Sometimes mediators work on their own, sometimes in pairs, which is called co-mediation.
The cost of mediation is usually paid for at the beginning of each session. Payments can be made by card or cheque.
At the end of the process, you can request a Memorandum of Understanding which details the proposals you have made together. You can share them with your solicitors so they can easily and quickly be turned into the documents that are required to make your proposals legally binding.
