بسم الله الرحمن الرحيم
(1) The house which your father left shall be divided into 12 shares, after paying due rights preceding inheritance. Out of the total, 2-2 shares shall go to each brother while each sister shall get 1-1 share.
(2) It should also be divided among the heirs as per the rules mentioned above i.e. it should be divided into 12 shares, out of which 2-2 shares shall be given to each brother while 1-1 share to each sister.
The above-mentioned division of your father’s property is correct provided your mother died in the lifetime of your father or at the time of your mother’s death her mother, father were not alive and only these four sons and four daughters were the heir.
Allah knows Best!
