Advice please, as you look at the garden from inside the house on the right side two panel and fence post has collapse and leaning towards my side. Spoke to neighbour (new neighbour a bit weird) they say it's my responsible I said I doubt it as the previous neighbour has repaired it.
My question who responsible for that.
Just because your neighbour repaired it before doesn't necessarily mean it is their fence.
You need to dig out the plans showing your plot when you bought the house. Many of these have little T shapes drawn on the fences, the way the stalk of the T faces defines who owns the boundary (I can't remember which way round, but should be easy to find on the internet if your plan does show these things). Or the deeds to the house may specify whether or not the boundary is shared.
I've had various different neighbours. In one case the neighbour insisted it was my fence and I couldn't disprove it - it was only a couple of panels so I just coughed up. In my last house fences on both sides needed repair at various stages. I think the deeds said shared fences, but in both cases (i.e. both neighbours) we just paid half each. Same in my current house - it does depend on how well you get on with your neighbours.
So the neighbour fixed it last time, and you think the neighbour should sort it again? Isn't that just a teensy weensy bit selfish on your part?
Not necessarily, no - it depends whose responsibility it is to mend the fence.
