A woman is trying to bill us for damage to her car after she was coming out of a cul de sac and collided with my 6 year old son on his friends bike. She was coming straight on (was luckily slowing down) and my son collided into the side of her car.
She claims she didn't see him despite seeing him and his friend playing as she went into the cul de sac and thinks we should pay for the damage to the side of her car to stop her insurance increasing. While I was sympathetic because she uses her car for work (and was driving away from a job) my son was Injured from the handle bars hitting his chest and I took him to A&E to get checked over. He's got minor bruising. The woman has been rather cheeky and messaged half an invoice of "damage estimates" which have been hand written and have no header from a garage. My son dented the wing panel and the handle bars have scratched the passenger door. These estimates are from a family friends garage.
She's not reported the incident to the police but is demanding we pay. She hurt my son and I'm cross she's trying to get about 400 quid from us.
Legally do we have to pay?
