Thank you for your excellent prompt reply. We have just seen correspondence from the Landlord written from his firm's e-mail address. He is Partner and Head of Family Law and Litigation of a London based company. We googled him and found out he deals with landlord and tenant litigation!! Clearly this man will know the legally correct situation, so it appears to be intimidation against our young son. Does this affect the advice you have given and the way in which our son responds? For information, my husband is guarantor for the rent for my son and is an executive in the oil industry. Would it be a good idea for my husband to approach the landlord with our son's permission, stating that he is surprised at the response from the landlord. Thank you.
