Okay, let's hypothesise. I mean really hypothesise.
Two people trot up the aisle together and take a vow that they'll endow one another with all their worldly goods.
25 years later, the man (who's done pretty well) skedaddles off to Bermuda. He's been a completely absent parent throughout the marriage. Probably a serial adulterer too. In the run up to moving off to Bermuda, he stashes a lot of the joint assets away ... claiming joint property is not joint property ... you know the drill.
Rather unfairly, you have to picture the man as having a midlife crisis. I'm talking botox and shapely young girlies here.
The woman is worried about her children. The ones she raised. The man is off on a yacht with a bevy of trophies.
If the woman wanted the money to make sure it passed to her children and grandchildren, rather than the children and grandchildren of 1000 bimbos, would you not think that was fair?
BTW I have no clue whether any of the above applies in this case. I'm just saying we're guilty of jumping on a bandwagon of thinking Mrs C is a useless golddigger when we really don't know if that's true.
The moral basis for giving her £48m? That's easy. That was the original contract. "All my worldly goods..."
