LOS ANGELES, (Reuters) – A will signed by Michael  Jackson putting his multimillion-dollar estate in a trust for  his children and mother was filed in court yesterday, as  details of his highly-anticipated funeral remained sketchy.

Some media outlets reported a memorial service would take  place this coming Tuesday at Los Angeles’ Staples Center arena  and others pointed to the city’s Coliseum sports stadium, but a  spokesman for Jackson’s family could not confirm those reports  nor could officials with the venues.

Jackson’s family did issue a statement saying the pop star  would not be buried at his Neverland Valley Ranch in central  California and no funeral or memorial service would take place  there. Media outlets earlier in the week said the family was  considering Neverland as a possible burial ground.

The will values the “Thriller” star’s estate at more than  $500 million, and puts his assets in the Michael Jackson Family  Trust, which ultimately benefits his three children, his mother  and unnamed charities.

It specifically omitted his ex-wife Debbie Rowe, and named  Jackson’s mother, Katherine, 79, as guardian of the children:  Prince Michael Jackson Jr. 12, Paris Michael Katherine Jackson,  11, and Prince Michael Joseph Jackson, II, 7. If Katherine  Jackson cannot fulfill the guardianship duties, singer and  long-time friend Diana Ross was nominated.

Rowe is the mother of the two eldest children, and her  lawyer issued a statement describing as “entirely false” claims  this week that Rowe was not the biological mother.

Before the will surfaced, Katherine Jackson was named  temporary guardian of the children and administrator of the  estate by a Los Angeles court until a hearing on July 6.

But the 2002 will names Los Angeles attorney John Branca  and music executive John McClain as co-executors. They asked a  Los Angeles judge to overturn Katherine Jackson’s  administration of the estate yesterday, but the judge denied  their request and put off a decision until Monday’s hearing.

Since his death last week, speculation has run rampant that  there would be multiple wills and a legal battle over Jackson’s  estate, which includes part ownership in a Beatles music  catalog and Jackson’s own music company.

Jackson was said to be $500 million in debt when he died,  but his assets have been reported to be worth as much as $1  billion, which would roughly approximate the will’s estimated  value of Jackson’s estate that “exceeds $500 million.”
