Iron Man: Pretty sure Stark has never died. Captain America: Cap was killed when he was shot after losing out the long-drawn registration battle against Stark and the government (the conclusion to the Civil War arc in Fallen Son: The Death of Captain America). But he wasn't actually dead.
Minors (individuals under age 18) and people who are mentally incompetent do not have the legal capacity to enter into contracts. All other people are considered to have the legal capacity to enter into contracts. In New Mexico and most states, the legal age for entering into contracts is 18 (see NMSA Â§28-6-1). A contract between a minor and an adult may be cancelled upon request of the minor, but is binding on the adult.
In all states, a person has reached the age of majority and is a legal adult at the age of 18. A minor can also be emancipated, or declared a legal adult, by the court. In some states, people as young as 15 may be able to contract for necessities like food and shelter as well as education and car expenses. For example, in Alabama, a minor over the age of 15 may purchase health, life and auto insurance. In New Jersey, a married 17-year-old may sign property contracts.
