“Thus, with respect to Lady Hale, I believe that the true proposition is that the importance of the source of the assets may diminish over time. Three situations come to mind: (a) Over time matrimonial property of such value has been acquired as to diminish the significance of the initial contribution by one spouse of non-matrimonial property. (b) Over time the non-matrimonial property initially contributed has been mixed with matrimonial property in circumstances in which the contributor may be said to have accepted that it should be treated as matrimonial property or in which, at any rate, the task of identifying its current value is too difficult. (c) The contributor of non-matrimonial property has chosen to invest it in the purchase of a matrimonial home which, although vested in his or her sole name, has-as in most cases one would expect-come over time to be treated by the parties as a central item of matrimonial property. The situations described in (a) and (b) were both present in White v White. By contrast, there is nothing in the facts of the present case which logically justifies a conclusion that, as the long marriage proceeded, there was a diminution in the importance of the source of the parties’ entire wealth, at all times ringfenced by share certificates in the wife’s sole name which to a large extent were just kept safely and left to grow in value.” [52] We agree with those obiter dicta of Wilson LJ. But it is important to note that Wilson LJ’s three situations were plainly not expressed to be exclusive categories. In this case in the Court of Appeal, Moylan LJ said, at para 163, that “the concept of matrimonialisation should be applied narrowly”
