My preference is that both parties attend if they are able. First, this reduces cost to you as it reduces the amount of time overall for the mediation process. Second, by communicating directly and through my facilitation, we will avoid misunderstandings and miscommunications. Both of you will be in the Zoom meeting, hearing what the other person has to say. If joint meetings are not possible, we will still make the mediation process work. This is your process. I will tailor it to your needs.
