Is marriage without ketubah considered marriage, concubinage, or kiddushin she’einah re’uyah le’biah (marriage that cannot be consummated)? I have read a number of different things suggesting each of the three. In the discussion herehere about concubinage, it was suggested that concubinage=simply marriage without a ketubah, so marriage without a ketubah=concubinage. But I have also read that marriage may be contracted without a ketubah: either through biah or a ring. Finally, I have read one source suggesting that the couple may not have relations without a ketubah; thus, a marriage without a ketubah is a kiddushin she’einah re’uyah le’biah. Which is correct?
