What do you advise regarding reasonable sleeping arrangements in the case of chuppat niddah (where halakha requires that one observe the laws of yichud)? This will be relevant for our upcoming wedding.
Mazal Tov on the upcoming wedding. Regarding sleeping arrangements—I take the position that even if the two of you are sharing an apartment, it is not yichud if you are in separate rooms with a closed door between you (some require that the woman’s door be locked. I do not require this). (See Chazon Ish Even HaEzer 34:1)
