The UK charity can take a number of different forms. By far, the most common form for new charities today is the CIO. This was introduced a few years ago. Older charities are often in the form of a company limited by guarantee under the Companies Act, or in some cases, even a limited company under the Companies Act. Some even older charities are in the form of an unincorporated trust. A trust used to be very common for charities, but then it was realized that trustees had unlimited liability for the debts of the charity. So, trustees tend to prefer one of the incorporated models. As I said, today it is the CIO which is by far the most common model.
