Just the conversation the two of you have about this little contract will tell you a lot about how your marriage is going to play out.
Would this language hold up in court? Doesn’t have to. If you get that far, you picked the wrong one despite yourself. But to surrender all recourse upon default is the best assurance you can give that you intend never to default – and it is one hell of an incentive not to!
But if your claim is that you’d gnaw off your own leg to escape this awful trap of a marriage – that there is no price too high to pay for your freedom – then do your gnawing in advance, in explicit, undeniable words.
Marry with this pre-nup and your marriage will last forever.
