Room of Seclusion
A Jewish wedding takes place under the Chupah, immediately after the Chupah ceremony the bride and groom adjourn to the Yichud room, which is a closed room where no people can enter. The door is locked from the inside allowing the couple to spend a few minutes together. This part of the ceremony is necessary for the final process of the Kidushin (betrothal). Jewish law forbids a man and woman who are not married to be secluded together in a room. Therefore entering the yichud room together is an act which symbolizes the couples newly married status.
Immediately after the Chupah ceremony the bride and groom are guided to a closed room where they stay together for a certain amount of time. The two witnesses that signed the Ketubah, must make sure there are no other people in the room with them. After the bride and groom enter the room, the witnesses remain outside the door for a couple of minutes. Today it is the practice that bride and groom utilize this time together to eat after their fast.
Who this Custom is Practiced by
This practice is common practice amongst all Ashkenazi Jews. Some Sefardi communities do not keep to this practice due to lack of modesty.
