For an uncontested divorce, legal fees will typically be less than £500 plus VAT and the court fees. Fees are usually shared by the parties.
In a contested divorce, at each hearing the court may make an order regarding the costs of the applications that the court has just dealt with. Usually, the party who lost will be ordered to pay the winning party’s costs. The problem for the judge is often how to assess who ‘lost’ and who ‘won’, particularly at a final hearing.
