So firstly I know I can just ask my neighbours, but we don't particularly get on well, as a few summers ago they were throwing over cat poo, over the fence, on to my children's summer house! Wasn't even from my cat so obviously my husband (rightly so) got very angry, hence why we don't really talk.
So when I look out my back door, the fence to my left... is it mine or the neighbours? The winds making one of the posts very loose and I'm worried it's going to fall.
The house is only 7 years old and we are the first to own it. The developers never told us (they were as useful as a chocolate teapot). I'll be making a call to them but I'd just like to hear what is your view as I know some people say the left side is yours?
When the neighbours and I confront id also like some poo to hit them with too 
Thank you
Sorry about the drawing, quickie before the school run.
