Do I still have the right to 50% of the company and its management after my father's death, or do all the company's profits go to the family and they have the right to choose the new manager?

If a father gifted 50% of his company to his son in exchange for managing it, and the father died:

1. If the father had other children and did not gift them similarly, then the gift is unjust, and this percentage must be included in the estate. 2. If he had no other children, then the gift is not purely gratuitous but in exchange for management, and the partnership is dissolved upon his death. 3. The partnership is dissolved upon the death of one of the partners, according to the majority of jurists. 4. The shares gifted by the father to the son revert to the estate, and the heirs have the option to divide the company or to maintain it and appoint a manager (whether the son or someone else) for a wage. 5. If the heirs agree to the son's management and to give him half in exchange for his management, then that is a new partnership among them.
