Prince's siblings say a woman and girl purported to be the singer's niece and grandniece, have no genetic connection to Prince and should not be named as heirs to his estate.
Attorney's for Prince's siblings and half-siblings argued in documents made public Tuesday that Brianna Nelson and Victoria Nelson aren't Prince's heirs as a matter of law, and a judge should deny their claims. A hearing is set for Friday.
Prince died April 21 of a fentanyl overdose, leaving no known will.
Brianna Nelson and her niece, Victoria Nelson, claim they descend from the late Duane Nelson Sr., who they say was Prince's half-brother. They do not claim a genetic link, but say Prince's biological father held Duane Nelson out as his son.
Prince's siblings say that isn't enough to prove heirship.
