An elderly lady has a son (in his 40s) who lives some distance away. She wanted to visit him where he lives.
The son apparently lives in a houseshare with 3-4 other gentlemen. I understand that he has an ensuite room and a shared living room and kitchen. The landlord does not live with them.
The son told his mother that his contract stipulates that he is not allowed any visitors at any time.
Is this even legal?
