Lean to on wall built on boundary line / party wall

A relative has concerns about new neighbours who are moving in the next week, and the prospective new neighbours after I queried it.

They are in a terrace house, and when they moved in over 7 years ago, there was an 8ft lean too off the kitchen housing the boiler and the rear door. No guttering overhangs to the neighbours side, the boiler vents though a vertical flue

The single skin wall which the roof rests on is built on the boundary line of the party wall, but if you imagine the party wall being 9 inches thick, the wall for the lean too, is on more on the neighbours side of the party wall. (indicated by the red line in the picture)

The relative also replaced and maintained all the wooden fencing which is in line with the lean to wall as the neighbour said it wasn't his fence.

The neighbours son who built it 25 years ago said he won't write something to say when it was done (not quite sure why he's a bit odd!)

Obviously there may be no issue at all, but is there any reason to be worried? You read strange stories of people fighting over a few inches of "land"

I'm guessing this lean to wall is a party fence wall and the PWA does not apply and the new neighbour can't just demand it be knocked down as it's built on the boundary (although they could use it to build their own lean to?)

If it's a party fence wall then the PWA does apply, but it's of absolutely no relevance here.

Surely if the new buyer bought the house with the extension already in place he's on dodgy ground expecting to be able to get it knocked down.
Thanks for the reply, the concern was that the buyer (who move in on Friday) had a builder round after they had put their offer in (the house needs a refurb top to bottom) and they made a comment about the wall, that it shouldn't be there!
