What is the best way to help our client with his legal problems? Will doing a Protocol session on all the parties to this legal matter be effective or does he need deeper healing personally? What can the divine realm do to help?

You are reading this situation well intuitively. The entire group of individuals involved in the dispute need healing—him included. This is because there is a long-term karmic entanglement here from past life experiences that is shaping the event in question and its slow resolution. The way to break the logjam is to remove the karmic imperative creating a conflict and a confrontation, then the practical advantages of resolving this will be seen with greater clarity and less resistance. The karma dictates there must be a winner and a loser, whereas common sense dictates there can be a win-win from creating a lesser of evils outcome, even for the loser, and that is what you can work towards by doing the healing as a group process to reach each of the parties who have a bearing on what takes place within the legal system to adjudicate the matter. We, of course, will be assisting all along the way if you choose to move forward.
