👉 An invalidator is a person or entity that performs an action that has not been authorized, approved, or granted by someone else. In legal terms, it's often used to refer to an unauthorized act or transaction that violates regulations, laws, or contracts. The term "invalidator" can also be used in the context of fraud or deception, where the person performing the invalidation is accused of deceiving others into believing they had no authority or permission to perform a specific action.
