Is the legally documented waiver of property to minor heirs considered a valid gift or a bequest, especially when the inheritor managed it for them during his lifetime?

What the father did was a gift that was taken possession of and seized, and in contracts, the meaning matters, not the words. Some scholars hold that it is forbidden for a father to single out some of his children for a gift unless there is a valid justification. What the father gave to his son becomes effective upon the father's death, if he died before making any changes, and if the gift was not made during his fearful death illness. In such a case, the gift is affirmed for the recipient. What is most likely is that the gift is effective, and one can refer to the judiciary.
