It was wet out and as he was coming off of a roundabout and still leaning left the car in front did a emergency stop,my partner lost control of the bike as it slid out from under him,the bike slid into the back of the car,followed by my partner,hitting his head on the back tyre,the driver admitted it was his fault.My partner had leg injuries and roadrash,was unable to work for six days,he has a lot of damage to his bike and had to replace crash hemet and safety gear,the problem is ,the driver is now claiming on my partners insurance,and denies he admitted fault.we now have a massive bill to pay for repairs to the bike.Does anyone know legally where we stand in this situation,as my partner didnt physically drive into the back of the car
