Created by FindLaw's team of legal writers and editors | Last updated March 10, 2018

Parents say it all the time about their children: “They grow up so fast!” And the kids always respond: “Not fast enough.” So where does the legal system draw the line between minors and adults? Here's a brief summary of legal age laws in Maryland.

Age of Majority in Maryland

Most states, including Maryland, have minor laws that state that 18 is the "age of majority," which is the age at which a citizen is considered an adult in the eyes of the law. Minors, or those under the age of 18, still have certain rights and responsibilities. As an example, under Maryland law, a 16-year old can consent to treatment for an emotional disorder.

Legal Responsibilities of Minors and Parents

There is a legal process, called the emancipation of a minor, by which a minor can become an adult in the eyes of the law. Although the age of majority in Maryland is 18, emancipation can allow for a minor as young as 15 to be responsible for his or her own decisions regarding school, healthcare, and other matters. In most cases, until they are emancipated or they turn 18, juveniles will normally be treated as such in criminal cases, including age and status offenses.
