We live in a ground floor flat and have upstairs neighbours. We have a back and front garden,and upstairs have got a massive garden at the back which is unattended and overgrown. Our flat belongs to the council as upstairs is private. They have their own access as we do. Our problem is,is that their access is now overgrown in the front and it looks horrific! Last year we went to clear the front which we thought was ours,to be told by upstairs that the landlady said its hers. I've asked is it possible to see the deeds but the landlady lives in bath, and we're in Wrexham. Apparently we only have access down this path to get to our back door and garden,and all down the side belongs to upstairs. We had maintained it for 3 yrs before being told it's not ours! Where do we stand as we seen a rat in their back garden today,we're a bit concerned as we have a dog. Who is responsible for the upkeep of this? As we weeded and cut branches outside our back door today,as were over hanging.
