What action must a principal take to revoke an agency relationship?

To revoke an agency relationship, the principal must take the appropriate action to communicate their decision effectively to the agent. Notifying the agent in writing is a clear and formal way to express the intent to terminate the agency. This ensures that there is a documented record of the revocation, which can be important for legal clarity and to prevent misunderstandings.

The other options do not accurately capture the essential action needed for revocation. While obtaining a new agent may be a necessary step for the principal moving forward, it is not a requirement for revocation of the existing relationship. Changing the terms of the agreement might lead to modifications but does not automatically terminate the agency. Holding a formal meeting could potentially serve as a method of communication, but it is not necessary if the revocation is conveyed in writing. The written notice provides a direct and unequivocal means to end the agency relationship.
