114 Gittin 8/1-4

(1) [With regard to] a husband who throws a bill of divorce to his wife and she is in her own house, or in her courtyard, she is divorced. If he threw it to her within his house or within his courtyard, even if it is with her in bed, she is not divorced. [If he threw it] in her lap or her basket, she is divorced.

(2) If he said to her, "Take this promissory note," or she finds [a document] behind him, and she reads it behold it is her bill of divorce, it is not a [valid] bill of divorce, until he expressly says, "Here is your bill of divorce." If he put it into her hands while she is asleep, and when she awakes she reads it, and behold it is her bill of divorce, it is not a [valid] bill of divorce until he expressly says, "Here is your bill of divorce." If she was standing in the public domain and he threw it to her. [If it fell] closer to her, she is divorced; closer to him, she is not divorced. Halfway [between the two], she is divorced [in some respects] and not divorced [in others], i.e., her divorce is a matter of doubt.

(3) The same is true of betrothal, and the same is true of a debt. If one's creditor said to him, "Throw me [the payment of] the debt due to me," and he threw it to him: [if it fell] closer to the lender, the borrower is exempt; closer to the borrower, the borrower is [still] liable; halfway [between the two], they split it. If [a wife] was standing on the roof, and [her husband] threw [a bill of divorce] to her, once it reaches the airspace of the roof, she is divorced. If he is above and she is below and he threw [the bill of divorce down] to her, once it leaves the [airspace] of the roof she is divorced. [At that point,] were it to be erased or burned, she is [still] divorced.

(4) Beit Shammai say, "One may release his wife with an old bill of divorce." Beit Hillel prohibit this. What is an old bill of divorce? Whenever he is in seclusion with her after he wrote it for her.
