@ShakeNvacStevens I think I must have been unclear.
I was NOT trying to say if it is more often the fault of the man or the woman.
I was simply saying that, unlike in other jurisdictions, in England the pre-nups are not fully binding (the risk of the courts deciding something different is much higher than elsewhere), and the financial settlement does not change much if one party cheated or did something despicable.
Why is this important? Because someone with more assets than their partner might think: wait a second, the English legal system basically gives my partner an incentive to divorce me and take a significant share of my assets. Something's not quite right! Note that this applies regardless of gender.
For couples who build their wealth together it's one thing, especially if it's the woman who sacrifices her career more to allow his to flourish.
But for couples who start with significantly different assets and/or don't have children together (as would have been the case for the couple in their 50s I mentioned) it's different.
It doesn't matter how many cases you have witnessed where you scratch beneath the surface and it's also or mostly the man's fault.
It doesn't matter whether it's the man's fault in 20% or 50% or 80% of the cases.
What matters is that the English legal system gives the other party an incentive to divorce just to get a significant share of the assets.
This risk can be reduced greatly in other jurisdictions, but not so in England.
And this puts some people off.
