The rule for changing support in Alaska

A material change of circumstances is presumed if support figured under Rule 90.3 today is more than 15% higher or lower than the current order. A change in custody that changes the formula also counts. An order not changed in the last 3 years can be reviewed without showing a change. Past-due support cannot be changed retroactively; a new amount starts only after the motion or CSED notice is served.

Law: Alaska R. Civ. P. 90.3(h); AS 25.24.170(b)
