On Tuesday morning, Prince’s sister Tyka Nelson filed an emergency petition for the appointment of a special administrator, according to Minnesota court documents obtained by PEOPLE.
“I do not know of the existence of a Will and have no reason to believe that the Decedent executed testamentary documents in any form,” states the document, which was filed in Carver County.
Nelson, whose address is listed in Minneapolis, Minn, requested the appointment of Bremer Bank, which handled the singer’s personal and business finance services for years.
“[I]mmediate action and decisions need to be made to continue the ongoing management and supervision of the Decedent’s business interests,” according to the petition.

The document also lists the singer’s other heirs, which include his half-brother John Nelson; half-sister Norrine Nelson; half-sister Sharon Nelson; half-brother Alfred Jackson; and half-brother Omar Baker.

Still, some of these siblings and possibly other relatives may be unaware of their status. Among the many tasks for the appointed administrator is locating everyone listed, as the document states, “The Decedent has heirs whose identities and addresses need to be determined.”
With so much at stake – the singer’s estate is approximated at $250 million – and a number of heirs listed, estate expert and attorney Jeffrey P. Scott told People, “I would be really surprised if there weren’t objections and contests in court. There’s a lot of money involved.”
