If father is alive and he wants to distribute his property among his children in his lifetime, then the best way is that he should keep share for him and his wife’s need and distribute the remaining shares among his sons and daughters equally i.e. he should give equal shares to his sons and daughters. However after the death of the father, a son gets double share and daughter gets single share. You may know the ruling of inheritance after the death of your father by writing the detail of Shariah heirs.
Allah (Subhana Wa Ta’ala) knows Best
