Can anyone offer some advice please - my son and his girlfriend have recently moved in together. They paid one months rent and deposit up front, in cash ! they were not given a tenancy agreement (Ive only just found out about this) They moved into the room three weeks ago and every thing has been fine. Other people also rent rooms in the house. Today a woman arrives saying it is her house and that her ex partner rented out the rooms and had no right to. My son and fellow housemates have been told to move out immediately and you guessed it won't be getting any money back !! I think its a con but don't know what to do. It may be just a coincidence but all the people, apart from my son are from different countries and it was my sons girlfriend (from Slovakia) who paid the money out initially - so are they targeting vulnerable people who wont understand the law or am I barking up the wrong tree completely ? would appreciate input - the property is in Feltham, Middlesex in case this has happened before.
