Do you think court proceedings are the only option now mediation has broken down? Think again. Think family Arbitration. Ask your solicitor for information. 
Don’t believe that family arbitration is more expensive than court it can actually work out cheaper. It’s confidential, binding and quicker.  Why spend 12-18 months minimum in court if you can avoid it? 
Your solicitor should be talking to you about arbitration as a much better alternative to court. It can also work with mediation if the mediation breaks down because there is something you can’t agree on. 
Even if you are in court proceedings now and are angry and frustrated by delays and the Court’s mismanagement of your case you can choose arbitration. You and your ex can agree to suspend the court process to have the case decided by arbitration. 
Arbitration works.
