A guide to writing a constitution for an unincorporated organisation Every voluntary and community group should have an up to date, adopted constitution – sometimes referred to as the governing document. Remember that there are different models for charities, companies and other forms of organisations listed at the front of this booklet. Only use this guide for unincorporated non-charitable associations. An unincorporated association might be called a group, club, society, organisation, project, social enterprise, self-help group, centre, federation, or just the name of the group.
