I have finished family law mediation with my ex without much success. Since mediation, she is now after more money then what was agreed upon at mediation. We agreed on a 55/45 split and now she wants 57.5%. I have had to file court orders as well as she has also changed superannuation dates and amounts. Her solicitor has told me that I can't use the evidence from mediation in court. How do I use this information to prove that they are being greedy and not sticking to the agreement at mediation? There was no paperwork signed at mediation but I do have an email confirming what was verbally agreed upon at mediation.
