Minnesota Legal Ages Laws

State law dictates what age individuals must be to get married, enter contracts, take out student loans, or make other legal decisions. Those under the "age of majority," or minors, are considered incapable of making such decisions in the eyes of the law.

The state of Minnesota recognizes the age of majority as age 18. When a minor reaches age 18, they are considered an adult thereafter. State laws also govern a minor's ability to become emancipated from their parents or legal guardians, give consent for medical treatment, purchase and consume alcohol, and other legal matters.

This article provides a brief overview of the legal age statutes in the state of Minnesota.
