In New York State, a child is entitled to be supported by his or her parents until the age of 21. However, if the child is under 21 years of age, and is married, or self-supporting, or in the military, the child may be considered to be "emancipated" and the parents' support obligation may end.
A child may also be considered "emancipated" if he or she is under 21, leaves the parents' home and refuses to obey the parents' reasonable commands.
