Return to Videos Yes, you can hire an attorney to fight a denied claim. The fees are set by federal statue and the fees are either $6,000 presently or 25%, whichever is the lesser. Not the greater, but the lesser. Attorneys who do this, do this on a contingency fee basis. If they don't win, you don't owe them anything. Typically at the time that you win or your check is cut, or electronically issued by the Social Security Administration, the 25% is deducted from your first back check and that goes to pay your attorney. If there are any costs involved, which shouldn't be any more than a few hundred dollars for obtaining medicals records and medical opinions in some cases, then that's between the attorney and the claimant. But there should be no reason or impediment to somebody actually going out and finding a good attorney and hiring them for their claim.
