Social Security disability attorneys work on a contingency fee basis. That means they only charge a fee if they win your case. SSA limits how much an attorney can charge and must approve the fee. SSA currently allows an attorney to charge up to 25% of the applicant’s past-due benefit up to a maximum of $6,000. SSA withholds the attorney’s fee from the applicant’s award and pays the attorney directly. The fee is on the past-due benefit only. There is no fee on the ongoing monthly benefit.
