What does the legality of subject matter in a contract imply?

The legality of subject matter in a contract refers to the requirement that the content and purpose of the contract must be lawful. In other words, a valid contract cannot include any terms or activities that are illegal or against public policy. If a contract involves illegal activities, such as drug trafficking or fraud, it is considered void and unenforceable in a court of law. This principle ensures that contracts promote lawful behavior and the legal system's integrity. Therefore, for a contract to be valid, it is essential that the subject matter does not violate any laws or regulations.
