If a scribe writes a get for a man

and a receipt [for the payment of kesuba] for a woman

and [the husband claims] he erred, and gave the get to the woman

and the receipt to the man

and they exchanged them [thinking, incorrectly, that they were giving each other the appropriate document]

and after some time [after the woman had remarried]

behold, the get is found in possession of the man

and the receipt is in the possession of the woman,

she must leave both [her new and ex-husband],

and all of these measures [listed in the previously] apply to her.

Rabbi Eliezer says

if it went out immediately [before she remarried]

it is not a get

if it went out after some time [after she remarried]

it is a get

[because] the first [husband] is not believed so far

as to revoke the privileges of the second.

If one wrote [a get] to divorce his wife,

then changed his mind,

Beis Shammai say

he disqualified her from [marrying] kohanim

and Beis Hillel say

even if he had given it to her on a condition

and the condition was not met,

he did not disqualify her from [marrying] kohanim.

If one divorced his wife,

then lodged with her in an inn,

Beis Shammai say

she does not need a second get from him

and Beis Hillel say

she needs a second get from him.

When?

When she was divorced subsequent to nisuin (the second step of the matrimonial procedure)

and they concede that if she was divorced from eirusin (the first part of the matrimonial procedure)

that she does not require a second get from him

as his heart is not close to her.

If one married a woman [based on her having] a 'bald' get

she must leave both

and all of these measures [listed in the previously] apply to her.
