New reports suggest that Michael Jackson‘s family is split over the authenticity of his will.

This week, several of his siblings, including Janet, Rebbie, Tito, Jermaine, and Randy, sent and signed a letter to Michael’s estate, claiming that the will the late singer supposedly left behind was forged.

The siblings who signed believe that the estate’s executors, John Branca and John McClain, forged Michael’s signature on the document and that the continuous dispute between Branca, McClain, and the Jackson’s caused Katherine Jackson to suffer a “mini-stroke” months ago.

According to CNN, the Jackson family members who sent the letter bring up previous and new allegations agains Michael’s estate.

The letter mostly repeats allegations made by family members, but it also threatens new legal action against Branca, an entertainment lawyer, and McClain, a music executive, who worked with Jackson at several points in his career.

“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,” they wrote. “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.”

When the letter was released earlier this week, it garnered a response from Michael’s daughter Paris Jackson, in which she took to Twitter denying that her grandmother had a stroke and saying that her uncle Randy was lying about Katherine’s health. She tweeted:

“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 later deleted the tweet and instead sent out an apology to Randy.

“I am sorry for my quick reaction this morning. It was my foolish retaliation that i do regret. My tweet was merely about the remark about the stroke. She did NOT have a stroke today. I sincerely apologize from the bottom of my heart.”

Katherine’s lawyer Perry Sanders has also denied reports that she is in poor health.

“Katherine Jackson is absolutely capable of taking care of the children and does a terrific job. It’s unfortunate that anyone would paint Mrs. Jackson as anything but completely lucid and doing a great job with the children.”

Either way, the Jackson siblings say they have evidence that Michael was not in Los Angeles on the day that the will was signed and that the estate’s executors have dishonored everything their brother stood for.

Hopefully, the family can find some way to work this all out.
