A trained mediator may or may not also be a lawyer. While it is not necessary that the mediator you hire is also a lawyer, there are considerable advantages if your mediator is an attorney. For example, even though mediation allows you and your spouse to avoid going to court, divorce is a legal process, and your case will ultimately go before a judge. If your mediator is a lawyer, they will have a better understanding of the court system and what is required in order for a divorce agreement to be deemed acceptable.
