Massachusetts Legal Ages Laws

Massachusetts 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. Massachusetts legal ages laws allow minors ages 12 or over who are certified as drug dependent to consent to appropriate medical care.

The following table highlights some of Massachusetts's legal ages laws. See Emancipation of Minors and Parental Liability Basics to learn more.

Age of Majority 18 (Ch. 231 §85P)
Eligibility for Emancipation Not specified
Contracts by Minors No, except for necessaries and education; 16 or over for motor vehicle liability insurance; 15 or over for life insurance (Ch. 175 §§113K, 128, common law)
Minors' Ability to Sue By next friend, representative, or guardian ad litem (R. Civ. Pro. 17(b))
Minors' Consent to Medical Treatment If 12 or over and certified to be drug dependent, may consent to appropriate medical care (Ch. 112 §12E); minor may also consent to emergency care when: married, widowed, divorced; is a parent; is a member of armed forces; lives separately from parents and manages own financial affairs; has come into contact with dangerous public health disease; is pregnant (Ch. 112 §12F)
