(1) The parenting plan, referenced in 40-4-234, MCA, provides for the child's residential schedule with the parents.
(2) When the child resides primarily with one parent and does not spend more than 110 days per year with the other parent, there is no adjustment to the transfer payment due. When at least one child spends more than 110 days per year with both parents, however, or when at least one child resides primarily with each parent, the transfer payment is adjusted according to ARM 37.62.134.
(3) A "day" is defined as the majority of a 24-hour calendar period in which the child is with or under the control of a parent. This assumes there is a correlation between time spent and resources expended for the care of the child. For purposes of this chapter, and unless otherwise agreed by the parents or specifically found by the court, the calendar period begins at midnight of the first day and ends at midnight of the second day. When the child is in the temporary care of a third party, such as in school or a day care facility, the parent who is the primary contact for the third party is the parent who has control of the child for the period of third-party care. If both parents are primary contacts for a third party, or if the parents are otherwise unable to agree on the total number of days for each parent, the number of disputed days may be totaled and divided equally between the parents.
