Share in self acquired property.

I have a flat bought by me in Delhi. now since last 4 years i and my wife are living at my native UP. i have 2 sons. one is living with me in UP and another son who is in indian coast guard living in my Bangalore's flat. and they are not giving any rent from last 4 yrs. now i have said him to leave my flat because we want to give it on rent to somebody else for life living.but he is not ready to leave the flat.in this case what should i do with them. Can he get any kind of share from my self acquired property if i dont want? Can i transfer my flats to my younger sons name if i want? Kindly advise me I am very helpless.
