Notwithstanding any other provision of this article, there exists a fiduciary relationship between a charity or any person soliciting on behalf of a charity, and the person from whom a charitable contribution is being solicited. The acceptance of charitable contributions by a charity or any person soliciting on behalf of a charity establishes a charitable trust and a duty on the part of the charity and the person soliciting on behalf of the charity to use those charitable contributions for the declared charitable purposes for which they are sought. This section

is declarative of existing trust law principles.
