Michael Jackson's mother wants to sue the promoters of his London comeback shows.
Katherine Jackson claims the pressures of the 50-date residency which her son was talked into led to his death.
She is believed to be targeting both the promoters behind the shows, AEG, and Michael's personal doctor, Conrad Murray, in a $100 million wrongful death lawsuit.
Katherine's lawyer Burt Levitch said: "The possibility of a wrongful death action has been floated."
"In that regard, no decision has been finalized. Dr. Murray's name has been put forward because he is under investigation."
"It's fairly obvious from press accounts that AEG had a very active role in Michael's life for the last six months. They paid for his home and for Dr. Conrad Murray."
Katherine may sue for her son's loss of earnings and her emotional distress.
Michael died of a suspected cardiac arrest in June, after reportedly ingesting a cocktail of prescription drugs.
Dr. Murray was with him at the time of his death, and is alleged to have administered powerful anesthetic Propofol.
Michael was rehearsing for his comeback shows at the time of his death, and his family believe he turned to drugs to get through his grueling preparation schedule for the performances.
A spokesperson for AEG said: "It would be inappropriate to speculate on any potential litigation."
Meanwhile, the Jackson family have confirmed Michael will be buried on August 29, which would have been his 51st birthday.
The service will take place at 10am at Los Angeles' Forest Lawn Memorial Park cemetery.
