Article 1. Divorce and Annulment.
Sec. 25.24.170. Modification of judgment.

(a) Subject to AS 25.20.110, any time after judgment the court, upon the motion of either party, may set aside, alter, or modify so much of the judgment as may provide for alimony, for the appointment of trustees for the care and custody of the minor children or for their nurture and education, for the care, nurture, and education of unmarried 18-year-old children of the marriage while they are actively pursuing a high school diploma or an equivalent level of technical or vocational training and living as dependents with a parent, guardian, or designee of the parent or guardian, or for the maintenance of either party to the action.
(b) For the purposes of a motion to modify or terminate child support, the adoption or enactment of guidelines or a significant amendment to guidelines for determining support is a material change in circumstances if the guidelines are relevant to the motion. As necessary to comply with 42 U.S.C. 666, a periodic modification of child support may be made without a showing of a material change in circumstances if the child support order being modified on the periodic basis has not been modified or adjusted during the three years preceding the periodic modification.
