Kesubos 6:7-7:1
Kesubos 6:7
If a man deposits money for his daughter’s dowry with a trustee (after which he dies) and the bride tells the trustee that she trusts her husband, the trustee must nevertheless follow the father’s instructions (and not give the money to the groom). This represents the opinion of Rabbi Meir. Rabbi Yosi says that if the dowry is only a field and she wishes to sell it, it is sold immediately. This is only the case when the bride is a legal adult; a minor cannot make a meaningful act (so the father’s wishes continue to be followed).
Kesubos 7:1
Let’s say that a man made a vow banning his wife from benefiting from him. If it is for up to 30 days, he may appoint an agent to take care of her needs. If it is for longer than this, he must divorce her and pay her the value of her kesubah. Rabbi Yehuda says that an Israelite can support his wife through an agent for one month but he must divorce her and pay her the kesubah in the second month; a kohein may support his wife through an agent for two months but he must divorce her and pay her the kesubah in the third. (A kohein is given extra time because he is not permitted to remarry a woman he has divorced.)
