Since 1997, Louisiana has had a special version of marriage called Covenant Marriage. The intend and impact of Louisiana Covenant Marriages is that separations and divorces are harder to get. The legal requirements are found here:

A traditional marriage can be transformed in to a Covenant Marriage with some pre-contract counseling (faith based or secular counselors of your choice) and some paperwork representing a deeper commitment and promising to take certain steps to keep a marriage together before turning to separation or divorce.
Funny thing is, even through many men complain that it is too easy for wives to separate and divorce and rake them over the coals, less than 1% of men getting married since 1997 have opted for covenant marriage, and far fewer still have opted to have their existing marriages transformed into covenant marriages. It seems like many men are OK with being hitched, just not too tightly. Men concerned with divorce and separation being taken too lightly should consider Louisiana Covenant Marriage.
