Legal Age in Minnesota
This guide is compiled by staff at the Minnesota Legislative Reference Library on a topic of interest to state legislators. It introduces the topic and points to sources for further research. It is not intended to be exhaustive.
Getting Started on Legal Age Research
- Index: The Minnesota Statutes link directly to statutes that deal with AGE and MAJORITY (AGE). Minnesota Statutes, section 645.451 provides general definitions for the terms minor, adult, minority, majority, legal age, and full age.
- Definition: "Age of majority" is the legal age established under state law at which an individual is no longer a minor and, as an adult, has the right and responsibility to make certain legal choices. It is also the most common trigger for terminating child support payments. In most states, the age of majority is 18; however, it is commonly extended for youth still in high school.

- History: Prior to 1973, the drinking age was the age of legal adulthood (age of majority), which was 21 (Minnesota Statutes 1971, section 645.45). In 1973, the age of majority was lowered from 21 to 18. This dropped the drinking age to 18 (Laws of Minnesota 1973, chapter 725, effective June 1, 1973). The legal drinking age was raised to 19 in 1976 (Laws of Minnesota 1976, chapter 66, effective September 1, 1976). The drinking age was raised to the current age of 21 in 1986 (Laws of Minnesota 1986, chapter 330). It included a grandfather clause: persons who were 19 years old by September 1, 1986 were treated as 21 year olds for liquor law purposes.

Emancipation of a Minor
- Background: Emancipation means that a minor has the same legal rights and obligations as an 18-year-old adult. The Minnesota Statutes do not provide either the grounds or a procedure for emancipation. Minnesota case law has established that a minor can be emancipated by a legal marriage or by parental consent. For additional information see, Youth and the Law: A Guide for Legislators, p. 54-55.
