During the life of a person, the distribution of their estate among their children is fundamentally considered hiba i.e. a gift and the person giving hiba has full right and control in how they want to distribute it. It is upon their discretion to distribute and after the children have taken complete control and ownership of the gifts given to them, that division will remain valid after the death of that person.
However it is considered absolute transgression and oppression if one purposely deprives a rightful heir of their due share. Regarding this issue fuqahah have clarified the ruling by recommending such a division during this person’s life, that after their death if the heirs were to revisit the topic of this distribution, the original division remains valid and just.
