פירוש על יבמות 13:5

She who refuses the redeemer, is forbidden to marry his father, for she is looked upon like his daughter-in-law once his son (the original husband) dies and she must be redeemed. However, she is permitted to marry other relatives (of the husband). Some say that (she) additionally (cannot marry) any other relatives (of the husband). She is originally (not allowed to marry) any of the deceased husband's relatives (except for the redeemer), but if the redeemer refused her, then she is allowed to marry his relatives (This is how the Beit Yosef ruled). And always, if she refuses one of the redeemers, she is permitted to marry the other brothers.

If someone's brother was married to a sexually inappropriate female who had undergone levirate marriage, and he [the first man] had another wife, and afterwards the sexually inappropriate woman dies during the life of her husband, or she divorces him, or there was a young child that she objected to having that died afterwards, it is allowed for the other woman to undergo levirate marriage. But if she doesn't object to it in his life, and she objects after his death, than she does Chalitza (a way to get out of levirate marriage) instead of levirate marriage.

a minor female that is not forbidden for him marry, and he dies, or she refuses the preformance levirite marriage [with a brother of the husband], she is forbidden to the brother-in-law [in this case] and permitted to others without chalitza, if there are no other brothers [than the one]. and specifically her [the widow of the deceased], but her sister is permitted to him, even she is permitted to the remainder of brothers that she did not refuse [for the performance of levirite marriage].
