There’s a no-man’s land back passage running behind three terrace houses (1,3,5). We own no. 1 (recently bought) our neighbours own 3 and 5 (yes they own 2 houses!)
Neighbours have put a locked gate on the passage and claimed it as their own. They store their bins and bikes back there- including in the space behind our garden.
We asked if we could store our bins there too - there’s space for at least 2 more bins without blocking the way. (Also our garden is much smaller than theirs and we have three small kids- they have one 15 yr old).
Neighbours have said no. They have said since they’ve been using this passage as theirs only for years (because they put a locked gate on in) , it’s now legally their property and we have no right of access and they are not willing to share.
Do we have any leg to stand on here? I’m guessing not but thought I’d consult the collective wisdom of mumsnet..
