The Committee for Public Counsel Services is the state agency in Massachusetts responsible for providing an attorney when the state or federal constitution or a state statute requires the appointment of an attorney for a person who cannot afford to retain one. The agency provides representation in criminal, delinquency, youthful offender, child welfare, guardianship, mental health, sexually dangerous person, and sex offender registry cases, as well as in appeals and post-conviction and post-judgment proceedings related to those matters.
