To revoke a formal agreement is to do what?

To revoke a formal agreement means to officially cancel or annul it. The term that perfectly describes this action is "rescind," which indicates that the agreement is rendered void and no longer holds any legal effect. When a formal agreement is rescinded, all parties involved are released from their obligations under that agreement. This term is commonly used in legal contexts to refer to the act of withdrawing from a contract or an agreement, highlighting that the original intent and terms are no longer valid.

In contrast, the other terms do not accurately capture the essence of revocation. To establish an agreement means to create it, which is the opposite of revoking. Modifying an agreement would involve making changes to its terms rather than canceling it entirely. Neglecting an agreement implies that it is not acted upon or followed, but it does not convey the formal cancellation aspect inherent in revocation. Thus, "rescind" is the most appropriate choice for describing the act of revoking a formal agreement.
