In some cases a health and disability attorney will not charge the type of retainer or fee that other attorneys may charge, but rather may be funded through community or state based programs. In other cases the attorney may work for a non-profit or charitable agency that funds through grants rather than charging the client.
If you need a health and disability attorney but do not have the funds to hire a private attorney, consider looking into various charitable or non-profit community services that may be available in your area. Often these services will be available through a community programs directory.
