The main distinction between the two documents is that as soon as you die, the representative you designate via power of attorney loses their legal authority to deal with any matters in your place.
There are two primary ones among the power of attorney varieties:
General power of attorney - allows you to name a proxy (agent) who'll be able to take care of your monetary and legal matters in your stead. However, this document becomes annulled if the principal passes away or becomes incapacitated.
Durable power of attorney - grants the identical authority to the proxy as the prior type but continues to be effective even when the individual on behalf of whom the agent acts becomes disabled.
An executor is a person you establish in the will to deal with your affairs once you depart this life. It is possible to appoint one individual to act as an attorney-in-fact and a will executor.
