Prince performing during his concert at the Zenith venue in Paris on Aug. 25, 1986

Less than a week after his death, Prince's sister Tyka Nelson has verified that the icon died without a will.

According to the Associated Press, Nelson is now seeking the Minneapolis courts' help in appointing an administrator to oversee the estate. Although Prince has a number of siblings, Nelson is his only full sister.

Nelson has requested that Bremer Trust, a corporate trust company, be named administrator. There is no confirmed assessment of how much Prince's estate is worth, but figures ranging from $27 million to over $200 million have been thrown around. According to insiders, Prince's infamous vault of music could also carry a huge price tag.
