One way around the potential 'Double Taxation' pitfall would be to somehow have the attorney's fees awarded directly to him by the Court as opposed to having it awarded to the Plaintiff who then remits it to the attorney. I would think this could somehow be worked out in the determination of the final form of the judgment but not sure.

They usually are already, in that the lawyer gets the award, and deducts his portion, then issues a check to his client for the remaining amount.
I know a lawyer and this is common practice.
