Conservatorship is a legal concept in the United States of America, where an entity or organization is subjected to legal control of an external entity or organization, known as a conservator.
Conservatorship is established either by court order or via a statutory or regulatory authority. A person under conservatorship is a “conservate,” a term which can refer to an adult. A conservatorship may refer to the legal responsibilities over a person who is mentally ill, including individuals who are psychotic, suicidal, incapacitated, or in some other way unable to make legal, medical or financial decision on behalf of them.
Britney Spears has been under "conservatorship" by her father since 2008, meaning he is in charge of all her legal and financial decisions, something that is usually used on for people with Alzheimer's or severe mental illness.Thanks to this action Britney avoided to fall even deeper into her depression.
