Our neighbour died a few months ago and his house has remained empty since - we only found out from other neighbours and haven't seen anyone going in or out (although we're out all day so not inconceivable that people have been round, but in the past he didn't seem to have a huge number of visitors, other than his stepchildren coming over periodically to help tidy the garden - but only once or twice a year).
Anyway, in his garden is a huge eucalyptus tree which needs pruning - in the past, we've paid to have this done (as it's in our interests too and I don't think he could afford to pay for it himself) and he's just allowed the tree surgeons access through his garden. In addition to this, the boundary fence (which is his) is falling into our garden - we've had people round to look at putting in some concrete posts, but they've said they can only do this if we remove some of the ivy on his side of the fence as it's the weight of that which is pushing it over.
So ideally we'd like to get both these things done (and in the past, would have done - there's never been an issue agreeing them with our now deceased neighbour) - happy to pay for it, but the issue is agreement and access as they're both technically next door's. I'm assuming the house will get sold at some point but it really is in disrepair so the next of kin may choose to hang on to it in order to do it up - no idea.
How would I find out the next of kin to ask them? I could put a letter through the door but as I said, I haven't seen anyone going in so it may just sit there for ages with all the junk mail. Or am I being completely unreasonable and I just need to wait for someone to move in - whenever that may be - and if the fence falls down in the meantime, that's just tough.
Sorry, that was a bit long - just trying to anticipate any questions!
