i went to mediation for something different and found it useless. it was about £100 and because we didnt agree we didnt get anything written up. so unless you thinhk you will agree there is little point going imo. the mediator was a pompous old git who told me ds probably developed aspergers because of the relationship between me and xp. he refused to be convinced he was anything other than 100% correct and conducted the rest of the session with this in mind, meaning the real problems were ignored. it also took several months to get an appointment so might not be any quicker than writing to each other. as it wont be legally binding anyway you could always try writing yourself, then at least you have proof of what you did/didnt agree if you end up in court
