I thought I was the perfect neighbour to my NFH (neighbours from hell) for 20 years. Fed the cats, took in parcels, kept a spare key until this year when they built a, very tiny, side extension. I objected to a large window looking into my garden/conservatory and it all kicked off from there.Party Wall Surveyor was employed and now they seem hell bent on seeking revenge. They wrote twice to me in May threatening to take down the fence and realign it to their advantage. They say I had moved it several years ago! I did not move my fence which forms the boundary. From then followed a stream of accusations none of which is true, they even insisted the title deeds showed the space between both properties to be equal when its patently obvious my side is wider than theirs. My side forms the entrance to the front door of my house, theres is rear access. I must mention that my neighbour worked in the Planning Dept of our local council and now works in a similar capacity in a neighbouring borough. I felt very intimidated by these threats so I rang the police for advice (they logged the call) and from there I got a solicitor through my insurance company (I paid extra for Family Legal Protection) but they will only cover me for Trespass and Nuisance NOT a boundary dispute. All my evidence proves they are wrong and if they tried to claim they are doomed to fail as my solicitor constantly keeps reminding them. That doesnt deter them as they know I intend to sell my house and the whole point of this is to cause a dispute which they have now done and apart from the stress I am now unable to confidently sell my house with this dispute hanging over it- I of course would declare the dispute they have created but this puts the possibility of a sale under threat. Two weeks ago the neighbour followed my partner to his car accusing him of Criminal Damage where he supposedly cut down his climbing plants from the fence - the shrub was mine! My partner has not been well lately and was very shaken by this harrassment - luckily he kept his cool. I spoke to the police about this and again they logged the call. Anyway, sorry to go on but as I stand they refuse to end the dispute. Latest thing is I received a letter telling me they need to repair a chimney and want to put scaffolding on my property for 3 weeks and will move the fence if needed. My solicitor has told me to refuse ........which I know could end in a court request for access. Would appreciate any advice-of course the usual reaction is I am told 'they cant do that' but believe me they can!
