Can my ex have his sister in our divorce hearing?

Asked by Missindependent (12) October 27th, 2014 from iPhone

She helped him file the petition for divorce as a non lawyer, we do not have lawyers. Can his sister either represent him in court or be in the court hearing? (She is not an attourney) We are going to a general magistrate for our final hearing, I honestly thought it could only be the husband and wife in the room. Please help.
