Plaintiff appeals as of right from a judgment entered on a settlement agreement reached during mediation pursuant to the Community Dispute Resolution Act, MCL 691.1551 et seq.; MSA 27.15(51) et seq. We affirm.

Plaintiff argues that the settlement agreement was void ab initio because there was no enforceable underlying agreement between the parties to submit to community dispute resolution mediation, there being no agreement made on the record in open court or evidence of the agreement in writing subscribed by plaintiff as required by MCR 2.507(H). We disagree because this court rule is inapplicable to this community dispute resolution mediation.* 1 The Community *56 Dispute Resolution Act sets up a procedure apart from court actions; participants in mediation may or may not be litigants in a pending lawsuit. The act requires only that “[p]articipation in the dispute resolution process shall be voluntary,” MCL 691.1556(1); MSA 27.15(56)(1), and the trial court here found, without dispute from plaintiff, that the parties did, in fact, participate voluntarily. As a result of his voluntary participation, plaintiff is subject to the provisions of the act, notwithstanding the fact that his voluntary participation resulted from a referral to the dispute resolution process by the trial court in a pending case.

As a result of the mediation, the parties entered into and signed a written agreement. The act specifies that this agreement “is enforceable in the same manner as any other written contract.” MCL 691.1556a; MSA 27.15(56a). Under usual contract principles, plaintiff is bound by the settlement agreement absent a showing of mistake, fraud, or unconscionable advantage. Prichard v Sharp, 51 Mich 432, 435; 16 NW 798 (1883); Marvin v Marvin, 203 Mich App 154, 157; 511 NW2d 708 (1993); Meyer v Rosenbaum, 71 Mich App 388, 393-394; 248 NW2d 558 (1976). Plaintiff does not advance any claim on appeal that the settlement agreement was the result of mistake, fraud, or unconscionable advantage. Instead, plaintiff seeks to upset the validity of the settlement agreement on the ground that the mediation did not comply with MCR 2.403, a rule that is inapplicable to this community *57 dispute resolution mediation. Additionally, plaintiff asserts that the settlement agreement should be upset because, in hindsight, plaintiff made a mistake or was ill-advised in his decision to forgo the presence of counsel and his son Arnold Plamondon at the mediation. Absent a showing of mistake, fraud, or unconscionable advantage, plaintiff has failed to demonstrate grounds to set aside the settlement agreement.

We affirm.
