My question involves Title/Registration in the State of North Carolina.

I have a car titled in my name, deceased mother's name, and the bank financing the car loan. I want to sell this vehicle because I have no use for it. Can i sell it to a dealership (carmax) even though a deceased person is on the title ? I read I may need power of attorney to do this. What else is involved ? Necessary forms, actions from DMV etc. ?
