ג מי שנתחייב לחבירו שבועה בב"ד ואמר לו השבע לי בחיי ראשך והפטר או השבע לי בחיי ראשך ואתן לך כל מה שתטעון אם קנו מידו אינו יכול לחזור בו ואם לא קנו מידו יכול לחזור בו עד שיגמר הדין נגמר הדין ונשבע כמו שאמר ליה א"י לחזור בו וחייב לשלם וה"ה למי שנתחייב שבועת היסת והפכה אם קנו מידו או אם נשבע זה שנהפכה עליו א"י לחזור בו וה"ה במי שלא היה חייב שבועה ואמר אשבע לך שבועה אם קנו מידו א"י לחזור בו ואם לא קנו מידו אע"פ שקבל בב"ד חוזר עד שיגמור הדין וישבע: הגה מי שמחוייב לישבע ואמר לפני ב"ד איני רוצה לישבע אלא הריני משלם ויצא חוץ לב"ד אינו יכול לחזור בו דזה הוה גמר דין דידיה ויש חולקין (ע' בטור) מי שנתחייב לחבירו שבועה דאורייתא ואמר לחבירו השבע וטול ונשבע בלא נטילת חפץ לא יוכל לחזור בו (ב"י):
3 One who was under obligation to his fellow to take an oath in Court and [the latter] said, 'Swear to me by the life of your head and be exempt,' or 'Swear to me by the life of your head and I will pay you whatever you claim,' — [then] if they made a formal agreement with him by means of a Kinyan, he cannot retract; and if they did not make a formal agreement with him by means of a Kinyan, he can retract until the legal proceedings are closed. Once the legal proceedings are closed and he took the oath as stated to him [by his fellow-litigant], he cannot retract and is obliged to make payment. Likewise one who was under obligation to take an equitable oath and transferred it [the oath] to his opponent, — [then] if they made a formal agreement with him by means of a Kinyan or if the party to whom it was transferred took the oath, he cannot retract. So too, one who was not obliged to take an oath and stated, 'I will take an oath,' — [then] if they made a formal agreement with him by means of a Kinyan, he cannot retract; and if they did not make a formal agreement with him by means of a Kinyan, although he accepted in [the presence of] the Court [to take the oath], he may retract until the legal proceedings are closed and [only thereafter] he must take the oath. Rema: One who is under obligation to take an oath and stated before the Court of Law, 'I desire not to take an oath, I am prepared to make payment,' and [ then ] left the Court of Law, — [ the law is that ] he cannot retract for this is regarded the close of his legal proceedings. Some [ authorities ], however, differ [ with this view ]. One who was under obligation to his fellow to take a Biblical oath and he said to the latter, 'Take an oath and collect,' and [ then the latter hurriedly ] took an oath without holding a [ sacred ] object, — [ the law is that ] he [ the defendant ] cannot retract.
