Does he share any facilities with you, bathroom, kitchen or any living accommodation or is his accommodation self-contained? Thank you.
I am sorry for the delay. I had a client.
The use of the front door is not relevant.
What is relevant is whether you are a member of your family share a kitchen living room or bathroom with him which you don’t.
If you did, then he would be classed as an excluded occupier and you would only have to give him reasonable notice to end the letting you don’t need a court order. When the notice expires (usually one month) you could have locked him out provided you give him his belongings back.
He is however allowed you with basic protection because he lives in your home but doesn’t share any living utility space with you or your family. Hence, you can’t simply lock him out, if he will not leave when given notice, you will have to go to court and get a court order to evict him.
