My grandson (17 years old) was a passenger in a car with one of his friends. They were hit by a car, which was determined to be the other cars fault. A few days later both the driver and my grandson developed back problems. The driver has subsequently sought medical treatment and has contacted an attorney. This happened in May 1012 in Michigan. My daughter has not taken him to the doctor nor does she want to seek legal help because she claims that: (1) Her insurance will be affected. (2) Because he has waited this long there is no point in contacting an attorney. She claims even though her son was in another car, Michigan no fault will not allow her to sue the insurance company of the other car or the insurance company of the driver of the car my grandson was in. Does she have to notify her insurance company to begin any claim?
