Underwriters at Lloyds of London filed a lawsuit against AEG Live and Jackson's company in Los Angeles Superior Court on Monday, asking a judge to solve the insurance dispute almost two years after the "Thriller" singer's death. Jackson, 50, died in Los Angeles on June 25 after rehearsing for the upcoming series of 50 concerts in London.

Authorities said he died of a massive dose of the anesthetic propofol and a cocktail of other sedatives and painkillers. The insurance policy was taken out to cover the cancellation or postponement of the London concerts in the case of the death, accident or illness of Jackson.

The lawsuit claimed that AEG, who hired Jackson's physician Dr. Conrad Murray, failed to disclose the singer's medical history to the insurers "including, but not limited to, his apparent prescription drug use and/or drug addiction."
