Legal Capacity at 16: Coming of Age in Scots Law
Contents
In Scotland, sixteen is a significant age. Since the Age of Legal Capacity (Scotland) Act 1991, sixteen-year-olds have generally had full legal capacity to make contracts and manage their own affairs. Scots law has long allowed sixteen-year-olds to marry without their parents' consent, which made Gretna Green famous. And since 2015, sixteen-year-olds can vote in Scottish Parliament and local elections. This card explains how Scots law treats young people, and how it differs from the rest of the UK.
TL;DR
- established The Age of Legal Capacity (Scotland) Act 1991 gives people aged 16 and over general legal capacity to enter into transactions, such as contracts.
- established Under 16s have limited capacity: for example, they can make a will and consent to adoption from age 12, and can consent to medical treatment if a doctor judges they understand its nature and consequences.
- established Before 1991, Scots law used the categories of pupils (girls under 12, boys under 14) and minors, a system inherited from Roman law.
- established In Scotland, people aged 16 can marry without parental consent, a long-standing difference from England that made Gretna Green a destination for eloping couples. England raised its minimum marriage age to 18 in 2023.
- established The Scottish Elections (Reduction of Voting Age) Act 2015 gave 16- and 17-year-olds the vote in Scottish Parliament and local elections, following their participation in the 2014 independence referendum.

A Note on Claims and Evidence
Each major claim carries one of three labels. established means supported by primary records, official bodies or several independent reliable sources. shared means the core fact is sound but sources disagree on details, dates or interpretation. traditional means widely repeated but not traceable to a primary or independent source.
This card summarises the law and is not legal advice. Some protections continue between 16 and 18, such as the right to challenge prejudicial transactions.

Details
Pupils and minors
established Traditionally, Scots law divided young people into pupils, girls under 12 and boys under 14, who had no legal capacity and acted through a tutor, and minors, from those ages until majority, who could act with the consent of a curator. The system came from Roman law.
The 1991 Act
established The Age of Legal Capacity (Scotland) Act 1991 replaced this system. Under 16s generally lack capacity to enter transactions, except those common for their age on reasonable terms, such as buying everyday items. From age 12, a young person can make a will and must consent to their own adoption. A person under 16 can consent to medical or dental treatment if a qualified practitioner considers them capable of understanding its nature and possible consequences. From 16, a person has full capacity to enter into transactions, though between 16 and 18 they can ask a court to set aside a transaction that was prejudicial to them.
Marriage at 16
established Scots law has long allowed people to marry at 16 without parental consent. After the English Marriage Act of 1754 required parental consent for those under 21 in England, couples eloped to Scotland, especially to Gretna Green, just over the border. In 2023 England and Wales raised the minimum age of marriage to 18, while in Scotland it remains 16.
Votes at 16
established Sixteen- and seventeen-year-olds voted in the 2014 Scottish independence referendum. The Scottish Elections (Reduction of Voting Age) Act 2015 extended the vote at 16 to Scottish Parliament and local government elections. UK Parliament elections remained at 18.
