Pro bono

From Wikicpa

Pro bono is a phrase derived from Latin meaning "for the good". The complete phrase is pro bono publico, "for the public good". It is used to designate legal or other professional work undertaken voluntarily and without payment, as a public service.

In some cases pro bono counsel may assist an individual or group on a legal case, in filing government applications or petitions or on appeal. Lawyers are recommended under ethical rules to contribute at least fifty hours of pro bono service per year.
