Under the Civil Code of Cambodia, certain legal grounds can render a contract null and void. Contracts may be declared null (void ab initio, meaning they are considered never to have existed) or voidable (valid until annulled by one of the parties). The grounds for nullity are based on the principle that a contract must be formed with legal capacity, lawful purpose, mutual consent, and in accordance with public order and good morals. Below are the key legal grounds for declaring a contract null and void under Cambodian law:

1. Lack of Legal Capacity (Articles 333 – 336)

•    A contract may be declared null and void if one of the parties lacked legal capacity at the time the contract was formed. This includes contracts entered into by:
•    Minors: Persons under the age of 18, unless they are emancipated or have legal capacity for certain transactions.
•    Incompetent Persons: Individuals who have been declared incompetent by a court due to mental illness or other reasons that impair their ability to understand the nature and consequences of the contract.

2. Absence of Genuine Consent (Articles 337 – 340)

• A contract requires the genuine consent of all parties. If consent was not freely given, the contract may be voidable. Grounds for lack of genuine consent include:
• Mistake: If one party was mistaken about a fundamental aspect of the contract, such as the nature of the agreement or the identity of the other party, the contract may be voidable.
• Fraud: If one party was induced to enter into the contract through fraudulent misrepresentation or deceit, the contract can be declared void.
• Duress: If one party was forced or coerced into entering the contract under threat or undue pressure, the contract may be voidable.

3. Illegality of the Object or Purpose (Articles 351 – 353)

•    A contract is null and void if its object (the subject matter of the contract) or purpose is illegal or against public order and good morals. Examples include:
•    Contracts for Illegal Activities: Any contract that involves activities prohibited by law, such as contracts for illegal trade, smuggling, or other criminal acts.
•    Contracts Contrary to Public Policy: Contracts that violate public order, public policy, or good morals, even if the activities are not explicitly illegal.

4. Lack of Form (Article 331)

• Certain contracts are required to be in writing or to follow specific formalities under Cambodian law. If a contract does not comply with the required form (e.g., written form for a sale of immovable property), it may be declared null and void.

5. Simulated Contracts (Article 339)

•    Contract may be declared void if it is a “simulated” contract, meaning the parties did not intend the contract to have legal effect. This often occurs when parties create a contract solely to deceive others or to circumvent legal obligations.

6. Contracts Made by Unauthorized Persons (Article 334)

•    If a contract is made by a person without proper authority to represent one of the parties (such as an agent acting outside the scope of their authority), the contract may be void unless ratified by the represented party.

7. Contracts for Future Inheritance (Article 354)

•    Contracts concerning the inheritance of a living person (agreements about the distribution of an estate before the death of the person) are generally null and void under Cambodian law, as they are considered contrary to public order and good morals.

8. Inadequate Consideration or Gratuitous Promises (Article 342)

•    A contract may be declared void if it is found to be a gratuitous promise (a promise made without any return consideration), unless it meets the requirements for formal validity (such as being in writing) as stipulated by law.

9. Invalidity Due to Non-Performance of Conditions (Article 343)

•    If a contract is conditional and the condition is not fulfilled, the contract may be declared null and void. This applies to both suspensive conditions (conditions that must be met for the contract to take effect) and resolutory conditions (conditions that, if met, will terminate the contract).

Legal Consequences of Nullity

•    Restitution (Article 351): If a contract is declared null and void, both parties are generally required to return any benefits they received under the contract. This is to restore the parties to their original positions as if the contract had never existed.
•    Third-Party Rights (Article 353): In some cases, the nullity of a contract may affect the rights of third parties who acted in good faith. The law provides protection for such third parties, particularly in property transactions.

Conclusion

Contracts under Cambodian law must meet specific legal requirements to be valid and enforceable. When a contract is found to lack legal capacity, genuine consent, legality, or proper form, it may be declared null and void. Understanding these grounds is essential for both parties when entering into contracts, as well as for resolving disputes that may arise from potentially invalid agreements. Legal counsel is recommended to navigate complex situations where contract validity is in question.
