Obtaining credit cards
my mother has been diagnosed several months ago with dimentia. I have power of attorney. My nephew has acquired several credit cards in my Mom’s name and is having them sent to another address and he is listed as secondary card holder. My mother is on a fixed income and I just found out about these debts that she did not make or authorize. He also took her to an attorney to get papers signed, of which my mother does not know what or who the attorney was due to her mental condition. I need to know if I should file have bankruptcy on these debts or if this is a case for the Commonwealth for this. No one in my family is aware of my POA. Which direction should I take. Thank you.

Power of attorney for care of children
My wife and I are having issues at home I want to grant my siste POA for a period of time so that our children (my wife’s and mine) do not have to go through this instability. Is the correct the POA form named above the right one and how strong of a document is it? Meaning can a school , hospital, etc contest it?
