Any prenups I ever sign (if I get married) will result in no alimony or support whatsoever
You can't avoid child support.
Last time I got married, I had my then fiance sign a pre nup that basically stated "what I earn is mine, and what you earn is yours". Her GIRL friends urged her not to sign it, but she was in love and she did. Honestly, women ought to see pre nups as being VERY romantic, because it means she's marrying for love, not money. But nooooo, those women saw it as me being selfish.
But like my attorney told me at the time, "you can always give your wife things". Right. You can always give a woman gifts of cash or whatever throughout your days together. You can provide for her in your Will (along with the stipulation that you're still married and not divorcing at the time of death), so why automatically give away 50% of future earnings and increases in assets if you really must get married at all?
Along those lines, make it a point to keep your own separate bank account so that your monies NEVER get co-mingled. If you have a history of putting your earnings into a joint account, the courts will see those funds as belonging to both of you.
That goldigger in the article is just going after whatever she can legally get. We need more Guy Ritchies to happen to balance things out enough where women's groups will lobby to change the divorce laws. If ever.
