Katherine Jackson has filed to a petition become the administrator of Michael Jackson's estate to ensure his three children are its beneficiaries.
The documents filed Monday in Los Angeles state that Jackson's mother should be appointed as the estate's administrator.
Joe Jackson has joined in the petition to try to designate his wife as keeper of the pop icon's estate.
