The court shall allow the adjustment in cases where the noncustodial parent proves by a preponderance of the evidence that an adjustment of the child support order is in the best interest of the child who has reached the age of majority.

(b) A noncustodial parent petitioning the court for an adjustment under this section shall adhere to the requirements of W.S. 20-2-311.
