LONDON: Prenup enforceability now the law of the land?

Radmacher v. Granatino
The London Court of Appeals has decided that the prenuptial agreement between German heiress Katrin Radmacher and her French born husband Nicolas Granatino, an investment banker, will be upheld.
The couple executed a prenup in 1998 when they married but 8 years later when it was time to divorce, hubby Nicolas wanted to do away with the prenup. Presumably, he thought he would get away with it since England pretty much frowns on prenups as a general rule and treats them as toilet tissue. But times are achanging. And it seems that the rule of law could undergo a structural change as to the enforceability of prenups following this ruling that the Radmacher/Granatino prenup is a good pre-marital contract. This would bring English law up to speed with German, French and American law on the issue of prenups. In all of these jurisdictions, if a prenup is fair, it generally will be enforced.
I think this is a good move by the English courts, don’t you? What do you think? Should prenups be enforced even if a rich spouse will walk away from a marriage and leave his/her less affluent spouse in the poor house – which is pretty much what happened in the Radmacher – Granatino case?
