Neighbours house behind ours is unoccupied and their back garden is overgrown with 6-7 foot high brambles which are now pushing into my garden and causing damage to both the fence and out buildings.
I've no idea who owns the property and neither do the other surrounding neighbours.
What's the worst that can happen if I access the neighbours garden and strim some of the brambles away from my property?
I also need access to do maintenance on an outbuilding on the boundry
