Divorce mediators do not have the authority of a judge behind them, and therefore lack any power to make binding demands on either party. Thus, the success of mediation depends entirely on the cooperation of the parties. Similarly, the mediator has no way to compel either party to do anything, such as reveal income or assets, within a reasonable period of time.
Second, one spouse sometimes perceives the mediator as favoring the other, and when this happens, the likelihood of reaching an agreement with the mediator diminishes.
Third, a mediator may not advise you fully of the law, and the possibility exists that you will reach an agreement unaware of rights you have lost.
Next, a mediated agreement should still be reviewed by a lawyer for each side or the lawyers should participate.
Finally, there is no mediator/client privilege. That means that what you disclose to the mediator is not confidential. However, the Mediator cannot be subpoenaed to testify and none of the dialogue/offers or legal positions discussed in mediation can be divulged or admitted in subsequent litigation.
