What authority do letters of guardianship grant to the guardian?

Letters of guardianship grant the guardian the authority to act on behalf of the individual. This overarching authority encompasses various responsibilities, which can include making decisions related to health care, finances, and daily living needs, depending on the specific terms of the guardianship established by the court. When a guardian is appointed, they essentially step into the shoes of the individual they are representing, enabling them to make choices that the individual would make if they were capable of doing so.

While the other options touch on specific roles and responsibilities that a guardian may have, they are aspects of the broader authority granted by the guardianship. The power to act on behalf of an individual encompasses all these aspects, allowing the guardian to ensure that the individual's best interests are taken into account across all areas of their life, thus making option C the most comprehensive and accurate representation of the authority provided by letters of guardianship.
