Age of majority refers to the age at which a person is legally recognised as an adult, capable of exercising full legal capacity without parental responsibility or court-appointed guardianship. In England and Wales, Scotland and Northern Ireland, the age of majority is 18, principally under the Family Law Reform Act 1969, the Age of Majority Act (Northern Ireland) 1969 and related legislation. In Ireland, it is 18 under the Age of Majority Act 1985. Reaching the age of majority generally enables a person to enter binding contracts, sue and be sued in their own name, consent to medical treatment, make a valid will (subject to statutory exceptions), and manage property and finances. The concept is used across civil, family, commercial and procedural law, and is distinct from other age thresholds, such as the criminal age of responsibility, age for marriage, voting, or specific capacity tests under mental capacity legislation. In practice, lawyers must check both the relevant jurisdiction and any specific statutory regime, as certain contexts (for example, adoption, care leavers, or trusts) may modify rights and obligations beyond or below the general age of majority.
