Going through the court procedure for financial remedy involves making no use at all of the hard work carried out in the mediation process. As part of that, the parties will have given adequate financial disclosure and discussed and narrowed the issues. The exact nature of what they disagree on will be known, as will be their respective positions. All that is actually needed is a decision. In relatively few cases is there any real need for exchange of forms E, statements of issues, questionnaires and so forth. There is no need at all for further delay and expense.
Armed with the material they have produced for the mediator, the parties could easily appoint an arbitrator to take the decision they have been unable to take for themselves.
