Consider an agreement between heterosexual spouses entered into at the time of marriage in which, the woman spouse promises to notify the male spouse of any pregnancy and/or her intention to have an abortion, unless the woman in good faith believes that such notification would subject her to a risk of psychological or physical harm.

Should the law enforce such an agreement? Would a rule restricting women's contractual freedom to enter into such an agreement be based on paternalism or externality concerns?
