I'm hoping to get some advice for my mum on a neighbour issue, I'm sorry if it's long!
My mum's property is on a converted farm which has a communal car park. The farm was converted approx 55 years ago. Next to the car park is a field with a boundary wall. The car park is higher than the field so only the top of the wall is really visible from mums side.
About 18 months ago, during a storm, some of the top stones from the wall fell and collapsed into the field. They checked the deeds and the wall belongs to the neighbouring field so it was left assuming the owner wasn't bothered to fix it.
A couple of days ago the field owner turned up at Mums door and informed her that the liability for the wall sits with the owners of the car park because 'the wall should have been reinforced 55 years ago when the conversion was done'. He was talking thousands of pounds so she is very stressed. Personally I think he's trying it on. The wall has stood for 55 years with no issues, it was storm damage that caused it to collapse. It's HIS wall, which he freely admits, I don't believe that it's mum's problem. His basis for his argument seems to be that he remembers his dad saying that the wall should be reinforced when the building works were originally being done. Well he probably should have done something about it at the time then! Is there any liability here?
