What does the agent's duty of confidentiality involve?

The duty of confidentiality for an agent primarily involves keeping all information related to the principal private. This principle is crucial in the agent-principal relationship, as it ensures that sensitive information shared by the principal is protected from unauthorized disclosure. This obligation fosters trust and encourages open communication between the principal and the agent.

In this context, the agent must not disclose any information that may disadvantage the principal or benefit others at the principal's expense. This duty persists even after the agency relationship ends, meaning that the agent must continue to honor the confidentiality of the principal's private information indefinitely, barring exceptional circumstances where disclosure might be legally required.

The other choices do not accurately capture the essence of the confidentiality duty. Sharing information only with other agents may breach the obligation if it leads to unauthorized disclosure. Documenting communications, while important for record-keeping, isn't directly related to the duty of confidentiality. Lastly, publicly disclosing information contradicts the very principle of confidentiality and undermines the trust necessary for a healthy agent-principal relationship.
