2 points- this issue was touched upon in early July re an impinging fence and secondly, it's actually my aged mother's property.
Her nice newish neighbours put up a huge extension about a year ago. Mum gave them permission to site scaffolding on her property to do it. All home and hosed now BUT the guttering overhangs mum's property most of its 12' length at 8' height. It can't be moved in at all so the only 'option', removing it entirely, would cause a roof's worth of rain to cascade onto mum's (new) wooden fence. THEN, 6 months ago it was necessary for us to replace some wooden fencing a little further down the garden. 6' high panels, concreted posts. The wife dropped around in a friendly manner just to make mum aware that she felt the new fence impinged on her property by 'a couple of inches' at one point, and that the line of it wasn't straight (there's nowhere you can stand and assess this free of buildings or mature vegetation!). She just wanted to 'point it out'. She didn't ask mum to do anything about it, but the issue of their overhanging gutter has never been raised by either party. Now, mum is 'live and let live' about it all. Fine, but, to call a spade a spade, it won't be THAT long before it becomes MY problem if you see what I mean. I'm keen to avoid the spectre of a prospective buyer raising the issue and, god knows, maybe crash the sale as a result.
Anybody know what we can do? I know number one is to get the boundary surveyed, number 2 is to write them a letter BUT I know mum won't agree to that as in 'rocking the boat' which is fair enough but I want to know how long we have before the neighbours can claim an easement on mum's land if we don't officially do anything?
