My neighbours' manhole cover is in a sort of small courtyard on their own land, but they can only access it by coming into my garden, walking down my side passage and getting in through a gate on our boundary fence. That is because the people who owned their house before them built a small extension which comes right onto the boundary and has blocked off access to the side passage which would have originally allowed them to reach their manhole.
While they have a couple of windows looking out onto this courtyard (one of which is their downstairs loo), there's no door!
There was nothing in my deeds about this when I bought my house, and I stupidly assumed that the gate down my side passage leading from my garden into their property was a historical thing and was now unused. Both properties had been owned by the same family at one time, and I assumed it was just so they could easily move to and fro between their respective gardens.
But now I know the reality, I am very irritated that the neighbours think it is OK to use my garden to get to something on their own land just because their predecessors - and now them - aren't prepared to create an access door directly out of their own house.
Do I have the right to stop them trespassing on my property, and force them to create an external door in their own property? While they are perfectly pleasant people, I'd rather not have anyone trespassing just because their own house has been designed so badly.
I have searched all over the internet for an answer but can't find anything which specifically covers this issue.
Has anyone had any experience of this? Any thoughts would be gratefully received.
