The mature minor doctrine is a statutory, regulatory, or common law policy accepting that an unemancipated minor patient may possess the maturity to choose or reject a particular health care treatment, sometimes without the knowledge or agreement of parents, and should be permitted to do so. It is now generally considered a form of patients rights; formerly, the Mature Minor Rule was largely seen as protecting health care providers from criminal and civil claims by parents of minors at least 15 years of age.
