Can you be charged storage fees for a vehicle that was impounded liened and purchased by storage company?
I owned a vehice that was impounded and sold. This happened 3 years ago and I don't remember if I file release of liability form with Dept. of Motor Vehicles. I paid for one storage fee because it was stored at that facility when it was sold. One year later I get another notice that I owed more storage fees from another storage facility and I know that the car was sold to someone else. What should I do besides send a letter to DMV requesting copies of the Realese of Liability form.
