Prince’s sister Tyka Nelson was involved in the purple empire long before his death, and since then she has become the public face of the estate, of which she is an heir along with five of Prince’s half-siblings. In legal matters, it was Nelson who first petitioned for a professional entity to manage the estate. Currently that is Comerica Bank, which has authority in intellectual property rights, but Nelson’s public persona and full-relation status give her unofficial prominence. They also put her in the crosshairs of fans, whether outraged by a Prince song in a recent TV commercial or suspicious that Nelson’s using the spotlight to advance her own singing career. There is much money to be made from a treasure trove of unreleased Prince music and monetization of his existing catalog. Nelson’s out-front role will make her the go-to persona of those inevitably controversial choices.
