Minor (law)

In law, a minor is a person under a certain age, usually the age of majority, which legally demarcates childhood from adulthood. The age of majority depends upon jurisdiction and application, but it is generally 18. "Minor" may also be used in contexts that are unconnected to the overall age of majority. For example, the drinking age in the United States is usually 21, and younger people are sometimes called "minors" in the context of alcohol law, even if they are at least 18. The term underage or minor often refers to those under the age of majority, but it may also refer to a person under other legal age limits, such as the drinking age, smoking age, age of consent, marriageable age, driving age, voting age, etc. Such age limits are often different from the age of majority. 
The concept of "minor" is not sharply defined in most jurisdictions. The age of criminal responsibility and consent, the age at which school attendance is no longer compulsory, the age at which legally binding contracts can be entered into, and so on may be different from one another.
In many countries, including Australia, India, Brazil, Croatia, and Colombia, a minor is defined as a person under the age of 18. In the United States, where the age of majority is set by individual states, "minor" usually refers to someone under 18 but can in some areas (such as alcohol, gambling, and handguns) mean under 21. In the criminal justice system a minor may be tried and punished either "as a juvenile" or "as an adult".
In Japan, Taiwan, and Thailand, a minor is a person under 20 years of age. In New Zealand law, the age of majority is 20 years of age as well, but most of the rights of adulthood are assumed at lower ages: for example, entering contracts and having a will are allowed at 15, while the drinking and voting age are both at 18.
International.
Canada.
For all provincial laws (such as alcohol and tobacco regulation), the provincial and territorial governments have the power to set the age of majority in their respective province or territory, and the age varies across Canada.
Alberta, Manitoba, Ontario, Quebec, Saskatchewan, and Prince Edward Island have the age of majority set at 18, while in British Columbia, Yukon, Northwest Territories, Nunavut, Newfoundland, Nova Scotia, and New Brunswick the age of majority is 19. In Saskatchewan, the legal gambling age and the legal drinking age are both 19.
Italy.
In Italy, law nr. 39 of March 8, 1975, states that a minor is a person under the age of 18. Citizens under the age of 18 may not vote (to vote for senators, 25), be elected, obtain a driving license for automobiles or issue or sign legal instruments. Crimes committed in Italy by minors are tried in a juvenile court.
Mexico.
In all 31 states, a minor is referred to as someone under the age of 18.
Minors aged 16 or 17 who are charged with crimes could sometimes be treated as an adult.
India.
In all 28 states and 8 union territories, a minor is referred to as someone under the age of 18. In rare cases minors aged 16 or 17 who are charged with extremely heinous crimes could sometimes be treated as an adult.
Thailand.
The Civil and Commercial Code of the Kingdom of Thailand does not define "minor"; however, sections 19 and 20 read as follows:
Hence, a minor in Thailand refers to any person under the age of 20, unless they are married. A minor is restricted from doing juristic actsfor example, signing contracts. When minors wish to do a juristic act, they have to obtain the consent from their legal representative, usually (but not always) the parents and otherwise the act is voidable. The exceptions are acts by which a minor merely acquires a right or is freed from a duty, acts that are strictly personal, and acts that are suitable to the person's condition in life and are required for their reasonable needs. A minor can make a will at the age of fifteen.
United Kingdom.
In England and Wales and in Northern Ireland a minor is a person under the age of 18; in Scotland that age is 16. The age of criminal responsibility in England and Wales and in Northern Ireland is 10; and 12 in Scotland, formerly 8, which was the lowest age in Europe.
In England and Wales, cases of minors breaking the law are often dealt with by the Youth Offending Team. If they are incarcerated, they are sent to a Young Offender Institution.
Things that persons under 18 are prohibited from doing include sitting on a jury, voting, standing as a candidate, buying or renting films with an 18 certificate or R18 certificate or seeing them in a cinema, being depicted in pornographic materials, suing without a litigant friend, being civilly liable, accessing adoption records and purchasing alcohol, tobacco products, knives and fireworks. The rules on minimum age for sale of these products are frequently broken so in practice drinking and smoking takes place before the age of majority; however many UK shops are tightening restrictions on them by asking for identifying documentation from potentially underage customers.
Driving certain large vehicles, acting as personal license holder for licensed premises, and adopting a child are permitted only after the age of 21. The minimum age to drive a HGV1 vehicle was reduced to 18. However, certain vehicles, e.g., steamrollers, require that someone be 21 years of age to obtain an operating license.
United States.
In the United States as of 1995, "minor" is generally legally defined as a person under the age of 18. However, in the context of alcohol or gambling laws, people under the age of 21 may also sometimes be referred to as minors. However, not all minors are considered juveniles in terms of criminal responsibility. As is frequently the case in the United States, the laws vary widely by state.
Under this distinction, those considered juveniles are usually (but not always) tried in juvenile court, and they may be afforded other special protections. For example, in some states a parent or guardian must be present during police questioning, or their names may be kept confidential when they are accused of a crime. For many crimes (especially more violent crimes), the age at which a minor may be tried as an adult is variable below the age of 18 or (less often) below 16. For example, in Kentucky, the lowest age at which a juvenile may be tried as an adult, no matter how heinous the crime, is 14.
The death penalty for those who have committed a crime while under the age of 18 was discontinued by the U.S. Supreme Court case "Roper v. Simmons" in 2005. The court's 5–4 decision was written by Justice Kennedy and joined by Justices Ginsburg, Stevens, Breyer, and Souter, and cited international law, child developmental science, and many other factors in reaching its conclusion.
The twenty-sixth amendment to the U.S. Constitution, ratified in 1971, granted all citizens the right to vote in every state, in every election, from the age of 18.
The U.S. Department of Defense took the position that they would not consider "enemy combatants" held in extrajudicial detention in the Guantanamo Bay detainment camps minors unless they were less than sixteen years old. In any event, they separated only three of more than a dozen detainees under 16 from the adult prison population. Several dozen detainees between sixteen and eighteen were detained with the adult prison population. Now those under 18 are kept separate, in line with the age of majority and world expectations.
Some states, including Florida, have passed laws that allow a person accused of an extremely heinous crime, such as murder, to be tried as an adult, regardless of age. These laws have been challenged by the American Civil Liberties Union. An estimated 250,000 youth are tried, sentenced, or incarcerated as adults every year across the United States.
Emancipation of minors.
Emancipation of minors is a legal mechanism by which a minor is no longer under the control of their parents or guardians, and is given the legal rights associated with adults. Depending on country, emancipation may happen in different manners: through marriage, attaining economic self-sufficiency, obtaining an educational degree or diploma, or participating in a form of military service. In the United States, all states have some form of emancipation of minors.
