The covenant marriage license requires pre marital counseling before a license is issued. It's not mandatory by any means but it is an option for those who do take their wedding vows very seriously. There are means of getting out for those who need that. There is no clause for irreconcilable differences though. There's at least a 3 day wait here. I agree that it should take longer to get married than what it is now. I think most churches have pre marital counseling for those wishing to marry in church.
I knew someone in Arkansas who met someone, married her and divorced her in less than 2 months. That's crazy, dumb and stupid.
