My son and I went for a ride at the weekend. My son riding his motorcycle slipped on the road and consequently knocked me off my motorcycle. He has comprehensive motorcycle insurance and I am uninsured. His insurance company is claiming that because we live under the same roof they will not pay for the repairs to my bike. We individually own each bike there are two individual registrations there is no cross ownership on either bike. In a police report, my son was held responsible for the motorbike accident. Do I have a case against my son's insurer? I am not about to sue my son as I do not hold him responsible for what I see to be an unfortunate accident.
