We are planning to travel to Israel for the first time as a family, B"H. Do we need to bring our ketubah with us?
(I realize that this is probably a question for my Rav, but I am curious what the general answers might be.)
My understanding is that if you're moving there (or in the process of moving there and filling out paperwork), it helps to have a giant ton of documentation so the ketubah may be helpful. If you're just a family doing the tourist thing there for a few days, I can't see why a ketubah would be required, or even helpful. Best to leave it someplace self.
There are rumors of certain mikvahs in Israel that were concerned about single women trying to use them, and thus there was talk (I don't know if it became more than that) of demanding proof-of-marriage for a woman showing up at the mikvah. If you think this concern might be relevant, speak to a rabbi well-versed in the local Israeli issues -- or if you can't, contact www.yoatzot.org who will certainly be able to inform you of what mikvaot are in your area, and what experience to expect.
