What does plenary guardianship entail?

Plenary guardianship involves the complete delegation of decision-making authority from the ward to the guardian. This means that all delegable rights of the ward have been removed, allowing the guardian to make decisions relating to personal, financial, and medical matters on behalf of the ward without the ward retaining any authority in those areas.

In contrast, the other options describe different forms of guardianship or levels of authority. For example, if a ward retains partial rights, this denotes a form of limited guardianship rather than plenary. Temporary oversight implies that the arrangement isn't permanent, which is not the case with plenary guardianship, where the guardian has ongoing authority until the guardianship is terminated. Shared decision-making authority suggests collaboration and does not align with the nature of plenary guardianship, wherein the guardian holds full power over decisions without needing input from the ward.
