Michael Jackson’s parents, Katherine and Joe Jackson, have filed a petition in Los Angeles Superior Court to probate their son’s estate, PEOPLE has confirmed.
According to legal papers, the Jacksons state that their son “died intestate,” meaning without a will. Katherine Jackson, who has already filed for custody of her grandchildren Prince, 12, Paris, 11 and Prince Michael II, 7, is seeking to take possession of her son’s assets for “for the exclusive use of [his] three children.”
The papers also state that, according to California law, Jackson’s children are the sole beneficiaries of his estate.
In her original custody filing, Jackson claims that her grandchildren have “no relationship with their biological mother” and have been in her care since Michael’s death. A hearing on the custody matter is scheduled for July 6.
