car accident, owner's or driver's liability OK personal injury law

Liability?: Bought a car for my grandson(22)who was not married to a women who had borne him two children. He said he would pay me for this car since he needed it to keep his job(commutting to Tulsa to work). He left her and move to Tulsa but left her the vehicle. She has never tranferred the title(still in original name of previous owner altho she signed as seller). But the big problem is she is driving without insurance. If she's in a at-fault accident who's to blame to cover cost to the other persons property? - Is this your question? Add additional information
