A durable power of attorney refers to the agentâs authority when the principal is incapacitated. A non-durable power of attorney, or a general power of attorney, does not allow the agent to act in the interests of the principal if the latter becomes incapacitated.

An agent acts as the principalâs legal representative in matters that the principal is unable to attend to personally.
