Hi, my parents are in their 70s and having a dispute over a retaining wall/wall.
Twenty years ago, my parents purchased a plot of land off their neighbour to build a new house.
The neighbour lowered their land level and build a standard wall on the boundary (my parents' land is about 1 metre higher).
My parents built a fence on their side, as per the conditions on their deeds. The fence and its foundations caused the neighbour's wall to collapse.
The neighbour claimed on my parent's insurance and was awarded a sum of nearly £20k (which the insurer disclosed to my dad recently following lots of attempts). This was not disclosed at the time, neither were the terms and conditions of the award.
The neighbour did not repair or replace the wall and it feel during the storms over Christmas. Part of my parents garden has now collapsed.
The neighbour is refusing to build a retaining wall and has become quite nasty, making demands on my parents to lower their garden level, not to build a new fence and help clear the mess created by the foundations on their side.
My parents' insurance cannot help because of the time that has passed.
Can anyone please advise on what may be the most appropriate steps?
