IOLA stands for interest on lawyers' accounts - it is funded by a fee on attorneys assessed biannually, and those fees are used to compensate clients whose attorneys have cheated them. I can't begin to imagine how you can believe that IOLA information is relevant to a non-disciplinary proceeding. Information pertaining to an attorney's IOLA account is not subject to a subpoena other than issued by the disciplinary authorities.
I am an attorney admitted solely in NY. None of the answers I submit on this forum constitutes legal advice, even to questioners in NY, and no attorney-client relationship is hereby created.
