Mediation is a voluntary process and clients are free to stop at any time. It is part of my role to manage the process, ensuring everyone feels able to speak, allows others to be heard and that everybody behaves respectfully. I can end a meeting if it is no longer constructive.
Agreements are not final until everyone has had a chance to seek advice and have agreed to make them legally binding. Therefore no client is obliged to agree to anything that is not in their best interests.
