glad to hear she is OK.
With injury claims the insurance company will normally assign an injury lawyer for you, which they seem to have done . The insurance companies have now set basic payouts for certain injuries.
When I was rear ended a couple of years ago after a few forms and a brief once over by a doctor from the insurance firm I was paid £1500 for the whiplash, I actually had pains in the tops of my legs which was a result of the whiplash, she should look out for that and pains in the arms, numbness in the fingers too could be caused by nerve inflamation caused by the whiplash. took about 3 months in total to receive the settlement. I was told if I wanted more I would have to pay the fees myself.
She should go to the doctors for any ill affects she may be suffering from that could be linked to the crash, as the payouts are based on time to recover and and what she is not able to do. ie lofting any kids, normal daily routine that is affected.
Just a bit concerned that the other driver admitted liability at the scene. I was always told not to do this as the insurance companies get upset.
