The statement "Parents patriae is the notion that your parents have a legal duty to act in the best interests of their children until they reach the age of 21" is false.
Parents patriae is a Latin term that means "fathers of the nation" or "fathers of the country." It refers to the state's authority and responsibility to protect the welfare and rights of its citizens, especially children, who are unable to protect themselves. In the legal context, parents patriae refers to the state's power to intervene in matters involving the welfare of children, such as child abuse, neglect, or abandonment.
In most countries, parents have a legal duty to provide for the basic needs of their children, including food, shelter, clothing, and medical care. This legal duty usually extends until a child reaches the age of majority, which is the age at which a person is legally considered an adult and is no longer under the control of their parents. The age of majority varies by jurisdiction, but it is typically 18 or 21 years old.
In summary, parents patriae is a legal concept that refers to the state's authority to protect the welfare and rights of children, but it does not impose a specific legal duty on parents to act in the best interests of their children until they reach a certain age.
