Well it's not necessarily good news, but typically, it probably is, given that your friend's husband earns twice more than her. The court will decide based on the individual facts and circumstances of this case within the context of family law legislation and case law.
If your friend is a housewife who sacrificed her career to run the family home and raise the children whilst her husband built a career with a high salary and excellent future prospects, she should do well in any divorce settlement - because her 'resources' are far more limited than the husbands. It is easier for the husband to start again, but less so for your friend perhaps, who may also continue supporting the children and require a larger home.
The aim for equal share of the matrimonial property only applies when the parties resources are equal. But typically, this is not so. Typically, the separating husband has more resources than the wife, hence an unequal distribution of assets is fair.
