Emancipation
Emancipation is a court process in which a minor may be legally declared an independent adult. Massachusetts General Laws do not specify who is eligible for emancipation in the state. Typically, a minor must file a petition with the court and present his or her case at hearing before a judge will grant emancipation.

Contracts
In most circumstances, a contract will be invalid if one party to the contract is a minor. Massachusetts recognizes a few exceptions for necessaries and education, motor vehicle liability insurance (if age sixteen or older), and life insurance (for age 15 or older). (Massachusetts General Laws Chapter 175 sections 113K and 128 and court decisions). (Ch. 175 §§113K, 128, common law)

Ability to Sue
By next friend, representative, or guardian ad litem (R. Civ. Pro. 17(b))

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)
