Lawyers in the United States are recommended under American Bar Association (ABA) ethical rules to contribute at least 50 hours of pro bono service per year. Some state bar associations, however, may recommend fewer hours. Rule 6.1 of the New York Rules of Professional Conduct strongly encourages lawyers to aspire to provide at least 50 hours of pro bono service each year and quantifies the minimal financial contributions that lawyers should aspire to make to organizations providing legal services to the poor and underserved. In contrast, other states, such as Illinois, do not have recommended hours, yet require annual disclosure of voluntary pro bono hours and contributions made to pro bono organizations.
