Which of the following is NOT a component of a legal contract?

In the context of contract law, a legal contract is formed based on several essential components. These components include an agreement, consideration, and legal purpose.

An agreement refers to the mutual understanding and acceptance of terms between the parties involved; it forms the basis of the contract itself. Consideration involves something of value that is exchanged between the parties, which can be in the form of money, services, or goods. Legal purpose means that the contract's terms must align with the law and cannot involve illegal activities or be against public policy.

Revocation, on the other hand, is a concept that pertains to the ability to annul or cancel a contract before the contract is executed or performed. While revocation is an important aspect of contract law – as it discusses the termination of the agreement or the ability to withdraw – it is not a fundamental component that must be present for an initial contract to be valid. Instead, it is an action that can occur concerning a contract. Therefore, this makes revocation the correct answer as it does not belong to the foundational elements of a legal contract.
