LOS ANGELES, California (CNN) -- The newly named lawyer for Michael Jackson's children makes her first court appearance Monday as a judge decides if he'll approve a contract between Jackson's estate and concert promoter AEG Live. Michael Jackson's estate will be the subject of a court hearing today. Jackson's mother, Katherine Jackson, who has custody of the three children, objected to provisions of the deal that would give AEG Live a share of rights to video of her son's final rehearsals. Los Angeles County Superior Court Judge Mitchell Beckloff appointed estate law expert Margaret Lodise last week to represent the children after he decided their interests might sometimes conflict with their grandmother's.
