A man who deposits coins for his son-in-law to purchase with them a field for his daughter, and she says "Let it be given to him [to do with whatever he wants]"—if she is betrothed, the trustee should do what was deposited with him [i.e. he has to buy the field]; if she is married, then she is allowed [to do this and the husband can do whatever he wants with the money]—words of Rabbi Meir. Rabbi Yose says: If she was a minor, whether she is betrothed or married, the trustee should do what was deposited with him.
