Those claiming to be heirs to the estate of late music icon Prince will likely have to answer questions under oath, according to new documents from Carver County District Court.

The new proposal – submitted by special administrator Bremer Bank and Trust, the institution appointed to handle the singer’s estate – allows potential heirs one-week after filing a claim to submit a sworn affidavit chronicling their family history.

The affidavit requires answers to a series of personal questions about their parentage, which includes marital history. The alleged heirs will also have to provide a copy of their birth certificate.

Bremer Trust would then decide – within three days – whether genetic testing is required or additional information is needed. Those and other decisions, like failure to comply, can be disputed in the court within three days. Final rulings on those matters is currently set for June 27.

Earlier court papers, filed on May 18, stated that the alleged heirs will have to pay for the testing themselves.

Several people have come forward claiming relation to Prince in the weeks following his April 21 death.

A woman named Brianna Nelson filed an affidavit of heirship on May 18, alleging to be Prince’s niece. Subsequently, the guardian of an 11-year-old girl filed papers claiming that the child is the star’s grandniece. Both claim to be the daughter and granddaughter of Prince’s half-brother Duane Nelson Sr.

In addition, a 39-year-old main who is currently incarcerated has also filed a paternity claim against the estate, alleging that he is the star’s “sole surviving heir.”

Carlin Q. Williams alleged in a May affidavit that his mother had a one-night tryst with Prince in July 1976 – an affair from which he claims he resulted.

Prince’s sister Tyka and five half-siblings are currently working with Bremer Trust to settle the star’s money in and out of court. The 57-year-old left behind no will stipulating to whom his reported $250 million should be bequeathed to.

The “Purple Rain” singer’s cause of death was confirmed as an opioid overdose on Thursday after months of speculation. The singer’s body was released back to his family on April 22.
