In many states, guardianship refers to authority over an incapacitated person's personal and medical decisions, while conservatorship refers to authority over their financial affairs and property, and the two can be granted to the same person or to different people depending on the incapacitated person's needs. Other states use the terms differently or use a single term to cover both roles, so the specific division of authority always has to be checked against the governing state's statute rather than assumed from the label alone.

Establishing either arrangement generally requires a court proceeding with notice to the proposed ward or protected person, a clinical evaluation of their capacity, and often the appointment of an attorney or guardian ad litem to represent the proposed ward's interests, reflecting that these proceedings remove significant legal rights and are subject to real due process protections. Most states also favor the least restrictive alternative — limited guardianship or conservatorship tailored to the specific areas of incapacity, or supported decision-making arrangements, rather than a full plenary guardianship stripping all rights when a narrower arrangement would suffice.

Juricratic models a guardianship or conservatorship petition's likely scope — full versus limited — as a dial informed by the specific capacity evidence a user inputs, reflecting the least-restrictive-alternative principle rather than assuming a full plenary arrangement is the default outcome.

Elder law and family attorneys petitioning for guardianship or conservatorship tailor the request to the specific deficits shown by medical evidence, since courts increasingly scrutinize petitions for unnecessarily broad authority, and opposing counsel or the appointed representative for the proposed ward frequently focuses on whether a less restrictive alternative could adequately protect the person.
