Article 1. Support Of Minor Child of California Family Law Code >> Division 9. >> Part 2. >> Chapter 1. >> Article 1.

Subject to this division, the father and mother of a minor child have an equal responsibility to support their child in the manner suitable to the child's circumstances.

(a) 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.
  (b) Nothing in this section limits a parent's ability to agree to provide additional support or the court's power to inquire whether an agreement to provide additional support has been made.

The court may direct that an allowance be made to the parent of a child for whom support may be ordered out of the child's property for the child's past or future support, on conditions that are proper, if the direction is for the child's benefit.
