Something that comes up from time to time is that clients will misinterpret my explanation of arguments that the opposing party may make as disloyalty. Preparation is everything in litigation. Being prepared includes (a) anticipating arguments the other side will make, (b) identifying weaknesses in the client’s case, and (c) trying to think of ways to overcome both.
The client needs to know what the problems with their case are so they are fully informed when they have to make key strategic decisions. Being realistic about problems is essential.
Sometimes clients go so far as to accuse me of working for the other side. That creates a huge problem. If the client and I are adverse, I have a conflict of interest and have to get out of the case.
