In Arizona, a person under the age of 18 years is said to be an emancipated minor if the person: (1) has entered into a valid marriage (case law: [Crook vs. Crook, 80 Ariz 275, 296 P.2d 951 (1956)) ; or (2)is on active duty in any armed forces; or (3)willingly lives apart from his/her parents with the parents' consent and manages his/her own financial affairs regardless of the source of income; or has had an official court ruling stating that the minor is emancipated.
In Arizona, emancipated minors are considered competent contractual parties. Occasionally, you will see the term infant used when referring to a unemancipated minor. These two terms are used interchangeably in most situations.
