The age of majority in MOST states is 18, but be sure to check which state(s) you are concerned with as the age differs in some states. The following link lists the age of majority in all states in the U.S.; however, confirm that the information is current as laws are constantly changing. When states created their age of majority it was based on when a person was no longer under the supervision and dependency of his/her parents. Therefore, the person could enter into contracts, live on their own and also take on the responsibilities of adulthood. Thanks for writing us.
