What is the legal term for a person placed under the care of a guardian by court order?

The legal term for a person placed under the care of a guardian by court order is "Ward." In the legal context, a ward is an individual who has been deemed unable to manage their own affairs, typically due to age, incapacity, or some other reason that limits their ability to make decisions. A court appoints a guardian to oversee the welfare and interests of the ward, ensuring their needs are met and providing necessary support.

The term "vendee" refers to a person who purchases goods or property, which is unrelated to guardianship. "Parties" typically refers to individuals or entities involved in a legal proceeding. "Recidivist" pertains to a person who repeatedly commits offenses, particularly in the context of criminal law. Therefore, the answer accurately identifies the correct legal designation for someone under a guardian's care.
