Tues Nedarim 86

The Gemara is finding a case how can she Assur her work for after she gets divorced, since right now it's something that she doesn't have a power over. We cannot compare it to even selling a field he gave up for collateral, though it's not in his hands anymore, since he has the right to redeem it and it will be in his hands. Even if they stipulated that he can't redeem it up to ten years, but eventually it will be in his hands. However, a woman has no way to have herself divorced in order that her work may become her's.

Ran asks: the woman has the ability to say she doesn't want to work for the husband and she won't receive any food from the husband. So we see she has a way to force having her salary in her own hand.

Ran answers: that only works for what she needs to work (with making wool) for supplementary income. That the husband doesn't need to worry about, since it's simple for her to keep that money separate. However, the problem here is that she also Assurs the housework that she needs to do, which is a problem for the husband, therefore he needs to Matir it. However, the Gemara has a problem, since there is no way for a woman o get charge of that since she cannot opt out even if he doesn't feed her.
