and he should have had her sign a pre- nuptial agreement.
It wouldn't matter if he had, pre-nuptials are somewhat incompatible with English law and as such cannot be relied upon in an English Court.
The Matrimonial Causes Act 1973 means that nothing you put in a contract can override the court’s discretion to vary the provisions in a pre-nuptial agreement. This can mean that a pre-nuptial agreement is unenforceable as the Court has the ultimate power to decide what is fair in divorce proceedings. In particular, a pre-nup goes against the idea that marriage is for life as it contemplates divorce.
So while pre-nups are a good idea in theory, in England and Wales (I'm not sure of the Scottish or Northern Irish law on this) in practice they are worth little more than the paper they are written on.
I hear for their first married Christmas he bought her a plane. For her other leg he bought a razor.
