It includes extensive coverage of unincorporated business associations with particular emphasis on the general partnership, limited partnership, and limited liability company. This edition also features extensive coverage of changes made by the Restatement of Agency, 3rd, the Revised Uniform Partnership Act, and the Delaware Limited Liability Company Act.
