Looking for some advice on behalf of my parents. In the recent storms a wall behind their house blew down into their back garden, damaging some of their property. To explain - there is my parents garden, then a trellace and my parents fence which were both partially knocked down/broken by the wall, then a little gap where plants grow, then the wall and then a private car park which backs onto a housing estate (where this house is). This now means that there is free access to my parents back garden which is causing my mum a huge amount of anxiety. They have checked on the land registry website and it shows that this portion of wall on the edge of the car park belongs to house X.
They have spoken to their insurance company who have advised they write and ask the people at that address to fix the wall and remove the bricks. They have told my parents they are not allowed to touch the bricks as the bricks are not their property and that they also cannot leave them on the other side as it would be tresspassing as it's private land. My parents wrote and asked them to make contact by a set date but this date has passed with no contact. The insurance company say the next step is to take them to court. My parents would really like to resolve this without going to court. The other concern is that if they did take them to court then my parents may end up paying for the costs if it didn't go their way, which they cannot afford. My parents are good people and don't want to make anyone's life difficult - perhaps it's a sitiation where the other party cannot afford to fix it, but my parents need them to make contact at the very least to discuss it and to try and find a solution. They have mobility and health problems and wouldn't feel confident just walking round for a chat.
I'm just wondering if anyone has any experience with something like this or can offer some advice?
