I put lights on the fence posts on my side of the garden.... my neighbor has smashed them off

[Emz2019]

We don’t get along with the neighbor.... so the fence is 6ft high and the posts are on my side, we put some solar lights on the fence posts at the top, the neighbor would see maybe 5mm of the top of the light as the posts are quite a lot shorter than the fence boards. Anyways she’s leant over into my garden and smashed them all off. Is this criminal damage? Or is it ok for her to do that if this is her fence? Even though the lights are in my garden and not at all in hers

The fence goes on the boundary so the posts have to go inside the boundary. The alternate is putting the posts on the boundary so the fence is inside giving you a (slightly ) smaller garden.

Also as far as I'm aware it's the polite thing to do.

Traditionally the owner gets the worst side. It may well have become less the norm recently but that's how builders used to operate.

Are you sure it wasn't a cat?
That jumped up and smashed each light on a 6ft fence??

If the NDN is indeed the owner of the fence, the fence may be entirely within the boundaries of her property and the actual boundary line to the OP's side of the fence. There are no set rules on these kinds of things. Where neighbours share fencing costs the fence will usually follow the boundary line but that assumes shared responsibility for the boundary structures. The Ozp needs to check the title register and title plan and see what the register states about the boundary, etc and see if there are any markings on the plan. Where there is nothing, the presumption is that the boundary is a shared responsibility. But in such a case if neighbours don't agree to share costs, then the person paying should put the fence within their boundary line. Hth.

You shouldn't attach anything to someone else's property without their permission. Yes the NDN could have just asked the OP to remove the lights but maybe this was just yet another thing the OP has done without asking and the thin end of the wedge for the NDN?
