Pro bono legal services are services that are provided to a person or entity without requirement or expectation of payment to the attorney for the services. These volunteer legal services are provided by lawyers—often through state bar associations—and are usually available only to persons who are unable to pay for the services, and qualify as indigent based on their income. In contrast, legal aid services are often provided at no cost or reduced cost by attorneys who work for nonprofit entities, and the attorneys are paid a modest salary by the nonprofit entity.
