[If] one says to a woman: “You are betrothed to me on condition that I will give you two hundred zuz,” she is betrothed, and he gives [it]. “On condition that I will give [it] to you from now until thirty days” —- [if] he gave [it] to her within thirty [days], she is betrothed; if not, she is not betrothed.  [If he says:] “On condition that I have two hundred zuz,” she is betrothed [provided] he has [it]. “On condition that I will show you two hundred zuz,” she is betrothed [provided] he shows [it to] her. If he showed [it] to her on the table, she is not betrothed.

[If he said:] “On condition that I have a beis kor of land,” she is betrothed [provided] he has [it]. “On condition that I have [it] in a specific place” —- if he has [it] in that place, she is betrothed; if not, she is not betrothed. “On condition that I will show you a beis kor of land” —- she is betrothed [provided] he will show [it to] her. If he showed [it to] her in a valley, she is not betrothed.

R’ Meir says: Any condition which is not like the condition of the children of Gad and the children of Reuven is not a condition, as it says (Num. 32:29): And Moses said to them: If the children of Gad and the children of Reuven will cross ..., and it is written (ibid. v. 30): But if they will not cross zealously ... R’ Chanina ben Gamliel says: It was necessary for the matter to be stated, because otherwise, it is implicit that even in the Land of Canaan they shall not inherit.

[If] one betrothed a woman and said: “I thought that she is the daughter of a Kohen, and lo, she is the daughter of a Levi”; [or] “the daughter of a Levi, and lo, she is the daughter of a Kohen”; “a poor woman, and lo, she is a rich woman”; [or] “a rich woman, and lo, she is a poor woman” —- she is betrothed, because she did not deceive him.  [If] one says to a woman: “You are betrothed to me after I will be converted,” or “after you will be converted”; “after I become freed,” or “after you become freed”; “after your husband shall die,” or “after your sister shall die”; “after your yavam shall give you chalitzah” —- she is not betrothed.  Likewise, [if] one says to another: “If your wife bears a female, she is betrothed to me,” she is not betrothed. If the other’s wife was pregnant and her fetus was discernible, his words are effective; and if she bore a female, she is betrothed.
