In that a pre-nup protects the interests of both husband and wife in the opinion of many it is a good idea if not a must for everyone.
I had one with my wife and who in the world would have ever imagined addiction would be in the card after a few years. Usually falling out of love, losing interest, finding someone new, etc etc.
Alcoholism changed the game and changed all the rules. Without the pre-nup our young child's education/future would likely suffer because the AW would sip and p*i*s*s* money away like there no tomorrow, like she's been doing already before divorce. Not to mention tons of money not eaten by lawyers.
In the case when those marrying are in recovery there is a definite risk of relapse and insanity all over again.
What does logic and common sense tell you about pre-nup or no pre-nup ???
