A memorabilia dealer is fighting the legality of the will of the late Michael Jackson, stating that he has clear and compelling evidence that the document is a fake.  Howard Mann, who wrote a book with Katherine Jackson, Michael’s mother, says that he is “in possession of evidence that casts substantial doubt on the validity of the will.”

Mann told the New York Daily News that he would like to present the information in court to help in the case that is set to go to trial next month.  Mann is in a battle with the executors of the estate over the intellectual property in the book and website that he created in order to sell it.

“I am not backing down from my court fight with these guys. I’m not interested in settling with them. I came out and said these guys were a fraud two years ago,” Mann said.

“I have many people who will come and give testimony that the entire administration is a fraud and a collusive operation designed to take assets away from Katherine and Michael’s kids,” he said.

Mann says that his evidence is, in part, related to the fact that Michael is alleged by the executors to have signed his will in 2002 when he was in New York at an event hosted by Rev. Al Sharpton.

The executors have referred to the allegations as “false and defamatory.”

Mann said that he would like to have experts review the validity of the writing on the will and make sure that it’s all legitimate.
