A power of attorney refers to a written instrument, executed by one person (the principal) that allows another person (the attorney in fact) to act on their behalf. If the principal dies the power of attorney is extinguished. If the attorney in fact dies the principal must execute a new power of attorney that names a new attorney in fact.
If a power of attorney is durable, it remains valid and in effect even if you become incapacitated and unable to make decisions for yourself. If a power of attorney document does not explicitly say that the power is durable, it ends if you become incapacitated. But wait. There is more. There are two kinds of durable powers of attorney: a durable power of attorney for finances lets you name someone to manage your financial affairs if you become incapacitated, and a durable power of attorney for health care allows someone to make medical decisions for you if you are no longer able to speak for yourself.
