[If] one [wife] said he died, and one said he did not die, the one who said he died may marry and collect her kesubah, while the one who said he did not die may not marry or collect her kesubah.  [If] one said, “He died,” and one said, “He was killed” —- R' Meir says: Since they contradict each other they may not remarry; R' Yehudah and R' Shimon say: Since both agree that he is deceased, they may remarry.  [If] one witness said, “He died,” and one witness said, “He did not die,” [or] a woman said, “He died,” and a woman said, “He did not die” —- she may not remarry.

[If] a woman went overseas with her husband and then she came and said, “My husband died,” she may remarry and collect her kesubah, but her co-wife is forbidden. [If] she was a Yisrael's daughter [married] to a Kohen, she may eat terumah; [these are] the words of R' Tarfon. R' Akiva says: This is not the way to deliver her from sin; [rather,] let her be forbidden from remarrying, and forbidden from eating terumah.
