Just after my 18th birthday (1999) a relative co-signed on a vehicle with me.
They lived in TX and I lived in AZ. The vehicle was purchased in AZ.
A few days later I got into an accident. To make a long story short I now need to provide proof of insurance for the time period surrounding the accident.

My problem is that I barely knew the guy that cosigned. (He was my stepdad).
I had never had insurance before in my name so I assume the dealership where the vehicle was purchased took care of the insurance requirements.

My question is this... How do I go about getting proof of coverage for that vehicle for that time period? I don't know which insurance company covered the vehicle and my stepdad and mom are gone for good (MIA).

Per state law, there had to be coverage before the dealership would let the vehicle off their premesis.

Any help would be greatly appreciated.

Thanks,
Bob
