Stand by. I'll find the law. I think this is going to be a long thread!
Utah law states that marriage at the age of 18 years and above does not require parental consent. For those aged 16-17, parental consent is necessary. For those 15 years old, the following requirements must be met:
• Parental consent must be obtained.
• Approval from Juvenile Court is necessary. The court must conclude that the marriage is voluntary and in the best interests of the minor.
