You are not personally obligated to pay a debt owed by your late father, even if you are executor. His estate such as it is bears the burden of the debt, and if it cannot be paid out of the estate then the debtor is out of luck. Do not assume a debt you do not owe and cannot afford.
I have been to a lawyer.
What Bank of America did was six weeks after his death, they transferred my father’s credit card balance, WHICH HE HAD AN INSURANCE POLICY ON THROUGH THE BANK, to a new account and stuck my name on it thereby making it my debt.
The lawyer said because I was an approved user of said credit account (POA) due to my father being incompetent, BofA did what they did. It is legal in the State of Washington.
Being an authorized user does not give them the right to create a new account without your authorization and obligate you to pay... your attorney is a jackass.. Contact legal aid or just make them sue you and when you get to court all you have to claim is
1.) I did not create or authorize this account , the debt is not mine
2.) Show me the contract with my wet ink signature
Then sue the cr*p out of them for their illegal actions, identity theft.
