Your charity’s objects or purposes, and the rules for how it should operate are set out in its Governing Document.

Only change your governing document if it’s in your charity’s best interest to do so. For example, if:

• your charity’s purposes aren’t a practical or appropriate way to meet the need it was set up for any more
• your governing document doesn’t say who your charity’s trustees are or how they are appointed
• provisions explaining how you must run the charity (for example, how to arrange meetings) are no longer relevant or practical

As trustees, you’ll need to decide that the change is necessary and what it should be. You can make some changes yourself but others need Charity Commission permission.
