Can I deduct legal fees for a group long term disability claim?

I hired a lawyer to appeal my group long term disability claim, with a 30% contingent fee. The claim was approved. I received a W-2 from the insurance co, listing the full recovery as my income, with 45% being taxable income in Box 1 and 55% as non-taxable in Box 12, code j. Can I deduct the 30% or part of the 30% attorney fee?
