Baha’is are permitted to marry non-believers but they should insist on observing the Baha’i marriage ceremony and should also not object if their non-Baha’i partner wishes to observe the marriage ceremony of his or her particular religion. Civil marriage is generally practised amongst the Western believers, but in most of the East it is unknown.
