I was in a severe car accident a couple of years ago; I was in a medically induced coma and then was unable to take care of myself for a while afterwards due to a traumatic brain injury. Because of this, my mother was able to get power of attorney. I suspect that my mother received settlement money from both Menard’s (the company whose truck I was in an accident with) and her insurance company. How would I go about finding out if anything like this took place without my knowledge?
I was told she got power of attorney over me, in order to make medical decisions, but I believe the next of kin has that right without a power of attorney, if you are unable to make decisions for yourself.
