Some Social Security disability claimants do not hire a lawyer because they believe they cannot afford one. However, the SSA-approved contingency fee process means that it does not cost a penny to hire a lawyer, and there is no fee unless a disability or SSI claim is successful. We do not get paid unless you get paid.
I speak with prospective clients regularly, and many do not realize that fees for a Social Security disability lawyer are almost always contingency fees. This also means we talk with you a bit about your claim before we represent you. That way, you have a lawyer that believes in your claim as much as you do.
There is a permanent page on this site About Attorney Fees, which provides further detail. The bottom line is that you should seek help with your disability claim regardless of your current ability to pay for a lawyer.
