I believe the judge will want to see that both parties had qualified legal counsel at the time of signing the prenup, otherwise it might not be considered valid. I suppose with enough money at stake and enough animosity between the two parties, it is always advantageous to claim to not have understood the original contract. Worst case you lost a bunch of money in legal fees, best case you win big.
