Mishnayos Kesuvos Perek 7 Mishnah 8

If she has blemishes and she is still in her father’s house, as she has not yet gotten married, the father must bring proof that these blemishes appeared on her after she became betrothed, and therefore his field was flooded, i.e., it is the husband’s misfortune, since she developed the problem after the betrothal. But if she has already gotten married and entered the husband’s domain when her blemishes are discovered, the husband must bring proof that she had these blemishes before she was betrothed, and consequently the transaction of betrothal was a mistaken transaction. This is the statement of Rabbi Meir. But the Rabbis say: In what case is this statement, that a husband can claim to have found blemishes in his wife, on account of which he wants to void the betrothal, said? With regard to hidden blemishes. But with regard to visible blemishes, he cannot claim that the betrothal was in error, as he presumably saw and accepted them before the betrothal. And if there is a bathhouse in the city, where all the women go to bathe, even with regard to hidden blemishes he cannot make this claim, because he examines her through the agency of his female relatives. He would have asked one of his relatives to look over the woman he is about to marry.
