10 A father may cancel his daughter's vows until she comes of age, that is, when [she reaches the age of] twelve years and six months, provided that she has not married. A husband may cancel his wife's vows. What is the process for cancellation? He says three times: "cancelled" or "absolved" or any other language that indicates total abrogation of the vow, regardless whether he says this in her presence or not in her presence. However, language of "nullification" is not valid for a father or husband. Also, they can only cancel the vow within the day they heard it. That is, if they heard the vow at the beginning of the evening, they may cancel it all night and the entire following day. If they heard [the vow] close to the time that the stars appear, they can cancel it only until the stars appear. Beyond that time they cannot cancel it. On Shabbos, he should not say to her: "It is cancelled for you" as [he would say] on a weekday, but he should cancel it in his heart, and say to her: "Take and eat" or some similar expression. If the father or the husband at first said that he is satisfied with the vow, although he did not say so explicitly, but said something that indicated his satisfaction, and even if it was only in his heart that he thought that he is satisfied by her vow, he can no longer cancel it. (If she made the vow conditional upon some act, see Shach 234:45.)
