Hello, I am a solicitor with 20 years experience. I will try to answer this question.
Do you have an easement to cross his land to gain access to your land?
I do, but not in the exact location we have been using, in addition to the existing easement.
13 years will not be enough to gain an easement through customary use (ie by prescription) so you will be stuck with the old easement in terms of a legal right of way. I am afraid there is no such thing as a right to a view.
