Child Marriage Laws by State 2025

Child marriage is defined as any marriage or similar union, formal or informal, where one or both of the parties are under 18 years old. While the child in the marriage can be a girl or boy, a majority of child marriages are between a minor girl and a man. Around the world, 12 million girls are married before the age of 18 every year.

Child marriage, usually forced, happens in all different countries, cultures, and religions. It is increasingly being viewed as a form of child sexual abuse and some international organization s have declared it as a human rights violation. Child marriage is fueled by gender equality, poverty, traditions, and insecurity. Studies done in Africa and South Asia showed that the root causes and exacerbating factors that contribute to child marriage are traditions and gender-discriminatory norms rooted in patriarchal views and ideologies.

In most U.S. states, the minimum marriage age for minors that have parental consent ranges from 12 to 17 years old. California and Mississippi do not have set minimum ages for minors to marry with parental consent. Some states have separate minimum ages for males and females, with or without parental consent. Massachusetts has the lowest minimum marriage ages with parental consent of 12 for girls and 14 for boys.
