A guardian must obtain court approval before consenting to which action regarding a ward?

A guardian must obtain court approval before consenting to committing the ward to an institution because such a significant decision has considerable implications for the ward's well-being, autonomy, and rights. Institutionalization involves removing an individual from their home environment, which can greatly affect their living situation and overall quality of life. Due to the potential impact of this action, it is critical for the guardian to have the court's oversight and approval, ensuring that such a decision is in the best interest of the ward and thoroughly examined in the context of their needs, preferences, and alternatives.

In contrast, routine medical treatment typically falls under the guardian's authority, as these decisions are often deemed necessary for the ward's health and do not require extensive scrutiny. Similarly, providing day-to-day care involves managing the ward's daily activities and needs, which is a normal duty of a guardian. Signing legal documents, while significant, generally does not require court approval unless it involves matters that exceed the guardian’s authority or have legal implications requiring judicial oversight.
