Unless authorized by a charitable organization, a person may not: represent that a charitable contribution is requested for the charitable organization; or use a name, symbol, emblem, device, service mark or printed matter that belongs to or is associated with the charitable organization to solicit charitable contributions. In soliciting charitable contributions for a charitable organization, a person may not use a name, symbol, emblem, device, service mark, or printed matter so similar to that of another established charitable organization that the use might confuse or mislead the public.
