The person you name to help you in your POA is called an “agent”.
1. Did you name a backup agent?
Many people name one person, and fail to name a backup. What if something happens to the person you have named in your POA?
2. If you named more than one person, then in what order will they act?
You can name one person first, another person second, and still another person as third.
Or you can name two persons on the same level. But does these two persons need to act together jointly, or have you included language that they can act separately and independently with no requirement that they act together jointly.
