There have been many complaints about long delays in releasing fees to attorneys who represent Social Security claimants. These fees are withheld from the back benefits of the claimants involved. The Social Security Administration receives a user fee for their costs in withholding and paying these fees. I hear that in a recent telephone call with Social Security management about the problem the National Organization of Social Security Claimant Representatives (NOSSCR) was told that the agency didn't even consider a fee payment to be delayed unless the delay was more than nine months!
If you were deliberately trying to drive attorneys out of the practice of Social Security law, this would be a good way to do it.
