Social Security Attorneys fees are regulated by the Social Security Administration and virtually all attorneys charge the same fees. Many are familiar with the type of fees "contingency fees" charged by accident lawyers. Just like accident lawyers, social security attorney charge only if they win. They usually charge 25% of any back payments you receive from SSA when you win. The fees are limited to $6,000 by the Social Security Administration in most cases. The person applying keeps 100% of any monthly checks received once they start. Expenses in a social security disability or SSI case are usually only $100 or $200 and most attorneys only charge these to the client if they win. In many cases there are no expenses. So you don't need to worry whether you can afford an attorney for your disability or SSI case if you have little money, like most disabled people.
