A judge on Monday approved a deal for the sale of products in the image of the late Michael Jackson.
Meanwhile an attorney for the singer's mother says she's considering filing a wrongful death lawsuit.
Attorney Burt Levitch, representing the pop star's mother, Katherine says she may file a wrongful death lawsuit because of the circumstances surrounding her son's demise.
One possible defendant, Dr. Conrad Murray, the singer's personal physician.
"Dr. Murray's name has been floated because he is apparently under criminal investigation," said attorney Burt Levitch.
That investigation, apparently focused on the possibility Murray may have improperly given Jackson a powerful anesthetic that's usually only administered in a hospital.
Police are also looking into actions of other doctors who had been treating Jackson and the role prescription drugs may have played in his death.
Asked whether concert promoter AEG might also be a defendant in a wrongful death suit, Levitch refused to answer but said AEG had an active role in the last six months of Jackson’s life, paying his rent and hiring Murray at the singer's request. .
"In that regard there's an obviously link between AEG and concerns that we have about the decedents demise," Levitch said.
In a development relating to the estate, a judge on Monday approved a deal between the co-executors of the singer's will and Bravado International Group which clears the way for the sale of merchandise in Jackson’s image.
The judge delayed until Friday a decision on a traveling exhibition of Jackson memorabilia after hearing objections from Katherine Jackson’s attorney about allowing the exhibition.
"There have been some opportunities that we may lose or in fact have lost because of the delays caused by Mrs. Jackson’s objection," said Howard Weitzman, attorney for the executors of the will.
Earlier this month the judge approved a deal between Jackson’s estate, AEG and Columbia Pictures for a movie to be released in October using footage from the final rehearsals.
