Fiduciary Duty (OLD CAR)
Definition
The highest legal standard of care owed by an agent to their client. In Massachusetts, exclusive buyer representation guarantees full fiduciary duties: Obedience (follow lawful instructions), Loyalty (prioritize buyer's interests), Disclosure (reveal material facts), Confidentiality (protect sensitive info), Accounting (handle funds properly), Reasonable Care (professional skill). Acronym: OLD CAR.
Example
Your exclusive buyer's agent has a fiduciary duty to keep your $750K maximum budget confidential and negotiate aggressively to get the best price—never revealing your ceiling to the seller. If they become a Dual Agent, they lose Loyalty, Obedience, and full Confidentiality.
