N.D. Cent. Code § 14-10-07

A minor, while under the supervision or custody of the juvenile court or the superintendent of the North Dakota youth correctional center, may not marry without the order of the juvenile court or of the superintendent of the North Dakota youth correctional center, as the case may be. Any such marriage made without such order is subject to annulment in a proceeding brought in district court by the state's attorney or by any person authorized by law to bring such annulment action. A person knowingly aiding, abetting, or encouraging such marriage is guilty of a class A misdemeanor.
