Oregon Legal Ages Laws

It seems like the oldest battle between parents and their children: Mom and dad say, “They grow up so fast!” Meanwhile the kids are always saying, “Not fast enough!” It’s the constant back-and-forth of when to treat our kids like adults. But what does the legal system have to say on the matter? Where does the law draw the line between minors and adults? This is a brief overview of legal age laws in Oregon.

Age of Majority in Oregon

States have their minor laws designating the "age of majority," or the age at which a citizen is considered an adult in the eyes of the law. For just about every state, the default age is 18. Minors under the age of 18 still retain certain rights and responsibilities in specific circumstances. For instance, a 14-year old can consent to mental health treatment under Oregon law.

Legal Responsibilities of Minors and Parents

Most states have a legal process whereby a minor can become an adult in the eyes of the law. This is normally called the emancipation of a minor, can allow for a minor under the age of 18, and as young as 14, to be responsible for his or her own decisions regarding healthcare, education, and other matters. Before a juvenile is emancipated or turns 18, he or she will normally be treated as such in criminal cases, including age and status offenses.
