Is it obligatory for granddaughters to dispose of their inheritance to compensate their paternal aunts for their father's failure to divide their grandfather's estate according to Islamic law?

Your grandfather's inheritance must be divided among all his heirs, with the male receiving the share of two females, taking into account what your father or you paid from private funds during the purchase and construction of the houses. This division is obligatory to absolve your consciences and your father's, as you are living on property that belongs to others. The grandfather's estate must be inventoried and divided among his heirs, while being cautious of injustice and consuming unlawful wealth.
