I have four sisters out of which three are deseased and only one alive. I have three brothers, out of which three are deseased. One brother died after marriage and two brothers died unmarried. My father has not written any will in anyone's favour. The 7/12 of the land still reflects my father's name. After his death and the death of my mother, the property share will be transferred to his heirs. My question is:
1. Can sons and daughters of my deseased sister claim property share of their maternal grandfather (my father)?
2. Can my married sister who is alive claim property share of our father?
3. Can my elder brother's son and daughter claim property of their grandfather (my father) after death of their father (my elder brother)?
4. What happens to the property share of my two brothers who died unmarried?
I would like to know the ratio in terms of percentage that every legal heir would get in the above scenario. Can anybody advice me?
