The minor' counsel appointed by the court appears not to like me. Can I have them removed?

There is a very limited circumstances for which the Court can remove minor's counsel from a case. Keep in mind that the Court may have had significant input or appointed the particular minor's counsel that you are having issues with. To criticize the attorney is in essence criticizing the judge. A better approach is to argue your point to the court rather than get into a heated argument with minor's counsel. Another alternative is to hire an attorney who may know the minor's counsel (or be readily familiar with them) that may be able to shed light on how best to interact with the particular minor's counsel. If communication brakes down with minor's counsel, it may be time to remove yourself from the situation.
