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.

In Tennessee, pro bono legal services are an important aspect of the legal community's commitment to ensuring access to justice for all, particularly for those who cannot afford legal representation. Attorneys in Tennessee often volunteer their time and expertise to provide free legal services to individuals who qualify as indigent, meaning they have a low income and cannot pay for legal assistance. These services are frequently coordinated through the state bar association or local legal aid organizations. The Tennessee Supreme Court has an Access to Justice Commission that works to improve the availability of pro bono services across the state. Additionally, legal aid services in Tennessee are typically offered by nonprofit organizations, where attorneys are employed and receive a salary, albeit modest, to serve clients who are eligible based on their income levels. These legal aid attorneys provide assistance at no cost or for a reduced fee, ensuring that legal support is more accessible to those in financial need.
