Hello, welcome to the website. My name is***** can assist you with this.
Neither the neighbour nor the unknown man can do this.
It's trespass to your property if they've cut down property on your territory.
What about the council or whoever he has asked to do the other tree Is it definite they cannot do work I don't allow. he says it sheds his garden for 3 hours a day
I mean shades!
If it's overlapping into their land, they can chop that overlapping part off. But not the bit in your land.
Having shade is no reason to chop down your trees!
