Mishnayos Kesuvos Perek 7 Mishnah 4

With regard to one who vows and obligates his wife not to go to her father’s house, when her father is with her in the same city, if the vow is to be in effect up to one month, he may maintain her as his wife. If the vow is for two months, he must divorce her and give her the payment of her marriage contract. And when her father is in a different city, if the vow is to be in effect until at most one pilgrim Festival, i.e., until the next pilgrim Festival, he may maintain her as his wife. Although the wife often visits her parents during the Festival, she is capable of refraining one time. For three Festivals, however, he must divorce her and give her the payment of her marriage contract.
