My uncle is unmarried. Since he is the eldest son all the properties are in his name. The house where I was born and family lives and other agricultural land plus house where he lives. He is taken care of by my father his only living brother(Only one other younger brother has also died few years back and was unmarried too). They had two step brothers whom I have never seen as no contact due to sour relations only heard. Since they were much older must have died but would be having children\grandchildren. In the event of my uncles death how would these properties be settled especially the home in which we live. Both properties were at that time bought with joint income\money of the three real brothers who were living as separate family unit from step brothers.
