Jermaine Jackson has branded claims that he has orchestrated the "sudden disappearance" of their mother Katherine as part of a cynical bid to take over the Michael Jackson vast estate as 'lies' and 'nonsense'. Jermaine hit out at the allegations made in court papers filed in Los Angeles last week by his nephew Trent Lamar Jackson. In a statement, released exclusively to DailyMail.com, Jermaine says Katherine's faculties 'remain sharp' and that she is fully aware of everything:

"I would like to make clear that my only priority right now is the health and welfare of my mother. The suggestion that I am somehow orchestrating all this, against her true wishes, is nonsense. Together with my siblings, I support my mother wholeheartedly and stand behind her during this difficult time. This is our mother. We’re looking out for her best interests.  The notion that she can’t act on her own, or can be led astray by me, tells its own story about how Trent Jackson regards her. She is a strong lady but has genuine health concerns about returning home until this matter is resolved. As for the idea that I have plotted Trent’s removal to somehow take control of Michael’s estate, that both overstates his position and underestimates the control that executors John Branca and John McClain currently have. Anyone with any knowledge of how the estate works knows how laughable that claim is. As Michael always taught us, lies run sprints but the truth runs marathons - and the truth of this situation will ultimately be examined in the courts. I would only add that if Trent truly had my mother’s interests at heart, he would know to do the decent thing and walk away."

The papers filed by Trent, were in response to a temporary restraining order granted against him last month by family matriarch Katherine. When the 86-year-old requested the order in February, she wrote in a declaration: 'I believe he has put cameras and bugs in my home, so the only place I can try and have a private conversation is in my bathroom. I used to be very social with my friends, like playing Scrabble, walking around in the park, sharing meals, but Trent has given them various reasons why I am not available," she added. She also claimed she believes Trent has copied the key to her bedroom door, and she gets dressed in her closet out of fear he will walk in on her unexpectedly.

But Trent, and his lawyer, Ron Rale, cast serious doubt over the validity of Katherine's declaration - and went as far as to suggest that she did not write it, but Jermaine did. The nephew's court documents include a copy of Katherine's written statement, however it is edited to show all the parts of it that are being disputed. The documents also claims Jermaine and some of Michael's other siblings are the ones who have treated Katherine poorly, alleging that on occasions they took away her iPad and cell phone and told her the TV was broken. Trent Jackson has been assisting Katherine since Michael's death in 2009.

Katherine's suit said she was unable to appear in court, as she was currently living in London 'under doctor's care'. However, Katherine made her return to Los Angeles last week. Trent's claim requests a judge demand the 86-year-old appear in court, as he believes it would prove she did not write her declaration and she would instead support him. Trent and his lawyer believe the family drama is all the result of attempts to gain control of its lucrative estate.
