Los Angeles (CNN) -- A judge appointed TJ Jackson, the 34-year-old son of Tito Jackson, as temporary guardian of Michael Jackson's three children in the absence of their grandmother, Katherine Jackson. 

"We have reason to believe that Mrs. Jackson has been held against her will," Katherine Jackson attorney Sandra Ribera told Los Angeles County Superior Court Judge Mitchell Beckloff at a hearing Wednesday. 

Immediately after the hearing however, another attorney for Jackson, Perry Sanders, said he had been told by Randy Jackson that his mother was on her way back to California. 

Sanders, who later spoke to his client as she was being driven home, said he will file a petition to restore her as custodian as soon as he meets with her. Katherine Jackson was unaware of the controversy swirling around her family for the past week, he said.

Beckloff suspended Katherine Jackson as custodian for Prince, Paris and Prince Michael II, known as Blanket, because she may be "prevented from acting as a guardian because of the acts of third parties." 

He also ordered "that the children not be removed from California without a court order, by any person." 

The judge also ordered that Diana Ross, whom Michael Jackson named as backup guardian in his will, and Debbie Rowe, the biological mother of the two oldest children, be given notice of the order. 

The order will be reconsidered at a hearing next month, and the judge left open the possibility that custody could be returned sooner if Katherine Jackson returns home.
