Our road is semis, but of course the back gardens are all terraced...
I'll dig out the deeds, and see what they say about ownership, responsibilities etc.
The reason I'm asking is that I think the situation is the same as stevie888's and the right-hand fence is ours, the left-hand is the neighbours. We replaced a section of that fence where our builders wrecked it when doing an extension. Seemed only fair, and the neighbours were quite OK with it.
We now want to extend it on that side further down the garden. Their fence along that stretch is chain-link, ours will be wood panels.
Obviously we could just put ours right up against theirs, but I was wondering about removing the chain link if it made erecting ours easier, and they were in agreement.
But could it be storing up trouble for later? We would have put in a fence which was our property, and had an appearance which we want, but it would be the only fence along the boundary where normally they would be the fence owner, so I'm concerned that a future owner who didn't like the fence could replace it on the grounds that the deeds say it's theirs.
