What is a sibling's role in a conservatorship?

It sounds as if you already know that a conservatorship proceeding begins when a petition is filed to have a person called conservator appointed to manage a person's personal needs or finances, or sometimes both. At that stage, all close relatives of the person, including siblings, must be notified of the petition.

But once a conservatorship is established, a sibling has no specific rights or duties in the arrangement -- unless he or she has been named the conservator.
