i think it's not so important whether people are lawfully married or not. they can live in civil marriage which is good, i think, because they will learn to live together, will pass domesticity, and they wouldn't have to obtain a divorce if they suddenly appear to not to cater each other. many families contract a marriage without consideration of the way they will live together, but then, qurrel just because of the tiny domestic discomfort which later leads to divorce. however, in my view, if they decide to give a birth to children it is better if a couple get lawful marriage in order so as to the child had legal father and mother.
