereby Juan sold his high-end gaming laptop to Pedro for PHP 45,000. Juan's parents discovered the transaction two weeks later and expressly ratified the contract in writing. Pedro's parents, however, upon learning of the purchase, vehemently opposed it and filed an action in court to invalidate the sale. What is the legal status of the contract?

A

The contract is voidable because the ratification by Juan's parents converted the contract into a voidable contract subject to annulment by Pedro's representatives.

B

The contract is completely void ab initio because both contracting parties were unemancipated minors incapable of giving consent.

C

The contract is fully valid and enforceable because the ratification by one party's parents cleanses the contract retroactively from perfection.

D

The contract remains unenforceable because ratification requires the concurrent written consent of the parents of both contracting parties.
