they live in my house and share the kitchen and bathroom with me
they do go outside but: I allowed them to fit a lock on their bedroom door and the refused to give me a key. Also the girl's parents are also lodgers here and as far as I know they plan to stay. The parents came first, a few months later the young couple moved in.
Only t the young couple. The parents were very annoyed and said they would be leaving, but I did not give them notice to quit (had no reason to) and know they are finding difficult to get another place in the same area
I asked if it would be possible to get the door off its hinges (after end of notice to quit) at a time when one of the is in and the door is open and also to remove their furniture to the patio
