London, Oct 23 Late Michael Jackson's mother Katherine has sacked the lawyers hired to represent her in an ongoing probate case with the executors of the singer's estate.

Katherine is involved in a court battle with the John Branca and John McCain since the King of Pop's death in June (09) regarding some decisions taken by them.

She was left 40 per cent of the net value of the 'Thriller' hitmaker's assets, but she has reportedly been fighting to have a say in all decisions made regarding the singer's estate.

However, Katherine is apparently unhappy with the progress made in the case and has dismissed Burt Levitch from her team of lawyers.

According to TMZ.com, longtime family representative Londell McMillan has also been sidelined in the probate case, although he insists he has not been fired completely.

"I am not completely out," the Daily Express quoted lawyer McMillan as saying. (ANI)
