The Scottish government is considering whether the age at which young people may marry or register a civil partnership should be raised from 16 years old to 18. Writing for Scottish Legal News, Professor Elaine E Sutherland argues that how Scots law addressed the capacity and responsibility of children and young people should be reviewed comprehensively before any action is taken in respect of this fundamental right.
In the closing days of 2025, the Scottish government published its long-awaited Consultation on Family Law. One of the issues it explores is whether the minimum age for entry into marriage and civil partnership should be raised from the current 16 years old to 18; a difficult question on which I confess to being somewhat conflicted.
A striking feature of Scots law is that it empowers children and young people and holds them responsible for their actions at different ages in different contexts. For example, a young person is viewed as being mature enough to have possession of an air rifle at 14 years old (Firearms Act 1968, s.23) but is not trusted behind the wheel of a car until reaching 17 (Road Traffic Act 1988, s.101). A 16-year-old is regarded as ready to participate in shaping the future of the country by voting in Scottish elections (Representation of the People Act 1983, s.2(1A)), yet account will be taken of his or her youth and immaturity while under the age of 25 in sentencing following a criminal trial (Scottish Sentencing Council, Sentencing Young People: Sentencing Guideline, 2022).
This inconsistency in the law is sometimes the result of historical accident and sometimes the product of deliberate policy but, whatever the reason, a thorough review of the Scots law on age, capacity and responsibility is long overdue. Were further support for such a review required, the United Nations Committee on the Rights of the Child (the CRC Committee) recommended taking that step in its most recent Concluding Observations on the UK in 2023 (para.18(a)).
The minimum age for marriage and civil partnership
It is familiar territory that a young person acquires the capacity to marry or register a civil partnership in Scotland at the age of 16 (Age of Marriage (Scotland) Act 1977, s.1; Civil Partnership Act 2004, s.86). In the Consultation on Family Law, the Scottish government asks the question, “Should the Scottish government legislate to raise the minimum age of marriage and civil partnership to 18?” While it simply outlines some of the arguments for and against doing so, one is left with the impression that it is hoping that respondents will answer “Yes”.
At the outset, let me make clear that I do not think that getting married or registering a civil partnership at 16 or 17 is a good idea. In common with most other adults, it is my view that doing so would usually be premature and unwise.
That, however, is not the point. Raising the age for marriage would mean taking a fundamental right – one guaranteed by the European Convention on Human Rights, art. 12 – away from young people, albeit temporarily. Removing any right is a step that should only be taken where a strong case has been made for doing so, balancing protection and autonomy.
What, then, are the arguments advanced for and against raising the age?
Harms associated with early marriage
There is an abundance of evidence that marrying young is associated with a range of adverse consequences, particularly for young women, including dropping out of school; early childbearing and associated infant and maternal health issue and mortality; physical and mental health problems; and an increased risk of domestic abuse. However, much of the research on this was undertaken in jurisdictions in sub-Saharan Arica and on the Indian sub-continent where socio-economic conditions are very different to those prevailing in Scotland. What happens in these countries does not necessarily translate into the domestic setting here.
Were marriage to become unavailable to young people under 18, some would simply cohabit and all the same harms as flow from marriage would follow. In Mexico, for example, raising the age for marriage to 18 led to a reduction in child marriages, but many young women simply lived with their partners, had babies and abandoned formal education (C. Belles-Obrero and M. Lombardi, “Will You Marry Me, Later? Age-of Marriage Laws and Child Marriage in Mexico” (2023) 58 J. Hum. Res. 221).
A further point is worth noting. If the only option for 16 and 17-year-olds in Scotland who want to be together were to become non-marital cohabitation, they would be denied the more extensive rights that they would have had as spouses or civil partners. That would be so even if the proposals for reform of the law on cohabitation, set out in the Scottish Law Commission’s Report on Cohabitation and also discussed in the Consultation on Family Law (paras 1.15-1.77), were to be implemented. In short, by seeking to save young people from some harms, the legal system would be exposing them to others.
