KARACHI: Janet Jackson and four of her siblings sent a scathing letter to the men who control Michael Jackson's estate, accusing them of fraud and of abusing their mother.

The letter states: “At the time we couldn't possibly fathom what is so obvious to us now: that the Will, without question, it's Fake, Flawed and Fraudulent. Since the passing of Michael, our beloved brother, you have failed to perform your duties as executors of his estate, but what you have not failed at is taking advantage of a grieving mother, father and a grieving family. Our brother told us, in no uncertain terms and without hesitation in the months prior to his death, that he despised both of you and that he did not want either of you to have anything to do with his life or estate for that matter. The Will that you presented did not have our brother's signature on it, nor did it have a signature page attached to it.”

The letter also noted amongst many other inconsistencies in the Will, there is also a conflict around Michael's location on the day Jackson supposedly signed the Will, July 7, 2002. Jackson siblings claim that they have evidence that undoubtedly supports and proves that Jackson was not in Los Angeles, California, on the date of his signature in the Will.

Finally, the five Jacksons wrote that they would "take every appropriate action to seek justice and to see to it that the truth be known."

"Be informed, we are considering retaining a law firm, Baker Hostetler, who have advised us on the potential criminal misconduct in your actions. We will hand this over to proper authorities," they wrote.

The validity of Jackson’s will was challenged in court two years ago and the assertions that it was a fake were dismissed.
