According to the gemaras at Yoma 18b and Yevamos 37b, Rav and Rav Nachman (and presumably other chachamin) would send representatives to cities a week before the rebbe intended to visit to find the rebbe a temporary wife, often for just one day. Several questions arise:
Did Rav and Rav Nachman give their temporary wife a kesubah and a get at the end of the marriage? Or was there a mutual understanding that the marriage would end as of a certain date, making a get unnecessary? Wouldn't such an understanding have to be in writing to establish proof that the temporary wife was no longer m'kadesh to the rav? See this link.
If the temporary wife was giving a kesubah, would she be entitled to the full 200 zuzim for a virgin and 100 zuzim for someone previously married?
If a virgin married Rav or Rav Nachman for one night without receiving 200 zuzim upon her "divorce," what would be the value of her subsequent kesubah?
