I own the house that I live in, but the house next door belongs to the council. The house next door is on a level which is 3 feet below than of my house. Years ago I voluntarily errected a fence on the top of the retaining wall ( the top of this wall is on the same level as my back door path), because the councils original wire fence had corroded, and I was concerned that without a fence some one could fall down to the level below. The fence is now in need of replacing, which I can't afford to have done since I am now a pensioner. But If I removed this fence it would then become a safety hazard as persons could easily step off my path and fall onto the path below. Who is reponsible for the replacement of the fence me or the council?
