MUMBAI: A Los Angeles judge has said that Michael Jackson‘s mother, Katherine Jackson can challenge the administrators of his estate without losing her share in a lucrative family trust, it is gathered.

Attorneys of Jackson’s mother have said that she wants a greater say in the way her son’s estate estimated to be worth about $400 million is administered. It was not immediately known if she would now formally lodge a challenge.

It may be recalled that Jackson appointed his longtime attorney John Branca and music executive John McClain as executors of his estate in a 2002 will. Katherine Jackson‘s attorneys had asked the Court to suggest whether she could make the challenge without violating a "no contest" clause in the family trust.

The family trust provides Katherine Jackson, 79, with 40 percent of the estate, the singer‘s three children with another 40 per cent and children‘s charities with 20 per cent.

According to Friday‘s court documents, Judge Mitchell Beckloff ruled that Katherine Jackson would not violate the no contest trust clause by mounting a challenge.
