The petition also stated that the children have "no relationship with their biological mother." And that it is "not known" whether the mother agrees that Katherine Jackson should be guardian. As for the mother of Prince Michael II, known as Blanket, a box is checked for "none."
Asked about Rowe, Joe Jackson said, "Debbie Rowe has nothing to do with what we're doing."
Rwaramba, 42, worked for Jackson for nearly two decades, starting as an office assistant who handled insurance for his employees.
Over time, observers said Rwaramba had taken an increasingly central role in the lives of Jackson and his children. Jackson and Rwaramba were even rumored to be considering marriage in 2006
Joe Jackson said Rwaramba, who Michael Jackson fired in December, was still "a good friend of the family and the kids." He said the family is looking into what role she can have in the kids' lives.
Beckloff's ruling also named Katherine Jackson special administrator of Jackson's property, pending a hearing July 6.
The judge's ruling did not cover Jackson's financial assets, which includes his stake in the Sony-ATV Music publishing catalog. The catalog contains legendary music from the Beatles and Bob Dylan, as well as new acts such as the Jonas Brothers. Its worth has been estimated at as much as $2 billion.
A hearing to consider those requests has been scheduled for Monday.
A source confirmed that Jackson drafted a will in 2002 and the document will filed in court as early as today. Longtime Jackson attorney John Branca and John McLain, a friend and music executive, are the named executors.
Jackson, according to the source, bequeathed everything he owned to his mother, three children and charitable organizations.
