I am not sure, to be honest. if I did I might reply with something like:

"Oh, you and I know about D1, D2 and my accounts ending with 1234, 2345, 3456. I know of no others."

I'd leave the "I'm sorry that you don't want to work together on this. I guess if you think it's better to give away thousands of dollars that we don't have to lawyers then there is nothing I can do about it. Do you mind telling me who you have as a lawyer and if I am going to be served papers?" alone.

Just my opinion...
