Without POA in place, the state may appoint a third party to help an indisposed principal. With financial estate management, probate courts may appoint a guardian or conservator to manage someone's property. Family members can petition for access to the principal's finances when this occurs. If someone becomes medically incapacitated, family members will make decisions in place of an agent. Medical staff will act in the patient's best interest if the hospital cannot contact relatives. If the patient left a will, it provides a roadmap to medical staff.
