Revocation is the formal cancellation or withdrawal of a legal right, privilege, or agreement. This process can occur in various contexts, such as the revocation of a driver's license, where authorities remove an individual's permission to drive due to violations. It can also apply to contracts, where one party may withdraw their consent, rendering the agreement void. In the context of law, revocation can be initiated by a governing body or an individual, depending on the situation. For example, a will can be revoked by the testator if they decide to create a new will or change their mind about their previous wishes.
