This document provides an overview of different legal structures for social enterprises, dividing them into unincorporated and incorporated groups. Unincorporated structures include associations, trusts, and partnerships, while incorporated structures comprise companies, industrial and provident societies, community interest companies, and charitable incorporated organizations. The main distinction is that unincorporated organizations do not have a separate legal identity, so individuals involved may be personally liable for debts and liabilities, while incorporated structures are legally distinct entities.
