Lawyer deception

I have given all of my investment information to her lawyer. He continues to “forget” funds and now makes claims on a fund that was not in question instead of the one that was in question. He is confusing my wife into thinking I am withholding information, which I have not done. How do I make her lawyer stick to the issues or is this a lawyer trick to get both of us confused?

You certainly can force her lawyer to act a certain way. She has the ability to no longer use that lawyer, or retain another, if she feels the same way. You can always copy your wife on correspondence to her lawyer so that she can see exactly what you are communicating.
