Mediation may be the most efficient manner to resolve your differences. When you hear family and friends discuss "out of court" settlements, this may be one of the many methods that they used to arrive at an agreement. Michelle Sullivan, acting as a mediator, will not act as either party’s attorney of record but as a neutral party to facilitate discussions privately in our office. You and your spouse will be the exclusive decision makers regarding the outcome of any agreement. In arriving at a Mediated Agreement, Michelle Sullivan has found that many times the parties are able to find creative and effective strategies to resolve their differences, which would not be available through the avenues of traditional litigation. This allows the parties to custom-make their settlements to meet their and their family’s needs.
