One who signs over his property to his sons must write: from today and after death; [these are] the words of R' Yehudah. R' Yose says: He need not.  [If] one signs over his possessions to his son to [take effect] after his death, the father cannot sell [them], because they are signed over to the son; and the son cannot sell [them], because they are in the possession of the fa-ther. [If] the father [went and] sold [them], they are sold until his death. [If] the son [went and] sold [them], the buyer has no share in them until the father dies. The father may detach [produce] and give to eat to whomever he wishes, and what [pro-duce] he leaves over detached [from the field] belongs to the heirs.  [If] he leaves older and younger sons, the older ones are not supported at the expense of the younger ones, nor are the younger ones fed at the expense of the older ones; rather they divide equally.  [If] the older ones married, the younger ones may marry. If the younger ones said, “We will marry just as you married,” we do not listen to them. Rather, whatever their father gave them, he gave.
