Michael Jackson's burial has been further delayed by five days because some family members did not want the pop star to be buried on what would have been his 51st birthday, a lawyer for the singer's mother has said.

Londell McMillan, attorney for mother Katherine Jackson, said there was a miscommunication within the family about the burial date, which had been set for August 29 but has been pushed back to September 3.

``I think there were two dates floated originally,'' McMillan told Reuters, saying some family members wanted Jackson buried on the birthday and others objected, resulting in the change.

The service for friends and family will be held at Glendale Forest Lawn Memorial Park, in a suburb of Los Angeles at 7 pm PDT , family representatives said.

 Jackson suffered cardiac arrest and died on June 25. A police investigation into his death appears focused on his use of prescription drugs and on the doctors who treated him.

Police have raided the home and offices of Jackson's personal doctor, Conrad Murray, who was hired to care for Jackson ahead of a series of London concerts planned for July.

Attorneys for Katherine Jackson faced off in court Friday against the co-administrators of Michael Jackson's estate and the London concerts' promoter, AEG Live, over an AEG-sponsored traveling exhibition of Jackson memorabilia.

Tensions over the estate's administration have risen in recent days, in part, because Katherine Jackson's attorneys have said they could file a wrongful death lawsuit against Murray and name AEG, which paid the doctor, as a co-defendant.

McMillan said Katherine Jackson and others in the singer's family object to the touring exhibition because they believe it is irresponsible to rush into too many business deals, and doing so could undermine a potential wrongful death suit.

``Mrs. Jackson will not approve something that could possibly be used against her if she chooses to file a future lawsuit,'' McMillan said.

A spokesman for AEG could not immediately be reached for comment, nor could representatives for co-administrators John Branca and John McClain. – Reuters
