The Indiana State Bar Association (ISBA) is a voluntary bar association for the state of Indiana. Unlike some state bar associations, in which membership is mandatory, ISBA membership is not required of lawyers licensed to practice in Indiana. The ISBA is headquartered in Indianapolis, Indiana. It includes among its members lawyers, judges, paralegals, law librarians, law students, and court administrators. About 85% of the practicing lawyers in the state are members.
