(a) The mediator in writing shall:
(1) Inform the parties of the costs of mediation;
(2) Advise the parties that the mediator does not represent either or both of the parties;
(3) Define and describe the process of mediation to the parties;
(4) Disclose the nature and extent of any relationships with the parties and any personal, financial, or other interests that could result in a bias or a conflict of interest;
(5) Advise each of the parties to obtain independent legal advice;
(6) Disclose to the parties’ attorneys any factual documentation revealed during the mediation if at the end of the mediation process the disclosure is agreed to by the parties;
(7) Ensure that the parties consider fully the best interests of the children and that the parties understand the consequences of any decision they reach concerning the children.
(b) The mediator may meet with the children of any party and, with the consent of the parties, may meet with other persons.
(c) The mediator shall make a written summary of any understanding reached by the parties. A copy of the summary shall be provided to the parties and their attorneys, if any. The mediator shall advise each party in writing to obtain legal assistance in drafting any agreement or for reviewing any agreement drafted by the other party. Any understanding reached by the parties as a result of mediation shall not be binding upon the parties until it is reduced to writing, signed by the parties and their attorneys, if any, and approved by the court. If any party is not represented, the mediator shall provide to the court the written summary of any understanding reached by the parties.
(d) The mediator may act as a mediator in subsequent disputes between the parties. However, the mediator shall decline to act as attorney, counselor or psychotherapist for either party during or after the mediation or divorce proceedings unless the subsequent representation, counseling, or treatment is clearly distinct from the mediation issues. The mediator may not subsequently act as an investigator for any court- ordered report nor make any recommendations to the court regarding the child care issues.

Plain-English Summary

Rule 88.06 spells out what a mediator must do once mediation is underway, and much of it must happen in writing. The mediator must inform the parties of mediation’s costs, make clear that the mediator does not represent either party, and describe how the mediation process will work. The mediator must also disclose any relationship or interest — personal, financial, or otherwise — that could create bias or a conflict of interest, and advise each party to get independent legal advice.

The rule also addresses disclosure of information uncovered during mediation. Factual documentation revealed in the process can be disclosed to the parties’ attorneys only if, at the end of mediation, both parties agree to that disclosure. And throughout, the mediator must make sure the parties fully consider their children’s best interests and understand the consequences of any decisions affecting the children.

Beyond these written duties, the mediator may meet with the parties’ children, and with the parties’ consent, may meet with other people relevant to the case. If the parties reach an understanding, the mediator must summarize it in writing and provide that summary to the parties and their attorneys. That understanding does not bind the parties until it is put in writing, signed by the parties and any attorneys, and approved by the court. If a party has no attorney, the mediator must send the written summary directly to the court.

The rule also limits the mediator’s subsequent roles. A mediator may mediate later disputes between the same parties, but must decline to act as their attorney, counselor, or psychotherapist during or after the mediation or divorce proceedings, unless any later representation, counseling, or treatment is clearly separate from the mediation issues. And a mediator can never later serve as an investigator on a court-ordered report or make recommendations to the court about the children.
