While the ceremony is a sham, the marriage is real between two Jews, therefore a get would be needed upon divorce. Otherwise, the persons would still be halachically married to each other & any subsequent relationships would be huge aveirot, esp. for the woman who would become an agunah & any offspring with another man would be mamzerot. If you are in this situation, please seek resolution through an appropriate rabbinic council. B'Hatzlacha!
