In 2007, the Ohio state Division of Real Estate and Professional Licensing issued a statement warning people against some of the illegal methods preached by Kiyosaki in his books and seminars.[53][54] In 2010, the Canadian Broadcasting Corporation did an exposé on scams that were being perpetuated by Kiyosaki's company in Canada in the guise of seminars. Upon tracking the success claims of "Rich Dad" seminar organizers, they discovered that these claims were not true. Investments in trailers and trailer parks, which were being propagated as "successful" by seminar teachers, were found to actually be barren pieces of land that no one was using.[55]
From 1990 to 1995, Kiyosaki used Amway to promote his book with multi-level marketing. He was sued by his fellow author Sharon Lechter in 2007 for not keeping to the terms of their agreement.[56]
Kiyosaki's advice have been criticized for emphasizing anecdotes and containing nothing in the way of concrete advice on how readers should proceed or work
