Bava Batra 139: The Strength of an Undocumented Loan

A new mishnah (from the bottom of 138): A father who gives his land to his son, while retaining the rights to the produce for himself, until after his own death. Plus, once the produce is detached from the ground, it is the father's, while I still attached, it's "part of the land," and owned by the son who owns the land. Note that funds that are held for minors cannot be used to provide for the adults, and vice versa. The same applies for adult and minor daughters, with one key caveat that is a difference between the sons and daughters in this capacity. Also, the case of a woman who borrows money, uses it, and gets married -- what accrues to her? And what rights might the husband have? Is the husband like a buyer or like an heir?
