Last weekend, my landlord came to me to explain me that he has a delicate situation with his wife. In the moment, he is not living here. I live in their house in one of their annex that has its own entrance. I signed contract with him from 19.10.2012 until 28.02.2013. What he is proposing me is that in order to show to his wife and wife&#39;s lawyer that he is living here, he wants me to give him access to my flat and then he will just stay a couple of hour everyday and then he leaves. Also, he wants to introduce a bed to pretend he is living here officially. I had 2 conversations with him and the last one I told him that I did not like the idea of living with another person and that I dont want to be in the middle of his situation. So I told him that what would happen if I say no, he told me that then he can cancel the contract, and that I wouldnt have any rights as tenant. I am from venezuela, so I could not make any assumption because I dont know the german law. What I want to know is what my rights are as a tenant, so I can tell him what the real conditions are. I know he has the right to move in but I heard he needs to give me a notification 3 months in advance if he wants to do so. 3 months in advance is the time I need until the contract is over.  Thank you for your attention and I am waiting for your help.  Best Regards,  O.A
