The simple answer to this is that the charity will have a governing document that it submitted to the Charity Commission in order to obtain registered charity status. This document will contain the rules for operating the charity. Check that the document listed on the Charity Commission website is the same as the one you are currently using, as some charities have amended or replaced their governing document without seeking the approval of the Charity Commission. The document on the Charity Commission website is the one you must use, but you can go through a process with the Charity Commission to change it if you need to. If you would like further advice and support, contact your local ACRE branch, who are the experts in charitable community buildings.
