Another issue that troubles many parents when they get caught up in a child support battle is how long their duty to support lasts. California Family Code § 3901 covers the duration of duty for support.
Section 3901 (a) states: “The duty of support imposed by Section 3900 continues as to an unmarried child who has attained the age of 18 years, is a full-time high school student, and who is not self-supporting, until the time the child completes the 12th grade or attains the age of 19 years, whichever occurs first.” In In re Marriage of Hubner, 94 Cal.App.4th 175, 114 Cal.Rptr.2d 646 (2001), the court determined that a child is not required to graduate high school as soon as possible or required to take only those courses necessary to graduate from high school in order to maintain eligibility for child support.
