In Pennsylvania, the age requirement for a marriage license is 18, but there are exceptions. Teenagers between the ages of 16 and 17 can get legal married if they win consent from a parent or guardian. (In Maria's case, her mother gave her consent.) Those ages 15 or younger can get a marriage license "if a court decides it is in the applicant's best interest, and [has] parental consent," according to a memo by the state's senators.
