(Mishnah): [If one said] 'this is your Get on condition that you give me 200 Zuz', she is divorced, and she gives;

[If he said] 'on condition that you give me within 30 days' - if she gave within 30 days, she is divorced. If not, she is not divorced.

R. Shimon ben Gamliel: A case occurred in Tzidon in which a man gave a Get on condition that she return his garment. She lost the garment. Chachamim ruled that she return its value.

(Gemara - Beraisa): If she did not give it before he died, R. Shimon ben Gamliel says, she gives to his father or brother, and she is exempt from Chalitzah or Yibum (the Get was valid).

The same applies to Kidushin. [If one said] 'you are Mekudeshes to me on condition that I give to you 200 Zuz', and he did not to give it before he died, R. Shimon ben Gamliel says, his father or brother gives to her, and she needs to do Chalitzah or Yibum (the Kidushin was valid).

(R. Yudan): [In the case in Tzidon,] she lost [the garment] through Ones. They made her like a Shomer Chinam who stipulates to be like a borrower (Tosefta Bava Metzi'a 8:9. This is why she must pay its value. However, she is not divorced, for the Tenai was to return the garment itself.)

Objection (R. Yosah): Do we come to teach that a Shomer Chinam can stipulate to be like a borrower?! Rather, we discuss when it was lost through negligence. [The Chidush is that] they made its value like the garment (paying is considered fulfilling the Tenai);

Note: R. Yudan holds that the Chidush is that even though he did not explicitly say that she will be like a borrower, this is understood; through accepting the Get with this Tenai, she accepted to be like a borrower (PF).

Chachamim say, this (the Reisha, a Tenai to give 200 Zuz) and the Seifa (a Tenai to return his garment) are due to Tanayim in Gitin. (In both cases, she may choose to give and be divorced, or not give and remain married. We explained this like R. MEIR SIMCHAH.)
