Tom Petty's daughters are suing his widow for $5million in damages over the late singer's unreleased music in the latest familial dispute over his estate.
Petty Unlimited was set up to manage Petty's affairs after his death and was supposed to be run by his daughters, Adria and Annakim, and his widow, Dana Petty.
The suit is seeking compensatory damages "in excess of $5 million according to proof at trial, punitive and exemplary damages, recovery of Petty's assets from Dana and the establishment of a "constructive trust" in the plaintiff's favour over all assets "wrongfully" in the defendants' possession".
Adam Streisand, Dana Petty's attorney, issued a statement calling the suit "destructive nonsense".
Petty passed away in October 2017, with the coroner concluding he died from an "accidental drug overdose as a result of taking a variety of medications", including "fentanyl".
"This misguided and meritless lawsuit sadly demonstrates exactly why Tom Petty designated his wife to be the sole trustee with authority to manage his estate", he said.
Her late husband left Dana in charge of his legacy and recordings but insisted his two daughters from a previous marriage had a say in all major decisions.
Tom Petty's latest release is The Best of Everything, which came out earlier this year.
She also asked the court to execute an operating agreement to appoint a manager to oversee day-to-day matters alongside herself and Petty's daughters, according to documents previously obtained by PEOPLE.
In April, Dana Petty filed a probate to put the catalog in the hands of a professional manager.
Dana's petition also alleged that Adria exhibited "erratic behaviour" towards herself, in addition to Petty's managers, record labels and former bandmates, claiming her actions "made it exceedingly - and increasingly - hard to carry on business and has threatened the Trust's business dealings and important relationships with the Heartbreakers, Tom's record labels (which are critical to the ongoing success of the franchise), and Tom's longstanding management team". She argued that Adria Petty had been erratic and abusive, and had made it hard to conduct business in an orderly way.
She goes on to cite specific instances, claiming that both daughters dragged their feet over a potential greatest hits compilation, and rejected a million-dollar offer to release an expanded 25th-anniversary edition of the album Wildflowers without consulting her. Adria responded by filing her own probate to claim control of the estate.
