LOS ANGELES - Michael Jackson's 7-year-old will was filed Wednesday in a Los Angeles court, giving his entire estate to a family trust but cutting out his former wife Debbie Rowe.

The will, dated July 7, 2002, estimated his estate at that time at more than US$500 million.

It gives the entire estate to the Michael Jackson Family Trust.

The documents said Jackson's estate consisted almost entirely of "non-cash, non-liquid assets, including primarily an interest in a catalogue of music royalty rights which is currently being administered by Sony ATV, and the interests of various entities."

His mother, Katherine Jackson, is named as a beneficiary of the trust and the guardian of Jackson's children, who are named in the will.

The will names Diana Ross as a successor guardian to Jackson's mother if necessary.

It also names Jackson's longtime lawyer John Branca and John McClain, a music executive and a family friend, as co-executors of the will.

In a statement, Branca and McClain said: "The most important element of Michael's will is his unwavering desire that his mother, Katherine, become the legal guardian for his three children."

"As we work to carry out Michael's instructions to safeguard both the future of his children as well as the remarkable legacy he left us as an artist we ask that all matters involving his estate be handled with the dignity and the respect that Michael and his family deserve."
