The mediator is obliged to confidentiality about all facts that he gets to know during the mediation or in any other way. He has to handle all documents that are created or submitted during the mediation, with confidence. The same applies to the mediator’s assistants as well as to people who work in a practical training with a mediator under his/her guidance (§ 18 Mediation Law 2003). This means that, depending on the legal form of this duty, mediators especially will not become a witness in court. Thus, mediation is basically a non-public method to protect the privacy of mediands.
