Definition - What does Minor mean?
A minor is a person who is too young to be deemed capable of being fully responsible for himself or herself legally. Typically, this refers to people under the age of 18. Most states consider people who are 18 and over to no longer be minors. This means that they can sign their own contracts and make other important legal decisions.
Justipedia explains Minor
A minor basically refers to a person who is under 18 years of age. Whether or not a person is a minor is an important classification for many legal issues. For example, minors cannot join the military, cannot buy tobacco, cannot independently sign their own contracts in many cases, etc. The reason why there are so many restrictions placed on minors is because society believes that they are too inexperienced and underdeveloped to possess the required knowledge for such issues.
