A conservatorship is an entity establishe by court order that some property or a person be subject to the legal control of another person or entity, known as a conservator. Many jurisdictions use the term "guardianship of the person" to refer to the same legal principle. A person under conservatorship is a conservatee or protected person; a person under guardianship is a ward. In most states, a court visitor or some other investigatory person or agency must review the facts of the case and submit a report, usually required to be in writing, to the court. Court visitors are often required to be experts in some appropriate field, such as social work or law. Additionally, states may require a "guardian ad litem" to be appointed for the person. The guardian ad litem often is an attorney, but has more expanded duties and powers than an attorney. Procedures for conservatorship of an adult are often different from those for minors.
