“The matter stands differently regarding property (‘non-matrimonial property’) the parties bring with them into the marriage or acquire by inheritance or gift during the marriage …”
“The nature and the source of the property and the way the couple have run their lives may be taken into account in deciding how it should be shared.”
“… In order to consider the exercise of assuming purely passive economic growth would … require an economist to identify statistically significant correlations that have a causal impact on the company …”
“… not, however, an economist and [does] not have relevant expertise … Therefore, there is significant difficulty for a non-economist such as [himself] to apply the concept of passive growth.”
“On the other hand, where at the beginning (or end) of the marriage an actual transaction is under way or in view which in due course yields a considerable new asset, there is no difficulty in principle (even if there may be some difficulty in valuation) in accepting that part of that asset may have to be excluded from any assessment of matrimonial acquest or included in what the parties brought into the marriage. In the present case, Mr Miller already had, at the marriage date, real connections in the form of the Jupiter funds which he later took to New Star and real prospects under the gentlemen’s agreement made with Mr Duffield of acquiring, as he subsequently did, valuable shares in New Star. I would regard these as real contributions brought into the marriage, which should on any view be taken into account accordingly.”
“Thus a special contribution arises in circumstances in which a spouse’s contribution, direct or indirect, to the creation of the matrimonial property has been so extraordinary as to dictate a departure within the sharing principle from the ordinary consequence of its equal division …”
“Criticism can easily be levelled at both approaches. In different ways they are both highly arbitrary. Application of the sharing principle is inherently arbitrary; such is, I suggest, a fact we should accept and by which we should cease to be disconcerted.”
