Marriage Age Laws in the UK: Complete Guide to Legal Requirements

The UK has significantly strengthened its laws around marriage age to protect children from forced and underage marriages. The Marriage and Civil Partnership (Minimum Age) Act 2022, which came into effect on 27 February 2023, represents the most significant change to marriage age laws in decades, raising the minimum age to 18 and introducing serious criminal penalties for those who facilitate underage marriages.

Current Legal Marriage Age in the UK

As of 27 February 2023, the legal minimum age for marriage and civil partnerships in England and Wales is 18 years old with no exceptions. This represents a significant change from previous legislation that allowed 16 and 17-year-olds to marry with parental consent.

Key Changes Under the New Law

  • Minimum age raised to 18: No person under 18 can legally marry or enter a civil partnership
  • No parental consent exception: Previously allowed exceptions for 16-17 year olds with consent have been removed
  • Criminal penalties introduced: Facilitating underage marriage is now a criminal offense
  • Religious ceremonies included: The law applies to all forms of marriage, including religious and cultural ceremonies

Background: Previous Marriage Age Laws

Before the 2022 Act came into force, the legal framework was more complex:

Pre-2023 Requirements

  • Age 16-17: Could marry with parental consent from those with parental responsibility
  • Court permission: If parental consent was refused, young people could seek court approval
  • Age 18+: Could marry without any parental consent required
  • Legal loophole: The 16-17 age bracket was often exploited for forced marriages

Problems with Previous System

  • Vulnerable young people forced into marriages against their will
  • Cultural and religious pressure used to justify underage marriages
  • Limited legal protection for teenagers in abusive family situations
  • International marriages used to circumvent UK protections

While respecting cultural and religious diversity, the law prioritizes child protection and gives young people the time and maturity needed to make informed decisions about marriage. The comprehensive approach, including support services and enforcement mechanisms, provides a robust framework for preventing child marriage while supporting those who may be at risk.
