Mishnayos Kiddushin Perek 2 Mishnah 3

If one said to a woman: Be betrothed to me on the condition that I am a priest, and he was found to be a Levite; or if he said: A Levite, and he was found to be a priest; or if he said: Be betrothed to me on the condition that I am a Gibeonite, a people prohibited by rabbinic law from marrying into the congregation, i.e., from marrying a Jew of fit lineage, and he was found to be a mamzer, who is prohibited by Torah law to marry into the congregation; or he said: A mamzer, and he was found to be a Gibeonite; or if he said: Be betrothed to me on the condition that I am a resident of a small town, and he was found to be a resident of a large city; or he said: A resident of a city, and he was found to be a resident of a town; or if he said: Be betrothed to me on the condition that my house is close to the bathhouse, and it was found to be far; or he said: Far from the bathhouse, and it was found to be close, she is not betrothed. Or if he said that she is betrothed to him on the condition that he has a grown daughter or a maidservant, and he does not have one, or on the condition that he does not have one and he has one; or on the condition that he has no sons, and he has sons, or on the condition that he has sons and he does not have sons, then she is not betrothed. And in all these cases, despite the fact that she later stated: I intended to become betrothed to him nevertheless, whether or not he fulfilled the condition, she is not betrothed. And similarly, if it was she who misled him by making the betrothal conditional upon a statement of hers that turned out to be incorrect, the betrothal will not take effect.
