Bit of a complicated one... Hope someone can give me some answers.
We moved to our house about 4 years ago. We're now thinking of building a kitchen extension, but when I measured up I noticed that one of the side fences is in the wrong place, too far into our garden. I think it's about 30cm in our neighbour's favour. That's a lot of our garden they've gained and will make our extension an awkward shape.
I don't know when it was put there. The official plans clearly show that the boundary line goes straight from the joining wall of the houses, rather than a little way into our garden. Next door has only lived here for a couple of years longer than us.
Can we move the fence? Do I need a solicitor for this?
