Legal document by which a person with assets (the principal) appoints another person (the agent) to act on the principal's behalf, even if the principal becomes incompetent. If the power of attorney is not "durable," the agent's authority to act ends if the principal becomes incompetent. The agent's power to act for the principal may be broadly stated, allowing the agent to buy and sell securities, or narrowly stated to limit activity to selling a car.
