The 54-year-old mother of Michael Jackson's eldest children, Paris and Prince, will replace the pop superstar's nephew, Tito Jackson Jr., as co-guardian with Katherine Jackson.
Tito was appointed co-guardian of the King of Pop's three children last year (12).
A lawyer formerly associated with the family's legal matters tells the New York Post that an upcoming hearing on 15 October (13) will deal with the removal and appointment of a guardian.
The new arrangement would reportedly pave the way for Paris to leave Katherine's home and move in with her mother in Palmdale, California.
However, the financial agreement would stay the same for all parties. Katherine currently receives $86,000 (£57,330) a month from Michael's estate, with approximately $20,000 (£13,330) going to Paris' expenses.
A source says, "Debbie will get whatever Paris may need in terms of resources, but (Katherine) will continue to be in control of most things, including when and how some of the monies are disbursed."
Paris has been undergoing psychological treatment in California since her alleged suicide attempt in June (13).
