When a person dies in Nevada without leaving a valid will, an administrator may be appointed by the court to step in and manage their affairs. A Petition for Appointment of Administrator is usually filed when the person who died owned significant assets worth more than $100,000, like bank accounts, real estate (like a home), or personal items. The person who files this petition wants the court to appoint someone (usually themselves) to gather and protect these assets, pay any outstanding bills and taxes, and then distribute everything to the legal heirs as determined by Nevada law.
