Actually ALL of us should have advanced directives, durable power of attorney, living trusts and wills made out because life is fragile with or without cancer. My wife and I had ours done after my diagnosis at a paralegal and it only costs about 500 bucks -far less then what the state would take in a probate court. Power of attorney for bank accounts can be dealt with directly at the bank. Once it's done it's done and it can be easily updated and amended.
