What does "legality" mean in contract law?

In contract law, "legality" refers to the principle that a contract's purpose must be lawful. This means that for a contract to be enforceable, it cannot involve activities or objectives that violate laws or public policy. If the purpose of a contract is illegal, such as agreements to commit crimes or engage in fraudulent activities, the contract is considered void and cannot be enforced in a court of law.

The concept of legality is fundamental, as it ensures that the contractual framework operates within the boundaries set by society's laws and ethical standards. This principle protects individuals and the public from the consequences of unlawful agreements, ensuring that legal remedies are only available for contracts that align with legal norms.
