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.
A typical POA continues until you revoke it, become incapacitated, or die. A durable power of attorney remains effective even if you become incapacitated. You can limit the POA to a specific time period, to accomplish a particular goal, or to perform a specific task such as writing checks. You can revoke power of attorney at any time, unless you're found to be without the mental capacity to do so.
