Putting someone in charge of any type of situation can be intimidating. You certainly want to choose the right person for the job and ensure that he or she also feels comfortable taking on the role. When it comes to appointing a power of attorney agent, you may feel a bit apprehensive about giving that much responsibility to just anyone.
First of all, you certainly should not appoint "just anyone" as your agent. There is a possibility that abuse of power could occur when it comes to handling your finances. Because this person will take on the role of agent in the event of your incapacitation, you may worry about not having the ability to combat potential abuse.
