Inheritance

Q: I am preparing my will. My dad is alive. I have 2 daughters, 1 son and a wife. Due to past family issues, my dad has entrusted me to 100% of the family business. In my heart and conscience 2/3 belongs to my two brothers. My brothers are not of stability. Presently I take care of all their requirements. Please advise how I would fulfill my obligations of inheritance.
