My son was asked to drive a friends car with permission from the friend not the parent. He crashed and caused $3000. in damages. My insurance company told me it was the car owners responisbility to file the claim and we offered to pay the deductible. The insured does not want to file a claim because her insurance will be dropped. Her deductible is $750. Are we now responisble to pay $1500 (half of the $3000) or $750? Or could she take us to court for the whole thing?
