The company is owned by concert promoter AEG Live, which was behind Jackson's planned comeback tour in London.
Burt Levitch, a lawyer for the singer's mother, said she had concerns about various parts of the deal, which will see a collection of Jackson-related items tour three cities.
"Mrs Jackson still feels there are certain aspects of the AEG agreement that could have been improved upon. This is not about making a quick buck, it's about protecting the long-term legacy of one of the most famous performers of all time," Levitch told reporters outside the courthouse.
Katherine Jackson's attorneys said the family was concerned that the contract for the exhibition would not be subject to an open bidding process, and also objected to the 50-50 split of proceeds between AEG and the family.
AEG has said it intends to launch the tour alongside a film culled from footage of the late pop icon rehearsing for his final tour.
Taj Jackson, the performer's nephew and personal assistant, also testified at the hearing, emphasizing that his uncle was "a perfectionist."
"He was very protective of his image and he wouldn't want anything that wasn't perfect up there," he said.
AEG has not confirmed which three cities will host the show, but the first stop is expected to be London's O2 Center, where Jackson was set to open his final tour of 50 concerts.
Jackson died in Los Angeles on June 25, aged 50, after suffering an apparent cardiac arrest -- but the cause of his death remains unclear and police are investigating.
