Arizona Legal Ages Laws

Parents say, “They grow up so fast.” Kids say, “Not fast enough.” Although parents and their children may disagree on when teens are finally "grownups," the law is generally clear on defining minors and adults. Here is a quick introduction to legal age laws in Arizona.

Age of Majority in Arizona

Arizona recognizes 18 as the "age of majority," or the age at which state residents are legally considered adults, as do most other states. But state laws also govern a minor's eligibility to become emancipated, give consent to medical treatment, and other legal matters. Arizona legal ages laws allow minors as young as 16 petition the court for emancipation and may enter into a contract to pay for college tuition if 17 or older.

Arizona Age Statutes

Age laws and limits can vary from state to state. The following table highlights some of Arizona's legal ages laws.

Age of Majority

18 (§1-215)

Eligibility for Emancipation

Not specified


Contracts by Minors

Governed by common law (§47-1103); at 16 or over may contract for educational loans (§44-140.01); May make contracts if veteran or married (§44-131)

Minors' Ability to Sue

By guardian or special administrator, guardian ad litem, next friend (§A.R.S.R. Civ. Pro. 17(g))

Minors' Consent to Medical Treatment

If homeless, married, or emancipated (§44-132 et seq.)

Age limits for different activities such as marrying, voting, or consuming alcohol can vary, from state-to-state and within the same state. As an example, a fourteen-year old might be held liable (meaning they can be sued) for intentionally injuring someone else or damaging property. At the same time, he or she might not be allowed to drink until age 21 or vote until age 18. These variances reflect societal values on minors’ decision-making and responsibility.

Legal Responsibilities of Minors and Parents

The emancipation of a minor refers to the legal process by which a minor becomes an adult in the eyes of the law. After emancipation, a minor is responsible for his or her own wellbeing and can make all of the major decisions regarding healthcare, school, and other matters. Parental liability for a child’s welfare generally extends until the child is 18 or is emancipated.
