What is the ruling on transferring a commercial shop investment license from the father's name to his sons' names, if the shops are not owned by the father but he possesses the right to invest them, and the sons claim that they spend on their father from its income after the father has become old?

Sons are not permitted to transfer their father's license without his consent, even if they spend its proceeds on him. Similarly, a father is not permitted to designate his sons for the relinquishment of a license that holds financial value, unless there is a legitimate religious justification. This is because preferring some children over others without a valid reason is religiously forbidden.
