The common aspects of a Jewish wedding are: the "ketubah" which is the Jewish marriage contract which establishes the rights and duties of the spouses and is signed by two witnesses, the "chuppah o huppah" which is the canopy of red and golden cloth under which the spouses exchange the ring and carry out the traditional breaking of the glass. It is divided into two phases: the "dedication or erusin", that is, the promise of marriage and the actual marriage which is called "nisuin".
