Like most courts, Idaho uses the best interests of the children standard when deciding child custody. The court shall consider all relevant factors, which may include:
The court may order child support to either or both parents until the child is eighteen (18) years of age. If the child continues his/her high school education subsequent to reaching the age of eighteen (18) years, the court may order the continuation of support payments until the child discontinues his/her high school education or reaches the age of nineteen (19) years, whichever is sooner.
All child support orders shall notify the obligor that the order will be enforced by income withholding.
