“Fairness 75 White v White[2001] 1 AC 596 and McFarlane v McFarlane[2006] 2 AC 618 establish that the overriding criterion to be applied in ancillary relief proceedings is that of fairness and identify the three strands of need, compensation and sharing that are relevant to the question of what is fair. If an ante-nuptial agreement deals with those matters in a way that the court might adopt absent such an agreement, there is no problem about giving effect to the agreement. The problem arises where the agreement makes provisions that conflict with what the court would otherwise consider to be the requirements of fairness. The fact of the agreement is capable of altering what is fair. It is an important factor to be weighed in the balance. We would advance the following proposition, to be applied in the case of both ante- and post-nuptial agreements, in preference to that suggested by the Board in MacLeod v MacLeod[2010] 1 AC 298 : “The court should give effect to a nuptial agreement that is freely entered into by each party with a full appreciation of its implications unless in the circumstances prevailing it would not be fair to hold the parties to their agreement.”
“if the parties to a prospective marriage have something important to agree with one another, then it is often much better, and more honest, for that agreement to be made at the outset, before the marriage, rather than left to become a source of disappointment or acrimony within marriage.”
“... I have in mind (and in this respect there is no real difference between an agreement made just before or just after a marriage) that a pre-nuptial agreement is intended to look forward over the whole period of a marriage to the possibility of its ultimate failure and divorce: and thus it is potentially a longer lasting agreement than almost any other (apart from a lease, and those are becoming shorter and subject to optional break clauses). Over the potential many decades of a marriage it is impossible to cater for the myriad different circumstances which may await its parties. Thorpe LJ has mentioned the very relevant case of a second marriage between mature adults perhaps each with children of their own by their first marriages. However, equally or more typical will be the marriage of young persons, perhaps not yet adults, for whom the future is an entirely open book. If in such a case a pre-nuptial agreement should provide for no recovery by each spouse from the other in the event of divorce, and the marriage should see the formation of a fortune which each spouse had played an equal role in their different ways in creating, but the fortune was in the hands for the most part of one spouse rather than the other, would it be right to give the same weight to their early agreement as in another perhaps very different example?”
