A minor, often referred to as a child, is a person who is not yet legally considered an adult. The age at which someone is classified as a minor varies by country, but it is commonly set at 18 years. Minors typically have limited legal rights and responsibilities compared to adults, which means they cannot enter into contracts or make certain legal decisions without parental consent. In many societies, the welfare of minors is protected by laws and regulations. These laws aim to ensure that children, such as those in foster care or school systems, receive proper care, education, and protection from harm. Additionally, minors are often subject to different legal standards in cases involving criminal justice or family law.
