Your lawyer can help you to select a mediator or, if in court, a judge can appoint one. Mediators can be lawyers, mental health professionals, clergy, and other trained professionals. You and your spouse should both trust the mediator since this individual is going to help you to communicate through your differences. A divorce law firm may have attorneys trained in mediation but that do not act as certified mediators. You should hire a trained attorney to work with your certified mediator.
