Hello my name is Alex and I will help you with this. Please note that I am a working Solicitor and may be on and offline as I have to attend Court and meet with clients, even at weekends. As such you may not get an instant response when you reply as this is not an ‘on demand’ live service, but rest assured I will be giving your question my immediate attention upon return. There is no need to wait here, you will get an email when I reply.
He can not claim the land. The land is registered to you.
This means that the land will always be yours. He would only be able to claim it by waiting 10 years then submitting a claim to the Land Registry, even then the rules have changed and they would write to you (assuming you still live there) and ask if you objected to him claiming it. If you did then his claim fails.
In any event you can do what you want on your side of the land. You can have the 6ft fence and your neighbour can not stop you.
He can not damage our cut down your fence in any way was this would be criminal damage
Can I clarify anything for you about this today please?
Please do take a moment to rate my answer before you go today.
