Essentially the issue is this: our neighbours have started putting their bins on our lawn. The front lawns were previously shared but were divided in two in the deeds. They've started the process of turning theirs to an extension of their existing driveway, meaning that they no longer have a lawn area on which to put their bin.
So they've started putting it on our lawn instead, expecting us to put our bin on our own driveway. We're blocked so that they won't be. I've started to move their bin back to their own driveway but the bin keeps reappearing every week on our lawn!
So AIBU and, if not, what can I do to stop them doing this? It's becoming incredibly annoying!
