The 'special contribution' argument has been very prominent recently....

By this we mean that if considerable wealth has been accumulated within the marriage and this was because of one of the parties success in their career, there could be an argument that the other spouse, who has not contributed as much financially, should not be entitled to half of the assets. 

However, the case of Work and Gray  was recently in the Court of Appeal in which the husband was appealing a financial order which had been made, by stating that because of his financial contribution to the marriage, he should receive a larger share of the matrimonial assets. The Court of Appeal dismissed this and rejected his claim that his "genius outshone her contribution to the marriage".

This therefore shows a significant lean towards equality in the majority of high net worth cases as there cannot be a price put on the importance of raising a family and providing a home... 

We shall see if there are any further cases which accept the special contribution argument- watch this space...
