Typically, in Massachusetts, if the party that holds the order wants to have it dismissed, they would make a motion in the court to do so.  That party would be required to give you notice, so that you can oppose any potential change in the restraining order.  While it is not mandatory for you to be present for your wife to proceed, I would strongly recommend that you attend the hearing, if only to make sure that the order is not changed in some other way.  You can sit on an opposite end of the court from her, and simply give your assent when the judge asks if you object to the order being dismissed.  In the event the judge makes some other change, you will know what the change is.
