What will be the total shares for a family of five?

What will be the total shares for wife, 4 sons & 2 daughters? My father had a plot and later he sold to builder and have taken 4 flats & one shop. He had register the flat with all his 4 sons name (one flat each) and one shop to mother’s name. 3years before he sold one flat of my elder brother and after one month he expired. Cash is still there in Saving bank on my elder brother account and not yet utilize. Current situation as follows: First Son (my elder brother) – No flat for him. Only cash in his account appx. 8lacs Second Son (my elder brother) – one flat in his name with joint of my father name. ( Third Son (myself) – one flat in my name with joint of my father name. Fourth Son (my younger brother) – one flat in his name with joint of my father name. Mother – one shop in her name. Also have one flat in other area in my father’s name only and not yet transferred or registered to any other person. Before going to perform HAJ this year, my mother would like know the shares to be given to 4sons & 2daughters. Our queries are: 1. What will be the total shares for all. 2. Will the shares be divided from the all 4 flats cash which is registerd to all 3sons (elder bro is not having a flat, but having amount only in bank saving account) 3. How the shares can be calculated. For example suppose if total property is about 60lacs appx. 4. Is it necessary to give amount in hand to all before going to perform hajj or she can do after returning from Hajj. Waiting for your favorable reply. Salim. Allah Hafiz
