Prince's sister Tyka has filed legal docs to open a probate case because she says that the singer did not leave a last will, reports TMZ. Uh oh!

In the documents, which were filed in Minnesota, Tyga asks the judge to appoint a "special administrator," who is someone who is appointed when a will has no executor.

Tyka says in the documents, "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." 

If Prince died without a will then the estate will be divided among his sibling (Tyka) and half siblings, John, Norrine, Sharon, Alfred and Omarr, whom Tyka listed as the potential beneficiaries. They are the living siblings of Prince.  

The outlet is quick to point out that Tyka also named Lorna (who is a deceased half sister with no kids) as a potential beneficiary. Under Minnesota law Lorna will not get assets because she is dead, so it's odd that Tyka listed her but did not list Duane, another of Prince's half brothers, who is also deceased.

Interestingly, there's also a line in the documents that says, "The decedent has heirs whose identities and addresses need to be determined."

Tyka names Bremer Trust, National Association as the official administrator of Prince's estate. She says the Bremer has been taking care of Prince's finances for years and is best suited to protect his assets.
