Confidential Side Letters to the Mediator

June 5, 2023

Before the mediation, at the invitation or suggestion of the mediator, a party may elect to send the mediator a confidential side-letter in addition to the pre-mediation statement exchanged with the other party. The side-letter for the mediator’s eyes only is an opportunity to communicate additional private or sensitive information, interests, concerns, or requests to the mediator without disclosing it to other participants. These letters typically inform the mediator about the party’s settlement preferences, financial concerns, personal information, or information about the other party that might impact the mediation but which for one reason or another the party does not want to share with the other party at the time of mediation. Confidential side letters to the mediator are private and are not shared with any other participants of the mediation, unless permission is explicitly granted to do so. The mediator is prohibited from sharing any aspect of the confidential letter with any other participant of the mediation as they are bound by the rules of confidentiality, and a party is not required to submit a confidential letter even if other participants do.

The purposes of the side-letter to the mediator are to provide the mediator with a deeper awareness of a party’s position and concerns, to allow the mediator to better understand the potential hurdles or proposed solutions or settlement offers, and to allow the mediator to understand the parameters of the negotiation and potential alternative solutions or paths to settlement than the opening positions set forth in the pre-mediation statements.

Among other things, the confidential side letter to the mediator may allow a party to:

There are potential downsides to the side-letter to the mediator:

Different mediators have different preferences for confidential letters, so it is advisable to consult with the mediator directly to determine the mediator’s preferences for the format and nature of the statement. In any event, the side letter itself should make clear that it is confidential and for the mediator’s eyes only and is not to be shared with the other party.

As the mediator is a neutral third party between the participants, sharing sensitive and private concerns and interests with the mediator before the mediation begins can highlight the deeper dynamics of the participants and the dispute, helping the mediator in finding a beneficial resolution for both parties. It may also be a useful tool to further advocate for your position in mediation, and ultimately to avoid litigation.
