We used mediation although I had a solicitor at the end just to push things through. It was excellent but financially there has to be absolute trust and complete transparency, no-one squirrelling any money away or not fully disclosing. Once the Court Order has been agreed that’s basically it (unless you want more hassle).
But it meant for a much much cheaper divorce, no acrimony or lasting animosity. We had no lawyers up against each other, and hurray, no big lawyers’ bills. I really would recommend it.
