July 20, 2012 — -- Michael Jackson fans are up in arms over a letter circulating on the Internet that appears to be signed by several Jackson siblings, including Janet and Jermaine, threatening legal action against the executors of his estate.
In the letter, obtained by ABC News, five Jackson siblings accuse executors John McClain and John Blanca of fraud and abuse of their mother, Katherine Jackson.
"THIS HAS TO STOP NOW; NO MORE!!" the letter reads. "Before we hit the stage, we were a family and still to this day we are a family. We're not going to let anyone abuse our mother, nor will we tolerate any further attempts to divide us."
Thursday, Jermaine Jackson hinted on Twitter that there is more to come: "Re our letter to Estate: while fans only have limited info right now, we ask for patience because much is yet to emerge in this jigsaw..."
The letter, signed additionally by Rebbie, Tito and Randy Jackson, suggested that Katherine Jackson recently suffered a "mini-stroke" as a result of the longtime dispute between the executors and members of the family.
Her attorney disputed that Jackson was in poor health.
"Katherine Jackson is absolutely capable of taking care of the children and does a terrific job," her attorney, Perry Sanders, said in a statement to ABC News. "I have no reason to think that has changed in any way, shape or form. She does a phenomenal job, is extremely lucid and not having any difficulties of any consequence. It's unfortunate that anyone would paint Mrs. Jackson as anything but completely lucid and doing a great job with the children."
Even Jackson's daughter, Paris, 14, has chimed into the dispute.
"i am going to clarify right now that what has been said about my grandmother is a rumor and nothing has happened, she is completely fine," Paris tweeted Wednesday.
"The truth is that Mother DID suffer a mini-stroke some months ago," Jermaine Jackson tweeted Thursday. "She is fine now, but the timeline doesn't alter the fact it happened"
The relationship between the Jackson family and the singer's executors has been strained for most of the three years since Jackson's sudden death from an overdose of the anesthetic Propofol. Many of the allegations contained in the letter have been made by family members before. But the letter threatens new legal action against Branca, an entertainment lawyer, and McClain, a music executive -- both of whom worked with Jackson at different points in his career.
In response to the letter, estate spokesman Jim Bates said in a statement to ABC News, "We are saddened that false and defamatory accusations grounded in stale Internet conspiracy theories are now being made by certain members of Michael's family whom he chose to leave out of his will. We are especially disheartened that they come at a time when remarkable progress has been made to secure the financial future of his children by turning around the estate's finances as well as during a time when so many of Michael's fans, old and new, are enjoying his artistry through exciting new projects."
Bates also dismissed any claims that the will, which was validated in probate court in the months after Jackson's death on June 25, 2009, was somehow a fake.
"Any doubts about the validity of Michael's will and his selection of executors were thoroughly and completely debunked two years ago when a challenge was rejected by the Los Angeles County Superior Court, the California Court of Appeals and, finally, the California Supreme Court," Bates said in his statement.
"Under the supervision of Los Angeles County Superior Court Judge Mitchell Beckloff, co-executors John Branca and John McClain have diligently carried out their fiduciary duties as well as their obligation to Michael to make sure that his estate benefits the only family members he named in his will -- his mother and his three children."
In the letter, the five siblings vow to continue their fight against the executors.
"We are going to take every appropriate action to seek justice and to see to it that the truth be known," the letter reads. "We will hand this over to the proper authorities."
The letter was not signed by Jackie, Marlon and La Toya Jackson, nor did parents Joe and Katherine Jackson sign it.
ABC News requested comments from several Jackson siblings but none of their reps responded immediately.
Here are the top five accusations made in the letter:
The Will Is a Fake:
"The shock of Michael's sudden unexpected passing was overwhelming to our family, to say the least. At that time we couldn't possibly fathom what is so obvious to us now: that the Will, without question, it's Fake, Flawed and Fraudulent.
"Amongst many other inconsistencies in the Will, there is also a conflict around Michael's location on the day he supposedly signed the Will, July 7, 2002. According to what is witnessed in the document, it is impossible and illogical that he could have been in two places at one time. We have evidence that undoubtedly supports and proves that Michael was absolutely not in Los Angeles, California, on the date of his signature reflected in the Will at-hand."
Michael Jackson Despised His Executors:
"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. We know that and you knew that. We believe you relied on the presumption that no one would be so bold as to suggest that you would perpetrate such unconscionable deceit; but you were wrong."
The Executors Are Pressuring Katherine Jackson:
"She is an eighty-two year old woman. Your actions are affecting her health, and on top of that, we've just found out she recently had a mini-stroke. Please understand, she's not equipped to handle the stress load you are putting on her. She feels, as she has said, 'I'm stuck in the middle.' She too knows and acknowledges the Will was forged. She wants to do the right thing, and move in the direction of justice for her son and family, yet she fears the POWERS THAT BE."
The Executors Are Conspiring with Katherine Jackson's Advisers:
"For some strange reason her advisors Lowell Henry, Perry Sanders and Trent [Jackson], although in agreement with her regarding the validity of the Will, are telling her to disregard what she knows as fact. lnstead, her so called advisors are convincing her to let them negotiate 'deals' with Branca and McClain on her behalf, or is it on the behalf of all of you. Her advisors' loyalty seems to be skewed by the percentage you offer them, preventing them from advising her properly."
Sanders responded to CNN that "my only loyalty in this matter is to Mrs. Jackson, and the public record of my success for her speaks for itself."
The Executors Are Part of a Conspiracy Surrounding Jackson's Death:
"We know there is most certainly a conspiracy surrounding our brother's death and now coarse manipulation and fear are being used to cover it up. Your heartless pursuit of wealth, fame and power is at the expense of our family, whose deepest desire is to give to the world a gift of hope, love and unity through our music. Though we have lost our brother, we live and will continue to fight in unity."
