Delegating school decisions. A pupil with a disability who is at least eighteen but under twenty-two, has not been declared legally incompetent, and gives informed consent may delegate the right to make educational decisions to a parent or agent. The delegation is notarized, lasts no more than one year though it may be renewed each year until twenty-two, and the pupil may end it at any time.

Support past eighteen. If a child reaches the age of majority while attending high school or a certified high school equivalency program, support continues while the child is actually attending, but only until the child reaches nineteen years of age. A court may order support past the age of majority for a child with severe mental or physical disabilities, shown by being unable to live independently and be self-supporting, where the disability began before the age of majority.

Ages set for specific purposes elsewhere, such as buying alcohol or tobacco and some licenses and permits, and emancipation before eighteen, are not on this page. How a particular age rule applies to a particular person is a question for a licensed Arizona attorney.
