Does premarital intercourse make a marriage or does an agreement between the two people to become husband and wife in today's time make a marriage? So if for example, if someone had premarital sex but never signed documents or did a ceremony to be married but were boyfriend and girlfriend the whole time, let's say they maybe could have even been engaged but not officially married by law or by ceremony, and break up then they go off and marry by law and everything official different people is that their first marriage or their second marriage?
