Given the complicated situation for subrogation that you are in, but apparently are not being sued, I see no reason why you need to have a lawyer representing you for the upcoming depositions that you write about.Yoiu can be deposed in your current state about the lawsuit you are writng about. If you have been served with a subpoena for your deposition, you must obey the subpoena or be subject to an order to show cause regarding contempt.The subrogation claim between the two insurance companies deals with a dispute between the two of them as to which one owes the other moneys expended regarding a prior lawsuit or claim that were paid out.
