Yevamot 53A

יש זיקה, ואתאי חליצה אפקעתיה לזיקה. ורבנן סברי: אין זיקה. מעיקרא אילו אמר לה: ״התקדשי לי בזיקת יבמין״, מי לא מהני? השתא נמי מהני.

that the levirate bond is substantial, and this betrothal is based on the levirate bond. And in this case, the ḥalitza comes and releases the levirate bond. Therefore this type of betrothal does not acquire the ḥalutza. But the Rabbis hold that the levirate bond is not substantial, that is, the bond itself does not create a connection between the yavam and yevama, and that in general, levirate betrothal acquires a yevama as a form of betrothal unrelated to the levirate bond. And consequently, at the outset, if he had said to her: Be betrothed to me by the levirate bond, would this not be effective? Now too, after ḥalitza, even without the bond, it should likewise be effective.

רב שרביא אמר: בחליצה כשירה, אי דאמר לה ״התקדשי לי בזיקת יבמין״⁠ — כולי עלמא לא פליגי דלא מהני. והכא בחליצה פסולה קמיפלגי: מר סבר חליצה פסולה פוטרת, ומר סבר חליצה פסולה אינה פוטרת.

Rav Sherevya suggested a different point of dispute and said: In a case when the woman performed valid ḥalitza, if he later said to her: Be betrothed to me by the levirate bond, everyone agrees that it is not effective, as there is no longer any bond. And here, they disagree with regard to one who performed invalid ḥalitza. One Sage, R' Yehuda HaNasi, holds that invalid ḥalitza exempts her from the levirate bond and disqualifies her from betrothal as a yevama. And one Sage, i.e., the Rabbis, holds that invalid ḥalitza does not fully exempt her, and some element of the levirate bond remains intact and she can therefore be betrothed with the levirate bond.

רב אשי אמר: דכולי עלמא חליצה פסולה אינה פוטרת, והכא ביש תנאי בחליצה קמיפלגי: מר סבר יש תנאי בחליצה, ומר סבר אין תנאי בחליצה.

Rav Ashi said: Everyone agrees that invalid ḥalitza does not exempt her and does not entirely nullify the bond. And here they disagree as to whether a condition is effective with regard to ḥalitza. When the yavam states he is performing ḥalitza on the condition that the yevama give him 100 dinars, For example: is this condition effective and therefore the ḥalitza is nullified if the condition is not fulfilled? One Sage, i.e., the Rabbis, holds that a condition is effective with regard to ḥalitza. If the yevama fails to comply with the condition, the ḥalitza is ineffective and she can still be betrothed with the levirate bond. And one Sage, R' Yehuda HaNasi, holds that a condition is not effective with regard to ḥalitza, and therefore the ḥalitza is always effective, and the subsequent levirate betrothal is ineffective.
