Thailand
The Civil and Commercial Code of the Kingdom of Thailand does not define ''minor''; however, sections 19 and 20 read as follows:
* Section 19 – A person, on completion of 20 years of age, ceases to be a minor and becomes ''
sui juris''.
* Section 20 – A minor becomes ''sui juris'' upon marriage, provided the marriage is made in accordance with the provisions of Section 1448.
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

The (minimum) age of criminal responsibility in England and Wales, and Northern Ireland is 10. Sentencing guidelines in these three jurisdictions is often tiered, so that a person who is over the age of criminal responsibility (but not of full age), will receive more lenient treatment depending on how old said person is (so for example, punishment will differ between an offender who is under 12, under 14, or under 16, at the time of a given offence, for example, with harsher punishments being received the higher the age of the offender in question).
In Scotland, the (minimum) age of criminal responsibility is 12.
Things that persons under 18 are prohibited from doing include sitting on a jury, standing as a candidate, buying or renting films with an
18 or
R18 classification or seeing them in a cinema, suing without a litigant friend, and purchasing alcohol, or tobacco products.
Driving certain large vehicles, acting as personal license holder for licensed premises, and adopting a child are permitted only upon 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 1971, ''minor'' is generally legally defined as a person under the age of 18. 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, reducing the minimum ages for most privileges that had previously been set at 21 (signing contracts, marrying without parental consent, termination of legal parental custody) to 18.
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.
The
death penalty in the United States 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.
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. Some states, including

Whether an adolescent is able to provide consent for medical care and services depends upon whether they are considered
emancipated minor,

mature minors. This also varies from state to state.
Marriage, military service, or living separately from parents and managing one's own financial affairs usually mean emancipation.

Enemy combatants
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.
