If the fence is just - by a micro millimetre his side of the boundary then none. If it encroaches onto your side then you could take him to court. But, is there really any point? You say he 'erected a fence on our boundary' which implies it is his boundary too! Isn't it better to get on as neighbour's and not worry about a fence?

I've heard this before. Do yourself a favour and speak to someone from citizens advice. In a way its nice he paid for it, but without consultation seems a bit rude!!! I will pm you tomoorow my daughter works in a court!!

check the deeds of the house too. ours specifies a hedge not fencing/walls. You may find that the fence is actually in your favour. and as Mg says if it is only a small infringement then is it worth falling out over. you have to continue to live there and if you decide to move before them you have to declare disputes in the selling info.

I dont want to fall out with him, I just want to put in a few climbers!! He is notoriously volatile and I have been avoiding giving him anything to moan about, including damage to the fence! Ånyway, thanks to all

put your plant supports/trellis completely on your side and then the plants wont damage his fence, not that many would anyway. You could of course ask him if he has any favourite climbers and as long as you like them plant one of them to keep him sweet :o)

Legally, if you want to grow something up a fence, and the fence is not yours, you are obliged to provide your own, entirely separate, framework for the plants. The framework or support should not be attached to the existing fence if it belongs to your neighbour.

I think that covers what I wanted to know, thanks to all

I feel really sorry for you. Did you know this before you moved in?
