Minnesota Issue Guide
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.
  • Publication: Youth and the Law: A Guide for Legislators, by the Minnesota Legislature's House Research Department.
