What powers does a Plenary Guardian have?

The correct choice reflects that a Plenary Guardian is granted the authority to exercise all delegable legal rights and powers of the ward. This encompasses a comprehensive set of responsibilities and authorities which may include, but are not limited to, medical decisions, financial management, and general welfare considerations. A Plenary Guardian acts on behalf of the ward, ensuring that their best interests are upheld in various aspects of life, from health care to handling property and finances.

The scope of a Plenary Guardian's powers is designed to provide them with the necessary tools to make informed decisions that affect the ward's overall quality of life. This is crucial in circumstances where the ward can no longer make these decisions themselves due to incapacity or other challenges.

In contrast, the other choices are limited in scope and do not accurately depict the comprehensive nature of a Plenary Guardian's authority. The focus on specific areas such as health care decisions or property management does not encapsulate the full range of powers a Plenary Guardian holds, which is why they do not align with the responsibilities typically granted under this designation. Additionally, stating that no powers exist unless specified by the court undermines the inherent authority that comes with being appointed as a Plenary Guardian.
