LOS ANGELES , California ( CNN ) -- Michael Jackson 's mother fired the lawyers helping her fight for control of her son 's estate , but her new lawyer missed a key hearing where the judge gave more power to the men she is opposing . Katherine Jackson , with Michael in 2005 , is challenging the appointment of Michael 's estate trustees . Katherine Jackson replaced lawyers Burt Levitch and Londell McMillan with Adam Streisand , a lawyer known for his expertise in Los Angeles probate cases . `` The family came to a decision before they called me , '' Streisand said . `` They felt they needed a different perspective and fresh look at how this case was being approached . '' But Streisand arrived at court Thursday minutes after Los Angeles Superior Court Judge Mitchell Beckloff ended a hearing in which he granted a request from estate special administrators John Branca and John McClain for more authority to make deals on behalf of Jackson 's estate . `` I want this estate to move forward and I want these creditors to be dealt with , '' Beckloff said . `` And while we are proceeding in this posture , I want Mrs. Jackson to have information about what is going on and I do n't want to be in court all the time . '' The process of probate of Jackson 's will , which named Branca and McClain as executors , has been slowed since soon after the pop star 's June 25 death by numerous legal challenges filed by Katherine Jackson 's lawyers , led by Levitch . Howard Weitzman , lead lawyer for the estate 's administrators , expressed optimism that the two sides would be able to work better toward a settlement with Streisand in charge . The estate 's administrators were able to make a series of deals expected to bring in at least $ 100 million to the estate this year , mostly through a documentary movie that premieres next week . Katherine Jackson 's legal team has asked that a member of the Jackson family `` have a seat at the table '' as a third executor . They 've also raised questions in sealed court papers about possible conflicts of interest that might prevent Branca and McClain from controlling the estate . Streisand said the Jackson family was frustrated with the inability `` to get this case going . '' He indicated Katherine Jackson still planned to challenge Branca and McClain 's control of her son 's wealth . Under the 2002 will , Michael Jackson 's three children and his mother are the chief beneficiaries of his estate , while unnamed charities will share in 20 percent of the wealth . Streisand said when he met with Katherine Jackson and the children to discuss the case , they were united . He said Jackson patriarch Joe Jackson was not present at the meeting and he 's never talked with him . Joe Jackson appeared frustrated earlier this month when he attended his first hearing in the probate process , suggesting the lawyers should be more aggressive in court . Streisand said the three Jackson children are doing `` absolutely wonderful . ''
