My father accidentally reversed into a six foot garden wall in his car. The wall promptly collapsed onto his car, so his car is a write-off and the wall will probably all need to be replaced as it is extensively damaged. Will my father's insurance cover the damage to the wall as it has been suggested that they will only cover the damage to his car and the people who own the wall will have to claim on their house insurance. They are understandably not very happy about this as they didn't ask to have their wall destroyed.
