Mishnayos Yevamos Perek 10 Mishnah 3

With regard to a woman whose husband and child went overseas, and witnesses came and said to her: Your husband died and afterward your child died, she does not require levirate marriage, as she had a child when her husband died. And for this reason she married another man. And if afterward they said to her that the matters were reversed, i.e., the child died before the husband, which means that she did require levirate marriage, she is therefore a yevama who married a stranger without ḥalitza and she must consequently leave her second husband. And with regard to the first child, the one born before they heard about the reversal, and the last one, born after they realized who actually died first, each of these children is a mamzer. Conversely, if they said to her: Your child died and afterward your husband died, and she therefore entered into levirate marriage, and afterward they said to her that the matters were reversed, which means she married her husband’s brother when there was no obligation of levirate marriage, she must leave her husband, and the first child and the last one are each a mamzer. If they said to her: Your husband died, and she married, and afterward they said to her that he was alive at the time of her marriage and he later died, she must leave the second husband. And the first child, born when her original husband was still alive, is a mamzer, and the last one, born after his death, is not a mamzer. If they said to her: Your husband died, and she became betrothed to another man, and afterward her husband came, she is permitted to return to him, as betrothal alone does not render her forbidden to her husband. Furthermore, although the last man, i.e., her betrothed, gave her a bill of divorce, he has not thereby disqualified her from marrying into the priesthood. She was never his wife, for the betrothal was invalid, and a bill of divorce given to the wife of another man does not disqualify her. This was taught by Rabbi Elazar ben Matya: The verse states with regard to priests: “Neither shall they take a woman divorced from her husband” (Leviticus 21:7), which indicates: And not one who was divorced from a man who is not her husband, e.g., the second man in this case.
