Several states have modeled their state laws after the Model Nonprofit Corporation Act, which was approved by the Business Law Section of the American Bar Association in 1964 and revised in 1987. Other states have not explicitly adopted either version of the model act but may borrow provisions from the model legislation. Another source of law governing nonprofit entities appears in the form of the Uniform Unincorporated Nonprofit Association Act, which was approved by the National Conference of Commissioners on Uniform State Laws in 1996. Eleven states have adopted this uniform law, which serves as a complement to the model act.
