It was reported that Michael Jackson’s estate was planning to sell the pop star’s music catalog in a deal that was supposed to net around $800 to $900 million.

Despite the reports, it was noted that MJ’s 92-year-old mother Katherine Jackson didn’t approve of the possible deal, asking the courts to reject it. Now, Katherine Jackson will be testifying in a trial related to the estate of her son. Jackson is set to show evidence against John McClain and John Branca, who are administrators and executors of Michael Jackson’s estate. Branca and McClain have been running Jackson’s estate since his passing in 2009. It was noted the estate asked the court to sign off on a deal they secured, with both people saying there is “an opportunity which they believe is to the substantial advantage of the Estate and in the best interest of the beneficiaries.” The estate sealed the details of the proposed deal and Katherine Jackson rejected it. The estate then reacted, saying they turned around the finances for MJ following his death, saying he was over $400 million in debt. The new filing will find Jackson testifying in court along with McClain and Branca.
