Is child marriage ever legal in North Dakota?
Yes.
Child marriage is legal in North Dakota under limited circumstances. State law sets the minimum age to marry at 18. However, 16- and 17-year-olds may marry with the consent of a parent or legal guardian. Individuals younger than 16 may not legally marry in the state.

North Dakota law requires a minor seeking to marry to provide proof of age and written consent from a parent or guardian. A marriage license may not be issued unless these statutory requirements are met.
In 2019, North Dakota enacted House Bill 1450, which eliminated marriage for individuals under 16, even with judicial approval. Since then, only 16- and 17-year-olds may legally marry, and only with parental consent.
Sixteen states in the U.S. have bans against marriage under the age of 18, while 34 allow it.
