How Long is a Parent Expected to Pay Child Support?

In Arizona, a parent has the legal obligation to pay child support until his/her child reaches 18 years of age or graduates high school, whichever comes later, but not beyond age 19. In other words, if a child is still attending full-time school when s/he reaches age 18, support would contineu until the child graduates high school or turns 19, whichever occurs later. Courts may order a support obligation continue after age 18 or 19 for a child whio is disabled and unikely to be able to be self-supporting.
