 Some organizations such as a transit district or special purpose corporations such as a university, are also created by statute.In some states, a city or county can be created by petition of a certain number or percentage of voters or landholders of the affected area, which then causes a municipal corporation to be chartered as a result of compliance with the appropriate law.Corporations to be established for most other purposes are usually just incorporated as any other non-profit corporation, by filing the paperwork with the appropriate agency as part of the formation of the entity.
